Buick Verano check engine light comes on

Filed Mar 29, 2026 · Electrical, Steering · NV

While driving on the highway there was a random harsh jerk on my car, and I was immediately unable to maintain safe speeds driving nearly causing a serious crash. All of the service lights (Service Parking Assist, Service Power Steering, Service StabiliTrak, and Check Engine Light) should up on the dashboard. Trying to engage the vehicle into drive after parked had a harsh jerk shifting into gear and the accelerator was not working properly (going extremely slower than applied pressure). Mobile mechanic reader coded my vehicle with U0101 “Lost Communication with TCM”. After touching that TCM connection all of the service lights randomly turned back off, and the vehicle drove (temporarily) normal. No repairs were performed due to possible recall concerns.

Back in 2018 my car was cutting out while driving on the road I had to pull out then engine light came on I was told it was rodent that ate the wires but I fact it was not because fast forward to and incident that happened Sunday last week my car won’t go inter gear and was shaking really bad and I found out it’s fruse block was bad. This power the transmission and can cause serious damage to another person on the road if it goes out while driving you lose all control of car on highway etc. this can kill anyway if they don’t correct this issue

Vehicle seems to loose power, radio & power sterring turn off and back on constantly. Shows message " Service Stability Track". I took it back to the lot where I purchased it, they had 2 different mechanics look at it and they could not figure out what is wrong with it. Picked up the vehicle a week in a half later and the vehicle was fine for a week or so and then it started up again. all power is lost on the vehicle while driving, backing up or parking at times, then it turns back on, on its own. Its like it losses power for a few seconds, steering wheel gets hard and radio turns off. Then it turns back on. Its gotten to the point to where its done it on sharp turns. This not only puts me at risk but other people. No service engine light one, gives either "service stability track" or " service power steering" or " collision sensor maintenance", but not service lights are on, no codes.

All occurrences happened on city streets and all during the daytime. First time this occurred was on 6/15/2022 with 148,467 miles. It went to the dealer. Lots of low voltage and lots of comm codes stored in a lot of modules. All were cleared out. They could not replicate the problem. Then it occurred again on 7/23, 7/24 and 7/25. Then on 7/26/2022 (twice) with 151,261 miles and again at 151,264 miles. Then 08/01/2022 at 151,475 miles four to five times. And so it goes. The car suddenly lurches like it’s downshifting. If you were to keep driving the car, the transmission does not shift. The faster you go the higher the tachometer goes. When I took it to the dealer, I had to use the highway. Could not go above 60mph. The tach reading was too high. All four door locks start unlocking and locking and they keep doing this till you shut the car off. Vehicle chimes start going off. A “Service Power Steering” message appears on the center message board. A “Service Stabili Trak” message appears on the center message board. A “Service Parking Assist” message appears on the center message board. The Malfunction Indicator Lamp icon is on. The Brake System Warning light is on. After pulling to the side of the road and you put the car in reverse, there is no backup camera picture. After shutting the car off and then restarting it, all is well until it happens again. Since the first occurrence, I’ve also noticed when using the remote control FOB, the car starts then shuts off within three seconds. But it does not do this every time.

Fuel level sensor failure. I haven't checked but I don't think a regular dealer would inspect for free because it's inside of the gas tank. The gas gauge gets stuck at around a quarter of a tank leading a sensible person to assume their is gas in the vehicle. This is a safety risk because your vehicle can stall in the middle of the road as it did in my case. You lose the ability to steer the vehicle and put other vehicles behind you or around you at risk. The problem has been reproduced by me when comparing the range for my vehicle (396 miles on a full tank) then resetting the trip after filling up. I then drove the vehicle across a couple weeks and the trip said I was at 335 miles and the range said 96 miles, which is an overestimate from the predicted range when filling up. I drove another 30 miles for work in the same day and the gas guage seemed to be in the exact same spot as it was earlier (and when I was stalled the time before) and my predicted range actually went up to 102 (pictures to prove all of this upon request.) And at 365 miles, it would be impossible fir my car to reach another 100 plus miles in range. My gas tank holds 15.6 miles and my average fuel economy was 25.5. When I filled the gas tank up after this trip, it put 14.7 gallons in which means I had .9 of a gallon. 25.5 × .9 is roughly 23 miles. Completely way off from the "predicted 100" it said before I filled up. Personal dealers have been completely unaware and I'm afraid to take it to a dealer in the event they try to charge me for it. No. No, there is no warning light and no check engine light. Gauge and light check works properly when vehicle is started and it runs the quick diagnostic by maxing out the gauges and turning on all of the dash lights.

Purchased the car used with 65k miles and everything seemed good. At around 72k the car had a loud pinging noise. I checked the oil and the dip stick was dry. I changed the oil and filter to be safe. The car has been using a quart of oil every 2000 miles. At 80k the check engine light came on. In pa that means you do not pass inspection so we had to have the engine serviced. The bill was only $212 dollars for two valve position solenoids. I did a complete oil and filter change then also. At 1712 miles later the engine light came on again, the engine oil was 1,5 quarts low again. I guess I am in the same boat as most of the others with high oil consumption, shafted by gm again. I do not understand how a company can sell something so badf and get away with it. It seems all of the gm vehicles with the 22.4 liter 4 cylinder engine have these issues. The shame is the car itself so far has been pretty good except for the oil issue. When will gm start to stand behind their product?

The system air bag notices keeps coming in the car, when you put your seat beat on it goes away. Also the oil button doesn't come on , the car constantly shakes and the check engine like keeps coming on after even being repaired. I needed a fuel pump and that's been fixed but the problem is happening again

The 2013 buick verano in question has 52k miles. At a stop light, when the gas was pushed to accelerate, the car check engine light lit and then suddenly shifted into reverse and would not come out. After trying to change the transmission setting several times, the driver turned the vehicle off, and restarted, the transmission worked at that point. The dealership indicated they have never seen this issue before. They recommended clearing codes for intake and exhaust cam solenoids by replacing them and updating software. These were done and we hope that takes care of the problem. This was a serious system failure and fortunately occurred in a location which was not as dangerous as it could have been.
