Today is 8. 26. 2025, I took this car back and left it w/dealership: let them figure it out! I told them 0ne month after purchase this car is constantly empty with no/oil. I should not be getting oil changes this often. "OH, it just burns more oil and you bought a used car". . . Months later I hear smalls sounds, engine light comes on, then goes away, smoke begans to continue spreading behind the bumper building a permanent black spot on bumper! it smells, from time to time, plus car feels sluggish when driving past 50mph almost scared it will cut off** now, I gather my funds that I don't have to spend (cash) no creditcard and I proceed to belle tire! I am on file within their system. (receipts) they do what they do. . . Apparently no leaks. But the car is burning too much oil!! too fast! "keep an eye on your levels". . . Hmmm* I also got a maintenance tune-up on my next visit. So far roughly $2000 has been spent towards this vehicle (Buick). (new battery also) plus aaa cost *I have a membership* now time continues to move forward this car knocking,clouds of smoke, in the car, outside the car, around the car, thru the vents, pulling, stahling, knocking, clunck,clunck,; embarassing!!! my son and I, OH no. . . The meat inside a barbecue grill* drop off/ASAP (pulled over called aaa). (7/24/2024 - 8/25/2025)owned this car 1yr!! I need a new car they wont give me one. . . I made every monthly payment on time all by western union (receipts). I go into the same store each month 19th -22nd and pay. They don't want to trade-in either*.
Well the belt tensioner and the hybrid motor drive motor performance and hybrid power train control module requested mil illumination yes not just any mechanic can work on the car because of the hybrid system is to much voltage and the check engine light came on the car.
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.
Stalls when going up hill or if I stop at stop light and then try to proceed it jerk and go fast and also the display goes out and restart.
The "auto stop" on my car, when I was at stoplights or stop signs, would not automatically restart. The engine failed to start again when stopped in "idle". .

Constantly been having engine problems. Engine light coming on and off. I was driving it down a highway, coming to a stop due to a red light when the whole front of my car begin to sputter and gave out. It read "stabiltrak" but when taken to the shop it only read a code for the carbon filter. Which, was changed and did fixed the problem for the time being. However, its doing the same thing again. . Which is very dissapointing because its a very well kept up with car, never goes without its necessities. . And at this point I'm thinking it could be my braking system due to this problem weakening my brakes but I don't see why because those were changed about 6 months ago. Maybe, even an electrical problem with my traction control.

Service stabilitrack comes on and reduces engine power. Happened this morning driving on the freeway almost caused a huge wreck because I had nowhere to go and couldn't go the freeway speed.
When the car had mileage in the mid-upper 30,000 in 2018, we noticed that as the speed coasted down to 30mph, there was a hard downshift. So hard, you thought the engine fell out of the car. At the time we had not realized it only did this when the engine was cold. So, when we took it to the dealer, they could not replicate the issue. In 12/2019, we left it overnite and they "did" replicate the issue the next morning. This is stated on our service bill. They suggested a deep atm flush, even though we had a normal flush 18 months earlier with them. We paid them to do it and the problem persists. Since we slow down every time we approach a stop sign or stoplight, this occurs as we get down to 30mph. Exactly at 30mph!!! once the engine is warm it, we do not notice the issue. But we live in northern ohio & the nites are cold oct-April. We drove the car to warm miami FL in 1/2020. It still did it, but only a mild downshift then quickly did not repeat as the temp was warmer there. To reduce the hardness of the downshift, we have reverted to trying to let the car warm up after starting it and applying the brakes as we slow down to 30mph! it is sad that this has to be done, as we have been taking great care of the car & it only has 48,000 miles. And we are not moving to FL!!! we bought the car new from this dealer.
