Chevrolet vs GMC Lemon Law Problems: What California Owners Report

Published October 19, 2026 · Updated October 19, 2026 · California lemon law

Which has more lemon law problems in California, Chevrolet or GMC?

Side-by-Side Comparison

Same Manufacturer, Two Badges

Chevrolet and GMC are both General Motors brands. For a California lemon law claim, the company usually named is the same for either one: General Motors LLC. That makes this comparison different from most brand matchups, where two separate manufacturers are involved.

Several models are close siblings. The Chevrolet Silverado 1500 and GMC Sierra 1500 are related full-size pickups. The Tahoe and the Yukon are related full-size SUVs. Shoppers often choose between them based on styling, trim and price rather than mechanical differences.

Because the manufacturer is the same, the claim process is the same too. Warranty repairs go through franchised dealers, the repair orders are your main evidence, and the same Song-Beverly rules apply. What can differ is the defect itself, how often it was repaired, and how long the vehicle was in the shop.

One practical note: many GMC dealers are combined Buick GMC stores, and some Chevrolet owners live closer to one kind of store than the other. Your warranty repairs should go to a dealer authorized to do warranty work for your brand. Ask before you book a visit.

What California Chevrolet Owners Report

California owners of 2019 to 2027 model year Chevrolets filed 996 NHTSA complaints between 2021 and 2026. The electrical system had 191 complaints and the engine had 175. Brakes (117), the transmission and powertrain (113) and steering (64) filled out the top five.

The Silverado 1500 had 191 complaints, the most of any Chevrolet. The Bolt EV had 124, the Traverse 89, the Tahoe 83 and the Equinox 68. Chevrolet's list mixes trucks, SUVs and an electric hatchback, so its complaints come from a wide range of vehicles.

San Diego (34) and Los Angeles (33) were nearly tied for the most Chevrolet complaints. San Jose had 16, Sacramento 15 and Bakersfield 13.

Chevrolet's list is broader than GMC's, partly because Chevrolet sells more kinds of vehicles. The Bolt EV is the clearest example: an electric hatchback with 124 complaints sits right behind the Silverado 1500.

Steering (64) is the fifth area for Chevrolet and does not appear in GMC's top five. Steering faults, like a wheel that suddenly gets heavy or a vehicle that wanders, can be treated as safety defects, which can lower the number of repair attempts needed for the presumption.

• Electrical system: 191 complaints
• Engine: 175 complaints
• Brakes: 117 complaints
• Transmission and powertrain: 113 complaints
• Steering: 64 complaints

What California GMC Owners Report

GMC owners in California filed 383 NHTSA complaints for the same model years and filing period. The engine led clearly with 134 complaints, more than twice the next category. The transmission and powertrain had 54, the electrical system 49, brakes 37, and lights, cameras and visibility 17.

The Sierra 1500 had 163 complaints, which is a large share of GMC's total. The Yukon had 52 and the Yukon XL 41. The Acadia (29) and Canyon (27) completed the list. GMC complaints are heavily weighted toward full-size trucks and SUVs.

GMC's city list is unusual. Bakersfield led with 16 and Fresno was second with 12. San Jose had 8, Sacramento 7 and Los Angeles 7. Two Central Valley cities at the top suggests that GMC's California owner base, or at least its reporting owners, lean toward truck country.

The engine figure is the clearest difference between the two badges. For Chevrolet, the engine is second, just behind electrical. For GMC, the engine is first by a wide margin. Since the Sierra 1500 and Silverado 1500 are related trucks, an owner of either with a recurring engine problem may find similar reports under both names.

Engine Problems and How the Presumption Works

Engine problems in full-size trucks and SUVs can range from noises and warning lights to oil consumption, misfires and stalling. California's lemon law does not list specific parts. It asks whether a warranty defect that substantially impairs use, value or safety was not fixed after a reasonable number of attempts (Civil Code 1793.2(d)(2)).

Within 18 months or 18,000 miles, a reasonable number of attempts is presumed if a defect likely to cause death or serious injury was repaired 2 or more times, if the same defect was repaired 4 or more times, or if the vehicle was out of service more than 30 days in total (Civil Code 1793.22(b)).

An engine that stalls or loses power while driving can be a serious safety risk. Make sure the repair order says so in plain words. A vague line like "customer states noise" is much weaker evidence than "engine shut off at 55 mph on Highway 99."

If the manufacturer's failure to fix the vehicle is willful, a court can add a civil penalty of up to two times actual damages (Civil Code 1794(c)). Whether that applies depends on the facts and is something to discuss with an attorney.

Example: A Yukon With a Recurring Engine Warning

This is an invented example for illustration only. Kevin bought a new Yukon in Fresno for his family. At 6,000 miles, the check engine light came on and the engine began to shake at idle. The dealer replaced a sensor.

The light and shaking returned twice over the next four months. On the third visit, the dealer said the problem matched a technical service bulletin and replaced a valve part. The SUV was in the shop 14 days that time. A fourth visit followed after the engine lost power on the freeway.

Kevin kept every repair order and asked the dealer for a copy of the TSB reference it listed. He sent a written notice to General Motors LLC because his owner's manual asked owners to contact the manufacturer. He also kept rental car receipts from the long visit.

At his free case review, the attorney counted four attempts for the same engine defect inside 18 months and looked at whether the loss of power made it a safety defect. The attorney noted that his mileage offset would be based on the miles at the first visit, not today's miles.

Had Kevin driven a Tahoe instead, the analysis would have looked the same. The badge on the grille would change, but the manufacturer, the dealer network and the rules would not.

Why 996 vs 383 Does Not Mean One Badge Is Worse

Chevrolet has more than twice as many California complaints as GMC in this data. That is expected. Chevrolet sells more models and more vehicles overall, including cars and an EV, while GMC focuses on trucks and SUVs. More vehicles on the road means more reports.

Reporting habits also vary by region and by owner. Truck owners in the Central Valley who rely on their vehicles every day may report problems differently from city commuters. Some owners never file with NHTSA at all.

NHTSA complaints are owner reports, not verified defects. They are useful for spotting which systems owners talk about most. They do not rank brands, and they do not decide whether your truck or SUV qualifies under the lemon law. Your repair history does.

The Sierra 1500 and Silverado 1500 show this well. The Silverado has 191 complaints and the Sierra has 163. Those two numbers are closer than the brand totals, because those two pickups are the core of each badge's sales in this data. Comparing a related truck to a related truck is more useful than comparing a whole lineup to a whole lineup.

If your own problem matches the most-reported area for your badge, that may help you describe it clearly at the dealer. If it does not, that is fine too. A rare defect that is repaired over and over can qualify just as well as a common one.

Documents to Gather for a General Motors Claim

Since both badges lead to the same manufacturer, the checklist is the same for Chevrolet and GMC owners. If you used more than one dealer, ask each one for a full service history printout tied to your VIN.

If you win, General Motors LLC pays your attorney fees, costs and expenses (Civil Code 1794(d)). Warranty claims generally must be filed within four years (Commercial Code 2725). Keep paying your loan or lease while the claim is open.

Read the repair orders closely. Each one should list the date in, date out, mileage, your complaint and the repair. If a visit is missing a date out, or the complaint is written in a way that does not match what you said, make a note now. Your attorney can request the dealer's internal records later, but your own notes help fill gaps.

If the engine or another safety system is acting up, think about whether the vehicle is safe to drive. If it is not, have it towed to the dealer and keep the tow receipt. Restitution can include reasonable towing and rental costs as incidental damages.

• You own a GMC Sierra 1500 and the problem keeps coming back

Key Facts (as of October 2026)

• Complaint counts are California owner reports to NHTSA for 2019 to 2027 model years, filed 2021 to 2026. They are not verified defects and are not adjusted for sales.
• Both brands' most-reported areas include the engine.
• For either brand, a reasonable number of repair attempts is presumed within 18 months or 18,000 miles after 2 tries for a serious safety defect, 4 tries for the same defect, or more than 30 days in the shop (Civil Code 1793.22(b)).
