2022 Toyota Tundra acceleration problems

Filed Sep 10, 2026 · Acceleration, Fuel system · CO

On September 1, 2026, my 2022 Toyota Tundra experienced a serious loss of accelerator response while I was leaving a gas station and entering traffic. I pressed the accelerator, but the truck provided effectively no acceleration, leaving me partially in the roadway. An approaching vehicle had to swerve into the opposing traffic lane to avoid a collision. I had experienced a similar low-speed loss of accelerator response within the prior two weeks. On September 2, while traveling on I-70 at approximately 70 mph, the truck experienced a separate loss-of-power event. Engine RPM dropped considerably and the vehicle felt as though it were coasting. I pressed the accelerator firmly, but it did not respond normally for approximately 5-10 seconds before power returned. Radar/adaptive cruise control was not engaged. I immediately took the truck to Western Slope Toyota. Technicians checked for codes, performed multiple road tests and recorded vehicle data but could not reproduce the intermittent failure. The issue was escalated to Toyota technical assistance under TAS Case 262460664. This problem has been documented by Western Slope Toyota since 2023. Toyota's applicable TSB repairs were performed on prior occasions in an attempt to correct the throttle/hesitation problem, but they did not resolve it. In 2025, the dealer again documented the condition after the earlier TSB had already been performed. According to the September 2026 repair documentation and my discussion with the Western Slope Toyota service manager, Toyota's specialist technical team is aware that the condition can remain despite the TSB work. The repair order states that Toyota identified a known hesitation concern that remains under investigation and that there was no repair to be made at that time. The condition is intermittent and unpredictable and can cause loss of accelerator response or motive power at low and highway speeds. I believe it creates a serious crash risk. Current mileage: 58,735.

In this vehicle, I regularly experience a "delay" in gas pedal response. I drive a non-hybrid V6 twin turbo variant engine 2022 Toyota Tundra, and for a long time I thought this was just related to turbo spooling delays. But Toyota's recent TSB-0032-26 publishing last month confirmed that it is actually a TCM logic issue requiring a re-flash. I spoke to the dealership and this is not covered outside of the standard 3-year bumper to bumper warranty, and they wouldn't cover it under the powertrain warranty which lasts longer, even though this is technically a power train issue. This concern has left me challenged with timing gas pedaling from a full stop, often with a noticeable 1-2 second lag before the truck responds. I have had a couple of close calls because this behavior inhibits safe judgement calls for acceleration. Especially from full stops this is most noticeable, but also when you are trying to accelerate suddenly, there's always a brief delay.

Hesitation/Lag Acceleration and Stop.

Engine hesitation from a stop. Engine takes 1-2 seconds to respond to throttle pedal input. Creates timing safety hazard when attempting to cross oncoming lane to enter roadway. Puts vehicle at risk of not clearing the oncoming lane in time to avoid collision. Intermittent and haven’t been able to reproduce with dealer.

Vehicle failed to accelerate after I attempted to merge onto 3 lane road from a driveway. No chimes, warning or emergency braking occurred but the vehicle had no response for a second or two. I captured the incident on my dash cam. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a throttle lag when I depress the acceleration pedal, the vehicle doesnt not move for a period of time ranging from 0.5 seconds to 3 seconds. This is more prominent when performing a creeping start where the vehicle has not fully stopped.

On a cold start, or if you drive with the vehicle in normal mode, from my understanding, vehicles are now fly by wire, the computer has a lag that if you attempt to pull out in front of someone, the truck will simply fail to go, then after a delay.It will take off like a rocket, to circumvent this issue, I have found.If you drive in sport mode, it tends to have less of a delay. But it's a serious safety concern.Along with the other issues with these vehicles, I have had a few close calls, where the throttle response was incredibly delayed.

The vehicle hesitates when starting from a stop. It feels like the engine dies. This was a previous “recall”. Vehicle was “fixed” but still happening. I’ve informed Toyota of issue. No resolution. I’ve almost been hit twice at an intersection because of this.

The truck has a hesitation to start from stop/slow state. This is concerning because when I start to accelerate, sometimes it doesn’t want to go for a 1-2 second time period making it unsafe to pull into traffic. It is sporadic and seems to happen more when I start and stop in quick succession.
