Recurring engine issues on a RAM? California's Lemon Law may entitle you to a full refund or replacement — at no cost to you.
Get a Free Case ReviewIf your Ram is experiencing engine problems that your dealer has been unable to permanently fix, you may be entitled to a full repurchase, replacement vehicle, or cash settlement under California's Song-Beverly Consumer Warranty Act — widely regarded as the strongest lemon law in the United States.
Ram owners across California have successfully recovered the full purchase price of their vehicles after repeated failed repair attempts for engine defects. California law requires Ram to either repair the defect in a reasonable number of attempts or buy the vehicle back — and if the company refuses, it may owe you up to twice the purchase price as a civil penalty.
This page covers everything you need to know: what Ram engine defects qualify, how the lemon law process works, what compensation you can recover, and answers to the questions our clients ask most often. If you've already made multiple dealer visits for the same problem, you may already qualify — read on to find out.
Engine defects that cause stalling, loss of power, oil consumption, or overheating typically constitute a substantial impairment under California law — especially when they affect the vehicle's safety or drivability.
Under California's lemon law presumption, your Ram is presumed to be a lemon if, within 18 months or 18,000 miles from original delivery (whichever comes first), any of the following apply:
You do not need to satisfy all three criteria — any one of them is sufficient to trigger the presumption. And even if you fall short of these thresholds, you may still have a valid claim if the defect is serious enough or the manufacturer's response was unreasonable.
Ram models that have generated engine complaints in California include the Ram 1500, Ram 2500, Ram 3500, ProMaster, and Ram 1500 Classic. If you own one of these models and have returned to the dealer repeatedly for the same issue, your case deserves a professional evaluation.
Engine defects in Ram vehicles manifest in a variety of ways. The following are the most frequently reported issues by Ram owners who have pursued — and won — lemon law claims in California. If your vehicle shows any of these symptoms after multiple repair attempts, you likely have a strong claim.
Many vehicles consume far more oil than the manufacturer's specification, forcing owners to add quarts between changes. When a dealer cannot resolve this after multiple visits, it often qualifies as a lemon law defect.
An engine that stalls without warning — at highway speeds or in traffic — poses an immediate safety hazard. California law treats safety-related defects with heightened urgency.
A persistent check engine light accompanied by recurring fault codes, even after dealer repairs, is a classic indicator of a defect the manufacturer cannot fix.
Misfires cause vibration, loss of acceleration, and poor fuel economy. When caused by a manufacturing defect, repeated repair failures give rise to a lemon law claim.
Engine overheating can cause catastrophic damage. If your cooling system or head gasket fails repeatedly, the manufacturer may owe you a full repurchase.
Premature timing chain wear or belt failure can destroy an engine. Courts have consistently held that early timing system failures qualify under Song-Beverly.
Knocking sounds from the engine block often indicate bearing wear or rod damage — defects that are costly to repair and frequently recur after dealer service.
When a Ram owner reports a engine problem, dealers typically begin with the least invasive steps — diagnostic scans, software updates, fluid changes, or component cleaning — before escalating to part replacement or system overhaul. This incremental approach is common across the industry, but it often means the root cause goes unaddressed over multiple visits while the repair order count climbs.
Dealers often attempt software reflashes, oil additives, or partial disassembly before acknowledging a deeper defect. Each failed attempt counts toward your repair history.
A critical point many Ram owners miss: every service visit counts as a repair attempt — including visits where the dealer documents "no fault found" or "unable to duplicate concern." Those visits still establish that you reported the problem and the manufacturer failed to resolve it. If you have three or four repair orders for the same complaint, your case may already meet the legal threshold.
Organize every repair order chronologically. Note the date, mileage, and the exact complaint you described each time. This paper trail is the backbone of your lemon law case and the first thing an attorney will review.
California's Song-Beverly Consumer Warranty Act applies to new and certain used vehicles purchased or leased in California that come with a manufacturer's express warranty. It requires manufacturers — including Ram — to repair defects that impair the vehicle's use, value, or safety. When those defects cannot be permanently repaired in a reasonable number of attempts, the manufacturer must either replace the vehicle or buy it back.
California's lemon law is significantly stronger than the federal Magnuson-Moss Warranty Act in several important respects:
The law applies to vehicles purchased for personal, family, or household use — including daily commuters. Commercial fleet vehicles are subject to different standards, but single business-use vehicles may still qualify. An attorney can evaluate your specific situation quickly and at no cost to you.
A successful lemon law claim against Ram can result in substantial financial recovery. California law provides three primary remedies:
Ram repurchases the vehicle and refunds: your down payment, all monthly payments made, registration and licensing fees, taxes, and incidental expenses (rental cars, towing, repair-related costs) — minus a mileage offset calculated from delivery date to first reported defect.
Ram provides a comparable new vehicle — same make, model, and trim level — at no net cost beyond the same mileage offset. Replacement vehicles come with a fresh warranty.
Many lemon law cases resolve with Ram paying a negotiated lump sum while you keep the vehicle. For owners who have grown accustomed to their car or cannot wait for a buyback process, this option often delivers immediate value.
Civil Penalty: If a court finds that Ram willfully refused to comply with its buyback obligation, California law allows the court to award up to two times the vehicle's purchase price as an additional civil penalty — on top of the buyback amount.
Attorney Fees: Under Song-Beverly, Ram must pay your reasonable attorney's fees and litigation costs if you prevail. This is what makes the California lemon law work for consumers: you pay nothing to pursue your claim.
If your Ram has a engine defect, the actions you take in the next few days can significantly affect the outcome of your claim. Here is what to do:
Time matters. California's lemon law has a 4-year statute of limitations from when you knew or should have known of the defect — but acting sooner means better documentation, fresher memories, and faster resolution.
California presumes your vehicle is a lemon if the manufacturer or dealer has made two or more repair attempts on a defect that is likely to cause death or serious injury, or four or more attempts on any other defect within 18 months or 18,000 miles of purchase — whichever comes first. Engine stalling at speed is typically treated as a safety defect, lowering the threshold to two attempts.
Yes. Excessive oil consumption is one of the most commonly litigated lemon law defects in California. If your vehicle consumes oil at a rate beyond manufacturer specifications and the dealer cannot resolve it, you likely have a claim — even if the engine itself has not yet seized.
Every time the dealer clears a code and the light returns, that typically counts as a repair attempt. Keep all your repair orders, including ones where the dealer says they "found no fault." Courts consider the pattern of visits, not just formal repair events.
Yes. You are not required to stop driving your vehicle. However, document every issue that occurs — dates, mileage, symptoms — because this evidence strengthens your claim.
Manufacturers often try to attribute engine problems to owner-caused damage (low oil, poor fuel, aggressive driving). A lemon law attorney can counter these arguments with the repair history and manufacturer's own diagnostic reports.
The Song-Beverly Act applies to defects that first occurred during the warranty period, even if you file your claim after the warranty expires. The key question is when the defect first manifested.
