| Vehicle Speed Control problems |
What component or system failed or malfunctioned, and is it available for inspection upon request? the electronic throttle control system (drive-by-wire) and transmission control module (tcm) calibration. When accelerating from rolling stops or yields (0–10 mph), the vehicle experiences a severe dead-pedal delay with zero engine or transmission response for 1. 5 to 2. 5 seconds before surging forward. The unmodified vehicle is fully available for inspection. How was your safety or the safety of others put at risk? the failure creates an immediate crash hazard during left turns across traffic, entering roundabouts, and yielding into highway merges. Pressing the accelerator to merge into traffic produces no acceleration, leaving the truck stranded across active travel lanes. Approaching cross-traffic must brake aggressively to prevent broadside/t-bone collisions. The unpredictable delay followed by an abrupt power surge severely impairs low-speed vehicle control. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. An authorized Toyota dealership service department test-drove the vehicle and confirmed the low-speed hesitation/dead pedal. The dealer stated no fix or calibration exists for this model year because the vehicle has the latest factory tcm software (prior tsbs do not apply) and designated it an "inherent operational characteristic. " has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes, inspected and diagnostic-scanned by certified technicians at an authorized Toyota dealer. No dtc codes were stored; the failure is in the factory throttle logic and transmission management calibration. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warning lamps, dash alerts, or trouble codes appeared. The symptom presented immediately at initial delivery and recurs consistently in all modes.
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.
After stopping at a stop sign and waiting for a clearance, the truck did not respond to throttle input for what felt like 2-3 seconds. The temperature was about 80 degrees, and I had already been driving for 30 minutes when this happened.
There is an inconsistent lag in the response from the accelerator. It proves to be extremely unsafe when it occurs while trying to join traffic or cross traffic. A few times now this lag has nearly caused an accident where my vehicle would have been t-boned if the oncoming vehicle hadn't slowed down quickly.
