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.

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.

Front headlamp burned out due to moisture in the assembly. There is an issue with the ballast in the headlamp assembly for the turbo model. The seal may be faulty due to the headlamp shorting out except for the daytime running lights. I realized that it had malfunctioned and there was moisture in the assembly itself. My repair shop quoted $1500 for the repair/replacement as the whole assebly needs to be replaced. This is definitely a safety hazard and a common one for this make and model. This should be a recall due to the faulty headlamp assembly.

Called local dealership for a few recalls, they said they had to order the parts for recalls so when they got the parts they called and set me a time to get them fixed well when I got there they said that it only had 1 recall and they had to order the part that was already supposed to have been ordered to began with and they would call when they get the part in "still waiting on that call" the vehicle has 97000 miles and is also burning oil fast and smoking out the exhaust, they said it was out of warranty and there is no recall on the engine oil consumption on this vehicle because its VIN specific so the bill would be on me to have the engine tore down to see what is causing it to burn oil but I no it's because of premature wear of the piston rings after the research I have done on these engines so far but what ever the case they have yet to call me back and it's been almost 2 months now not sure what to do at this point.

My car has been blowing light bulbs very frequently. I noticed that the wire what is chard and burned and naked resulting in the wires touching each other and causing my lights to fail. I replace the wiring harness once and two months later the insulation was burnt off of the wire again. There has been 2 instances where ive been driving and my headlights have went completely out at night time and I live in a rural area where there's not a lot of street lights. It almost caused me to wreck. It's not just my vehicle that has this issue. I have three friends who either drive a Regal themselves or have a close family member that has one and all three of them have told me that they're experiencing the same issues. This is definitely a safety concern. And if it were to happen to somebody else who was maybe not so lucky it could have caused a fatal accident.

Whenever I am driving my vehicle for an hour it starts to stall or sputter in traffic and the engine dies completely. It will restart but still continues to hesitate when accelerating. I've taken it to a mechanic and no error codes pop up when this happens so they do not know the cause or how to fix the issue.

When I try to use my seat warmer on both the passenger and driver side it stays on for a few seconds and then turns off. The driver side has been like this for a couple of years. The passenger side just started about a month ago. My seat warmers come on but never get warm and they cut off after only a few seconds.
