I have a 2006 PT Cruiser and I’m having a weird problem. While driving, the car will start chiming (like I’ve left the keys in with the door open). The warning lights on the dash (oil, airbag, etc) will start flashing, the speedometer will move around wildly and the engine will start surging. It never actually cuts off but it seems close to stalling. This will sometimes last a few seconds and sometimes several minutes. The problem is intermittent. I’ve taken the car to the dealership several times and they can find nothing wrong with it. They tell me there is no record of the malfunction. My girlfriend is the primary driver of this car. I have never seen this happen but today she called while it was happening and I could hear it over the phone. There are about 32,000 miles on the car and would like this fixed before the warranty runs out. Any ideas?
