Keystone Montana Lemon Law in California: Your Rights
If your Keystone Montana, Alpine, Avalanche, Fuzion or Raptor keeps returning to the shop, California lemon law may apply. The Song-Beverly Consumer Warranty Act can require the manufacturer to repurchase or replace a defective unit it could not fix under warranty. A willful violation can add a civil penalty on top. Recurring sidewall cracks near the slideouts are one of the best documented problems on these fifth wheels, and they are the kind of defect this law was written for.
This guide explains what the law covers, what Keystone’s own warranty says, how the new AB 1755 deadlines work, and what to do next.
TL;DR
- California’s Song-Beverly Act covers consumer goods, including towable RVs such as fifth wheels. A manufacturer that cannot repair a covered defect may have to replace the unit or reimburse the purchase price, less a deduction for your use.
- Keystone issued a service bulletin for sidewall cracks on 2020 and 2021 Montana, Montana High Country, Alpine, Avalanche, Fuzion and Raptor fifth wheels. Repeated cracking after repair attempts is worth documenting.
- Keystone’s structural warranty covers exterior sidewalls and slideout structures, but not damage after delivery.
- AB 1755 and SB 26 changed filing deadlines and added a 30 day pre-suit notice for civil penalty claims. Waiting can cost you rights.
- Our contingency fee means you pay nothing out of pocket. The manufacturer pays statutory attorney fees if the claim succeeds.

Does California lemon law cover a Keystone Montana?
Yes, in most cases a Keystone fifth wheel falls under Song-Beverly as a consumer good. A legislative analysis explains that the act applies to consumer goods including trailers, and its general provisions reach non-motorized RVs such as fifth wheel travel trailers. The same analysis notes that the Tanner Act’s refund or replacement choice for motor vehicles does not extend to those units.
That distinction matters. A motorhome is a motor vehicle. A Montana, Alpine or Avalanche is a towable. The legal route differs, and so does the evidence we build.
Most lemon law firms turn these cases away because RVs carry several warranties: the chassis maker, the coach builder and component suppliers. We handle them every day. You can see how we approach each type on our pages for fifth wheel lemon law, travel trailer lemon law and motorhome lemon law.
What is the sidewall crack problem on Keystone fifth wheels?
Keystone itself documented cracking in the sidewall near the front slideouts. Its service bulletin KSB 210122 lists 2020 to 2021 Montana, Montana High Country, Alpine, Avalanche, Fuzion and Raptor fifth wheels and describes a repair procedure. It says only units that develop a crack need the repair.
The repair is not small. The procedure calls for removing the slideout, the front cap and roofline moldings, and inspecting the sidewall tubes for wood. It also calls for adding long screws and reinforcing the area.
That tells you three things:
- The manufacturer knew the pattern existed.
- The fix involves opening up the structure, so the unit can sit at a service center for weeks.
- A cracked sidewall can let water in, which can lead to delamination and rot.
The bulletin lists model years 2020 and 2021. Owners of other years can still have a claim if the facts fit, but the bulletin is not proof for them. Related water damage is covered in our guide to RV delamination and California lemon law.
Can sidewall cracks support a lemon law claim?
They can, if the defect is covered by warranty and the repairs have not worked. Keystone’s warranty guide says its structural warranty covers exterior sidewalls and slideout structures for manufacturing or assembly defects. It does not cover post-delivery damage such as collision or misuse.
The central question is cause. Keystone may argue that you caused the crack by overloading the pin, driving on rough roads or lowering the landing legs wrong. We expect that argument. A repeating crack in the same spot, on the same model family, after the same bulletin repair, is hard to blame on one owner.
A sound claim usually has these elements:
- A written warranty that was in effect when you reported the defect.
- A defect that substantially impairs the use, value or safety of the RV.
- A reasonable number of repair opportunities with an authorized facility.
- Repair orders showing the defect stayed unfixed.
What does Keystone’s warranty cover, and for how long?
Keystone’s 2026 warranty guide gives a one year base warranty and a three year structural warranty. Montana and Montana High Country units manufactured after January 1, 2026 get five years of structural coverage. Coverage runs from the first retail purchase.
The guide defines a defect as a failure of workmanship or materials to match Keystone’s specifications. It excludes routine maintenance and water leaks caused by failing to maintain exterior seals.
That last exclusion is where many owners get denied. Keystone may say a leak is a sealant problem. Keep your maintenance records and photos of the seals. Our broader look at warranty denials is in what to do when a dealer refuses to fix a vehicle under warranty.
Keystone also says its structural warranty does not guarantee future performance. It also limits consequential damages such as loss of use or lodging costs, though these limits may vary by state law. California law can override a limit that conflicts with it.
How many repair attempts or days in the shop matter?
California sets a presumption of a reasonable number of attempts for new motor vehicles. The state’s consumer affairs department says it applies when, within 18 months or 18,000 miles, the same problem remains after four attempts, a serious safety problem remains after two attempts, or the vehicle is in the shop more than 30 days.
Those numbers are written for motor vehicles, and a fifth wheel is not one. Even so, they are a useful yardstick for any RV claim, and they are the numbers we track when we review a motorhome. For a towable, courts look at whether the manufacturer had a reasonable chance to fix the defect and failed. You do not need to hit a specific count.
Two habits protect you:
- Count days from the day you drop off the unit to the day you pick it up, not the days of actual labor.
- Keep every repair order, even when the dealer writes “could not duplicate.”
Our guides explain the repair attempt standard and the 30 day repair shop claim in more detail.
What can you recover from Keystone?
You recover money or a replacement, not just repairs. For non-motorized RVs treated as consumer goods, the manufacturer may replace the item or reimburse the purchase price, less an amount for your use before the defect appeared. Willful failure to comply may support a civil penalty.
In our practice the possible results are:
- A repurchase or refund of the unit.
- A replacement RV.
- A cash settlement while you keep the unit.
- A civil penalty of up to two times actual damages when the manufacturer willfully ignored its warranty.
- Attorney fees paid by the other side.
No lawyer can promise any of these. Each depends on your records, your warranty and the facts. We explain the money side in RV lemon law claim benefits for California owners.
What do AB 1755 and SB 26 mean for your deadline?
The deadline is shorter than it used to be if the manufacturer opts into the new procedures. AB 1755 set new procedures effective January 1, 2025. SB 26, effective April 2, 2025, lets manufacturers elect to use them for five consecutive calendar years.
For an electing manufacturer, an action must generally be filed within one year after the express warranty expires. It must also be filed no later than six years after original delivery. Civil penalty claims require written notice at least 30 days before filing.
Governor Newsom’s signing statement explained that automakers opposed AB 1755 as unworkable. He described a compromise that lets automakers elect whether to use the new procedures. So whether the shorter clock applies to you depends on whether Keystone has elected in.
Do not wait to find out. Read our guides to the AB 1755 deadline, how AB 1755 shortens claim time and the one year filing window and six year cap.
How do you send Keystone the pre-suit notice?
Send it in writing, by email or by certified or registered mail. Keystone’s warranty guide says that to seek a civil penalty you must give notice by emailing CaliforniaPreSuitNotice@keystonerv.com or mailing Keystone RV Company, c/o California Pre-suit Notice, PO Box 2000, Goshen, Indiana 46527, as set out in its 2026 warranty guide.
We recommend that an attorney prepare the notice. The wording, the list of defects and the repair history all shape what Keystone can later say it did not know.
Should you use Keystone’s dispute program first?
You can, but you do not have to, and it does not stop your clock. Keystone participates in a third party warranty dispute program administered by DeMars and Associates that offers owners mediation support.
Mediation can resolve a minor warranty dispute. For a structural defect that has been to the shop several times, it rarely gives you a refund. Keep your deadlines running while you try it. The state’s New Motor Vehicle Board also runs a consumer mediation program with jurisdiction over recreational vehicles.
Can you pursue the dealer, not just Keystone?
Sometimes. A dealer is not the same target as the manufacturer, and the claims differ. Under Song-Beverly, every retail sale of a consumer good carries the manufacturer’s and the retail seller’s implied warranty of merchantability, unless it was properly disclaimed. That can matter when a dealer sold you a unit with a defect it should have caught.
A lemon law claim goes after the manufacturer’s failure to repair under the express warranty. A dealer claim turns on what the dealer knew and said. If a dealer hid known damage or misdescribed the unit, that can be fraud. We cover this in our dealer fraud practice and in five deceitful practices in car and RV dealer fraud.
Perspective: what 11 years defending manufacturers taught us
We spent 11 years on the other side, so we know how a manufacturer prepares a file like yours. The first move is almost always to look for a reason the defect is your fault. The second is to argue that the repairs worked, even when the unit returned for the same problem.
On a sidewall crack case, we expect the manufacturer to point to seals, loading and use. Because we have built those defenses, we know which records answer them. Photos at drop off, dated repair orders and your maintenance log matter more than any single phone call.
We also see owners lose months with firms that never put an attorney on the phone. Large advertising driven firms often run cases through case managers. At our office you talk to the attorney. We also take RV cases that others call too complex.

FAQ
Does California lemon law cover Keystone Montana fifth wheels?
Generally yes, as a consumer good under Song-Beverly. A towable such as a Montana is treated under the act’s general provisions, not the motor vehicle refund rules. An attorney should review your warranty and purchase documents.
Do sidewall cracks on a Keystone Alpine or Avalanche count as a lemon law defect?
They can. Keystone’s structural warranty covers exterior sidewalls and slideout structures for manufacturing defects. Repeated cracking after repair attempts is strong evidence, but damage you caused after delivery is not covered.
How long do I have to file a lemon law claim on my RV?
It depends on whether the manufacturer elected the AB 1755 procedures. If it did, the action generally must be filed within one year after the express warranty expires and within six years of delivery. Speak to an attorney early to protect your claim.
What do I get if my Keystone is a lemon?
You may receive a refund of the purchase price less a use offset, or a replacement unit. A willful violation may add a civil penalty. Results vary and cannot be guaranteed.
