ENGINE
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

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I’m experiencing issues that seem to align with the gcm recall despite my vehicle supposedly being fixed for this recall prior to my purchase of it. I cannot run the heat with the headlights or various combinations of things that would otherwise be normal because the battery will drain within 30 minutes, resulting in the car to going into “battery saver mode” where each system begins to power off one by one which ends with the car losing speed and just turning off and not turning back on. I’ve been stuck and had to jump it more times than I can possibly count due to it not starting or going in the battery saver mode. I’ve noticed a weird odor that smells like burning wires. I’ve owned this car for 3 years and have had these same problems with it since the day I bought it. I’m at the point now where I don’t even drive it unless absolutely necessary because I’m afraid it will shut down or cause an accident. The power steering is always first to shut down and on various occasions, I almost hit someone or something trying to steer off the road. I chose todays date as the “incident occur” date but this has been an ongoing issue since the purchase.

STEERING
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.

ENGINE
The 3.6 liter engine in my 2018 Buick Lacrosse Avenir only has 53,939 when we experienced a thermostat failure. The engine temperature was dead cold, and the dual electric fans were running non-stop. When I scanned the trouble code, I found PO128 which points to a faulty thermostat. Because the thermostat is buried under the intake manifold, we had the local Buick dealership replace it at a cost of over $800.00. I don't feel that a car with so few miles should be experiencing a thermostat failure. But this seems to be a common problem with the GM 3.6 liter motor according to a number of Buick forums that I read after the problem occurred.
