2016 Buick Verano electrical problems

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.

The side detection system got corroded as it was exposed to water. My airbags, turn signals, speedometer, cameras, blind spot warnings, etc. went out. This costed almost $2k to replace and get fixed when this could have been avoided if the side detection parts weren't easily exposed to water. Knowing that this could happen again as this is the way the car was manufactured does not sit well with me. It started failing while on an interstate which caused very unsafe driving conditions for me and the drivers around me. This seems to be a common issue with the Buick Verano that has not been addressed in a recall. The warning lights came on as soon as the failure started occurring.

- The side detection module became corroded, blew a fuse and stopped functioning. This was reported in a service bulletin and extended warranty protection for some GM vehicles, but not the Buick Verano. [XXX] - This happened while driving. The vehicle would still drive, but lost all gauge functions (No speedometer, tachometer, fuel, or temp gauges). -The side obstacle detection system does not work. -The system also interferes with the passenger side airbag and leaves it turned OFF with a passenger in the seat. These obviously all create a serious safety risk and have not been covered by a recall for this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Power Steering, Brakes, Turn Signals, Monitor Screen. The Cars steering will lock up and pull to the right hand side and the brakes get mushy. This could be deadly to myself and other motor vehicles. It happens suddenly with out warning and if there is a vehicle in the right hand lane, you will crash into it. I am waiting to take it to the dealer but prior to the steering and electrical, I told them on 10/12/21 oil service about the brakes feeling mushy and they said that’s the way they’re supposed to be. Only other passengers have witnessed the electrical and steering problem happen. At the exact same time the steering goes out the stability trek light flashes on the panel, the media screen goes out and my turn signal (if on) has no audio. I bought the car 3/26/21 @ 44,690 miles. On 10/12/21 I mentioned the brakes and about 2 months after that this electrical/steering problem started happening. It started out as little quirks but has progressively gotten worse. There is not 1 specific thing that seems to trigger the effect, it is variable.

While driving home from work, my car, lost power a few times. Though, the maintenance malfunction light did come on, it was while the issue was occurring. I mention this because, in the car’s manual, it states that the light will come on BEFORE the malfunction takes place. I finally made it home, however, the car did continue to lose power while driving. The next morning I took the car to my mechanic, who experienced the same issues, then did a diagnostic test and found these results: P0011; CAM Position; RCTISATOR BNK 1; TIMING OVER ADVANCE. Today while reading over all of the complaints, it is evident that this is a SERIOUS ISSUE! This malfunction is extremely dangerous and can prove to be fatal, due to losing driving power/car cutting off while driving. I am surprised that this potentially fatal malfunction is not considered to be a recall. PLEASE DO WHAT IS RIGHT AND SET A RECALL 🙏🏽 I also saw someone’s post that stated, there was a Recall and Free replacement on cars with the letters PP within the VIN#, we’re NOT BE SOLD or Leased in the US due to a Federation Violation and Restricted code. Somehow, I was sold one of these UNSAFE and BANNED vehicles. How do those who fall into that same category rectify this problem? Thank You for your help.

The blind spot detectors stopped working and a warning on the dash appeared saying "service side detection system". This warning pops up every time I turn on the car and the blind spot detectors do not work when I am driving.

The intake cam solenoid value failed without any warning. No light came on to warn me. The car would not accelerate and almost completely stop. I was entering a very usy interstate I - 20 and the car was stalling as other cars were speeding behind me. I could not accelerate at a safe speed. I made it to an exit. The car shut off . I put gas in because I was on a half tank. I thought it was gas related. I tried to leave the gas station the car cut off again. I had the car tolled to the dealership. I was told they didn't know why that happened. This was very dangerous to me with no warning that something was wrong. I could have been injured. Please explain to me what happen. I consider this a major safety issue. The vehicle was in motion on an interstate and stationary trying to go from a gas station.
