Blind spot warning began displaying at startup. Turn signal bell and dash illuminators failed intermittently while driving. A Google search revealed the location of blind spot radar module. Inspected right rear module (located in bumper) and found corrosion. Difficult to remove module because of swollen internals. Pried open module after removal to expose corrosion damage to radar cells. The module mount location is openly exposed to road grime and salt. This infiltrated the module and ruined it because the module cover (white panel) is too thinly sealed.

The dash warning light indicated the blind spot warning system needs service. The passenger side warning light on the side view mirror stopped working. Subsequent internet searches indicated that the bumper module has gone bad. No response from the dealership yet. Other repair shops have quoted $400 to $860 to repair. This is a safety issue.

Vehicle started flashing multiple indicators on the dashboard, including those related to the charging system. Radio screen went off and then the power steering lost electrical boost while turning the steering wheel. Radio screen came back on its own but then it started cycling among its options (AM, FM, Bluetooth, etc) until settling in FM radio. Second occurrence was similar, although with different manifestations with the dashboard indicators although most concerning behavior dealt with the steering loosing boost almost causing an accident. Have reconnected the battery (changed about 4 months ago, currently showing 12.38V) and retighten the connections to the poles. Retightened the cables going to ground (they were NOT loose).

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 -€œService Power Steering-€ message appears on the center message board. A -€œService Stabili Trak-€ message appears on the center message board. A -€œService 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.

February 2021 Electronic parking brake activated while vehicle moving without being activated. Vehicle slid to a stop. This is a major safety issue for both the driver and other vehicles on the road as the vehicle is braking on its own and locking the rear wheels. Service parking brake light illuminated.

Dealer replaced parking brake module again. Issue reoccurred while in dealer possession. Dealer is now replacing all rear calipers, rotors, and pads at customer cost. Vehicle is a major safety risk as this issue causes the vehicle to unexpectedly brake and lock the rear wheels causing the driver to lose control.

Same issue I see multiple GM owners having. Service side detection system malfunctions after multiple repairs. Have had sensors replaced multiple times. I have had to every year at least if not every six months. Initially under warranty, but now no longer under warranty. I understand vehicles have issues, but the same issues over and over again is not okay. I have had where it shorts out my entire electrical system while driving. I literally feared for my life. Even the dealer acknowledges this is a known problem with GM service side detection system. It can happen at any time. It has never been longer than a year before the issue come up again. I am not even able to drive the car because of the issues the service side detection system causes. Either I lose all electrical in the car or it drains the battery so I cannot start the car. I honestly do not feel safe driving this vehicle. I only see the option once to indicate when it happened, so I will put the most recent occurrence.

Side detection modules keep burning out making my vehicle undrivable. Location of module is under rear bumper and is not protected by the elements. In snowy wet weather, causes failure. When module is burned out, nothing will work on vehicle. This is the 2nd time this has happened in one year.

On multiple occasions my cars electrical system will randomly fade in and out and shut down while driving. This is most evident in the power steering, radio controls and air conditioning. I have tested and replaced both the battery in the alternator. I have also brought the car into the dealership so they could run a diagnostics. Nothing can be identified as a central problem, but the issue still continues. It is very dangerous as I loose my power steering while turning. This happens on short trips and long trips and many times while on the freeway at high speeds.

2/15/2020 as I was leaving work at 10:08A.M as soon as I pulled out of parking lot and started to go my car shut down. I was going probably 23 mph: The steering wheel locked, pedal went to the floor, everything cut off. Thank god I was able to put it in park. I was blessed to not be in heavy traffic and could coast to the curb as I fought with the steering wheel to get out of the street. I tried several times to start it and it wouldn't, I got nothing, the car was completely dead. The keys wouldn't come out but I figured it out. Husband came, took out battery and took it to get checked out, it was 100%. I called a roadside service to have it towed to Chevy, where I bought it in 11/2015, but when my husband was reconnecting the battery the car came to life. I called and cancelled the towi, drove her home no problem; however, something is definitely wrong 😕this care is getting traded soon no more Buick for me🙋

The side detection monitor kept saying needed to be service, then it progressed to it not turning off, and now all of the gauges on my dashboard states that it needs to be serviced: Airbag, theft deterrent system, and the tire monitor system. In addition the heat will turn on and off and so is the radio.

The contact leases a 2014 Buick Verano. While driving, the vehicle stalled without warning. The vehicle was restarted and was able to drive, but the failure recurred. In addition, all the warning indicators randomly illuminated and all the door locks went up and down. The failure recurred numerous times. The vehicle was taken to the leasing mechanic who diagnosed that the wiring underneath the vehicle was loose, which caused all the warning indicators to illuminate. The vehicle was repaired. The failure recurred two weeks later and the vehicle was taken back to the same leasing mechanic where it was currently being repaired. The manufacturer and dealer were not made aware of the failure. The failure mileage was approximately 179,000. The VIN was not available.

I've only had the vehicle a year some change. Parking break light comes when I turn the car off and goes away once I put it drive or reverse. Power steering locks on me when turning especially on the highway which is so dangerous. Also so many electrical problems with the computer in the vehicle that cause the door to lock and unlock on its own when I try to put on my fog lights the engine may rev

The contact owned a 2014 Buick Verano. While driving, the contact's two year old child wanted the rear windows rolled down. The contact looked up and noticed smoke coming from the rear of the vehicle. The contact pulled over, removed the child from the vehicle, and attempted to extinguish the fire. The contact stated that the fire was coming from the rear window. The fire grew too large and was out of control. The fire department was contacted and they extinguished the fire. There were no injuries. The vehicle was towed to a local tow yard. The vehicle was totaled. The manufacturer was made aware of the failure and did not assist because the contact turned the vehicle over to her insurance company. The dealer was not contacted. The cause of the failure was not determined. The failure mileage was 72,000.

The side detection system has failed so I no longer have mirror blind spot protection. The problem is also causing problems with the instrument cluster failing. The issue is exactly like the one covered by bulliten 16-na-178 for other GM vehicles of the same model years which use the same system. GM should recall all the cars that used this system, not just some as it is a serious safety issue as the whole cluster can go dead while the car is being driven.
