Jan 29, 2025Electrical systemBrakesFire

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. InfinitiUSA customer service acknowledged the issue and that they would have the original supplier of the engine harness (discontinued) make me one if I purchased at the dealership (which to my understanding would not solve the original issue at hand). It is available to inspect upon request. I have pictures and videos. The fire did put myself and others at risk as the engine harness was melting and shorting out while pulling my vehicle to the side of the road. It has not been inspected by insurance rep; at this time. There were zero issues with the vehicle or modifications to vehicle at the time of the incident. There were no warning lamps or symptoms until it was too late.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Infiniti QX70 verdict →
