Car engine is not accelerating and transmission seems to be stuck in a certain gear. Took it into Nissan last year and they replaced the valve body in the transmission. Now it appears it's having the same exact problem again. Very scary as I almost got into a few accidents. Also the engine is having the same low idle issues but nothing is as bad as the transmission issues. Very very very scary.
I have gone multiple times to the Nissan service department because my vehicle will randomly stop shifting gears. It will be stuck in 3rd gear and will stop accelerating. Multiple times I have been on the highway and my car would not go faster than 40mph. I video taped it and showed the mechanic but he said because it wasn't doing it when I took it they couldn't do anything. My check engine light comes on and off randomly also. My car is right out of the manufacturers warranty with 64000 miles. My driver side window is also having problems. The engine is going out. With the issues I am having with accelerating and the gears not shifting I am afraid to drive on the highway because I never know when my car is not going to accelerate.
