Power train

“I received a check engine light will driving which is now indicated as code P0720 and P0500. The car refused to shift past 3rd gear and began to sputter and would not allow me to go past 25mph disrupting the flow of traffic.”

The contact stated that the warning light was also present while a passenger was seated in the seat. The contact used a diagnostic scanner to identify an abnormal voltage to the passenger’s side air bag sensor. The manufacturer was contacted but no assistance was provided. The contact was informed that the VIN was not included in NHTSA Campaign Number: 16V244000 (AIR BAGS). The contact stated that the vehicle had experienced the failure listed in the recall. The vehicle was not yet repaired. The local dealer was not contacted. The failure mileage was 36,000.”
Service brakes
14 reports1 crash
“On April 2nd I took my vehicle into the dealer for recall servicing. After leaving the dealer I had my vehicle inspected the next day by a third party repair shop and my brake caliper was missing the main bolt that connects to the brake pad. Brake pads were also less than 5% wear remaining. Myself and others were put in serious danger if my brakes had failed due to this serious oversight and disregard. My suspension also was unsafe in the rear but the dealer carried out a multi point inspection stating everything passed.”
Engine

“The contact owns a 2014 Infiniti Q50. The contact stated that while driving at 45 MPH, the RPM inadvertently increased briefly before returning to normal. The check warning light was illuminated. The vehicle was taken to an independent mechanic, who determined a failure with the output speed sensor and transmission valve body. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 90,000.”
