How long do Chevrolets last?
Complaint records can’t measure how long a car lasts; they show when reported failures happened. Across the 37 Chevrolet generations here — 23 of the 37 generations here left production more than ten years ago, and older ones have had longer to reach high mileage, so read the figure against that mix — half of the 71,248 complaints that record an odometer reading were filed by 69,000 miles and 90% by 140,000 miles. 5,662 came in past 150,000 miles and 1,206 past 200,000 — each one a car that got there, not one that failed there.
At what mileage do Chevrolets start having problems? A quarter of those reports came by 40,000 miles, and 10% within the first 12,000 — the window this site treats as manufacturing defects rather than wear. That is the start of the reports, not the onset of problems on any one car.

What the strips show across Chevrolet
Of the 37 Chevrolet generations here, 34 with failures spread across the mileage range; 3 with failures concentrated early. The shape matters more than the median: a generation whose reports cluster tightly at one mileage is describing a part that fails, while one spread across the whole range is describing ordinary wear, and the two need different decisions from a buyer. The most common shape across this make is failures spread across the mileage range, on 34 of 37.
Comparing generations of the same age
Medians fall as generations get newer, and that is age, not decline: a car built three years ago has not had time to reach a high odometer reading, so its reports cannot come from one. The only honest comparison is inside an age band, and here is this make split into three.
Chevrolet built in the last decade
14 generations, median of medians 49,000 miles. The earliest reports in this band belong to the Equinox 2018–2024 at 17,000, the latest to the Equinox 2010–2017 at 79,000. That is a spread of 62,000 miles between two cars of comparable age, which is a comparison worth making; the same numbers set against a generation from another band are not.
Chevrolet built between ten and twenty years ago
17 generations, median of medians 70,000 miles. The earliest reports in this band belong to the Camaro 2010–2015 at 40,000, the latest to the Malibu 2008–2012 at 86,000. That is a spread of 46,000 miles between two cars of comparable age, which is a comparison worth making; the same numbers set against a generation from another band are not.
Chevrolet older than twenty years
6 generations, median of medians 93,000 miles. The earliest reports in this band belong to the Camaro 1993–2002 at 53,000, the latest to the Suburban 1992–1999 at 96,000. That is a spread of 44,000 miles between two cars of comparable age, which is a comparison worth making; the same numbers set against a generation from another band are not.
Where the reports concentrate
The middle half of the reports — between the 25th and 75th percentile — is the part of the curve that says most. On the Camaro 2010–2015 it spans 50,000 miles, the tightest of any Chevrolet generation here: half the reports arrive inside that window, which is what a single failing part looks like in this data. On the Malibu 2004–2007 the same half spans 74,000 miles — a curve that wide is describing a fleet ageing, not a part failing.
The largest body of evidence for this make is the Cobalt 2005–2010, with 6,579 reports that record an odometer reading. Generations with a few hundred reports describe their own owners more loosely, and every number on this page carries that weight with it.
Model by model
Within one model the generations are the fairest comparison this data allows: same maker, same intent, often the same platform carried forward. Where a median moves sharply between two generations of the same model, it is worth asking whether the newer one is simply younger.
Camaro. 3 generations here, 1993–2024, 1,304 reports with an odometer reading between them. The latest reports belong to the 1993–2002 at a median of 53,000 miles, the earliest to the 2016–2024 at 21,000, a gap of 32,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Colorado. 2 generations here, 2004–2022, 2,057 reports with an odometer reading between them. The latest reports belong to the 2004–2012 at a median of 53,000 miles, the earliest to the 2015–2022 at 38,000, a gap of 15,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Cruze. 2 generations here, 2011–2019, 2,696 reports with an odometer reading between them. The latest reports belong to the 2011–2015 at a median of 54,000 miles, the earliest to the 2016–2019 at 36,000, a gap of 18,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Equinox. 3 generations here, 2005–2024, 5,865 reports with an odometer reading between them. The latest reports belong to the 2010–2017 at a median of 79,000 miles, the earliest to the 2018–2024 at 17,000, a gap of 62,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Impala. 3 generations here, 2000–2020, 7,594 reports with an odometer reading between them. The latest reports belong to the 2000–2005 at a median of 77,000 miles, the earliest to the 2014–2020 at 55,000, a gap of 22,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Malibu. 5 generations here, 1997–2025, 13,671 reports with an odometer reading between them. The latest reports belong to the 2004–2007 at a median of 86,000 miles, the earliest to the 2016–2025 at 49,000, a gap of 37,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Silverado 1500. 5 generations here, 1988–2025, 10,012 reports with an odometer reading between them. The latest reports belong to the 1988–1998 at a median of 93,000 miles, the earliest to the 2019–2025 at 27,000, a gap of 66,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Suburban. 4 generations here, 1992–2020, 3,935 reports with an odometer reading between them. The latest reports belong to the 1992–1999 at a median of 96,000 miles, the earliest to the 2015–2020 at 60,000, a gap of 36,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Tahoe. 5 generations here, 1995–2025, 5,385 reports with an odometer reading between them. The latest reports belong to the 1995–1999 at a median of 94,000 miles, the earliest to the 2021–2025 at 39,000, a gap of 55,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
Traverse. 2 generations here, 2009–2023, 2,846 reports with an odometer reading between them. The latest reports belong to the 2009–2017 at a median of 71,000 miles, the earliest to the 2018–2023 at 37,000, a gap of 34,000 miles. The older of the two has had longer on the road, so part of that gap is age rather than build.
What fails across Chevrolet, and when
Summed across every Chevrolet generation on this site, the most-reported system is Electrical System: 22,461 reports, 20% of the 113,023 that name a system, and it appears among the leading systems on 36 of the 37 generations here, reporting at a median of 69,000 miles.
| System | Reports | Generations | Median of medians |
|---|---|---|---|
| Electrical System | 22,461 | 36 | 69,000 |
| Steering | 18,701 | 25 | 60,000 |
| Engine | 13,521 | 24 | 69,000 |
| Power Train | 11,575 | 29 | 60,000 |
| Air Bags | 10,774 | 15 | 80,000 |
| Other or unspecified | 8,132 | 19 | 49,000 |
| Service Brakes, Hydraulic | 7,938 | 10 | 79,000 |
| Service Brakes | 7,801 | 14 | 54,000 |
The right-hand column is a median of medians, not an average: a generation with three thousand reports and one with two hundred would otherwise carry the same weight in a mean, and they do not describe the same amount of evidence. Read it as the middle of the range this make reports at, not as a prediction for one car.
Recalls across Chevrolet
NHTSA has issued 377 recall campaigns against the Chevrolet generations on this site, spread over 37 of 37. A recall is not a reliability score: it means a defect was found and a free repair is owed, and a make watched closely can collect more campaigns than one nobody examined. What it does mean for a buyer is concrete — the work is free at an authorized dealer, for any owner, and whether a given car is included depends on its VIN rather than on its model year.
- Silverado 1500 2014–2018 — 36 campaigns
- Silverado 1500 1988–1998 — 28 campaigns
- Trailblazer 2002–2009 — 25 campaigns
- Silverado 1500 1999–2006 — 24 campaigns
- Silverado 1500 2019–2025 — 24 campaigns
- Tahoe 2021–2025 — 21 campaigns
What this page cannot tell you
These are complaints, not failures. A complaint exists because an owner chose to file one with NHTSA, and nothing here counts the owners who did not. That makes the counts a measure of reporting as much as of breaking, and it is why this site never ranks one car against another: it describes what happens to a given car, and when.
Nor is any of this a rate. A rate needs a denominator — how many of these cars were sold — and no free model-level production figure exists. The obvious substitute, the affected-vehicle count on recall campaigns, was tested here and rejected: it overstates by a median factor of 7.6, because most campaigns span several model years. So a generation with more reports than another may simply be a generation with more cars on the road. The method page sets out every step.
