“When going over speed bumps my vehicle stalls. This is the third time this has happened in the last 2 months. I've brought it to the dealership multiple times. Each time I've been told there is no problem, or that I need spark plugs replaced, or the throttle body needs to be cleaned....nothing has helped!”
NHTSA complaint #10456085, filed 2012-04, 29,300 miles“I received a recall letter back in the summer 2014 for faulty ignition switch. Called dealer, parts not available. Called several more times since, still no parts and told to wait for letter. Well, it is now feb. 2015 and still no parts/letter. It states that ignition switch can turn from start to run, which will shut down engine or other electrical parts ( steering, engine, power brakes ) increasing the risk of crash. Do I have to wait till I crash before this is taken care of ?”

The radio went out, the odometer and temp/compass went blank, and I lost the power steering. Luckily I was able to steer it over to the side. I then turned it off and back on and there didn't seem to be any problems. I drove it another hour and half home and didn't have any other issues. …”
NHTSA complaint #10246856, filed 2008-10, 17,250 miles“While sitting at a stoplight, on two (2) occasions my 2008 Jeep Grand Cherokee 4x4 suddenly accelerated on its own while my foot was on the brake and revved up (throttle surge), then the tach went back to normal, and the engine went back to idling. Took it to the dealer I bought it from, they checked the on-board computer and no incident showed; they told me they called chrysler but no one has reported this before and no technical bulletin has been issued regarding throttle surge issues. Have only had the vehicle 11 months. …”
