   While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code P2138, Throttle pedal position sensor switch.

   I hit a deer going 60 mph and the airbag didn’t deploy, the service airbag light came on after I hit it. I’d assume that means the airbag tried to deploy but ran into an issue

   Driver side headlamp draws moisture, keeps blowing bulbs at 104.99 a pop. Water gets in the headlight assembly and shorts out the ballast. This happens even when driving down the road at random. It could be pitch black and suddenly you have no headlights and are forced to drive with only fog lamps

   Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.

   When pulling into parking space the car rapidly accelerated on its' own and crashed into the car in the next parking space. I did not have my foot on the gas, the car was simply idling. The acceleration was so rapid that applying the brake was useless.

    The two systems that failed are the airbag release on the front passenger side and the stabilitrak system. Both systems show error lights on the dash. The front seat passenger does not have airbag protection. The stabilitrak system error light appears intermittently and when the traction system goes off the car brakes almost stop the car while driving. We go to Royal Buick in Tucson, Arizona. We worked with Germaine Kendrick. I've attached the dealer service invoice dated April 14, 2023. The invoice summarized the problem and stated that 1) a new seatbelt assesmbly is needed and 2) the service technician states that they can not replicate or repair the traction problems. Today is June 11, 2023. We are still waiting for the seatbelt assembly to "arrive". There is no solution for the traction system. We have phoned and texted 4 times. The most recent conversation on June 5th with "Chris" was interesting; Chris stated that the seatbelt part was NEVER ORDERED and furthermore, is not needed to repair the airbag warning light problem.

    Moisture has been collecting in both headlight assemblies for the past 3 years, whenever the car is outside or driven in the rain. Recently, this caused both high/low beam headlights to burn out. Replacing the bulbs is not enough, as the bulbs immediately burn out/smoke and blow out because of the water accumulation. On the driver side headlight, there was actually standing water in the headlight assembly that came pouring out when the cover was removed to replace the bulb. Dealership says both headlight assemblies must be replaced entirely to resolve the issue, due to corrosion. The vehicle has never been in an accident (there are NO cracks from collision, etc.). This appears to be a manufacturing defect or an issue with seal. This is a crazy expensive repair, to have to have the entire headlights replaced on the vehicle, on both sides, because they are not properly sealed/allow condensation and accumulation of water to take place. Can GM please cover the cost of this? Otherwise, this might be the last GM car I ever buy... This is also a major safety issue, as one must have working headlamps. Without an entirely new headlight assembly on each side, the lightbulbs, when replaced, burn out unexpectedly almost immediately, within weeks of replacement.

    After heavy rain in mid-September 2022, both headlights just stopped working. The dashboard will usually display a warning or pop up symbol that something is not working, but I had no warning and got pulled over driving at dusk with no headlights. There has been been other issues with this vehicle too! The other issues include: Bluetooth connection not working at all, the transmission has “jerking” issues while changing gears and the engine revving too high while only going 30mph while driving in suburban Massachusetts. The car has less than 70k miles, these issues should not be happening. The main issue is the headlights, considering they cost around $200/ea and just stopped working with no notice.

    MIL Lamp is illuminated and cannot be turned off or reset. The code displayed on the scanner is for P2138 "Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation." There is also a "Reduced Engine Power" message on the dashboard. Available for inspection upon request. My safety was put at risk before the vehicle was serviced because the car shut down in the middle of the street with cars behind me. I called a certified mechanic to successfully service the vehicle and he cleared the code. My safety was put at risk again after the car was serviced because the code came back on as I was driving on the highway. Car lost power and speed and as I tried to get the car pulled over with emergency lights on, I was almost hit from behind by 2 other drivers. Problem can be reproduced within 10 minutes. Per the mechanic's request, I am taking my car to a Buick Century GMC dealership on 7/16 @ 12 PM to be serviced. Warning symptoms before code came on happened especially during times of rainfall. Car hesitated to pick up speed. Overconsumption of gas resulting in decreased mileage.
