The Service Side Detection System (SSDS) maintenance light appears on my dashboard and remains unless I cancel it out by pressing the menu button on the turning signal. Both sides of the vehicle cannot accurately detect when vehicles are approaching and passing...the SSDS indicator lights in the side mirrors come on and off randomly. Currently, my left mirror indicator light remains lit even when the vehicle is turned off. The problem started with my fan...it stopped blowing air. I made a stop and when I restarted my vehicle the fan started again. This problem started about 6-8 months ago. Now...it is getting worst...I am getting errors on all my systems when I start my car. Yesterday, I couldn't turn my car off...finally when I did, I couldn't start it. I was not able to engage the brake pedal and couldn't turn over the vehicle. …
My vehicle was rear ended and when the wire connection was detached there was signs of corrosion cause by moisture. The insurance company wont pay for it because the Buick mechanic said this is a common issue with Buick Verano's. When moisture gets into the connectors all instruments on the dashboard goes haywire. it's my belief that this may cause the car to stall and if that happens no power steering or no power breaks.
Vehicle is showing P138 code, and goes into limp mode and shows stable-track indicator. Has been checked by 2 mechanics, accelerator pedal, and throttle body have been replaced, with same results. This creates a severe hazard while driving.
Upon starting the car we have no working guages. The temperature and gas level don't work. And the following error messages show up on the dash. Service air bag, tire monitoring system, front camera, parking assist, side detection system, and theft deterrent system. The car it basically undriveable. The blinkers do not work, heated seats (though that is minor) radio stops working. We don't know what the temperature of the engine is, how much fuel we have and how fast we are going. There is only 68,800 miles on it. When I call the dealership (they're the only ones with the technology to look at this and troubleshoot) they tell me it's a few hundred dollars just to run diagnostics. This is ridiculous that the car is this unsafe to drive but I have to pay to diagnose it. Then I find out just to replace the side detection system will cost me like $700. …
I purchased my Buick Verano on 12/29/2017. During the first while driving my eletrical system just shut down about 2-3 times. In the second year it started happening more often while making a turn or just going aroun another vehicle. From July to August the electrical system shut down about 5 times in about a 5 week span which made it very hard to steer the vehicle and all of the radio screen shut down also. This issue has me worried because at high speeds if this happens it will be very hard to control the vehicle. I have noticed that this is a common problem with this vehicle. Has the car dealers acknowledge this issue and what do they recommend to do?
The lights on the dashboard work, and nearly every service light and message pops up. None of the gauges on the dashboard work including the speedometer and gas meter. The turn signal works but doesn't show it inside the car. The radio has to be turned on manually when getting in and out of the car. The radio will randomly shut off when driving. I've been sent away from dealerships before with no answer claiming that all modules are giving a reading so they do not know what the problem is. My cruise control has shut itself off a couple of times while driving. This car is a 2015 and is far to new to be dealing with a safety hazard like this.
It all started with the side detection system. Told me to have it serviced, as I was on the high way the electrical stated going crazy. Gauges going back and fourth constantly, radio turned off, fans turned off, and blind spots kept blinking. The mechanic found a corrosion issue. They were able to unplug it but it also made it so my rear brake light on the right would not work (which is illegal). It would cost me over $1,000 to fix this issue since the corrosion isn't covered by the warranty. This vehicle was made with a faulty item going out of the factory that way. I am appalled in GM for letting a vehicle go out on the street this way.

Certain systems of my car while I am driving will shut down. For example I will be taking a turn and the power steering will go out. Other things that seem to shut down either at the same time or separately are the radio/ screen, the cruise control, blinker, ect. This has been an issue especially when I am turning and the power steering goes out. I looked online to see what May be the problem and noticed plenty of other people have had these issues as well with no one being able to find a solution.
