What 2017 Infiniti QX50 owners say
Air bags
The contact owns a 2017 Infiniti QX50. The contact stated that while driving at an undisclosed speed, the passenger's side air bag sensor unexpectedly illuminated and failed to turn off. The vehicle was taken to the dealer, where it was diagnosed, and determined that the passenger's side seat cushion had failed and needed to be replaced. The vehicle was repaired. The vehicle was later taken to an independent mechanic, who provided the same diagnosis and informed the contact that the passenger's seat cushion needed to be replaced. The vehicle was repaired. The contact expressed concerns regarding the significant price difference between the dealer's repair cost and the estimate from the independent mechanic. The contact's spouse was concerned that the failure made the vehicle hazardous to drive. The manufacturer was made aware of the failure. The approximate failure mileage was 89,000.
Airbag light came on. Diagnosed by Infinity as code B00AO-02 which requires replacing the Passenger Front Seat Bottom Assembly at the cost estimate of $9871.82 (date of estimate is 1/27/23) according to Infinity. Ethos extended warranty will not cover the issue as well as Infinity. Interesting info: Ethos did cover did not cover this particular make/model. However, after Infinity changed manufacture for above said problem, Ethos now covers the SRS problem described above in their extended warranty. This leads me to the suspicion that 'maybe' Infinity was aware of the problem since they changed manufacturer. THIS IS A CRITICAL SAFETY ISSUE! Mileage on the vehicle on 1/27/23 was 9,665 miles. This car is immaculate, never wrecked always garage kept, driven my 86 year old widow. The car is a so called 'high end' luxury vehicle with a sub-par SRS system.
