What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While operating the vehicle in the driveway, it surged forward and crashed into the parking barrier in the neighbor's yard. The failure occurred without warning the failure occurred twice. A police report was not filed. The vehicle was towed to the dealer.
Driving on the highway my car suddenly lost power and has since been stuck in first or second gear after further research online it seems that a ton of Nissan/Infiniti owners both cars and suv have or had the same problem between as early as 24k-100k miles all owners I have read online has the same check engine light…
My vehicle is technically not drivable because my seatbelts are locked. I am also afraid of driving my vehicle due to the other airbags deploying on my family out of no where. There were no prior lights or warnings to this incident.
The warning lights, infotainment center and A/C were still operational. Vehicle was maneuvered off the highway , but would not start up after power down. Vehicle battery was replaced, and the same error occurred 2 weeks later while the car was idled.
The contact stated while making a left turn, the vehicle stalled. The contact stated that an unknown yellow warning light was illuminated. The contact stated that he was able to restart the vehicle and drove to his residence at 7 MPH.
The contact stated no warning light was illuminated. The contact took the vehicle to the local dealer however, the mechanic was unable to duplicate the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 40,000. The VIN was not available.
Car will stop accelerating with no warnings then will start back move when you let the sit for and hour. Engine light will not light up when the incident happened so the problem can not be diagnosed until the engine come on.
Headlamps low beams do not illuminate properly. The is absolutely no illumination above a very low horizontal plane when going down a hill or up a hill. In some cases, there is no light visible beyond 30-40 feet. This creates an extremely dangerous situation when navigation hilly roads.
