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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2012 Grand Cherokee hasn’t seen the same complaint volume as the 2011, at least not yet.

It’s worth noting both model years are part of a class-action lawsuit that focuses on a defective TIPM and a long wait for replacement parts.

The 2012 also received national attention after it failed a Sweedish Magazine’s “moose test”. the test measures a vehicle’s ability to swerve out of the way of an obstacle you wouldn’t want to hit while driving down the road … like a moose.

2012 Jeep Grand Cherokee Owner Comments

problem #1

Jun 282012

Grand Cherokee 6-cyl

  • 36,700 miles


Engine started running roughly and attempted to stall in traffic. Check engine light came on. I went to Jeep dealer in gulf shores Alabama and was told that the left cylinder head was defective. I was also advised that it was a manufacturing defect that could result in catastrophic engine failure. It is a well known defect in the 2012 Cherokee with the 3.6 pentastar engine. If this vehicle had stalled while on an interstate ramp, or a valve in the defective head dropped down into the cylinder, an accident could result. Jeep has full knowledge of this defect but has not issued a recall. This could be as serious as the GM ignition switch issue.
