What owners report most
Steering
“When the steering wheel is adjusted up, down or the telescopic adjustment is used a loud pop is heard, the casing comes apart and it is no longer possible to turn the wheel left or right.”
Air bags
“The front passenger airbag warning light came on with a dash warning flashing light. I isolated the fault to the passenger seat weight sensor, which prevents the airbag from deploying when a passenger of less than 90 pounds is sensed in the front seat. The time from the onset of the warning light to discovery of the actual fault was less than a week and this was facilitated by a mechanic with a sophisticated enough OBD reader to flesh out Infiniti codes. I called my local Infiniti dealer in Tacoma, WA and they were able to supply a part number but it has been discontinued for the 2011-2013 Infiniti M37 models. Without this sensor working, the passenger airbag may not deploy in the event of a collision, and that is unsatisfactory/downright unacceptable. These cars will operate for 20 plus years and are otherwise engineered to last 200/000 miles. I have 90,000 miles on the odometer and the car is otherwise in great shape, but I may be forced to scrap it if I can't resolve the weight sensor malfunction.”
Power train
“The contact owns a 2012 Infiniti M37. The contact stated that while driving at various speeds, the vehicle hesitated upon depressing the accelerator pedal without warning. The contact also stated that while driving on an incline, the vehicle lost power upon depressing the accelerator pedal and rolled backward, forcing the contact to depress the accelerator pedal to the floorboard to maintain momentum and resume driving. Upon investigation, the contact associated the failure with the Intelligent Power Distribution Module (IPDM) relay. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 140,000.”
