GM vehicle reliability rankings at a glance
Recent GM vehicle reliability rankings from major studies such as the J.D. Power U.S. Vehicle Dependability Study and Consumer Reports show that General Motors' brands now cluster near or above the industry average, with Buick, Cadillac, and many Chevrolet and GMC models scoring among the most dependable in their segments. However, these same rankings also expose one consistent weak spot: technology-related systems, especially infotainment and instrument clusters, which remain the single most frequent source of owner-reported problems across GM's lineup.
How GM ranks in current reliability studies
- The 2025 J.D. Power Vehicle Dependability Study evaluated 34,175 original owners of 2022 model-year vehicles after three years of ownership, measuring "problems per 100 vehicles" (PP100).
- All four GM brands-Buick, Cadillac, Chevrolet, and GMC-finished inside the top 10 of the 30 rated brands, with Buick taking the top Mass Market brand position and tying for second overall behind Lexus.
- Chevrolet ranked fourth among mass-market brands and fifth overall, with products such as the Chevrolet Corvette and Chevrolet Silverado taking category-best dependability awards.
- GMC came in fifth among mass-market brands and seventh overall, with the GMC Acadia earning the top slot in the Upper Midsize SUV segment.
- Historically, GM brands have averaged roughly 120-140 PP100 in recent years, below the industry average of about 152 PP100, indicating that GM dependability has improved faster than the broader market.
A model-by-model snapshot: GM's reliability leaders
When you zoom into specific GM model reliability rankings, several products repeatedly surface as dependability standouts. Industry-tracking data from 2022-2025 model years shows that large trucks and SUVs in the Chevrolet and GMC stables-such as the Chevrolet Silverado, Chevrolet Tahoe, and GMC Yukon-tend to rank first or second in their respective segments for three-year dependability. Luxury-oriented products like the Cadillac XT6 and Buick's midsize SUVs also score near or above segment averages, with Buick claiming the "Overall Mass Market Nameplate" award in the 2025 study.
Below is an illustrative reliability table that mirrors the structure of recent J.D. Power rankings, using realistic but simplified scores to show how GM models compare within and across segments.
| Model | Segment | PP100 (3-year) | Rank vs. Segment Average |
|---|---|---|---|
| Chevrolet Corvette | Premium Sporty Car | 85 | Best in segment |
| Chevrolet Silverado | Large Light Duty Pickup | 98 | Best in segment |
| Chevrolet Tahoe | Large SUV | 104 | Best in segment |
| GMC Acadia | Upper Midsize SUV | 110 | Best in segment |
| Cadillac XT6 | Upper Midsize Premium SUV | 118 | Best in segment |
| Buick Enclave | Midsized SUV | 125 | Above segment average |
| Industry average | All vehicles | 152 | Baseline |
These figures suggest that many core GM vehicles today are not only competitive but are often category leaders for dependability, particularly in the truck and large-SUV segments.
What GM's reliability rankings reveal about brands
Brand-level reliability rankings indicate that GM's four main marques now operate on a surprisingly tight spectrum of quality. Buick consistently outperforms the industry, posting the lowest PP100 scores among mass-market brands and earning the "Overall Mass Market Nameplate" title in 2025. Cadillac sits in the upper tier of premium brands, with dependability scores just behind Lexus and Genesis but still well inside the "above average" band.
Chevrolet and GMC occupy mid-high territory, with both brands scoring above the 152 PP100 industry baseline even though they sell millions of trucks and SUVs in harsh real-world conditions. This tight clustering of GM brands around or above average suggests that the company's global quality systems have delivered a more uniform reliability experience across divisions, rather than one brand bearing the brunt of quality issues.
The one consistent weak spot: technology and interiors
Despite strong overall scores, GM reliability rankings expose one recurring Achilles' heel: technology and interior electronics. In the 2025 J.D. Power study, infotainment, navigation, and in-vehicle communications systems accounted for roughly one-fifth of all owner-reported problems, a pattern that aligns with earlier industry-wide trends. Within GM's own data, voice-recognition glitches, touchscreen freezes, and software update failures show up disproportionately in the Chevrolet and GMC truck lines, even when drivetrain and chassis components rank near the top of their segments.
Diagnostic and repair reports from independent data-sharing sites further highlight instrument clusters and associated gauges as a GM reliability weak spot. Owners of Chevrolet Silverados and Trailblazers have reported repeated failures of the instrument panel around the 60,000-70,000-mile mark, often requiring entire cluster replacements at a repair cost of roughly 400-500 dollars. On the Chevrolet Tahoe, dashboard cracking in hot climates has also emerged as a recurring cosmetic and structural issue, illustrating how interior materials and electronic integration can undermine otherwise solid GM truck reliability rankings.
This improvement coincided with investments in global quality systems, tighter supplier oversight, and a shift toward more standardized platforms and powertrains. As a result, GM's 2022-2025 model years now show dependability scores that not only beat the industry average but also rival or surpass many Japanese and Korean competitors in specific segments, particularly in full-size trucks and large SUVs.
How to use GM reliability rankings when buying a car
When navigating GM vehicle reliability rankings, buyers should follow a structured approach rather than relying on brand-wide averages alone. Start by consulting the latest J.D. Power Vehicle Dependability Study to identify which specific GM models rank first, second, or third in their segments for three-year dependability. Then cross-check those models against Consumer Reports' predicted reliability scores, keeping an eye out for any "below average" or "poor" designations, especially in recent model years.
- Identify your target segment (e.g., midsize SUV, full-size pickup) and pull the corresponding J.D. Power segment rankings for that category.
- Shortlist the top two or three GM vehicles in that segment, then compare their PP100 scores and owner-reported issue patterns.
- Check independent owner-complaint databases and recall histories for specific model years that interest you, focusing on drivetrain, brakes, and interior electronics.
- For used vehicles, obtain a vehicle-history report and a pre-purchase inspection, paying special attention to the GMC or Chevrolet instrument cluster and infotainment systems, which are known weak spots.
- Consider warranty coverage and service-plan options from GM dealers, since extended coverage can offset residual risk in higher-tech packages.
Key concerns and solutions for Gm Vehicle Reliability Rankings Just Flipped Expectations
Which GM models are most reliable?
Among current GM model rankings, the Chevrolet Corvette, Chevrolet Silverado (including Silverado HD), Chevrolet Tahoe, GMC Acadia, Cadillac XT6, and select Buick SUVs consistently finish in the top three of their segments for three-year dependability. Consumer Reports' predicted reliability data for 2025-2026 models also singles out the Chevy Trax subcompact SUV and the Corvette as "excellent" in long-term reliability projections, while larger trucks and SUVs sit in the "average to above average" range.
Which GM models should buyers watch out for?
Recent used GM vehicle analyses from Consumer Reports flag several Chevrolet nameplates for below-average predicted reliability, including the 2025 Equinox and 2025 Colorado. Independent owner-report databases similarly highlight older Chevrolet Impalas and Malibus as among the most complaint-prone GM vehicles, with recurring issues in power steering, electrical systems, and emissions components. Buyers shopping the used market should therefore cross-check specific model year rankings against both J.D. Power dependability data and Consumer Reports' long-term reliability scores.
How do GM reliability rankings compare to Toyota and Honda?
GM reliability rankings today place the automaker in the upper half of the field, but still slightly behind Toyota and Honda in aggregate quality. Toyota and Honda continue to lead the J.D. Power dependability charts, with PP100 scores in the mid-90s to low-100s, compared with GM's current band of roughly 110-130 PP10 obscuring some model-level outliers. However, GM's improvement over the past decade-moving from well above the industry average to near or below it-shows that the gap has narrowed meaningfully, especially in the truck and SUV segments where GM pickups now rival Toyota and Ford for dependability.
How much has GM's reliability improved over the last decade?
GM's climb in reliability rankings over the last ten years is one of the most notable turnaround stories in the auto industry. In the late 2000s and early 2010s, GM brands trailed behind Honda and Toyota with more than half of their nameplates falling at or below average, according to Consumer Reports' annual surveys. By the mid-2010s, GM had reversed that trend: by 2016-2017, roughly 69% of GM models were rated average or better in reliability, and 83% of Chevrolets scored at or above average.
What does PP100 mean for GM vehicles?
PP100 stands for "problems per 100 vehicles" and is the primary metric used in J.D. Power's Vehicle Dependability Study to quantify long-term reliability. A lower PP100 score indicates fewer owner-reported problems, so a GM model scoring 85 PP100 is significantly more dependable than the industry average of 152 PP100. In practice, this means that out of every 100 owners of that model, fewer than 90 will report a problem over three years, compared with roughly 150 problems across 100 vehicles for an average brand.
Are GM luxury vehicles as reliable as their mass-market siblings?
GM's luxury GM brand rankings show that Cadillacs and Buicks are now almost as reliable as their Chevrolet and GMC counterparts, though they still carry a small premium in reported issues. The Cadillac XT6, for example, ranks first in the Upper Midsize Premium SUV segment with a PP100 score in the low-120s, just a few points above the best-in-class Chevrolet and GMC models. Buick's mass-market luxury positioning has helped it post the lowest overall PP100 among volume brands, suggesting that GM's luxury quality systems have benefited from the same platform-standardization and process improvements that lifted Chevrolet and GMC.
Will electric GM vehicles be as reliable as gas models?
GM electric vehicle reliability is still emerging, but early data suggests that GM's EVs track closely with the dependability of their internal-combustion siblings when it comes to core hardware. The Chevrolet Bolt EV and its EUV variant have posted strong long-term reliability scores in Consumer Reports' surveys, with battery and drivetrain issues being relatively rare compared with other EVs. However, software-related problems-such as infotainment bugs and charging-interface glitches-mirror the same technology-related weak spot seen in GM's gas-powered trucks and SUVs, underscoring that GM's biggest challenge lies in electronic integration rather than propulsion systems.
How reliable are GM trucks and SUVs compared with cars?
Across GM truck and SUV rankings, trucks and large SUVs consistently outperform GM's passenger cars in long-term dependability. The Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, and GMC Yukon all rank first or second in their respective truck and SUV segments, with PP100 scores in the high-90s to mid-100s. In contrast, GM's compact and midsize cars-such as the Chevrolet Malibu and older Impala-show higher PP100 values and more frequent owner complaints, particularly around electrical and suspension components.
What should buyers watch for in a GM vehicle's service history?
When reviewing GM service history, prospective buyers should pay particular attention to recurring issues tied to the brand's known weak spots. Look for patterns of repeated visits for infotainment resets, instrument cluster recalibrations, or software updates, as these often signal underlying electronic flaws that may reappear after the warranty expires. Also note any major repairs to the power steering, emissions, or HVAC systems, which have historically been trouble spots on certain Chevrolet and Buick models. A clean, well-documented service file-especially one showing consistent use of GM-authorized dealers-can help mitigate some of the residual risk from GM's remaining reliability weaknesses.
