Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2012 Nissan Frontier Owner Comments

problem #1

Jan 072013

Frontier SV 4x4 4.0L

  • Automatic transmission
  • 7,000 miles


Hello fellow Frontier owner's. My 2012 Nissan had no heat. No leaks detected by Dealer or myself. Dealer topped off coolant reservoir and said keep eye on coolant level. Four day's later, no heat. Back to Dealer. Coolant low again. No leaks found, again. COOLANT'S GOING SOMEWHERE!!! Saw problem's with later model Frontiers on this web site. Asked if leaking into transmission or bad head gasket. Dealer finally ckecked eng. oil. Found my missing coolant! Dealer contacted Nissan who said they have had problems with POROUS engine blocks. WHAT!!!! My year old Nissan with 7000 miles needs a new ENGINE! Will take 3 days to repair when new engine block comes in. But it's OK to drive till then.....hmmmm. WTF Nissan! Where's the quality. VERY disappointed. Considering going back to American made...

Update from Jan 26, 2013: Dealer had my 2012 Frontier for 1 week. New engine installed. Seems to be running OK. Must say, I was treated very well by my Dealer, after all it wasn't their fault. Service Manager did tell me that Nissan told him 25-30 Frontier's had been sold with this problem before being caught by Nissan. So, 2012 Frontier owner's be aware. I can only hope my bad gas milage was caused by bad engine. Fingers crossed! I'm still wondering, if Nissan knew these bad engine's were out there, didn't they know what vehicle's they were in, and who they had been sold to? Maybe there was money involved....Oh well...
