Owner report 11417442 · 2021-05-17 (May 17, 2021)
I was backing out of the garage intending to stop on the driveway and inspect tires in the sunlight. The brakes had no effect and the car proceeded across the street and up the neighbor's driveway and finally stopped just short of their garage door.

Owner report 11639483 · 2025-01-29 (January 29, 2025)
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 t…
