Lifted Truck Lemon Law in California: Does a Lift Void It?
A lift kit does not automatically end your California lemon law claim. Under the federal Magnuson-Moss Warranty Act, a manufacturer cannot void your entire warranty just because you installed aftermarket parts. If your truck keeps failing under warranty, you may be able to recover a repurchase or refund, a replacement vehicle or a cash settlement. A willful violation can add a civil penalty of up to two times your actual damages.
The catch is simple. The defect has to be unrelated to the lift, or the manufacturer has to fail to prove the lift caused it. This guide explains how that fight works, how it applies to trucks such as the Toyota Tundra with the V35A engine, and which deadlines you cannot miss.
TL;DR
- A suspension lift does not void your whole warranty. The manufacturer must show the lift or another aftermarket part caused the specific defect.
- Engine, electrical, brake and infotainment problems are the hardest for a manufacturer to blame on a lift. Axle, driveline and suspension problems are the easiest.
- California’s Song-Beverly Consumer Warranty Act can give you a repurchase, a replacement or cash, plus a civil penalty of up to two times actual damages for willful violations.
- AB 1755 added written notice steps and a shorter filing window, so do not wait on a truck that keeps going back to the shop.
- Keep every repair order, receipt and maintenance record, including the lift installation paperwork.

Does a lift kit void my warranty in California?
No. A lift kit alone does not void a manufacturer’s warranty. The Warranty Act says companies cannot deny coverage solely because you used a part made by another company or had service done by someone outside the dealer network.
The manufacturer may still decline a repair when the aftermarket part caused the failure. An FTC advisory opinion confirms that warrantors may exclude damage caused by unauthorized parts. That distinction is where lifted truck cases are won or lost.
The burden matters. The manufacturer or dealer has to connect the specific modification to the specific defect. A service advisor who says “you lifted it, so nothing is covered” is not stating the law.
The FTC also tells owners not to be intimidated by this kind of claim. It advises keeping maintenance records, including oil changes and repairs, as proof the vehicle was properly cared for.
Which defects can a manufacturer blame on a lift?
The closer a defect sits to the lift, the easier the manufacturer’s argument. A lift changes suspension geometry, driveline angles, tire and wheel size and sometimes the gearing the truck sees in real use.
Here is how we sort defects when a lifted truck owner calls.
| Defect area | How easily the lift can be blamed | Why |
|---|---|---|
| Engine oil consumption, internal engine failure | Hard | A lift does not change how the engine burns oil or how its internal parts wear |
| Transmission software, shifting faults | Usually hard | These are control problems, though larger tires can complicate it |
| Brake fluid leaks, brake system faults | Mixed | Fluid and hydraulic defects are hard to tie to a lift, wear on larger tires is easier |
| Door actuators, electronics, infotainment | Hard | These are unrelated to ride height |
| Driveshaft vibration, CV axle failure, ball joints | Easy | Lift angles directly affect these parts |
| Alignment, tire wear, steering wander | Easy | Geometry changes with ride height |
This table is our working framework, not a legal rule. Each truck gets its own analysis.
What does the lift change about a lemon law claim?
The lift changes the evidence, not the law. Song-Beverly still asks the same questions: did the truck have a covered defect, did it substantially impair use, value or safety, and did the manufacturer fail to fix it after a reasonable number of attempts?
A manufacturer in a lifted truck case will usually do three things.
- Point to the lift in the repair orders and ask for a denial.
- Argue the defect came from the modification.
- Use the modification to attack the truck’s value or the owner’s credibility.
We answer each one with records. Repair orders show what the dealer actually diagnosed. Installation paperwork shows when and how the lift went on. Dealer notes often show the defect was already there before the lift or has nothing to do with it.
One practical point: if a dealer technician wrote down a defect and never tied it to the lift, that silence helps you. If a dealer refused repair only because of the lift, that refusal can become part of the claim. Our guide on what to do when a dealer refuses warranty repair in California covers this in detail.
Is the Toyota Tundra V35A engine a lemon law case?
It can be. The 3.5 liter twin turbo V35A engine is used in the current generation Tundra, and owners search for it because of oil consumption, ticking noises and engine failures. Owners also report brake fluid and door actuator problems on several Toyota models.
We will not tell you every V35A truck is a lemon. Whether yours qualifies depends on your own repair history. Three things matter most.
- The defect is documented. Oil consumption that you mention verbally does not count. Oil consumption written on a repair order does.
- The truck is still under warranty when the defect appears. Song-Beverly claims rest on the manufacturer’s express warranty.
- The dealer had a fair chance to fix it. That means repeated visits for the same problem or a long time out of service.
If you own a lifted Tundra, the manufacturer will likely say the lift or oversized tires stressed the engine. That argument is weak for oil consumption, because the lift does not control how an engine burns oil. A manufacturer still has to prove it, and we expect it to be forced to.

What can you recover on a lifted truck?
You recover money, not just repairs. California lemon law gives three paths.
- Repurchase or refund. The manufacturer buys the truck back.
- Replacement. The manufacturer provides a comparable vehicle.
- Cash settlement. You keep the truck and receive compensation.
When a manufacturer willfully ignores its warranty obligations, a civil penalty of up to two times actual damages can be added. No lawyer can promise a result, and we do not. What we can say is that the penalty exists to punish manufacturers that stonewall owners.
Aftermarket parts raise a fair question about refund calculations. The manufacturer will want credit for use and may argue about the lift’s value. We deal with this on a case by case basis, and we want to see your receipts early.
What are the filing deadlines after AB 1755?
The deadline is short, so act early. Under the current statute, an action seeking restitution or replacement must be filed within one year after the express warranty expires, and in all cases within six years of original delivery.
AB 1755 was signed by Governor Newsom on September 29, 2024. It created new procedures for manufacturers that opt in. The statute also requires pre-litigation steps for civil penalties, operative since July 1, 2025.
Before you sue for civil penalties, you must:
- Send the manufacturer written notice with your VIN and a summary of the defects.
- Demand a repurchase or replacement.
- Give the manufacturer 30 days to respond.
- Keep the truck for at least those 30 days.
If the manufacturer makes a valid offer, you must cooperate to complete it within 60 days of the original notice. The statute is the source for these details, and it is worth reading with a lawyer.
After you file, the procedures set initial disclosures within 60 days of the answer and mediation within 150 days of the answer. Legislative analysts said the reforms followed a surge in filings, as the Assembly Judiciary Committee analysis describes.
Manufacturers objected to parts of the reform, and the opt-in structure means the rules you face depend on your manufacturer’s election. That is one more reason to have a lawyer check your facts.
For more on timing, read our AB 1755 lemon law deadline guide and our explanation of what happens when the lemon deadline passes.
Should you sell the lifted truck before the claim is resolved?
Not without advice. Selling too early is one of the most common ways owners damage their own claims.
If the manufacturer does not offer restitution within 30 days of formal notice, the statute allows you to sell the vehicle and still pursue damages. Selling without giving notice, or before the 30 days run, may cost you the civil penalty. If you do sell, you must give the buyer written notice of the defects and the pending claim.
This also affects how you handle the lift. Do not pull the lift kit and throw away the parts before talking to a lawyer. Removing evidence can look like hiding something, and the manufacturer may use it against you.
What records should a lifted truck owner keep?
Keep everything. A clean paper trail neutralizes most lift based denials.
- Every repair order, including ones that say “could not duplicate”
- The dates the truck went in and came out, so days out of service can be counted
- Lift kit receipts, installer name and installation date
- Oil change and maintenance records, as the FTC suggests
- Written and emailed communication with the dealer and with the manufacturer
- Photos or video of the defect, such as warning lights or oil level readings

Our perspective: I used to build the manufacturer’s lift defense
We spent 11 years defending manufacturers and dealerships before we turned to representing owners. That means we know how a lift gets used in a file.
The pattern is consistent. A defense team looks for any modification, photographs it and builds a story around it. In many files the story is thin, because the defect has nothing to do with ride height. The strategy works best on owners who give up the moment they hear the word “aftermarket.”
We also know the reverse. Some lifted truck cases are weak, particularly when the failing part sits in the lifted driveline or suspension. We tell owners that plainly during the free case review, before they commit to anything.
We also built our firm against the lemon law mill model. You should talk to your attorney, not a case manager, and that matters most when the other side will question your modifications.

FAQ
Can a dealer refuse warranty work because my truck is lifted?
Not on that basis alone. The Magnuson-Moss Warranty Act bars a manufacturer from denying coverage solely because of aftermarket parts. The dealer or manufacturer must show the lift caused the failure being repaired. Keep the written denial, because it is evidence.
Does a lifted truck qualify as a lemon in California?
It can. The same test applies as for a stock truck: a covered defect that substantially impairs use, value or safety and that the manufacturer failed to fix after a reasonable number of attempts. The lift matters only if it caused the problem. A lawyer should review your repair history.
Is the Toyota V35A engine oil consumption problem covered by lemon law?
Possibly, if your repair orders document it and the truck is within warranty when it appears. Each case depends on its own records. Bring every oil consumption complaint and dealer response to your case review.
How long do I have to file a lemon law claim in California?
The action must be filed within one year after the express warranty expires, and no later than six years after original delivery. AB 1755 also added notice steps for civil penalties. Do not wait until the end of the warranty to find out where you stand.
