What 2011 Infiniti M37 owners say
Transmission & drivetrain
I was trying to accelerate from off an on ramp onto a highway and the car completely hesitated. The transmission took a good two seconds to accelerate and get into a safe position to pass, when I was struck from behind by a car in the slow lane. I have made a complaint before about this same issue and something needs to be done. I have already sent my car to the dealership and they reset the TCM, but it did nothing. Please get back to me at [redacted] or [redacted]. Thanks
Tl* the contact owns a 2011 Infiniti M37. The contact stated that the vehicle was unresponsive after the accelerator pedal was depressed and jerked while driving at lower speeds. The failure occurred without warning more than 200 times. The vehicle was taken to the dealer where the failure could not be diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 29,000.
Steering
4was and stability control warning lights stay on while driving the car. The rear of the car is very unstable, sways, jerks and steering wheel is off-center.the steering wheel is never centered and drifts in one direction with a new alignmnet. Infiniti has recommended replacing the hicas actuator. This has not resolved the problem for Infiniti owners and are then recommended to replace the 4was control box. Replacing the control box also does not resolve the issue. I have read and joined a Nissan/Infiniti forum where owners that have this exact problem have followed the recommendation from the Nissan and Infiniti dealership and still have the warning lights on. I contacted Infiniti corporate offices for further information, but was informed they do not track this type of information. …
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. This issue seems to happen to other vehicles as well according to the forum link attached: http://forums.nicoclub.com/steering-wheel-rubbing-plastic-housing-t609452.html I have tried to contact Infiniti regarding this issue and the answer I received was that there's nothing they could do since I am out of warranty. …
Speed control & acceleration
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! I purchased this car in 2011.
