Infiniti QX55 Lemon Law

Yes. A turbocharger failure on the KR20DDET engine at low mileage is a significant warranty defect that substantially impairs the vehicles use, value, and safety. Under the Song-Beverly Consumer Warranty Act, if Infiniti cannot permanently repair the turbo system, you are entitled to a refund or replacement vehicle. Turbo failure that leaves you stranded strengthens the safety impairment argument.

Yes. Persistent water intrusion that damages interior components and potentially compromises electrical systems is a defect that substantially impairs the use and value of your QX55. Under Song-Beverly, the manufacturer must repair such leaks under warranty. If the dealership cannot stop the leaks after a reasonable number of attempts, you may pursue a lemon law buyback or replacement.

You should allow the dealership to perform the software update, as each repair attempt including software updates counts toward your lemon law claim under the Song-Beverly Act. Document the visit and note whether the update resolves the issue. If the ProPILOT Assist continues to malfunction after the update, this failed attempt strengthens your case for a lemon law claim.

First, ensure all repair attempts are documented with written repair orders from authorized Infiniti dealerships. Then consult with a California lemon law attorney who can evaluate whether your QX55 meets the Song-Beverly Act requirements. Most lemon law attorneys offer free consultations and work on contingency because the manufacturer pays attorney fees if you prevail.
