Engine Defects Under Maryland Lemon Law

Engine defects routinely qualify under Maryland’s Lemon Law (§ 14-1502).

Common engine failure modes

• Stalling — at speed, at idle, or on startup.
• Misfires — recurring CEL, rough idle, vibration.
• Excessive oil consumption — 1 qt per 1,000 miles or worse.
• Engine knock / detonation — pre-ignition or rod knock.
• Coolant loss — head gasket failure.
• Timing chain failure — premature stretch or skip.
• Turbocharger failure — recurring boost loss.

Brand-specific engine patterns

• Hyundai / Kia Theta II — connecting-rod failure recall.
• Subaru EJ25 / FB25 / FB20 — head gasket, oil consumption.
• Audi / VW 2.0T TSI / TFSI — oil consumption, timing chain.
• GM 5.3L AFM — lifter collapse, oil consumption.
• GM 6.6L Duramax — CP4 fuel pump failure.
• Ford EcoBoost — coolant intrusion, carbon buildup.
• Ford 6.7L Power Stroke — CP4 fuel pump.
• BMW N20 / N26 — timing chain.
• Honda 1.5L Turbo — oil dilution.

Why engine defects qualify

1. Safety — stalling in traffic is dangerous.
2. Substantial impairment — engine repairs are major.
3. Value impact — engine work flags vehicle history.

Maryland climate considerations

• Hot humid summers — cooling system stress.
• Cold winters with ice storms — cold-start issues.
• Coastal salt corrosion — accelerates engine-bay component failure (Eastern Shore, Annapolis).

Bottom line

Engine defects qualify easily under Maryland’s Lemon Law.
