Twice, I was driving at a speed of 75 mph on i25 headed north. As I arrived into colorado springs, my vehicle decelerated to 30 mph in a 65 mph zone. I immediately pulled over. I waitied for about 15 min. Started my vehicle up & still it would only go 30 mph. I turned around & headed back for pueblo. Unsure & afraid that my vehicle would not make it home. Once my car was sitting for an hour, the transmission allowed the speed to rise above 30 mph. The same incident occurred on 6/27/2015. I am afraid to drive my vehicile out of town, in fear of getting stranded, the car overheating & the mechanical transmission malfunctioning. The Nissan dealer in order to resolve the problem, needs to install a "transmission cooling system". I purchased the extended warranty thru 1st extended, over $2600. 00. They refuse to honor the warranty, claiming the cooler was ot in the car to begin with. I spoke with Nissan & southwest motors (where I purchased the car around 1 1/2 yrs. Ago. They've both confirmed that this exact problem has occurred in many Nissan vehicles. If the warranter is unwilling to warrant the problem, which is a major mechanical malfunction, then my 2012 Nissan Altima needs to be recalled! please help me for I fear this problem is a safety hazard driving on the hwy at a reduced speed & becoming stranded.
