Hello, Noticed the fuel gauge was reading full after retrieving boat after a day of fishing. Before launching the boat the gauge read 1/2. Filled up at the gas station with the needle on full and it took approximately 16 gallons. The Toyota dealer said they could find no problems and reset the gauge. Running out of gas could be a serious problem towing a boat. Thank you

The tailgate opens on its own while I am traveling down the highway. I now have to brace anything I put in the bed of the truck lest the tailgate opens on the highway and I spill my load and cause a catastrophic injury or death on the highway. When shifting into Park, having to keep my brakes firmly engaged due to a periodic and rapid acceleration of the engine. At cruising speed, on the highway, a vibration that only occurs when climbing hills coupled with a rapid pulsing of the engine/transmission. At cruising speed, on a level ground, the transmission rapidly disengages and reengages. Weekly I have gauge and infotainment malfunctions wherein I have to turn off the truck and restart it to make the gauges work. The gauges just freeze and fail to respond. The compass flips direction. Malfunctioning gas gauge. The backdoors lock and will not unlock. Occasionally, when they lock, I have to crawl into the backseat, from the from seat and manually unlock the door from the inside of the truck. A flat tire where when I went to change it, the jack bent…in my driveway. I now have to carry a 3rd-party jack and tools to handle emergency repairs. A regular malfunction of the rearview mirror. A cracked drivers seat. 6-months after purchasing the truck, the door trim came off in my hand. When I spoke to the Toyota tech, he advised me that this was not covered under warranty, and suggested that some customers keep the trim off as “most of the trim was installed with double-sided tape and would just fail again”. Though, to be fair, he did offer to, at several hundred dollars a pop, keep replacing the trim every couple of months. While my Truck is parked in the garage, when the trucks system does an update, it opens my garage door.

Fuel gauge randomly resets itself to full. This could lead to the vehicle running out of fuel without the driver knowing that it was low. Confirmed by dealer via video evidence of the vehicle taking 14.4 gallons to fill when the gauge read over 3/4 tank (tanks is only 32 gallons).

The fuel gauge will randomly reset itself to full. This poses a safety concern as the truck may run out of gas while it is showing that it is not empty. This could happen while doing something like pulling out in to traffic or turning across a lane of traffic. This affects many trucks, not just mine.

When I drive the vehicle for a period of time and use a 1/3 of the fuel in the vehicle and park on non level surface: Meaning the front of the vehicle is pointed up and rear is lower the fuel gauge will register full on vehicle restart. Even if I drive the vehicle around and park it on a level surface and restart the vehicle it still fails to show the correct amount of fuel in the vehicle. In addition it will slowly subtract fuel based upon driving that is inline with normal fuel usage: It never registers that you are actually 1/3 lower then indicated on the gas gauge. I have identify two ways to address the issue of the gauge not registering the correct amount of fuel in the tank: 1) Refill the truck with maximum amount of fuel 2) Disconnect the negative battery terminal, let the truck sit for 30 seconds, and then reconnect the negative battery terminal. It will then register the correct amount of fuel in the truck The safety concern is I could run out of gas in unsafe manner on the road.

On multiple occasions my fuel gauge has randomly reset from 3/4 full to above full. Had I not noticed this change I could have run out of gas. Toyota refuses to do anything about this and I have reported this to corporate and two different dealerships. Taken it in for repairs 4 times. They tell me there is nothing they can do???

Fuel Gauge is always showing incorrect levels. When fueld up to full at times the gauge will show 1/2 tank to 1/4. Then other times if I know I have 1/4 tank of fuel left the gauge will show as full tank. Very unreliable and concerned whether I have a fuel leak or what not

When parked on a slight incline facing uphill (~5°) fuel gauge began reading full. Fuel level prior to parking was 1/2 tank. Fuel gauge was stuck reading full for several days. Dealership unable to resolve.

I fueled my vehicle and once I started my car my fuel gauge remained the same, as if I never put full. I turned off the my vehicle and stared it again. The fuel level still did not change. I went to another pump to see if there was actual fuel from the other pump that went into the vehicle. The other pump stopped right away, signaling I had a full tank. I drove around for 15 minutes but no change to the fuel gauge. I parked the vehicle at home and planned to take it into the dealership the following day, but my fuel gauge corrected it self later displaying a full tank. I’ve seen in the forums this has been a problem. There was no warning lights or CELs upon this problem.
