“My 2003 Jeep grand cherokee Laredo started experiencing starting problems. I would get in the car and try to start it and it would be dead. This doesn't happen first thing in the morning. I can drive the car 5 miles, get out for 5 minutes, and when I start it again, it's dead. Usually I have to wait about 10 minutes. If I try to start it while I'm waiting, the gauges all go crazy, the radio goes to 12:00, and it won't start. Sometimes it cranks but doesn't turn over. When it does turn over, I have to keep my foot on the gas or else it dies on me. …”
