Notes: The 2005-2007 Xterra appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

The same defect exists in the Pathfinder & Frontier as well. And according to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

2005 Nissan Xterra Owner Comments

problem #1

Sep 162012

Xterra 6-cyl

  • 100,000 miles


Our daughter was driving home, late at night, when the engine began making strange sounds and lurching at about 50 mph. She was only a few blocks from home, so drove home very slowly. On later inspection, my husband found the radiator/transmission issue and looked on the internet to see if others had this problem. We were horrified to discover that many, many, many Nissan owners have the same exact problem of coolant in the transmission. (our Xterra has just over 100,000 miles.) this is obviously a well known issue with Nissan, but nothing has been done. We spoke with a regional manager with Nissan who listened politely, said she'd look into it, and had her assistant finally call us over a week later (she promised four days) to say nothing could be done. Something can be done! I encourage anyone with this same problem to write to Nissan, send a cc to your better business bureau, and submit complaints to consumer awareness groups to document this problem and get Nissan to act responsibly for their faulty radiator. This is a major, costly, potentially dangerous issue that should never have occurred in the first place. We love our Xterra, faithfully change the oil, and have recommended it to so many other people. It feels like a slap in the face that Nissan will not admit their role in this problem and do something about it! updated IVOQ 11/19/12
