BUICK Complaints

The contact owns a 2008 Buick Lucerne. The contact stated that the vehicle failed to start. The vehicle was examined by an independent mechanic, who diagnosed that the fuel pump relay and fuse had melted, and the fuse box located underneath the rear seat needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not notified of the failure. The failure mileage was 153,000.

The transmission (randomly) fails to upshift. 1st to 2nd gear. Cold or hot. Start or in morion. Transmission was last serviced at 120,000 miles.

I was traveling to school when my breaks didn’t work I tried them twice and I crashed into another vehicle. And the month or march I took it into to Buick for break issues and they said everything was fine.

On 4/24/25 I noticed a pungent odor (like rotten eggs). The odor is worse today. I did research and it appears there may be a problem and or leak with the catalytic converter. The emissions are making me and my kids feel sick, nauseous, headache, irritated eyes, etc.

Odometer Fraud. The contact purchased a 2014 Buick LaCrosse. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 92,864, and at the time of registration, it was discovered that the mileage was 84,924. Local authorities had not been contacted.

Shifter malfunction not allowing transmission to shift to park without multiple attempts. Car lurches at times while attempting to resolve problem.

Intermittent Shift to Park Message Displayed While Vehicle in Park. See #19-NA-206 (through DTC B000A may not be set!). Caused by poor design of shift position switches! This is a KNOWN issue for many GM vehicles including my 2019 Buick Sportback, for nearly 20 years. GM should be made to fix this. In addition to not being able to start car and running down battery because of car power still being on and endangering the personal safety of every person using GM vehicles, it is possible Steering Lock may or may not occur and many vehicle accessories may not operate correctly. GM needs to supply a fix.

When traveling crossing over a bridge onto a highway, my tire started to shake uncontrollably. I went to a tire shop and they found nothing. Upon traveling recently it happened again while on the highway. This issues has affected my tire pressure sensors. I was informed that this is called shudder bucking and only happens when driving at a high speed. Upon research, I was able to find out that this is a known issue for my vehicle model made between the years of 2016 and 2020. This a complete safety hazard and concern and should not come at the expense of the vehicle owner.

Electric issues, the recall for the sunroof was not disclosed and was not inspected properly…water and debris get clogged and goes into the in the engine.

While driving the information system screen that shows the speedometer, fuel center, radio, and displays go completely black and stay off for 30 seconds. They will restart and come back on. It will then stay on and then continue to flash on and off throughout driving. This poses a risk because I am not able to see any speedometer, see anything such as the distance between vehicles that show for safety and also causes me to think that car is shutting off each time it happens. There was no warning lights that pop on or any indication that it is going to happen. It just randomly does. Once it comes back on and reconnects to my phone, it will also cut off the sound every few minutes with brief pauses. All of this has happened more than one time of driving. Turning the car on and off did not help. I do have a scheduled appointment to get it into a dealer service center soon but I did see that this has happened on the 2024 model and it is now happening on the newer model too.
