Engine Defects Under the New Hampshire Lemon Law
Engine failures that qualify under New Hampshire's lemon law — stalling, overheating, excessive oil consumption — under the 3-attempt / 30-business-day presumption, with cold-weather factors.
Engine defects routinely qualify under the New Hampshire Lemon Law. Stalling, overheating, or sudden power loss substantially impairs use, value, and safety — reachable under New Hampshire’s 3-attempt / 30-business-day presumption.
Common qualifying engine defects
- Stalling — especially at speed or in traffic (a safety issue).
- Excessive oil consumption — known pattern on several platforms.
- Overheating — coolant or head-gasket failure.
- Hard starting / no-start — aggravated by extreme cold.
- Loss of power / sudden derate.
- Timing-chain failure.
- Turbocharger failure.
New Hampshire factors
- Extreme cold stresses cold-start systems and worsens oil-consumption symptoms on short trips.
- Rural and White Mountains distances expose intermittent faults and run up the out-of-service count when parts ship slowly.
- Road-salt corrosion affects engine-bay electrical and cooling components.
No one-attempt rule
New Hampshire’s presumption is the same for all defects — even dangerous engine stalling uses the 3-attempt / 30-business-day track. Stalling can still anchor a CPA theory where the manufacturer knew of the defect.
Proving the case
- Repair orders for the same engine symptom across attempts.
- Oil-consumption test results where the manufacturer runs them.
- TSBs and recalls for the engine family.
Bottom line
Engine defects that stall, overheat, or burn oil qualify under New Hampshire’s presumption, with cold weather and rural parts delays as aggravating factors. Document the recurring symptom across same-dealer visits. Get a free case review.
