Vehicle Speed Control Problems of Nissan Leaf - part 2

Car accelerates on it own this afternoon in both forward and reverse. Had to constantly use brakes to control it to bring it back to the driveway. This occurred from a parking position on a public street as soon as the car was put into the driving modes (both forward and reverse).

The contact owns a 2013 Nissan Leaf. While driving 20 mph, the vehicle independently accelerated. The contact then coasted over to the emergency lane and observed the floormats were not the cause of the failure and there were no warning lights illuminated. The vehicle was towed to the dealer who stated that there were three brake codes present. The contact was uncertain of the diagnostic results. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 12,670.

My 2015 Leaf s is 3 weeks old with less than 700 miles. I was descending an 8% grade hill in b mode with a sharp bend at the bottom. As I went to apply the brakes, the pedal went to the floor and b mode cut out. The car was now rolling down the hill and accelerating under gravity with no brakes and without b mode slowing the car. I was expecting to hit a brick wall at the bottom of the hill when suddenly, after no more than two seconds, the brakes and b mode came back on and I safely stopped. On reflection after the incident, it was as if the whole computer/electronics momentarily shut down and then rebooted. I didn't notice if the dash lights went off or not.

Brake system failed and ignition started and thrusted car forward. It seemed like the brake got soft and then would not function. This incident caused the car to damage private property and caused major damage to front end of the vehicle.

Two months ago I was braking moderately when the car shuttered, there was a bump and the car began coasting. I saw that it had popped into n (neutral) even though I didn't touch the gear shift. I tried to put it back into d (drive) but it wouldn't respond. I pushed the car to the side of the road and tried several times to shut it down. Finally, it responded, then restarted and drove normally. After that, there would be intermittent shuttering and bumping while braking. The recharging lights will pulse and I can feel the regenerative feature grab and then release. One morning recently, along with these symptoms the range plummeted quickly, by about 1 mile per second. After driving only 20 miles I had 17 miles of indicated range. Then, yesterday, the first problem reappeared: the car went into neutral and briefly wouldn't respond. The car is now at the dealer.

Driver and driver's young child were in vehicle. The driver was approaching an intersection and slightly increased speed to cross intersection. Accelerator pedal dropped to the floor, resulting in sharp acceleration at full power towards the next intersection. The next intersection contained other vehicles and a railroad crossing, and displayed a red traffic light signal against the vehicle's direction of travel. The driver pressed brakes and was able to slow the vehicle, but the vehicle accelerated sharply again when the brakes were released. The driver pressed brakes again and pulled the emergency brake switch to slow the vehicle again. The driver then pushed the park button located on the shifter and the vehicle jerked to a stop. The driver then looked at the accelerator pedal and saw that the accelerator pedal was not physically stuck. The driver was able to force the accelerator pedal to pop back up to its normal position by using driver's hand. The local dealership was unable to duplicate the incident, stated that "no codes were stored, no visible damage to accelerator pedal, vehicle inspected by Nissan dts. . . And found no problems with vehicle at this time. " Nissan states that no repair was necessary because Nissan was unable to duplicate the problem after 11 miles of testing. Nissan has refused to accept return of the vehicle at this time.

I have run into what I believe is a small design flaw. Scenario: 1) Leaf is parked in condo parking garage with gentle uphill slope on parking space. 2) startup sound is turned off. 2) forget the Leaf is still plugged in to av l2 evse. 3) put foot on brake, push start button. 4) shift into reverse, not looking at dash screen to see warning that Leaf won't start. 5) press down on parking brake lever to disengage parking brake. 6) press accelerator. Result: the Leaf doesn't start since it is still plugged in to evse. The Leaf shifts out of park into neutral after step #4. Once parking brake is off and foot is on accelerator, there is nothing to keep the Leaf from rolling back. If it rolls far enough it will damage either the l2 connector to the car or the evse or both. Comment: this is not a hypothetical, it has happened to me 3-4 times in the last year. Fortunately, I quickly realized the Leaf was still connected to the evse and applied the brake so that no damage was done. In my opinion, you should not be able to shift the Leaf out of park or release the parking brake while the Leaf is still plugged in. I would suggest changing the software to avoid potential damage to the Leaf l2 connecter, evse or damage to property in the vicinity.
