Typical electrical symptoms owners report
- Instrument panel and dashboard gauges go completely blank while driving at highway speed, sometimes with the car losing power briefly before restarting on its own.
- Low beam headlights provide poor visibility at night, and dealer adjustments to headlight aim fail to fix the issue.
- Headlight assemblies fail due to burned-out ballasts or damaged trim, requiring full assembly replacement.
- Push-button start does not respond to the brake pedal, even after the dealer replaces the key fob battery.
- Speedometer gauge flickers on and off intermittently, and a software update does not resolve the problem.

Electrical system
General Motors LLC (GM) is recalling certain model year 2014 Buick LaCrosse vehicles manufactured April 30, 2013, to September 1, 2013. In the affected vehicles, a wiring splice in the driver's door may corrode and break, resulting in the absence of an audible chime to notify the driver if the door is opened while the key is in the ignition. Additionally, the Retained Accessory Power (RAP) module may stay active for ten minutes allowing the operation of the passenger windows, rear windows, and sunroof. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 114, "Theft Protection and Rollaway Prevention," and 118, "Power-Operated Window, Partition, and Roof Panel Systems."
Risk: Without an audible indicator, the driver may not be aware that the driver's door is open while the key is in the ignition, increasing the risk of a vehicle rollaway. If the passenger windows, rear windows, and sunroof can function when the vehicle is turned off and the driver is not in the vehicle, there is an increased risk of injury if an unsupervised occupant operates the power closures.
Remedy: GM will notify owners and dealers will inspect the driver door window motor harness, and replace the electrical splice, as necessary, free of charge. The recall began August 2014. Owners may contact Buick customer service at 1-800-521-7300. General Motors number for this recall is 14235.
