Hi I’m having trouble with my transmission in my car due to a safety feature that Nissan has installed on there cvt transmissions. After driving for 1 1/2 to 2 hour trips my car does not accelerate or will have a slow time gaining speed. Nissan has a high fluid temperature protection mode that basically when the transmission temp gets too high the computer cuts you off completely and intentionally stops you from going any faster. This is a serious issues if your in traffic or driving somewhere on the highway and not able to move to the side of the roadway or to a median. If my car was to completely stop in the middle of the road due to this safety feature, it could cause collisions and life threatening injuries.

3 times car has decelerated when driving on interstate for 1 to 2 hours. Last time speed dropped to 20 mph when most cars were doing 70 to 80 mph. This creates a very dangerous situation that could result in loss of life if not corrected. Nissan refuses to address the matter and problem is well documented on the internet and lawsuits. Nissan should have issued a recall covering the defective CVT. My college age grandson is driving the car as he has no other option but he is putting his life and friends at risk each time he goes on an extended trip. Nissan should at minimum replace the transmission as a safety issue but have denied our claim. Your help would be greatly appreciated.

We had a near fatal accident on the highway because the car suddenly lost speed drastically and later on a few incidents won't move up on the slope. My daughter had a hard time reaching home but somehow managed. A quick online research showed many people sharing similar issues due to faulty transmission and sensors. It seems that Nissan is simply hiding behind its 60,000 mile Warranty and not addressing and fixing this issue for the consumers and thereby putting lives at risk.

Three hours into my drive, I was going about 70 MPH and noticed my car started to slow down and was making a noise. I pulled over, got out, checked my power steering fluid. It was fine so I drove off and as I was entering the freeway, I noticed the car wasn't picking up speed again. I drove to the next exit and got off. I literally coasted to a parking lot of an industrial building. After several attempts at trying to leave the parking lot, I noticed I couldn't go up the hill. I waited about 30 minutes, picked up speed and made it up the hill and onto a 2 lane road. I drove to a hotel about 4 miles away, going about 40 MPH. I realized that as long as I didn't stop, I would be fine. The next morning I found a mechanic shop, called and drove there with minimal problems. He told me the year, make and model of my car had been having issues with the CVT transmission. He hooked a machine up and it gave him these codes: p0746, p0826, p1778 step motor, p0868. He told me to check for recalls. I was able to drive the car 3 hours back to my house in woodbridge.

Car automatically reduces speed from 65 MPH to 35 MPH while in motion on highway and will not increase speed when driving at an hour or better at 65 MPH or greater. When it autodecelerates it makes a whining noise and will not accelerate again until you turn the engine off and allow the car to sit for 30 mins or better.
