On 8/2542018 I was driving my 2005 Nissan Xterra down a highway in the suburbs of phoenix, az and when driving the vehicle abruptly began to jerk and go out of gear and would not accelerate. There was no warning on my dash that would tell me there was an issue and I had to wait in the car for approximately 2 hours in the 105 degree heat for a tow truck without water. I had the car towed to my mechanic and was told that the transmission fluid had been mixing with my coolant which was a common problem with the design of that year and Nissan tried to wipe this under the rug. I am in need of an entire new transmission and my car has 82k miles on it and is now 13 years old. Nissan agreed to pay for the cost for a period of time but if a recall had been issued, this problem could have been fixed for under "$150. I would greatly appreciate your assistance in helping me recover the damages that should be paid for by Nissan as they were aware of this problem and did nothing to assist me .
Nissan is well-aware of a design flaw that allows radiator fluid to cross-contaminate transmission fluid. They jokingly (at least their dealers) refer to it as a "strawberry milkshake". The antifreeze degrades transmission parts and causes transmission failure. A quick web search shows over 300 such cases.
