Example complaints

Brakes: “Brake fluid began leaking onto the ABS actuator circuit board and created an electrical fire. This melted the engine harness and the connector to the abs module. This was confirmed by dealership technicians at Sewell Infiniti - Dallas. Dealership informed me they could not fix the vehicle because the part needed to replace (affected by a different recall), was discontinued and made me tow the vehicle to my house. The issue was confirmed by mechanics at Parkwood collision - Frisco. …”

NHTSA complaint #11639483, filed 2025-01

Air bags: “For my 2015 infinity QX70, I was told the air bag module within the passenger seat and the occupancy classification system (ocs) which is part of the airbag system have both gone bad this friday causing my sensor light to come on. The dealer is saying the only way to repair it is to replace the entire passenger seat, which I very seldom ever have anyone in my car. Both the qx50 & qx60 have recalls for the same thing, but the QX70 does not. The light just came on friday morning, with no advance notification or issues. …”

Exterior lighting: “The interior courtesy lights under the dash remain on when car is running. During night time driving this is very distracting to attentive safe driving. According to Infiniti, this was engineeried to remain on and there is no way to turn the light off. The change to the lighting was done on models begining with 2014. In earlier models all the ambient lights go out when the car is started.”
