This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Nissan propilot has a serious safety flaw. When using propilot on my 2018 Nissan Leaf sv in stop and go highway traffic, sometimes when my Nissan Leaf coasts to an almost complete stop 15 feet behind a "boxy" vehicle like a semi-truck, the Leaf suddenly accelerates like if there is no vehicle directly in front of me and if I am not completely attentive and if I do not immediately apply the breaks, the Nissan Leaf would rear end the semi-truck. This has happened to me 4 times over the past 6 months when following a semi-truck with trailer and this morning it occurred again a fifth time but this time I was behind a sedan. I have a dashcam video of the incident from this morning. I have reported this issue to Nissan but they have done nothing about it. I have taken my 2018 Nissan Leaf in to the local Nissan service center but they say there is nothing wrong with the sensors and they do not see any issues and no error codes reported by the car. I believe this is a software problem where the software ignores the radar image of the truck in front because it thinks it is an overhead sign and not another vehicle immediately in front, the camera input of the vehicle in front also appears to be ignored by the software in this situation. Additionally, I have had at least two incidents (also occurred this morning) where propilot lane keeping feature shuts off and automatic emergency breaking is also shut off and deactivated for and extended period of time for now apparent reason (in excellent weather and clear conditions, no obstructions of sensors, etc.), I have video of this as well.
The vehicle's blind spot detector turns off at low speeds potentially putting the driver at risk if the driver depends on the blind spot detector. The collision avoidance system is unreliable. When the car in front switches lanes and there is a stopped car in front the vehicle starts to slow down but releases the breaks about 50 ft from the stopped car and starts warning of impending collision. And the breaks are not applied.
Nissan Leaf with pro-Pilot assist package. Intermittently the system warning light for automatic forward emergency braking and/or lane keep assist will flash indicating system unavailable. This has occurred on multiple ovassions and at various locations. Dealer has been unable to isolate cause or effect repair. I also had this happen on a Nissan Sentra loaner car they provided so issue may be with system and not just the Leaf models
This issue occurs with the Nissan E-pedal engaged/enabled. It happens intermittently after driving off. Symptom regenerative breaking/E-brake does not engage. Vehicle coasts. No blue bars light up on the dash to indicate that regenerative breaking is active. Break pedal has be be engaged for it to stop. I have reproduced it several times usually after vehicle has been parked for a long time. Charge level between 30-80%. issue has been reported to dealer (10/23/18). Waiting for a response.
This Nissan car is equipped with features named, pro-Pilot assist (ppa), intelligent cruise control (icc) and emergency brake assist (eba). When engaged, it is supposed to keep lanes and follow distance if there is a car in front. When the car in front is stopped this car is supposed to stop as well. Ppa when engaged, if there are good road markings, will show a green stearing on the dash board, to show that car can steer it self. However if there is a car stopped in front on the same lane (ex. Stopped for a red light), this car do not detect that there is a car stopped, and keep going forward until crash into the stopped car, driver have to intevene to stop at this time to stop. I took car to dealer and they said this is normal. That is not what Nissan advertise. This behavior is quite dangerous of these cars, and my expectation is the car need to stop if there is an obstruction in the road, when the green steering wheel on dash is showing that car is doing auto-steer.
