Trunk Wiring Problems of Buick Lacrosse

For the third time, this vehicle has died at a standstill for no apparent reason. It will be performing well until parked. After a span of time, it will not restart. When key is inserted into ignition, the motor will not catch or turn over, the key will freeze or lock in the ignition in the "on" position, nothing in the vehicle can be operated - gear shift, radio/player, door locks, trunk lid, etc. , etc. Etc. The car is completely seized up. Inspection will disclose that battery, including brand new battery, is dead ( no voltage whatsoever). Only way to restart vehicle is to recharge battery. This has happened three times over span of 9 to 10 months. When battery is recharged, vehicle will operate for months until it is dead again. Something is draining the battery, but there no logical explanation; nothing such as radio, lights, etc. , is being left on. Some auto repair people believe there is a short in the car's wiring harness; others believe the defective ignition system is at fault.

Car was parked in garage for 10 hours. Found with all lights inside and out flashing. Remote entry didn't work. Car wouldn't start. Key stuck in ignition. Overhead light and wipers turned on and off on their own and were making a clicking sound. Trunk popped open on its own, then when shut wouldn't open again with the latch over license holder. Onstar didn't work and when called they couldn't "find" my vehicle for diagnostics. Called for a jump start- jumped with battery pack, started easily and ran 5 minutes then went completely dead as soon as unplugged from power supply. Would not restart. Towed to dealer who is telling me they cannot find anything wrong with my vehicle. I will not be taking this car back until it is fixed. Huge safety concern. Couldn't set parking brake or get onstar or even get key out of ignition while all lights flashed and clicked around me- seemed like an electric or wiring problem to me which can be a fire hazard and what if I'm driving down the road at 70mph and all electric goes dead- steering and all. I have e-assist and second battery doesn't help when don't have power to transfer power. I have had car only for one year brand new.

: the contact stated while driving 10 mph toward an intersection on normal road conditions, the vehicle started shaking when brakes were applied. No warning light were illuminated. The vehicle was taken to the dealership who determined the rotors must be machined. After a visual inspection the contact noticed that all four tires were of a different brand; the dealership informed there was no concern about the different tire brands. Also, the vehicle had an oil leak. The dealership determined the leak was from the oil filter and corrected it. After a few miles driven, the vehicle presented problems with the fuel pump and the dealership had to replace it. Also, an exterior lighting problem was noticed which was detected due to wiring corrosion located in the trunk. After the repairs, the engine warning light illuminated; the dealership corrected the defect but after few miles, the warning light illuminated again. The manufacturer was contacted who provided the NHTSA phone number when asked for a resolution.
