Your Chevy Silverado keeps stalling on the freeway. Your GMC Sierra’s transmission slips every time you merge. You’ve been back to the dealer three, four, maybe five times — and nothing sticks. You’re not being picky. You have a lemon, and California law gives you real options.
General Motors is one of the highest-volume automakers in the state. That means Chevy and GMC vehicles make up a significant share of the lemon law claims filed in California every year. If your truck, SUV, or sedan keeps coming back with the same defect, here’s everything you need to know about Chevy lemon law California: what qualifies, when to file, and what to expect when you do.
What Makes a Chevy or GMC a Lemon Under California Law
Under Chevy lemon law California rules, the governing statute is the Song-Beverly Consumer Warranty Act. It requires manufacturers to repair any defect that substantially impairs the use, value, or safety of your vehicle. If GM can’t fix the problem after a reasonable number of attempts, they owe you a buyback or a replacement.
The law applies to new vehicles purchased or leased in California and used primarily for personal, family, or household purposes. It also covers vehicles still under the original manufacturer’s warranty, including not just the window sticker warranty but any express warranty GM provided at the time of sale.
So what counts as “a reasonable number of repair attempts”? That’s where the statute gets specific.
The Lemon Law Presumption: Your Best Leverage in a GM Claim
Cal. Civ. Code § 1793.22, also called the Tanner Consumer Protection Act, sets up a legal presumption in your favor. Under this provision, your vehicle is presumed to be a lemon if any of the following are true:
- The same defect has not been fixed after two or more repair attempts, and the defect could cause death or serious bodily injury
- The same defect has not been fixed after four or more repair attempts
- Your vehicle has been out of service for more than 30 cumulative days due to repairs
Once you hit one of those thresholds, the burden shifts. GM has to prove the defect doesn’t substantially impair your vehicle — not the other way around.
That shift matters enormously. The court in Krotin v. Porsche Cars North America, Inc., 38 Cal. App. 4th 294 (1995) made clear that once the statutory presumption kicks in, it is the manufacturer who carries the burden of rebutting it, not the consumer. GM’s lawyers know this. It’s a big part of why cases that meet the threshold often settle before trial.
You don’t need to hit all three thresholds. One is enough.
Common Chevy and GMC Defects in California Lemon Law Claims
GM vehicles consistently rank among the top makes for lemon law complaints in California. Based on what we see and what NHTSA complaint data reflects, these are the most frequently reported issues in Chevy lemon law California cases.
Transmission problems top the list, particularly in Silverado, Sierra, and Equinox models. Shuddering, slipping, hesitation between gears, and complete failure after multiple “reprogramming” attempts are all common complaints. Dealers often reprogram the transmission control module and hand the car back, only for the shudder to return within weeks.
Electrical and infotainment failures are a close second. The GM infotainment system freezes, reboots mid-drive, or loses Bluetooth connectivity. Dealers replace modules and the problem comes back.
Engine stalling and misfires are reported across multiple Chevy and GMC platforms, often tied to fuel system issues or defective AFM (Active Fuel Management) components that cause oil consumption and misfires over time.
Brake defects, including soft pedals, premature rotor wear, and ABS malfunctions, show up frequently in larger GM trucks and SUVs. Suspension and steering issues (clunking, pulling, or wandering) also appear frequently, even when dealers log them as “within normal operating characteristics.” These round out the pattern.
If you’ve been told any of these are normal, push back. A qualified Chevy lemon law California attorney will dig into your full repair history and tell you what the records actually show.
Does a GMC Lemon Law Buyback Work the Same Way?
Yes. Chevy and GMC are both General Motors brands. Whether you’re pursuing a Chevy lemon law claim or a GMC case, the same Song-Beverly standards govern the claim, and the same remedies are available: a full buyback or a replacement vehicle.
A GMC lemon law buyback means GM repurchases your vehicle. You get back the full purchase price, including down payment, monthly payments made, registration fees, and incidental costs, minus a deduction for the miles you drove before the first repair attempt related to the defect. That deduction is called a mileage offset, and it’s calculated based on early mileage relative to the vehicle’s expected 120,000-mile lifespan.
What most people don’t realize: manufacturers calculate that mileage offset aggressively. Without an attorney reviewing the math, it’s easy to accept a buyback number that’s lower than what the law actually entitles you to.
A replacement means GM provides a comparable new vehicle of the same or similar make, model, year, and features in exchange for your lemon. Some clients prefer this option, especially if they love the vehicle type and just want one that works.
Either way, under California law, GM pays your attorney’s fees separately. Not you.
When to File a GMC or Chevy Lemon Law Claim
Don’t wait until your warranty expires. The clock matters.
You have four years from the date you discovered the defect to file a GMC or Chevy lemon law California claim under Song-Beverly. That sounds like plenty of time, but the longer you wait, the more complicated your case becomes. Repair records go missing. Dealers claim the vehicle has aged out of relevance.
File when you’ve hit the presumption thresholds, or even before, if the defect is serious and you have documented repair attempts. You don’t need to reach the magic number to have a valid GMC or Chevy lemon law California claim; the presumption just makes it easier to win.
If your dealer has been refusing to acknowledge the problem or keeps returning your car “fixed” with the same issue unresolved, that pattern alone supports your case. Document every visit. Keep every repair order. Note the date, your mileage, what you complained about, and what the dealer said they did — or didn’t do.
What to Expect When You File
Here’s a realistic look at the process for a Chevy or GMC lemon law claim in California.
In the first week or two, you contact an attorney. We review your repair records and confirm whether you have a qualifying lemon law California case. If you do, we send a pre-suit notice to GM formally demanding a buyback. This is a step now required under California’s updated lemon law rules.
Over the following weeks, GM responds. In many cases, they come to the table with a settlement offer during this period. We evaluate it against what you’re actually owed and advise you whether to accept or push further.
If GM doesn’t settle, we file in court. Most cases resolve before trial, but we prepare every case as though it’s going all the way. That preparation is what produces better results. Throughout this process, you keep driving your vehicle if you choose. Filing a claim doesn’t require you to surrender your car.
We’ve recovered hundreds of thousands of dollars for California clients with GM vehicles. The case results on our homepage include a $165,750 recovery on a brake and dashboard defect, a $58,000 recovery on an infotainment defect, and settlements against nearly every major automaker. GM is not exempt, and they know it.
