2015 Nissan Altima fuel/propulsion system problems

“The transmission failed in my 2015 Nissan Altima. The check engine light is currently on due to a defective transmission. While I understand that Nissan extended the transmission warranty by two years or 24,000 miles following a class action lawsuit, I find this coverage completely unreasonable, insufficient and irresponsible, and most importantly unsafe. My vehicle has only 83,800 miles and has been well-maintained, yet the transmission still failed. While driving in the freeway in San Diego, the vehicle suddenly lost complete transmission engagement and power. My vehicle was almost rear ended by multiple cars. The check engine light appeared after the transmission failure. A Nissan dealer later confirmed the vehicle needs a new transmission. Nissan and NHTSA should have done a complete recall after the class action lawsuit against Nissan for putting faulty transmission on Altimas 2015.”

“While driving down the interstate at 70 miles per hour, going up an incline, the car lost ALL power & then jerked kicking back into gear. Once off the interstate attempting to get to a safe place, it completely shut off without warning! No check engine lights or any warning lights. Just randomly shuts off. After replacing what was assumed as the mass flow air sensor ($186.00) & the crankshaft sensor ($80) it continues to have issues. The battery (new battery $220) was also replaced & the alternator checked due to randomly shutting off-which checked out to be fine. Come to find out it’s the CVT judder. After reading all the complaints, I’m confused as to why there isn’t a recall or extended warranty on the transmission. My car only has 119k miles! We should not be having issues with these transmission.”

“I was using cruise control on the highway. My RPMs started going up and down and my speed slowed. I took it off cruise control and the speed was irregular. The car responded slowly to my pressing the accelerator. My car started squealing and I pulled over on the turnpike. I tried to press the accelerator after I stopped but the car would not move. I was unsafe because my car was on the shoulder of a highway and it was 85 degrees. I was also unsafe because my speed was not consistent and there was traffic around me. Lastly, I had to wait an hour for a tow truck. Two mechanics confirmed that this is a CVT judder problem. There were no warning lamps and no signs of a problem before this occurred.”

“At less than 68,000 miles, the timing chain started to fail. There were oil leaks reported over 6,000 miles before but dealer said it was due to the oil change, but we now know it was the valve cover gasket. Losing power due to engine failure would be unsafe given power steering gone etc...”

“On my 3rd transmission since March 2021 1st one was April 2nd one was June Then car was in shop for over 2 months drive it for 1 week 3 transmission was put in November so yeah this car is bad also corp wont help not even anything after a manager called me a crazy [XXX]”

“I was on the highway and my car would not accelerate at all, during up hill or flat portions of the highway . This was was super scary because I’m on the highway in Pennsylvania so there’s semi’s flying by. So I pulled off an exit turned the car off waited, unplugged the battery and after a few mins I plugged the battery in and started the car. This did not work at all, so I took a backroad home, later on the car started working correctly. I made an appointment to get the car looked at (thank goodness for extended warranties) but it happened again while I was getting on the highway, I almost got hit by a semi hauling a reefer, almost peeled myself swerved into the side of the highway. Cause a ton of traffic, cuz I could not get home any other way, so I took it in that same day freaking out cuz I almost died. The said it was a bad O2 sensor and that it was covered under the warranty. So they fixed it and everything was fine until last year I got sideswiped by this old lady in a old af Hyundai suv. And she literally took my entire front fascia so my insurance covered all the repairs and the rental I needed but once they gave it back I noticed the car was…”
