Some Chevrolet Trax owners report experiencing issues with the radio staying on after turning off the car and opening the door. This problem may be linked to a malfunction in the driver's door lock assemblies, which can cause the system to incorrectly detect that the driver's door is open. Additionally, some owners find that a faulty power button on the radio unit itself can lead to unexpected activation of the radio, necessitating a replacement of the unit. Electrical system malfunctions, such as problems with the ignition switch or wiring, may also contribute to this issue, requiring inspection of the head unit wiring and ignition components. Furthermore, battery problems can prevent the radio from receiving the correct signals to shut off. To address these concerns, owners are advised to contact a GM dealer if under warranty, hold the power button on the radio as a temporary fix, and ensure the battery is in good condition.

Some Chevrolet Trax owners report experiencing intermittent issues with the radio and screen going blank, which may be linked to electrical system problems. These issues could stem from a weak alternator or battery, as noted by several owners. Additionally, problems with the head unit or body control module have been identified as potential contributors to the screen malfunctions. There has also been a recall related to intermittent blackouts of the instrument panel display, which could be associated with the reported screen issues. To address these problems, General Motors offers a software update, and inspecting the wiring harness for any issues may help diagnose the situation. It is advisable for owners facing these concerns to consult with a mechanic or authorized service center for proper diagnosis and resolution.
