2018 Nissan Altima Engine Problems

“While driving on the highway, during the morning, my car activated the brakes on its own, this is the second time this happens the first time I took it to the dealer and asked for the sensors to be removed, and kept it for a whole day and apparently nothing was done, secondly the (front radar obstruction) is becoming annoying. …”

“The vehicle is frequently not recognizing that the brake is depressed. The brakes work fine but with the car not recognizing the brake is depressed, it will not start (as it is a push button start and the brake needs to be depressed for the car to start). Also because of it not recognizing that the brake is depressed, it occasionally will not shift out of park. Additionally because the vehicle does not recognize that the brake is depressed, the brake lights do not work which is a huge safety issue as other vehicles do not know that the car is braking. …”

“First thing in the morning the car makes a rattling noise when cold and smell of fumes coming thru car vents. Took car in Jan. 30, dealership bent heat shield. Bought car back Feb. 20 for now clicking noise was told heating shield needs to be replaced! This had to be preexisting and this car was sold to me in this condition! Now I have to pay over $1,000.00 that I don't have?!?”

“While operating my 2018 Nissan Altima on September 19, 2026, at approximately 9:20 a.m., during daytime highway traffic, the vehicle suffered a sudden and complete loss of propulsion, leaving me entirely immobilized on a highway ramp with no ability to accelerate or move out of danger. I was stranded in an extremely hazardous location with vehicles, including large commercial trucks, traveling nearby at highway speeds. I feared for my life because I had no way to move my vehicle to safety or protect myself from a potential collision. …”

“The problem of delayed acceleration. The problem occurs when the vehicle does not seem to accelerate for a short period of time. When I'm at a stop. and I depresses the pedal. The vehicle does not rev. It does not do anything for a few seconds. Even with increased force on the pedal, the vehicle does not move. The second concern is that, once it does move, it does so significantly with a jolt. This means that, after a few seconds of not functioning, the vehicle will suddenly accelerate quickly. This can create an increased risk of an accident.”
