Infiniti QX30 Lemon Law

Yes. Regardless of which company manufactured the engine components, Infiniti as the vehicle manufacturer and warrantor is fully responsible under the Song-Beverly Consumer Warranty Act. Infiniti issued the factory warranty and is obligated to repair any defects, including those in the M270 engine. The origin of the parts does not relieve Infiniti of its legal obligations.

While DCT transmissions do have adaptive learning, persistent shuddering and jerking that affects drivability is not a normal adaptation period. Under the Song-Beverly Act, you are not required to accept a vehicle that does not conform to the manufacturers warranty of quality. Continue presenting the vehicle for repair and document each visit, as the dealers repeated dismissal of the problem supports your lemon law claim.

Yes. The discontinuation of the QX30 does not affect your rights under the Song-Beverly Act. Your claim is based on the warranty that was in effect when you purchased the vehicle and when the defects were reported. If a replacement vehicle is warranted, Infiniti must provide a comparable model from their current lineup or offer a full repurchase refund.

Keep all repair orders, dealer invoices, service receipts, and written communications with Infiniti or the dealership. Also maintain a personal log of each time the defect occurs, including dates, mileage, and a description of the symptoms. Under the Song-Beverly Act, your repair documentation is the foundation of your claim, so request copies of every repair order at each visit.
