2023 TOYOTA TUNDRA Complaints

The contact owns a 2023 Toyota Tundra. The contact stated that the vehicle was not obtaining the correct fuel mileage. The contact stated that, while tracking the mpg, the vehicle was averaging 15.7 mpg. The difference was approximately twenty percent less than the sticker mpg. The contact stated that the mpg sticker stated that the mpg would be 20 mpg. The contact stated that when the vehicle was purchased, he was not provided two keys. The contact stated that while his wife was using the key, the key detached and was lost. The chip was still in the fob, and the contact was able to open the vehicle. The contact stated he was concerned about not having an additional key. The contact was unable to obtain the second key for the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, who test drove the vehicle and the vehicle was averaging 12.2 miles while driving in the town. The dealer informed the contact that the extra batteries in the vehicle might account for the difference in mpg. The dealer completed a wellness check and informed the contact that the vehicle was working as designed. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 50.

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.

A few complaints: #1: First is the infotainment system continuously requests a pin be entered. I would enter the pin, but the pin screen pops up again and again whenever the system is on. Had the dealership look at it, they stated the info system has the latest software and I was instructed to contact Toyota. After a 2+hour phone call, resetting app passwords a few times, resetting pin a few times, starting the truck a certain way, and other things I cannot completely remember, finally got it to accept the pin and stop pin request screen from popping up. That worked for about 1 week, and since then the screen pops up. I no longer try to enter the pin just hit the x button (kind of hard and dangerous entering 6 digit pin 30 times while going 75 on the highway). I would estimate screen popping up about every 1-2 minute. #2: Truck has 6,400 miles on it, brakes started squealing around 4k miles or less, getting progressively worse. I have tried washing brake dust away at car wash, no help. Sounds like when a car is getting to the last of the brakes. Are they that worn in 6k miles, I hope not, but how am I supposed to know when or if they need to be replaced? Very annoying, and dangerous since I can't rely on the brakes squealing to let me know need replaced. #3: 1 week ago after stopping at a red light, about 5 seconds passed when the truck jerked violently and slightly moved forward, all while I had the brake pedal pressed. It was so hard I was certain I had just got rear ended, but as I looked in the mirror preparing to get out of the truck, I saw the car behind me was barely approaching 20+ feet back. This is only time it has happened so far, but very concerning, will let the dealership know as well, but I can already hear their response "we weren't able to replicate the issue". Fuel line recall, still haven't fixed it (but will be setting appointment to take it in for all the described things, again, and hopefully get my 2nd key, been 9 months already).

In some cases when slowing down to a very low speed an trying to to accelerate again. There can be either a brief (1/2 second) or a very long ( > 1/2 second) delay between pressing the accelerator and the engine responding. Because of this delay its very hard to gauge when and how the vehicle will respond. In some conditions this can be a safety concern as the vehicle behaves unpredictably. I was able to verify this with engine logging data the data shows that the computer acknowledges the accelerator position but fails to advance the throttle or by any means add power for a period of time and then behaves in a expected manner after a delay between 1/2 to 1 second. The best I can gather the problem happens in a timing window when the transmission shifts from a higher gear to 1st gear. I took into the dealer who also verified the concern and opened a TAS case with Toyota. TAS took my data but provided no information or guidance to the dealership.

When attempting to accelerate, the vehicle idles down and fails to accelerate for a period of 2-3 seconds. To initiate normal acceleration, fully depressing the accelerator pedal is required vs. a gradual depression of the pedal.

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.

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

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???

Unknown. No incident yet. Concerned driving far. Recalls been 4 month and no action yet. Would like a refund of my money or a replacement vehicle. Also my tailgate feel off my tire pressure system comes on and tires are fine vehicle is a lemon.

Vehicle leaked fuel onto the garage floor. This is a fire hazard for my home and the hybrid vehicle. The dealership is currently inspecting the issue, and have stated they could not find the source of the leak at this time. There were no warning messages or lamps.
