2021 Toyota Tundra Electrical Problems

Your instrument cluster display (the digital screen showing speedometer, fuel gauge, and other info) frequently goes blank while driving. You've taken your truck to the dealer at least 5 times over 18 months since purchasing it new, but the problem hasn't been fixed. This appears to be a software issue affecting the electronic control module of the instrument panel.

Your LED exterior lights are coming loose and rattling, causing them to flicker on and off when driving above 40 mph or hitting bumps. This issue affects TRD PRO Tundras with factory Rigid lights, and Toyota has not provided an approved repair despite multiple dealership visits and calls to Toyota USA. Toyota has replaced bezels once but the problem persists, and they mention updated bezels may be available in the future but have no timeline.

Your truck's radio and A/C sometimes don't turn on when you start the engine, and you have to jiggle the key or restart the truck to get them working again. This happens intermittently, not every time. The issue may stem from a faulty ignition switch or loose electrical connection that's preventing power from reaching these systems.

Wayne drove the truck to work. It was an icy day in Texas so he drove slower than usual. He went to pick up a part (for work) from another shop, he arrived at the shop, turned off the truck and went inside to retrieve the part for work. A few minutes later he came out to his truck and the hazard lights were blinking. He did not turn them on. He then noticed the cab of the truck filled with black smoke, he opened the door, raised the hood to take off the battery cables. The fire destroyed his dash and all electrical in the dash. There were no warnings or messages that appeared prior to the fire.
