If your vehicle is showing radio or infotainment screen reboots randomly while driving, here are the most likely causes and the parts you'll need to fix each one.
Bumps in the road can cause momentary voltage drops if the battery terminals are loose or heavily corroded, forcing sensitive electronics like the radio to restart.
If the radio was recently replaced, loose wire crimps, a poor ground connection, or a faulty wiring harness adapter will cause power loss over bumps.
Modern infotainment systems are essentially computers that can crash and reboot due to software bugs, memory leaks, or internal overheating.
An alternator that is failing can produce severe voltage spikes or drops. The radio will often shut down and reboot to protect itself from this irregular voltage.
The electrical contacts inside the ignition switch can wear out over time. Heavy keychains and road vibrations can cause the accessory power to momentarily cut out.
