Work/repair orders, available on request. It appears to be a common issue with Nissan Altima's featuring the ctv transmission. 1) purchased the car from hertz, 12/13. 2) acceleration problem noted when first extended trip was taken to bakersfield in 5/14. 3) problem: when the engine was warm the transmission sensor fails and car can not accelerate. Car failed going over the "grapevine" in gorman, CA. 4) under Nissan 60m warranty, took the car to get checked. Car had 59m miles on it. Explained the problem. They claimed it was a throttle sensor. Fixed it under warranty. 5) next trip to las vegas, going up the I-15 through victorville, Aug/2014. The exact same problem occurred. Acceleration failed when engine was warm and climbing a gradual incline. 6) took the car back to bp Nissan. Now they claim to know for sure the problem was not with the throttle sensor but with the ctv transmission. Unfortunately they now claim my car is no longer under warranty and requires a $4,000. 00 new transmission. 7) after researching the problem it appears this is a common problem for the new Altima ctv transmission. They new what the problem was when I first brought the car in with 59m miles on it. They "kicked the can down the road" hoping I wouldn't come back until after the 60m mile warranty expired. Dangerous situation having to pull to the side of the freeway. Especially with kids in the car. They refuse to give me a "decline of service" letter. Please advise. Regards, tom timmons.
