AIR BAGS
1 complaint
I have an immaculately maintained 2018 Infiniti Q70L, but the OCS system began having issues at under 75k miles. Originally, the problem was the passenger seat sensor not detecting someone in the seat, so airbags were disabled. This occured sporadically for a year, but no codes were detectable by dealership. Now the airbag sensor light flashes continually, which began happening a few weeks ago. The dealership has now informed me that the OCS system has internal faults and the entire system must be replaced at a price of nearly $10K. Other years of Infiniti vehicles have already been recalled for the same issues with airbags and sensors, yet the problem persists. Message boards are full of Infiniti owners dealing with this same issue on their vehicles that are also excluded from the recall. This is a known safety issue, and a major defect in manufacturing, due to no fault of the owners of the vehicles. THIS NEEDS TO BE A RECALL.
