Seven problems related to transmission failure have been reported for the 2008 Nissan Frontier. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Nissan Frontier based on all problems reported for the 2008 Frontier.
Transmission locked during driving could have caused an accident. Transmission fluid mixing with coolant causing transmission failures.
Transmission cooler in radiater failed and coolant leaked into transmission causing transmission failure and overheating. Broke down on side of road and had to be towed.
Radiator and transmission failure due to cross contamination of radiator and transmission fluid caused by cracked atf line running through engine coolant chamber in radiator.
Tl-the contact owns a 2008 Nissan Frontier. The contact stated that while driving at approximately 20 mph, the accelerator pedal was depressed but the vehicle did not accelerate. The vehicle started smoking without warning. The contact stated that the front driver's side air bag warning indicator illuminated continuously. The vehicle was towed to the contact's residence where it was diagnosed by an independent mechanic that the radiator and transmission failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 167,514. Sg.
Total transmission failure due to coolant mixed with transmission fluid.
I received a letter for a settlement offer from Nissan about the transmission cooler failure which leads to total transmission failure. I started to research what was wrong and what I can do about it seeing as my Frontier has 102,000 miles on it and is not covered by the settlement offer. As I did some research I found out about a symptom before transmission failure occurs which is at an idle you have a loss of heat until you rev the engine or start to accelerate and heat returns. I noticed that this had happened around November 2012 while I had left my truck running while parked for a few minutes which I normally do not do. I started to drive and the heat was working again so I thought it might have been a thermostat sticking and watched my vehicle for the signs of this to happen again. I did not notice anything happen again because I do not let my truck sit idle long enough until I tested it today and when I let it sit idle for a minute the heat stopped working properly and returned to normal function when I started driving it. I am trying to find a way to repair the problem before it gets worse but I do not know if I will be able to afford it. So as for the time being I will have to drive my only vehicle to work and hope the transmission does not fail completely and cause an accident or worse. Hopefully I can find a affordable repair or Nissan will be forced to repair it before someone driving down the road at highway speeds has this happen and us consumers suffer bodily injury or fatalities before they will do the honorable thing and admit their vehicle has faulty materials used in its construction and repair them. Only they will suffer in the end if they do nothing.
