Lemon law eligibility depends on state law, number of repair attempts, and days out of service. Consult an attorney for actual eligibility.
The same components appear in both official NHTSA recalls and owner-filed complaints — a double-confirmed failure signal.
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.
