2007 Buick LaCrosse Electrical System Problems

Odometer Fraud. The contact purchased a 2007 Buick Lacrosse. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. The mileage at the time of the purchase was 77,000. It was later discovered that the actual mileage was 131,000. The Carfax Report mileage was not available.

Car refuses to relearn the app sensor. Throttle body and sensor is good, always changed the EVAP Purge valve. Still throwing codes and reduce engine speed stays on..

Low beam headlights randomly turn off while driving at night and day. Causing not to be able to see the roadway at all. Very dangerous!!! They give no warning at all. Only the low beams do this. Bright lights are not affected. There was a recall for this issue but they said my car was not affected. But it is 100% affected by this recall. Ot seems like the Headlamp driver module is overheating. It gets extremely hot. This issue almost caused a very serious accident .

Taken car to dealership for computer analysis and was told that the issue was caused by P0420cataylic converter needed to be replaced. I had cataylic converter replaced elsewhere and noticed that wasn't the problem. After doing some research I found that ignition switch is the reason my car stalls while driving. There was a Product Safety Recall (14299) Ignition key rotation and replaced on 10- 8-20 but I'm having the same problem.

YOU ARE DRIVING DOWN THE ROAD AT NIGHT AND FOR NO REASON THE HEADLIGHTS GO OUT. YOU HIT THE HIGH BEAMS AND IN A FEW MINUTES THEY GO OUT. HAD THIS CAR TO THE DEALERS AT LEAST 4 TIMES AND THEY KEEP REPLACING THE RELAY AND A MONTH OR TWO LATER IT DOES THE SAME THING. WE HAVE A LOT OF DARK ROADS HERE IN OHIO AND YOU CAN BE COMING INTO A CURVE AND THE LIGHTS GO OUT. YOU CAN'T SEE A THING. GM CLAIMS THEY DON'T HAVE A PERMANENT FIX FOR THE PROBLEM.
