2025 TOYOTA TUNDRA Vehicle Speed Control Problems

Throttle lag, was stopped at a stop sign and had an opening to go, when I pressed on the gas the truck went as normal and then completely stopped accelerating. By the time it accelerated again it jolted the truck and was narrowly missed by cross traffic.

Throttle lag truck stalls out when you try to go from a stop. It will cause an accident if this is not fixed. Also engines keep blowing up with out the hybrid system your truck will not have any port to get over to a safe spot on the road. Toyota is replacing engines but the ones they are putting in the trucks are the same ones that are failing.

The vehicle does not predictably respond to throttle inputs (if it responds at all), when you come off the brake pedal it will begin rolling at "idle" speed as normal but when you begin to increase throttle input NOTHING will happen for several very important seconds as you roll into an intersection or need the vehicle to accelerate to maneuver. This had happened multiple times before scheduling service appointments. The day BEFORE my appointment while trying to make a right hand turn from EB 13st St in Lemont IL to SB Bell Rd, i had stopped for the red light, verified clearance to make the turn, and began my maneuver. Once I came off the brake pedal the vehicle began to roll into the intersection but as I began to turn the vehicle and try to accelerate though the turn it did not respond WHATSOEVER. I desperately tried to roll my vehicle into the ditch to make space the incoming vehicles to minimize danger, but had no power to do so and was violently T-boned. The vehicle was brought to the dealer for their analysis, the service manager initially claimed "I know exactly what it is" and continued to ask questions that prompted previous knowledge of this issue including what speeds and conditions it will occur at.. two weeks later the vehicle is "ready" and the manager claims the "eprom" had 2 pages of codes in it and that "got rid of the hesitation" I take him for a test drive with me and was able to recreate the issue a few times at which point he said "i understand your frustration with the truck but its a GOOD TRUCK" I drove the truck a few days and continued to experience dangerous and unpredictable delays in throttle response, one of which almost caused me to be rear-ended by a semi while merging from IL-rt83 onto I-55 nb The vehicle has been left behind on a family road trip as it is not safe enough for my family. In hind sight I wish I had the opportunity to submit it to NHTSA for examination after the crash rather than than Toyota. PLEASE DO SOMeTHING

Stopped at a stop sign at an intersection. Intersection is 4-way, with only a 2-way stop. After ensuring cross-traffic was clear, initiated a left turn from being stopped at the stop sign. Released the brake pedal and began to accelerate.Truck only accelerated to 5mph, and then began to roll/drift into the intersection with no power. No response from gas pedal. Drifted into intersection and was nearly struck by an oncoming vehicle. Accelerator finally responded, lagged once more when attempting to accelerate quickly to get out of the intersection, and then began responding appropriately. I could have been T-boned by another motorist while drifting without acceleration ability through an intersection. My foot was firmly on the gas pedal, with no response. This was only one of two occurrences of this, the truck has not been serviced by the dealer for this issue. No warning lights were displayed at the time, nor did any illuminate.

While starting to accelerate from a stop whether it is going straight or turning the truck hesitates and takes multiple seconds to start accelerating leading to a potentially dangerous situation especially when turning and you can't get out of oncoming traffics way. Also when at a slow roll trying to accelerate the truck just does not apply any power for multiple seconds delaying movement and potential to avoid an accident.

Vehicle experiences electronic throttle lag that causes the vehicle to not accelerate when pressing on the accelerator pedal. Then it accelerates excessively and nearly uncontrollably before coming under control.

On several occasions when attempting to accelerate from a complete stop, the vehicle fails to accelerate, or begins to accelerate and then ceases, leaving the vehicle partially out into incoming cross traffic. This occurs for a second or two before acceleration resumes.

Making a right turn from a stop. I pressed the accelerator and the vehicle barely moved. Cars were coming in my direction and I had to move. I let off the accelerator quickly pressed the accelerator again. The vehicle did start moving at normal rate. This first attempt was very concerning and almost caused me to get in an accident.

There is an interment issue where the vehicle fails to accelerate from a stop when accelerator is applied. This issue is present in my current vehicle and my previous 2023 tundra. I have brought up concerns to the dealer and manufacturer and am told every time that the concern cannot be duplicated, but I feel that it is going to lead to a crash not only for me but other owners

Upon starting the vehicle on 8/6/2025 i received multiple warnings: advanced ultrasonic detecting and ranging system malfunction, Pre-Collision system malfunction, Parking Brake system malfunction, Check engine ECM malfunction, Vehicle stability control system malfunction Secondary collison brake system malfunction, It now take almost a mile on level ground to reach 45 mph. This occurred without warning. the vehicle was ok the day before when I parked it.

Speedometer and associated systems and controls are inaccurate by margin of 18% (9mph @ 55 mph) Speedometer reports speed of 55 mph when truck is traveling at gps tracked speed of 64 mph. Without an accurate speed reading, it's easy to accidentally speed, especially in areas where the speed limit frequently changes. Speeding increases your stopping distance and reduces the time you have to react to unexpected events, significantly raising the risk of an accident Inaccurate Distance Tracking Your speedometer is often linked to your odometer, which tracks the distance your vehicle has traveled. A faulty speedometer can lead to inaccurate mileage readings, which might affect your vehicle's maintenance schedule. If your odometer isn't tracking miles correctly, you might miss crucial maintenance milestones like oil changes, tire rotations, or other essential services. Fuel Efficiency Issues A malfunctioning speedometer can also impact your ability to monitor and maintain fuel efficiency. Without accurate speed data, you may find it difficult to optimize your driving habits for better fuel economy. This can lead to increased fuel consumption and higher operating costs over time. Legal and Insurance Complications In the event of an accident, a faulty speedometer can create legal and insurance challenges. If you can't accurately prove your speed at the time of an incident, it could complicate the process of determining fault. This is particularly problematic in accidents where speed is a critical factor. This problem was reported to Anderson Toyota dealership and Toyota corporate customer care

Every so often there is a hesitation when I’m trying to accelerate.

2025 Toyota Tundra with 2200 miles. Truck has developed an intermittent lag/hesitation when starting from a stop. At random times, when pulling out into fast moving traffic, hit the pedal to proceed and enter the roadway and it will take a second or two before there is any response from the engine. Oncoming traffic traveling at 50mph are now a second or two closer and need to brake hard to avoid collision. There seems to be a fault between the throttle pedal and the engine. No warning lamps. Difficult to reproduce as it only happens on occasion. Vehicle has not been inspected by a dealership. The issue has been reported to Toyota via online support, message # [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lags when accelerating from a full stop. At least 1-2 seconds. Extremely dangerous. I’ve got 600 miles on a brand new truck and it’s happened twice in the last 24 hours. I was nearly T-boned.

There is significant throttle lag where the throttle has a delay in engagement after a rolling stop. Turning into traffic flat out is dangerous when the throttle has a delay, if you push harder then it gives you too much throttle after the delay and will chirp the tires. I am not the only one. 100s if not thousands of people are complaining about this same issue.
