This is a reoccuring issue and happens daily. When the vehicle is cold and sitting all day or all night, on the first 5 minutes of driving or so, when you push the accelerator pedal from a dead stop or rolling stop, there is no throttle/engine response for at least 1. 5-2 seconds. This is a highly unsafe condition and can lead to a traffic collision. I have reached out to Toyota corporate about this and they said to bring it into my local dealer, dick hannah Toyota in kelso, wa to perform the rolling stop TSB that is out on these Tundra trucks. I received information from dick hannah that when they went to perform the procedures to take care of this TSB, that it had already been done and that there was nothing they could do further. They asked me to document the conditions to try and get Toyota corporate to do something about it. I asked if there wasn't a recalibration they could do or anything else to make this condition improve, and they said no there is not. I expressed my concerns saying that there is nothing to document, that this happens everyday and is a daily occurence whenever the vehicle has been sitting for a long period of time. I have reached out to other vehicle owners on vehicle forums on the internet that are experiencing the same exact problems with no remediation from Toyota dealers or Toyota corporate. I was even offered to get into a split to hire a lawyer to get this unsafe condition remedied. This is a big deal and should not be overlooked and written off by anybody.
The vehicle is either unresponsive or has a severe throttle delay from a stop or a very low speed, creating is a major safety issue. This could leave the vehicle in a position to not be able to accelerate, and risks becoming a hazard to other traffic, particularly at intersections. Understanding that a TSB is available for a transmission code reflash to resolve this issue, dealers are denying the repairs stating that they are unable to reproduce the issue in their limited test drives. It is not possible to predict when these severe hesitations occur, so reproducing the issue occurs on an unknown basis.
From date of purchase… when truck accelerates from dead stop, drive train shudders for several seconds before fully engaged. Suspect issue related to software, hybrid enterface with drivetrain, torque converter not locking up. Dealer verified condition with test drive. Concluded it was operating normally. I don’t buy this explanation. Is it going to fail me entering traffic? will it get progressively worse?.
