2022 Toyota Tundra

While on highway truck decelerated on its own. We were trying 70 mph and the truck dropped to 60 mph while the gas pedal was still manually engaged. Its becoming an increaingly regular problem that the car will not accelerate from a complete stop, even with gas pedal fully engaged. Potential for accident is high, as there is no reliability when pulling out into traffic. Dealership ran diagnositic check during service, was unable to pin-point issue - - is also 2 to 3 months out on service schedule, so issue was reported early June to dealership but unable to service vehicle until mid-August. Dealerships advice was to report directly to Toyota - since no recall remedy was issued for engine issue and the acceleration issue isn't specifically named in their most recent recall for the 2022 model.

On 07/10 while accelerating from red to green light, at around 50mph truck shook and alerted my attention to dash/odometer because of immediate slowing of truck. Noticed alert for “Engine Power Loss” and “Brake Failure” and instructed to see dealer. Could not go above 30mph at 2500rpm, thankfully I was 5 minutes from home. Had Tundra towed to dealer. They got Toyota involved and started a case. As of 07/12, dealer was instructed to reset engine valve settings, cleared alerts, and did normal schedule maintenance. I was instructed to drive directly to dealer or pull over where I was and have a technician drive to my location so they could further assess this issue. As if they work 24/7 and would drive outside of city limits…I put 100+ miles a day on my truck for my work commute.

At certain times, when coming to a stop, and then attempting to proceed, the throttle with delay or lag from a stop. This has happened since the start of ownership in Feb 2022 up until today. Toyota has issued on previous Technical Service Bulletin (TSB) - T-SB-0111-22 - that Toyota states should resolve an issue with "Hesitation From Stop and Surge Concerns". The TCM -Transmission Control Module - logic has been modiWed to address these conditions. According to Toyota, this updated logic SHOULD keep this from happening. This TSB was released December 16, 2022. To date, this issue continues to occur. The only way to keep it from happening is to Reset the TCM Learning. This requires the battery to be unplugged for an extended period of time. There was a subsequent TCM logic update for Recall 24TA02 (NHTSA Campaign Number 24V125000). It would seem that this TCM Logic Update has actually caused this condition to be present more often. This is something that we have expressed to our Service Consultant at every visit and it is still occurring over two years later. We have had this happen multiple times while attempting to proceed through a 4-way stop, as well as trying to merge into tra`c in slower moving city streets. There are members of an online forum who have been able to record the data aow and show when and how the delay occurs. Other than December 2022 TSB, Toyota has not acknowledged this issue even though it continues to occur on the MY22+ Tundra/MY23+ Sequoia, as well as the MY18+ Lexus LS 500. I am lead to believe this is a result of the programming for the Direct Shift 10- AT from Aisin/Toyota and/or the V35A-FTS, both Type '17 (LS 500) and the Type '21 (Tundra/ Sequoia).
