Toyota Tundra sudden acceleration problems

Filed Oct 13, 2026 · GA

Subject: Safety Complaint – 2025 Toyota Tundra – Sudden Acceleration Delay – T-SB-0032-26 – Two Near-Accidents. I am the owner of a 2025 Toyota Tundra and am filing this complaint to report a serious safety concern involving delayed acceleration from a stop or near-stop condition. My vehicle has experienced this problem on two separate occasions. When I attempted to accelerate, the truck did not respond as expected, creating a dangerous situation and nearly causing a car accident on both occasions. The delay in acceleration left me unable to move forward as quickly as required by the traffic conditions. I am concerned that this issue could result in a serious collision, injury, or loss of life. I understand that Toyota issued Technical Service Bulletin T-SB-0032-26, titled “Hesitation from a Rolling Stop,” addressing hesitation from a rolling stop or quick stop on certain Toyota Tundra vehicles. My experience appears consistent with the condition described in this bulletin. I took my truck to Toyota Service in [XXX], on two separate occasions to have this issue inspected. On both occasions, the service department declined to identify or address a problem, stating that there was nothing wrong with the vehicle. As a result, I remain concerned that the safety issue has not been properly investigated or resolved. I believe this matter warrants the federal safety agency's attention because an unexpected delay in acceleration can create a dangerous situation when entering traffic, crossing intersections, or responding to changing road conditions. I respectfully request that the federal safety agency Review this complaint and investigate the delayed-acceleration issue affecting my 2025 Toyota Tundra. Examine whether the condition described in Toyota Technical Service Bulletin T-SB-0032-26 represents a safety-related defect. Investigate whether affected vehicles require a mandatory safety recall or another appropriate corrective action. I appreciate the prompt solution to this issue ASAP.

Unintended acceleration. When you stop the truck, and have the brake on, the rpms go down to idle ~650. As soon as you lift the brake, without touching the accelerator, the vehicle starts ramping up the rpms and moving. On level ground it will go to 1000 easily before you have to stop it. It will pull up a grade even while towing my boat. If you're in a line a traffic, say at a traffic light, and the light changes, traffic moves and the car ahead takes off their brakes, and you do same, the truck starts moving faster than the vehicle ahead without touching anything. It's idling too fast without the brake and doesn't stay at idle once the brake is off before you push the accelerator. First the dealer told me everything was "Normal" - it's supposed to do that. I've been driving vehicles since 1962, so I think I know what I'm talking about. They told me to call Toyota. Toyota started a case. They took it in for an factory inspection because I think this might be related to a non highway collision with a bldg, I had shortly after I got it, I'm not sure. I put into park in a parking space but apparently it didn't engage, only into reverse. I was looking for something and the truck started backing up and hit the gas station bldg close behind. The anti-collision was off, because you have to turn it off to tow. And I hadn't turned it back on yet. This truck has way too many audible alarms and very annoying, especially when backing or exit the vehicle. I don't need to know that I'm out of the vehicle.

Tundra has had and has throttle lag. Lag is so noticeable that other drivers notice. Following lag is a burst of power causing a jerk and or lunge forward. This is after a long pause. Happens on a roll, or start-stop situation. My truck has had the toyota tsb applied a long time ago.

I have experienced consistent vehicle jerking since the time of purchase, despite acquiring the vehicle brand new. This jerking typically manifests when maintaining a constant speed between 35-40 mph. Additionally, the vehicle occasionally exhibits a complete lack of acceleration. A particularly concerning incident occurred when I was attempting a left turn from a side road onto a main street with a 40 mph speed limit. Despite assessing sufficient time for the maneuver, the vehicle stalled for approximately one second upon acceleration, leaving me in the middle of the lane with approaching traffic. Similar instances of delayed acceleration have been observed when attempting sudden acceleration after a rolling stop.

First I had my engine replaced in May 2025 under the recall and service advisor informed me it would be about 3 days before they completed the engine swap and it had to sit to make sure there were no leaks anywhere and in less than 24 hrs the called me and told me my truck was all done. I went to pick my truck up they had it waiting in the service line with the engine running, I heard a strange ticking noise coming from under my hood that sounded like a lawnmower engine, the service tech tells me that is normal with the replacement engines which is absolutely false. Being a woman they tell me I don't know what I'm talking about. I got frustrated and got in my truck and when I came to the first stoplight when the light turned green and I stepped on the gas pedal, my truck would not move, after about 5 seconds it surged forward and then again wouldn't move, then again my truck surged forward with a loud thud in the rear like somebody hit me from behind. It feels like it isn't kicking into gear and also my steering wheel was not centered when they swapped the engine so I have to hold my steering off to one side for my truck to drive straight. This has been a nightmare for me and Toyota refuses to acknowledge there is anything wrong. I've also been waiting for 7 months to get my front brakes fixed under the TSB and all they say is we don't have parts available, meanwhile they're building new trucks with new brake pads, rotors and calipers before taking care of the people waiting months and months? They try and wait until your warranty runs out so I have to pay for the fix. Please help. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Since the first day I've had the truck, I've experienced a lag/hesitation from a full or rolling stop. The truck will start to move, then have no power for a few seconds and then will surge forward. This has almost caused accidents - when I push the gas I expect the truck to GO.

Sudden maximum acceleration accompanied by brake failure, without warnings, occurred on my 2002 Toyota Tundra 4.7L V8 causing loss of control of the vehicle, which ended in a rollover crash, resulting in total loss of the vehicle and injury to me. While departing a 25 mph zone (sign read "END 25 SPEED LIMIT") on a relatively straight section of the road, I very gently accelerated from 20 mph to 30 mph. As soon as the vehicle reached 30 mph, sudden maximum acceleration occurred. Taking my foot off of the gas pedal, first I verified that the gas pedal was not stuck or blocked, but the gas pedal was in the fully up position. I then pressed the brake pedal very hard, but it was locked in the fully up position and the brakes would not engage. I then verified that nothing was blocking the brake pedal underneath it. At that point, around 3 to 4 seconds after the sudden acceleration began, I had entered the first turn of a 30 mph "S" turn at a high rate of speed, while acceleration continued at the vehicle's maximum acceleration rate beyond my control with the brakes not engaging. In order to avoid collision with a camper motor home and a small car following it, I went into the oncoming traffic lane at the second turn of the "S" turn. My truck fish tailed and struck a reflector marker on the left side of the road. To avoid going down a 50+ foot, nearly straight down drop on the left side of the road, I turned right. To avoid striking the motor home, I turned left, then right again to try to gain control. My truck rolled on its left side and landed upright on the right side of the road. It had been accelerating at its maximum acceleration rate with the brakes failing to engage and fish tailing the entire time. The problem appeared to be a catastrophic failure of the electronic throttle control and/or related electronic systems.
