Engine Problems Lemon Law California cases are among the most common claims filed by drivers who discover their new vehicle has serious mechanical defects. If your engine keeps stalling, overheating, or triggering the check engine light despite multiple repair attempts, your vehicle may qualify as a lemon under California law.
That sinking feeling when your car repeatedly returns to the dealership is frustrating and stressful. You purchased a reliable vehicle, yet you find yourself stuck in a cycle of repairs. Fortunately, California law provides strong consumer protections when a manufacturer cannot fix a substantial defect.
What Makes an Engine Defect a Lemon?
To qualify under California Lemon Law, the defect must substantially impair the vehicle’s use, value, or safety. Engine issues almost always meet this requirement because the engine is the most critical component of your vehicle.
Examples of substantial engine defects include:
- Repeated stalling while driving
- Engine overheating
- Loss of power on highways
- Persistent oil leaks
- Check engine light that cannot be resolved
When these problems continue after repair attempts, they become more than inconveniences. They become legal issues.
Understanding the Repair Attempt Requirement
Before filing a lemon law claim, the manufacturer must be given a reasonable number of repair attempts. The California Lemon Law Presumption outlines general guidelines.
Your vehicle may be presumed a lemon if:
- The same defect has been repaired four or more times
- The vehicle has been out of service for more than 30 cumulative days
- A serious safety defect has been subject to two repair attempts
Engine failure often qualifies as a serious safety defect. Always keep detailed repair records including dates, mileage, and written descriptions of the issue.
Common Engine Problems That Qualify
Excessive Oil Consumption
Some vehicles burn oil at abnormal rates due to defective piston rings or internal engine damage. If you must frequently add oil between service visits, your engine may have a qualifying defect.
Overheating
Chronic overheating can signal a failing cooling system, cracked cylinder head, or internal damage. Driving an overheating vehicle can lead to catastrophic engine failure.
Stalling or Loss of Power
An engine that stalls unexpectedly creates serious safety risks. If this problem persists despite dealership repairs, it may qualify under California Lemon Law.
Persistent Check Engine Light
While sometimes minor, a recurring check engine light that cannot be diagnosed or repaired may indicate a defective engine system.
Your Legal Options Under California Lemon Law
If your vehicle qualifies, you are entitled to either:
- A Buyback: A refund of the purchase price including taxes and fees, minus a mileage offset
- A Replacement Vehicle: A substantially identical new vehicle
The choice between refund or replacement is yours. An experienced California Lemon Law attorney can help protect your rights and negotiate with the manufacturer.
