2021 Toyota Tundra — Known Issues & Recalls

Your driver's seat rocks back and forth excessively when you stop or turn, despite visiting the dealership three times since July 2021. The dealership has attributed this to a seat track issue and suggested raising the seat height, but this hasn't resolved the problem, which has gotten progressively worse over time. You're concerned the seat could collapse during normal driving, and this feels like a significant safety issue that needs proper repair or seat track replacement.

Your driver's seat has been loose since you bought the truck. The dealer initially thought it was the seat cushion, but replacing it didn't fix the problem. They then identified the issue as the seat frame and ordered a replacement part, which has been on back order for about a year. You're concerned that a loose seat could be dangerous in an accident, and despite multiple calls to both the dealership and Toyota, the problem remains unresolved.

Your driver's seat shifts side-to-side when you make slow, downhill right turns. The dealer inspected it and said there's nothing wrong, but the movement is noticeable enough that you're concerned about it.

Your seat moves back and forth when you brake or accelerate. You've reported this issue to two different dealers, but the problem hasn't been fixed. This indicates a mechanical issue with the seat track or mounting system that needs attention.

Snow buildup on your windshield caused excessive stress on the driver's side wiper arm, which stripped out and stopped working. You've discovered that Toyota no longer manufactures the replacement wiper arm (part #85221-0C021), leaving you unable to safely operate the vehicle in rain or snow. Resolving this issue will likely require either finding an aftermarket wiper arm replacement or exploring warranty coverage options with Toyota.

Your windshield has developed two chips within 6 months of ownership. The first chip appeared within 30 days and was repaired, but a second small impact from a pebble recently caused a full-length horizontal crack near the bottom center of the windshield. You're concerned that the windshield material may be defective or not meeting safety standards due to how easily it's cracking from minor impacts.

Your driver side windshield wiper doesn't work, while the passenger side works fine. The wiper stopped working suddenly without any warning when you tried to use it. Since your car is due for state inspection, this issue will likely need to be fixed before passing.

Your power steering system failed at 38,000 miles, requiring a complete replacement of the power steering assembly at a cost exceeding $6,000. The dealership indicated this is a known manufacturing issue that affected a significant number of 2021 model year vehicles and prompted a recall. The repair will involve replacing the entire power steering assembly.

Your 2021 Toyota Tundra is subject to a recall (Campaign 21V920000) related to the steering system, but the replacement part hasn't been available yet. You've been waiting longer than seems reasonable for the dealer to complete the repair, and you've notified Toyota about the delay. You haven't experienced any steering problems so far, but the manufacturer is aware parts are taking too long to reach dealerships.

Your moonroof suddenly shattered and broke apart while you were driving, with no clear cause. This happened without any impact or accident. The repair will likely involve replacing the entire moonroof glass panel and checking the sunroof mechanism for defects.

Your air conditioning system doesn't have a proper drain for condensation water, so moisture is accumulating and causing electrical problems in the AC housing. You noticed a cone-shaped component that appears to be poorly designed for water drainage. This issue may require Toyota to redesign or recall the AC drain system to prevent water damage.

Your airbag system failed to deploy during a serious accident on the freeway. There were no warning lights or signs from the dealer that anything was wrong with the airbag system before the crash. This will require a complete airbag system diagnosis and likely replacement of the airbag module and sensors.

Your sunroof glass suddenly shattered and exploded while you were driving on the highway during a heavy rainstorm with your family in the vehicle. No crash or fire occurred, but this is a serious safety concern as flying glass could injure passengers. The repair will likely involve replacing the sunroof glass panel and inspecting the sunroof frame and seals.

Your 2021 Toyota Tundra suddenly stopped running while you were driving, with no warning lights before the engine stalled. A Toyota service center diagnosed the problem as a failed fuel pressure module and fuel pump. The owner notes that other Toyota model years with the same fuel system have recalls for this issue, but the 2021 Tundra does not. The fuel pump and pressure module will likely need to be replaced to restore engine operation.

While driving your 2021 Toyota Tundra, you experienced a brief hesitation and jolt, and the transmission warning light came on. Your dealer diagnosed a transmission failure and determined the entire transmission needs to be replaced. This issue occurred at 48,000 miles. Fixing this will require a full transmission replacement.

When you try to fill up your gas tank, fuel is backing up and spilling out onto you instead of flowing into the tank. This has happened twice — first around 18,000 miles and again about a year later — and your dealer couldn't figure out why. You've noticed it happens when it's extremely hot outside (over 105°F) and your tank is about a quarter full after several hours of driving. The fix will likely involve inspecting or replacing the fuel filler neck, vent system, or related components that may be causing the fuel to back up.

Your pre-collision warning system has activated more than 10 times on the same stretch of road even though there were no other vehicles, pedestrians, or animals nearby. This false alarm suggests the system's sensors may be malfunctioning or misinterpreting road conditions. The fix will likely involve diagnosing and recalibrating the forward collision sensor system, or potentially replacing faulty sensors.

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.
