Notes: Radiators are still cracking, leaking coolant and destroying transmissions. Which is a shame when you consider that otherwise, this would be a great small pickup truck.

I have a 2006 Nissan Frontier. While driving down the road the truck shudders and shakes and cannot shift into gear. I had no pick up while driving on the interstate and had cars speeding by me at 75mph while I was barely able to drive the truck. The truck would drive fine and than this would happen out of nowhere. I took it to aamco and found out I had water in the transmission due to a leak in the radiator. I had to pay $2500 to have my transmission rebuilt and a new radiator installed. I feel this should be a recall on Nissan part because it was a faulty radiator that caused the problem and could have caused a severe accident. I have heard of alot of complaints regarding this same problem but Nissan refuses to due a recall. I have the same fuel gauge problem that was just recalled and I ran out of gas because of it. I feel that this needs to be investigated before someone is killed in an accident because their transmission just stops working while driving on the interstate.

Purchased a used 2006 Nissan Frontier 9/18/09 from fresno Acura. Approx 2 weeks later I drop it back off at the dealership, due to the heater not working & a shudder in the transmission. Findings radiator/transmission oil cooler ruptured and fluid leaked into transmission & vice versa, I found out that transmission fluid was going into radiator. Dealership would not honor transmission warranty due to the radiator not being under warranty and transmission contamination was effected by radiator. This is so wrong, unjust and corrupt. Possible damage ranges from $3000-$6000. A consumer should not be responsible to pay this for this kind of damage that was affected by a defective part that should of been recalled or corrected. A person pays approx $23,000 for a new vehicle and should not have to dish out another 3 -4 thousand dollars on a 3 yr old vehicle. This is bad business and will give the Nissan a very bad reputation.
