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.

LED lights are loose and rattle and flash all over the place. While driving over 40+mph or going over any bumps on the road . This only affects TRD PRO tundraâs with factory Ridgid lights . Toyota does not have a toyota approved repair even after going to dealership multiple times and calling toyota USA . They will not do anything for this safety issue besides offer lemon law options . Toyota states this is the only one with this issue . I have done research and brought this issue on a toyota trd forum and received over 100 complaints of other trd pro tundra owners with the same issue and toyota just gives them the run around . I brought this up to my toyota case manager and declined this is an issue . This can cause Photosensitive Epilepsy seizures and can cause serious injuries or death. Toyota has already replaced bezels once and issue persist they state they have updated bezel but have no ETA on when will be made available to be replaced. Toyota should make a recall on these trd pro tundras . My Toyota USA claim number is 220519001173

SEATS
4 Reports15% of totalPreviewing the first 2 complaint summaries.
The seat has been loose since I first purchased the truck, first time at the dealer they said it was the cushion which it wasnât and they ordered part and it didnât fix the situation. The next oil change I took it in and they said it was the frame, bottom of seat, and they ordered one and itâs been on back order a year now or thereabouts. Now Iâve owned the truck for over a year and a half and still no resolution. If an accident occurs will the seat completely break and fling me out of the vehicle? Anyhow multiple phone calls to dealership and now a phone call to Toyota themselves has yielded no resolution.

Vehicle is now 6 months old from original & new purchase. Within 30-days of ownership, (1) approx 1.5mm in size chip was fully repaired half way up from the front of the windshield. Eight hours ago (1) extremely small pebble, approx 2mm in size, contacted the front windshield 2 inches from lower portion centered in front of the driver and NOT in the area of the previous repair. Now, the same chip is a full length horizontal crack. Windshield material(s) seem to be extremely prone to failure and possibly not up to NHTSA or federal specifications...
