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.

Multiple incidents - stopped at corner heading uphill. Happened to touch both brake and gas pedals at the same time. I found that when going into the intersection at the change of light, no gas (propulsion) for approx. 5 seconds. Complained to service mgr. He advised he had heard this before and would contact Chrysler. Never heard from him again. Over the two years this problem occurred about 4 times. I have since been told that Nissan has also engineered this into their cars as if this makes it right.

This Jeep has remote key-less entry/engine start. The engine cannot be turned off unless the gear shift is in park. If the throttle stays open causing unintended acceleration, one cannot turn the engine off. This could result in one or more deaths and/or serious injury! if one had an accident causing the engine to rev up due to a jammed gas pedal, how do one turn it off" Chrysler customer service was contacted about this issue and their response was "the characteristic you describe, however, is a function of your vehicle's design and there is nothing that can be done to ?fix" the condition." Reference number: Email case number: Supplied upon request. In other words they don't care about this safety issue! I have another car that can have the engine turned off, but it is a standard transmission. Madza's can be turned off while in drive with automatic transmissions. This Jeep was purchased in the usa.

  • 10,900 miles
Problem developed just after 10,000 miles with mild vibration on acceleration. Problem persisted and got worse. I had vehicle checked by dealer and head mechanic at 15,000 when in for oil change. Definitely was a problem, took a day to diagnose with help from Jeep. /Chrysler said it was failure of the transfer case/drivetrain control module. It took from June 25 until August 19 to obtain new module. During that time vehicle vibration worsened further requiring backing off on acceleration and then continuing acceleration to get up to highway speed. Very much like riding on a bad washboard road plus noise coming from under front and then additional noise from rear. When going up moderate inclines back end began strongly vibrating to the point where it felt back end was going to start hopping plus a clunk noise. Backing down acceleration and then reaccelerating would lessen problem but still made vibration. Final cause after repair: Cause listed as broken propeller shaft with universal joints, replaced transfer case to rear axle; replace rear prop shaft due to carrier bearing failure causing vibration; replace final drive control module per diagnosis for shuttering in driveline. Vehicle has 17,578 miles at repair completion. Problem appears fixed in the first 500 miles I have driven since repair.
