On May 7th, I was informed the cause of load roaring noise was due to the failure of 2 front wheel bearing. After the work was completed I was informed both rear wheel bearings would need to be replaced. Four wheel bearings failed simultaneously. Yes the car is parked at the dealership and available for inspection. How was your safety or the safety of others put at risk? Potential for Accidents: Wheel Disengagement: The Buick dealership technician confirmed four wheel bearing needed to be replaced at the same time. One bad bearing would allow me the driver to possibly control the car until it is safely out of traffic. Four failed wheel bearings could cause the driver to lose all control of the vehicle and or the wheels to disengage from the vehicle which has the potential for serious injury or death. A disengaged wheel could fly off and cause harm to other drivers or pedestrians, or the driver themselves could lose control and crash. Yes, the service department at the Buick dealer confirmed four wheel bearings failed on May 7th. Yes I received another inspection from an independent auto repair servicer. No the vehicle has routine maintenance and a state inspection without any warnings of the need for four new wheel bearings.

The bolt that secures the Serpentine belt tensioner unit to the motor block has repeatedly snapped apart leaving the tensioner unit to dangle from the block. Not secured, which causes the belt to dislodge or break (both have happened) the spring is left to flail about as is the tensioner unit since it is no longer connected to the engine block. Not to say where the other half of the bolt could end up. So far each time it snaps in half the other half remains in the block. But the unit is no longer secured to the block. While driving when this occurs makes controling the vehichle unsafe. It loses power and or surges at will. A hope to make it to the side of the road without crashing or causing a crash is an issue. I cannot afford a repair establishment, a family member does my repairs. ... There has been no other inspection of the issue. As for warning lights. No. Everything is fine until the unit is jiggled away from the block after the bolt snaps in half. The force of the tensioner unit action (im assuming) is too much for the bolt - causing it to snap in two. It has occurred 2 times the second was the beginning of Feb 2025 and the first about 9 to 10 months earlier in 2024. The belt has also broken off before but the unit remained attatched to the block that time. I did see on youtube that others have had the bolt snap. Like it is not strong enough for the job it has to perform. Hope u can help

Power Steering Went out while I was on the Highway. It was all of a sudden, and I had been driving on the highway for at least 2 hours. This caused my steering to be not as controlled, and could have caused a wreck if driving by a less advance and experienced driver. The only time the warning lamp came on was the minute it happened, and when completely out. I had to drive on the highway over an icy pass for another 45 minutes. It was very difficult and stressful. It thankfully did not cause any accidents, or other damage that I am aware of.

The first time this happened the power steering service warning light came on after I started the car. I was unable to move or steer the car. After about an hour, I started the car and the light did not come on and the car could be driven. About 2 days later, the same thing happened but the light stayed on. The car was towed to the dealership and after an evaluation it was determined that the steering gear/rack and pinion assembly had to be replaced. (See the uploaded invoice from Thompson Automotive Group and photos of the parts that were replaced.) The car is a 2013 that I purchased in August 2020. The original mileage at that time was 600 miles. When the incident occurred with the power steering, the car had been driven 44,571 miles. The car was purchased from a private owner so there was no warranty, but even without a warranty this type of failure should not have occurred when the car had been driven less than 50,000 miles.
