What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tl* the contact owns a 2011 infiniti m37. The contact stated that the hook that held the floor mat in place on the driver's side was not stable. The floor mat became loose and caused the vehicle to accelerate erroneously, resulting in a crash. A police report was filed and no injuries were sustained.
The consumer stated the air bags did not deploy during an accident, in which the repair bill was in excess of $20,000. The consumer also stated the brakes were a constant problem.
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.
The Air Bag Warning Light on the dash blinks continuously and the Front Passenger Air Bag Status Light remains on whether or not the seat is occupied. I took the car to the Infiniti dealer.
Vehicle has hesitation during acceleration, it lags and transmission is unresponsive most of the times. There are other times that the vehicles transmission will downshift and rev up while coasting down hill while foot is off accelerator. Vehicle only has 59k miles on it and should not be having this issue.
The car hestitates, jerks, revs at low speed, rough idling, and slow acceleration. I replaced the maf sensor b 4 months ago after my car engine ligth came on while on the highway and I couldnt accelerate pass 30 miles per hour.I had to pray and drive to the nearest place for them to fix it.
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.
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.
