2018 Nissan Leaf

The contact owns a 2018 Nissan Leaf. The contact stated that while parking the vehicle at low speeds, the vehicle suddenly accelerated on its own. As a result, the vehicle jumped the wheel stop, coming to a complete stop after colliding with a tree. The air bags did not deploy. A police report was filed, and no injuries were reported. No warning lights were illuminated. The vehicle was taken to the dealer, who did not provide a specific diagnosis but advised the contact that a BCM reprogramming was required. The vehicle was repaired. After investigating the failure, the contact related it to NHTSA Campaign Number: 23V494000 (Vehicle Speed Control), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 12,300.

Hello NHTSA: I purchased a 2018 Nissan Leaf from Carvana on December 29, 2022. Within a short period of time the car experienced seat belt and air bag warning lights. The car was repaired under factory warranty by HGreg Nissan in Cutler Bay Florida but continued to display warning lights. The satellite communications system was not able to be repaired. This failure deactivated certain convenience and safety features. On March 16, 2023 a warning message and display indicated there was a high voltage battery malfunction and the car needed to be repaired by the dealer, On March 20, 2023 the car was taken to the dealer. The dealer informed me that the car was unsafe to drive and would not, nor did they ever, return the car to me [with the exception of a one-week test drive that did not correct the reported issues]. On August 3, 2023 Nissan North America declared in writing that the car was a Lemon under Florida law. Nissan refunded the purchase price of the car. Both Carvana and Nissan North America have refused to fully compensate me for certain incidental expenses including auto insurance [required to kept active until title transfer] and unused monthly prepaid Carvana maintenance costs. These fees were assessed from March 20, 2023 until August of 2023. During a discussion with Nissan North America their agent disclosed that they intended to wholesale this car. My immediate concern is that a Lemon-declared car should be disclosed if it is even allowed to be resold.

The malfunction warning light came on to indicate that the automatic braking system was not working. I brought the car to the dealership, which quoted me $1900 for a new sensor. I have read about accidents and near collisions due to the malfunctioning of this system and am now worried that there might be sudden braking that others have experienced. I would like to get this system fixed, but do not believe consumes should need to pay $2000 to repair a defective system.

On may 12, I was in a long line of cars at a red light , stopped. all of a sudden my car started moving and accelerating toward the car in front of me. When I got over the initial shock, I started stamping on the brake (2-3x) and nothing happened. I clipped the other car as I yanked the car out of line into the turn lane. I turned off the car and shook. Then I handled the insurance stuff with the other guy. I did NOT take my foot off the brake. (I reported this incident to the NTSB, BTW.) I wanted the collision center and Nissan to look at the black box, but the garage didn't and Nissan said that was no black box.

I was stopped at a light, in a long line of cars, my foot on the brake, a few feet away from the car in front of me, and the same in back. All of a sudden, the car started moving, accelerating, jerking forward. I was shocked, pushed down on the brake, nothing happened. starting pulling the car out of line because I was going to hit the car in front of me. I was pumping the brake, and NOTHING HAPPENED. Clipped the car in front's rear left bumper, wrecked my front right bumper. Finally pulled into the turn lane and finally the brakes caught. It was like someone had taken a gizmo and turned on my car (like the OnStar mess a few years ago.). Nothing like this has ever happened to me, in any car, including this one, until 5/12 at 2:00 pm. It was terrifying.

The contact owns a 2018 Nissan Leaf. The contact stated that while driving approximately 60-65 MPH uphill, the vehicle went into protective safe mode due to a faulty signal, and would no longer exceed 20-25 MPH. The vehicle was taken to the dealer, who informed the contact that it was a known failure that occurred in cold weather. The contact stated that the failure reoccurred several times. The vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 38,225.

The PTC Heater and A/C compressor failed on my 2018 Nissan Leaf, just as the winter of 2022 was getting started. The vehicle passed prior service inspections, with no mention of issues on either of these components. The failure of the PTC heater and A/C compressor results in a "Service EV System" error message, and indication that the vehicle would not restart after powering off. When this error message appeared, the heating and defrost capabilities of the vehicle were lost. The fans would continue to blow air, but windows would fog up. I could not charge my vehicle in this error state either, so if I hadn't been close to home, I would've been in a potentially dangerous situation because it was cold out. The local Nissan dealership confirmed the error codes of P0AA6-1A (HV battery voltage system isolation) and P31E7 (restart inhibition) were present. They initially fixed this issue after nearly 5 months of the vehicle being in their shop. These codes, paired with the information I've read on the Internet, indicates others have had this issue before, and the normal repair involved replacing the traction battery (400v high-voltage battery), not these two components. The "Service EV System" came back less than 36 hours after paying for the repair. The 12v battery was also at a low voltage, which may have been related to the vehicle sitting for so long for service without being charged.

Around 45 degree weather, while driving on the freeway, my electric battery mileage started to fluctuate erratically (73% to 8% to 14% back to 70% and finally to 60%). It gave me low battery warnings two separate times. At the same time this happened, a warning light indicating the AEB had been turned off started flashing on my dashboard without any collision, jerky movements, sudden stops, or changes to settings. This is extremely concerning because of the car immediately brakes or if the battery dies on the freeway, it could cause a major collision.
