Why does the Verano center control screen touch malfunction?
3 Answers
There are two possible reasons for the black screen of the car's center control display: unstable power voltage of the car, or issues with the cables on the back of the center control display. No response when pressing buttons on the touch screen: If there is no response when pressing buttons on the touch screen and control cannot be achieved, it indicates a touch screen drift phenomenon. Simply re-enter the touch screen settings page to perform touch range calibration. Touch screen has display: If the touch screen has display and buttons respond when pressed but control cannot be achieved: the RFID of the touch screen does not match the RFID set in the host program, the ID of the wireless receiver does not match the ID set in the host program, or the wireless receiver is beyond the effective distance.
My buddy who's been fixing cars for over a decade says the touchscreen failure on the Verano is pretty common. Most likely it's caused by those cheap tempered glass screen protectors - they mess with the touch sensitivity, but peeling them off usually fixes it. Another possibility is oil or sweat smudges on the screen - try wiping it gently with an alcohol-dipped microfiber cloth. If restarting the infotainment system doesn't help, there's probably a loose connector issue, especially if you frequently drive on bumpy roads. Here's a pro tip: smartphones placed on the wireless charging pad can cause signal interference - try moving your phone away. If it's truly a hardware failure, you'll need to replace the touchscreen, but DIYers can save big by buying parts from Taobao.
I've seen many cases in my auto repair shop where Verano owners complain about touchscreen malfunctions. The most common issue is the system freezing up, just like how a phone can lag after prolonged use. Try holding down the end call button and the asterisk key simultaneously for 10 seconds to force a reboot. High temperatures inside the car during summer can also cause the screen to stop working, so try parking in the shade next time. Another easily overlooked issue is an outdated system version—visiting a 4S dealership to update to the latest system might solve the problem. If rebooting twice doesn't help, it's likely that the touch layer is damaged. A common flaw with Buick cars is the fragile wiring of the center console screen. Replacing it yourself requires dismantling the entire dashboard, so it's better to leave it to a professional.
