At what mileage the Chevrolet Silverado 1500 failed
| Component group | Median | Reports |
|---|---|---|
| Service Brakes | 50,000 | 182 |
| Power Train | 53,500 | 80 |
| Electrical System | 42,500 | 53 |
| Steering | 41,000 | 76 |
| Engine | 48,368 | 32 |
| Suspension | 10,000 | 25 |
| Wheels | 8,637 | 17 |
| Structure | 30,000 | 13 |
| Electronic Stability Control (ESC) | 48,000 | 16 |
Across all components, half the reported failures happened before 45,250 miles, with the middle half falling between 22,000 and 66,525. Based on the 462 complaints (66%) that record a mileage.
A low figure does not mean the car stops working at that mileage. It means the reported failures clustered early, which most often points to a fault built into a production batch — usually the kind of thing a warranty repair or a recall campaign addresses.
How this mix compares with other model years
| Component group | Here | Typical |
|---|---|---|
| Engine | 7.7% | 16.6% |
| Electrical System | 14.1% | 13.4% |
| Power Train | 22.3% | 10.2% |
| Unknown or Other | 10.3% | 10.2% |

| Air Bags | 2.1% | 5.8% |
| Fuel/Propulsion System | 3.6% | 4.5% |
This compares the subjects of the complaints, not how many there are. A share needs no denominator, so unlike a count it can honestly be held against a norm — but a group sitting above the typical share means people complained about that part more often relative to everything else on this car, not that the car is worse than another.
How serious the complaints were
- 5.3% Crash reported 37 of 701
- 1.1% Fire reported 8 of 701
- 1.3% Injury reported 9 of 701
- 0.1% Death reported 1 of 701
Reported across all complaints on file: 12 injuries and 1 death. These shares sit within this model’s own complaints — they say nothing about how it compares to another model.
Recall campaigns
11 campaigns. A recall repair is free at a dealer regardless of how many owners the car has had. Check the car’s own VIN — a campaign listed here may already have been carried out on it.
21V504000 Air Bags: Side/Window: Curtain: Inflator July 1, 2021
General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
Consequence: A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Remedy: Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022. Phase II owner notification letters are expected to be mailed on May 31, 2022. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. This recall supersedes NHTSA recall number 20V-736. GM's number for this recall is N202324251.
Campaign covered 410,019 vehicles across model years 2015, 2016 — a count for the whole campaign, not for this model year alone.
21V245000 Seat Belts: Front April 8, 2021
General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
Consequence: A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.
Campaign covered 2,568 vehicles across model years 2014, 2015, 2016 — a count for the whole campaign, not for this model year alone.
20V736000 Air Bags: Side/Window: Curtain: Inflator November 25, 2020
General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500 and Chevrolet Silverado 1500 and 2015 GMC Sierra 2500 and 3500, and Chevrolet Silverado 2500 and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator.
Consequence: If the end cap separates from the inflator, the compressed gas will escape and the end cap can be propelled into the vehicle, increasing the risk of injury or a crash.
Remedy: GM will notify owners, and dealers will replace the RRAB modules on the left and/or right side, free of charge. Interim owner notification letters were mailed on December 22, 2020. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. Note: GM filed a new recall, number 21V-504 that supersedes this recall. All vehicles previously recalled under 20V-736 will now be repaired under the new recall number 21V-504. GM's numbers for this recall are N202309680, N202309681, and N202309682.
Campaign covered 9,279 vehicles across model years 2015, 2016 — a count for the whole campaign, not for this model year alone.
19V761000 Electronic Stability Control (ESC) · Service Brakes · Service Brakes, Hydraulic: Antilock/Traction Control/Electronic Limited Slip: Wheel Speed Sensor/Tone Ring October 24, 2019
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Consequence: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
Campaign covered 652,967 vehicles across model years 2014, 2015, 2016 — a count for the whole campaign, not for this model year alone.
19V645000 Service Brakes, Hydraulic: Power Assist: Vacuum September 6, 2019
General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
Consequence: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.
Campaign covered 3,456,719 vehicles across model years 2014, 2015, 2016 — a count for the whole campaign, not for this model year alone.
18V578000 Service Brakes, Hydraulic: Pedals and Linkages August 30, 2018
General Motors LLC (GM) is recalling certain 2015-2016 Chevrolet Silverado 2500, 3500, 1500 Crew Cab Special Service, Tahoe Police Pursuit/Special Service, GMC Sierra 2500, and 3500 vehicles. The brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative.
Consequence: If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a crash.
Remedy: GM will notify owners, and dealers will add adhesive to the nut and reinstall the nut with increased tightness, free of charge. The recall began October 3, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 18278. Note: The vehicles in this recall need this additional remedy despite being covered by recall 16V069 for brake pedal loosening.
Campaign covered 42,280 vehicles across model years 2015, 2016 — a count for the whole campaign, not for this model year alone.
18V291000 Seat Belts: Front May 3, 2018
General Motors LLC (GM) is recalling certain 2015-2016 Chevrolet Silverado 1500 and Tahoe Police Pursuit and Special-Service vehicles. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
Consequence: If the pretensioner cable becomes fatigued or breaks, the driver may not be properly restrained in the event of a crash, increasing their risk of injury.
Remedy: GM will notify owners, and dealers will replace the pretensioner cable and seat side-shield, free of charge. The recall began June 19, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 18156.
Campaign covered 23,004 vehicles across model years 2015, 2016 — a count for the whole campaign, not for this model year alone.
17V437000 Air Bags: Frontal · Air Bags: Frontal: Sensor/Control Module-inactive · Seat Belts: Pretensioner July 10, 2017
General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.
Campaign covered 40,683 vehicles across model years 2014, 2015, 2016 — a count for the whole campaign, not for this model year alone.
16V651000 Air Bags: Frontal · Air Bags: Frontal: Sensor/Control Module-inactive · Seat Belts: Pretensioner September 8, 2016
General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on October 13, 2016. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 16007.
Campaign covered 3,640,162 vehicles across model years 2014, 2015, 2016 — a count for the whole campaign, not for this model year alone.
16V256000 Suspension: Front: Control Arm April 28, 2016
General Motors LLC (GM) is recalling certain model year 2016-2017 Chevrolet Silverado 1500 and 2016 Cadillac Escalade, Cadillac Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, GMC Yukon and GMC Yukon XL vehicles. The front upper control arms may have inadequate welds near the control arm bushing.
Consequence: Inadequate welds may allow the control arm to separate from the bushing, compromising steering and increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the left and right front upper control arms and realign the vehicle, free of charge. The recall began on May 18, 2016. Until the repairs have been made, owners are advised not to drive their vehicles. Owners may contact Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782. GM's number for this recall is 42190.
Campaign covered 3,738 vehicles across model year 2016 — a count for the whole campaign, not for this model year alone.
16V069000 Service Brakes, Hydraulic: Pedals and Linkages February 5, 2016
General Motors LLC (GM) is recalling certain model year 2015-2016 Chevrolet Silverado 1500, 2500, and 3500 heavy duty trucks manufactured October 1, 2013, to February 1, 2016, 2015-2016 Chevrolet Tahoe Police Pursuit Vehicles (PPV) manufactured March 1, 2014, to February 1, 2016, and 2015-2016 GMC Sierra 2500 and 3500 heavy duty trucks manufactured October 29, 2013, to February 1, 2016. On the affected vehicles, the brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative.
Consequence: If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a crash.
Remedy: GM will notify owners, and dealers will add adhesive to the brake pedal pivot nut and reinstall with an increased torque, free of charge. The recall began on March 14, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 20760.
Campaign covered 430,771 vehicles across model years 2015, 2016 — a count for the whole campaign, not for this model year alone.

Pre-purchase inspection checklist
Written and checked by someone who does this work; it is not derived from the data. The complaint counts decide only the order: the assemblies this model’s owners complain about most come first.
Brakes
Related complaint groups: Service Brakes (254)
With the car parked
- Brake fluid level and color. Clear yellow is fresh; dark brown has not been changed in a long time.
- Fluid at the lower mark with no leaks usually means worn pads: the pistons have extended and the fluid has moved into the calipers.
- Pad thickness through the spokes of the wheel. Check the disc for a lip at the outer edge and for deep scoring.
- Inside face of the wheels: an even dark dust film is normal; one wheel noticeably dirtier than the others may indicate a sticking caliper.
- Hoses for cracks and bulges, lines for corrosion.
On the road
- First stop at low speed: the pedal should be firm, with no sinking.
- Accelerate to 40–45 mph and brake moderately. Pulsing through the pedal or the steering wheel usually means warped discs.
- Braking on flat dry pavement: pulling to one side requires further inspection.
- The ABS light should come on with the ignition and go out after the engine starts.
- A feeling that the car is driving "as if towing a trailer" may indicate binding brakes.
- The car squatting at the rear when pulling away may indicate parking-brake cables or stuck rear shoes.
After the drive
- Hold your palm near each wheel without touching the disc or the caliper — after braking they will burn you. Compare only left against right on the same axle: the front is always hotter than the rear, and that is normal. A noticeable difference between the two wheels of one axle requires further inspection.
Red flags
- The pedal slowly sinks to the floor when held down
- An illuminated ABS or brake system warning light
- Fresh fluid together with completely worn pads
Cost if it needs work: Moderate. Confirm actual cost against local prices at the time of purchase.
Automatic transmission
Related complaint groups: Power Train (156)
Checking the fluid level during an inspection is usually not possible — many cars need a lift, some have no dipstick at all, and Honda’s procedure differs from the rest. So this assessment is built on behavior, not on fluid.
With the car parked
- Move the selector P → R → D and back with the brake held. Each engagement should be a soft nudge, without a thump and without delay. Repeat two or three times in each direction.
On the road
- Shifts without noticeable delay or thump, both under acceleration and when slowing down.
- Pay particular attention to the 1-2-3 and 3-2-1 transitions — they carry the most load.
- Hard acceleration at full throttle: the revs should not flare without the car gaining speed.
- On a CVT the revs should rise smoothly, without steps, droning or jerking.
Questions for the seller
- Has the fluid been changed, and is there proof. Regular changes are a substantial plus for the car; their absence at high mileage is reason for caution.
Red flags
- A stored transmission fault code (a scan tool is worth having)
- Slipping under load in any form
- Recently cleared codes with no explanation
- The seller offering to "just change the fluid" when it is black and burnt — that is cosmetic cover over wear that has already happened
Cost if it needs work: Expensive. The most expensive of the likely assemblies; a repair is often comparable to the value of the car.
Axles and CV joints
Related complaint groups: Power Train (156)
With the car parked
- Turn the steering to full lock and inspect the outer CV boots on both sides for cracks, splits and thrown grease on the inner face of the wheel and in the wheel arch. A split boot on a joint that is still sound is a cheap repair today and an expensive one in six months.
On the road
- Empty parking lot, steering at full lock, slow circles in both directions. A rhythmic clicking points to an outer CV joint; the side is identified by the direction of the turn.
- Vibration under acceleration in a straight line that disappears when you lift off may indicate an inner CV joint.
Cost if it needs work: Relatively low. A good indicator of how the car has been treated overall.
Suspension, control arms, steering
Related complaint groups: Steering (95), Suspension (28)
With the car parked
- Rock the steering wheel briskly left and right. Knocking and free play point to ball joints, tie rod ends or the rack. This is the most productive check of this assembly without a lift.
- Rock each wheel at 12 and 6 o’clock (ball joint, wheel bearing) and at 3 and 9 o’clock (steering linkage).
- Inspect the bushings for cracks and separation, and the ball joint boots for damage.
On the road
- Dull knocking from the front over small bumps. The cause cannot be determined without a lift: sway bar links are inexpensive, control arms cost several times more, and by ear the two are indistinguishable. A knock is grounds to require an inspection on a lift before purchase — not grounds to walk away from the car.
- Whether it pulls to one side on a level road, and whether the wheel returns to center after a turn.
Red flags
- Uneven tread wear — almost always alignment
- A recent alignment in the paperwork with no explanation of why
- One control arm noticeably newer than the rest
Cost if it needs work: Low to moderate. Depends on what turns out to be the source. Plus an alignment after the replacement.
Electrical system
Related complaint groups: Electrical System (99), Exterior Lighting (14)
With the car parked
- With the ignition on, before starting, every warning light should come on and then go out once the engine runs. None coming on at all is worse than one staying lit: the bulb may have been removed or disabled in software.
- Click through everything: windows from every switch, mirrors, heated elements, climate control on all settings, the radio, the camera, the parking sensors, cruise control.
- Every exterior light, including running lights, brake lights, side repeaters and the license plate lamp.
- Battery terminals for corrosion, and the date on the battery.
- Cabin and trunk for signs of water: damp carpet under the mats, condensation in the headlights, rust on the seat mounts. Water in the electrics causes faults that are extremely hard to trace.
On the road
- Whether anything dims when several high-draw consumers are switched on at once.
- A second hot start after the drive.
Red flags
- A dashboard with no warning lights at all when the ignition is on
- Signs of water ingress
- Homemade wiring, twisted joints, tape under the dash
- Several small non-working functions at once — usually one common root cause
Engine and cooling system
Related complaint groups: Engine (54)
Come to a cold car. A warmed-up engine hides a hard start, smoke and knocking. If the car is already warm, that is a yellow flag: ask for 30–40 minutes to let it cool. A refusal to let it cool is a red flag.
With the car parked
- Oil: level, color, consistency. Level above maximum plus a smell of fuel on the dipstick means the oil is being diluted with fuel.
- A whitish film on the oil filler cap alone is usually condensation from short trips in cold weather, not cause for alarm. What matters is the dipstick: a coffee-with-milk emulsion on the dipstick requires serious further inspection. A further indication is coolant hoses that are hard and under excess pressure.
- Coolant: level, color, no oil film. Open the reservoir only on a fully cooled engine.
- Leaks: under the engine, along the sump seam, around the valve cover, along the hoses and the radiator.
On the road and after
- Cold start: how long the starter cranks, smoke in the first seconds, knocking that goes away as it warms up.
- Temperature over the whole drive. Idle with the air conditioning on: the fan should cut in and the needle should not climb.
- After the drive, switch off, wait a couple of minutes and look for fresh drips under the car.
Red flags
- A freshly washed engine bay on a high-mileage car
- Thick white smoke after warm-up
- Temperature climbing in traffic
Airbags and the VIN recall check
Related complaint groups: Air Bags (15), Seat Belts (8)
The most reliable procedure in this library — it does not depend on hearing, experience or inspection conditions.
Required procedure
- Take the VIN from the car itself — the windshield on the driver’s side, the door pillar, the paperwork — not from the listing.
- Check that VIN in NHTSA’s official recall lookup.
- A recall repair at a dealer is free regardless of how many owners the car has had. An open recall is a reason to visit a dealer, not a reason to haggle.
- An open airbag recall is grounds not to buy the car until it has been fixed.
Inspection
- The SRS light should come on with the ignition and then go out. Not coming on at all probably means it has been disabled deliberately.
- Airbag covers on the wheel and dash: uneven gaps, mismatched texture, marks from removal.
- Seat belts: pull each one out to full length and check for chafing, tears and water marks. The inertia reel should lock when pulled sharply.
The Chevrolet Silverado 1500 year by year
| Model year | Complaints | Median mileage | Recalls |
|---|---|---|---|
| 2014 | 1,346 | 62,000 | 6 |
| 2015 | 987 | 52,000 | 11 |
| 2016 (this page) | 701 | 45,250 | 11 |
Read the mileage column down this table with care. A newer year has simply been driven less, so its median sits lower for that reason alone — the figure is censored from above by how long the cars have been on the road, not only by how they were built. The same applies to the complaint counts: an older year has had more years in which to collect them.
Where the mileage figure does compare cleanly is between different models of the same year, which have had the same time to accumulate miles.
