Example complaints

Transmission and drivetrain: “The car hestitates, jerks, revs at low speed, rough idling, and slow acceleration.

NHTSA complaint #11353083, filed 2020-09, 63,000 miles

Steering: “I'd like to report a problem that has occurred with my 2011 Infiniti M37 which seems to be pretty fatal. The plastic cover that covers the steering wheel's rod cracks open when the steering wheel is tilted to a lower position. Once the cover is cracked, steering wheel rubs on to the plastic behind it and makes the steering wheel nearly impossible to steer. If someone faced this issue by changing their steering wheel position while driving, it will surely lead to a fatal accident. …”

NHTSA complaint #11311765, filed 2020-02, 140,000 miles

Vehicle speed control: “I have several issues. The steering wheel peels. I have a cracked driver's side leather interior door. The car started jerking really bad on a city street, I couldn't go over 35 MPH. My 4was motor has gone bad! Infiniti dealership, cannot explain what would have caused the motor, to go bad. All of the car's safety features, are connected to this 4was motor. So, when that 4was light comes on, all of the safety features are turned off. This includes: intelligent cruise control, 4was, blind spot detection, lane departure, stability control, and sport mode! The cost is $8500! …”

NHTSA complaint #11206987, filed 2019-05, 190,000 miles

Engine: “I leased my Infiniti M37 sport the first month it came out in 2010 (2011 model). The first day I drove the car the issues were apparent. I drove it directly back to the dealership, they said everything was fine..its learning your driving style..(I too have had mercedes, bmw, audi etc that learn your driving style) this was not the case. Well, now I am at 33,000 miles and the issues have only gotten worse. Its been to the dealer a number of times for the jumpy stops...when breaking (normal non aggressive) the tranny wants to jump forward and almost hit the person in front of me. …”
