“I put in a new battery in my car at the dealer and it corroded again. They told me they forgot to spray it. I have had cars for 6 years and the battery never corroded.I feel there is something wrong someplace and the dealer is not being honest with me.”
NHTSA complaint #10434150, filed 2011-11, 38,000 miles“On november 19, 2007 as I was reversing out of a parking space at a restaurant, I noticed that my brakes were not working and quickly noticed a red DOT light above my fuel gauge. I had to pull my parking brake in order to avoid rolling any further. I tried several times to start my car again. Initially, several lights lit up on the dashboard and the motor seemed to respond to turning the key in the ignition. However, after each attempt, the engine cut off after a few quick seconds. After several attempts, there was no response at all to turning the key in the ignition. …”
NHTSA complaint #10209503, filed 2007-11, 3,000 miles“On occasion my Jeep will not crank. The key will turn on, dashboard lights will come on, but just will not crank. The battery has been checked and is good. After several tries it will finally crank. This occurs at no certain time of day. It sometimes has happened 3 days in a row. Other times a week will pass before it happens again.”
NHTSA complaint #10423462, filed 2011-08, 60,000 miles“The complaint is how chrysler corp. Is addressing the j30 recall. Transmission overheating causing engine fires. I own a 2008 Wrangler that cost 50k. For the j30 recall fix they are adding a hot oil icon on the dash and flash the computer to recognize a sensor. The engine can still catch fire. Someone needs to force chrysler to add a new transmission cooler to cool the fluid, and prevent the oil from boiling. I was told by the dealer engine fires can happen in city traffic starting and stopping. They also informed me that they could sell me one at $500 with two hours of labor at $110 per hr. …”

The vehicle was taken to the dealer several times but to no avail. The vehicle was not further repaired. …”
