Car has white smoke coming from the exhaust and the oil level keeps decreasing. Car stalls and takes time to accelerate P0106 code pops up from engine. There’s a rattle and whine noise coming from the engine bay. Also the gas was stuck accelerating. Had to switch the car to neutral so it does continue accelerating. After switching to neutral I was able to decrease power to the wheels and had to pull over on the road.

Jun 21, 2024

Nissan North America, Inc. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.

Remedy: Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact INFINITI's customer service at 1-800-662-6200. INFINITI's numbers for this recall are R24A5 and R24A7.

Consequence: The lack of an image in the back-up camera display increases the risk of a crash.

Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
