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.

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. It's like the transmission just doesn't know what gear it should be in. Infiniti needs to fix a clear design problem!

When I accelerate the vehicle doesn't speed up and sometimes it hesitates. This is dangerous especially when entering the freeway it takes a while after I accelerate for the car to get up to speed. Seems like a transmission issue. Infiniti needs a recall. I know several people with this car and have the same issue.

When you start the car stalls. And hesitates. The transmission does not downshift properly and is a serious safety hazard. I went to get in traffic and the car hesitated and almost got me hit. It appears that all over the blogs this is a common problem. They try to correct with a software update but to no avail.

Traveling on i95, minimally slippery conditions (snow), car suddenly starts hesitating/jerking. Unable to accelerate past 44-45 MPH, 2400 RPM. Had to move from the far left lane across 4 lanes shoulder. Apparently vehicle entered "failsafe" mode. Took to dealer later in the day, at which point the vehicle worked normally. Dealer (jba infiniti) said "carbon buildup." no other defects found. Charged approximately $325. One or two weeks later, the same thing happened. Problem obviously computer issue. This is dangerous, similar to gm incidents when problem occurs on high-speed roadway without warning.

The automatic transmission in the infiniti m37 sport hesitates and struggles to find the appropriate gear. Even upon soft acceleration, the transmission shifts between the first 3 gears before reaching 20mph and all between 1500-2000rpm. This can create a hazardous situation when turning left across a multi-lane, divided road--especially from a stop. The car simply won't accelerate quickly enough. Same is true when entering a highway on-ramp at speeds above 40mph. The car simply does not downshift quickly enough to provide adequate power for acceleration. For a "sport" sedan, this is unacceptable and dangerous.

While driving the car would not accelerate and the transmission was hesitating severely when pushing on the accelerator. Problem continued until the car had no power and the engine shutdown without any dashboard gauge warnings in the middle of traffic, during rush hour. I placed it in neutral prior to complete shutdown. Cut off ignition and restarted ignition and car started as normal. Tried to drive but after five minutes began to shut down again. Per the dealer defect has something to do with the fuel injection sensors. This could have been a catastrophic event.

My infiniti m37x hesitates on take off. When coming to a stop the transmission seem to be down shifting after coming to a stop. It shifts at random times throughout the driving cycle. This has been happening for a long time. I'm taking the car into the dealer this week to get the software updated. This is ridiculous infiniti. I'm hoping there's a permanent fix for this very soon.
