There are 19 owner-reported speed control & cruise complaints for the 2023 Toyota Tundrain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Throttle response is unpredictable. From a stop sign, acceleration is difficult to predict. Sometimes a one second delay occures before acceleration power is effected. With the time delay the throttle has been pressed further than normal. In heavy traffic, a collision could be possible. The problem got worse after a firmware update, during a safety recall to replace rearview touch screen. Pedal Lag problem is noted on Toyota Tundra forum.
There have been multiple times, since owning the vehicle, when there is dangerous throttle lag. I step on the gas to turn and nothing happens for a few seconds. It can be pretty scary when there is a car coming and the truck just rolls for a few minutes before accelerating. It’s become a major safety concern for my family.
While pulling out into traffic, my truck will suddenly hesitate. It also caused a vehicle to hit me as the truck pulled out into the lane, then suddenly completely lost power. Dealer was unable to replicate. Has happened to me several times when at a stop light. This is slightly safer as traffic behind me is stopped or slowed. It feels like a throttle issue as it completely looses power
I get random lags in thorttle engagement when starting from complete or rolling stops. When this happens, it behaves like there is a delay between the throttle input and the engine resoponse. Push the throttle to go, and no go, and after a delay of usually part of a second, then it jerks and goes. Most times there is no problem and the throttle responds correctly, but this issue occurs randomly almost every time I drive.
After coming to a stop and then trying to accelerate, I experienced a lag or throttle hesitation when trying to accelerate again. After pushing the pedal, nothing happens, then all of a sudden it accelerates abruptly.
Unknown. Intermittently when merging into highway traffic from the onramp, the truck will stall and I will lose acceleration. There will be a loss in power and the truck speed will not change. instead it will just coast with no ability to change speed. I have owned the truck for 1 year and 3months. I advised the dealer and they can not duplicate the issue.
THROTTLE LAG/LURCHING: When pressing the gas pedal at a full stop or pulling into traffic on the expressway the truck hesitates. it doesn't immediately go. This happens often...Transmission should be recalled. IT'S VERY DANGEROUS ESPECIALLY WHEN PULLING INTO TRAFFIC ON THE EXPRESSWAY
The vehicle inconsistently delays when accelerating from a stopped position. This is more frequently noticed shortly after starting the vehicle. This was first noticed around 10K miles, and my vehicle is currently at 25,235 miles. This has happened approximately 4-5 times. While at a stop sign, judging traffic to enter into the intersection I have pushed the gas with no response for 2-3 seconds then a sudden burst of power. Having worked as a state LEO/Trooper for over 25 years I find this very concerning. Any delay in acceleration for power could result in a collision.
The vehicle has a hesitation when accelerating or when I turn a corner and then try to accelerate it lags. Had a few incidents where I almost got rear ended due to the issue
Truck will have a very bad hesitation when coming to a stop and trying to accelerate again before a complete stop. Many times this has almost got me into an accident when trying to pull out into traffic. You will push the gas and there in a 2-3 second delay before the truck will even move. This often makes it a very close call if you’re not expecting it.
Sometimes my truck hesitates from leaving a complete stop. I will press on the accelerator and there is throttle lag response, which causes me to pull out slower than expected. There was one time where I pulled out and lost throttle power in traffic. I have taken it to the dealer and reported this Issue. They flashed the ECU and said that was the only fix they had, but it didn’t do much difference I still experienced the throttle lag from a dead stop.
When at a 2 way stop sign, for example, I am fully stopped, foot on the break, I see that there is a break in the cross traffic that indicates that I am safe to cross. I hit the gas and the car does not move for a few seconds. By now the car has me in danger and the other drivers who are coming towards me in the cross traffic. I count on the car to go when I hit the gas, especially when trying to get across a busy street or accelerating from a stop to merge into moving traffic. When the car does not move for a few seconds after hitting the gas, I’ve now been put in danger and have caused a disruption in the flow of traffic as well as putting others in danger. No lights on the dash indicate an issue, the truck is in normal mode, and I have not had this confirmed by a dealer yet, but I’ve read many testimonials from other 2023 tundra drivers having the same issue.
Lag in acceleration. Press the accelerator and vehicle takes a few seconds to respond. Trying to right turn on intersection and due to acceleration lag almost got hit by another vehicle. The accelerator should respond immediately when pressed just like it does on all the other vehicles I have driven. This has happened on multiple occasions with this vehicle.
Hesitation from a stop. Vehicle isn’t following pedal input and at times can put me into a side collision. Lane keep assist is dangerous and throws me off the road constantly. At times the lane assist will fight my input at the wheel and pull me off-road and over the lines.
When attempting to accelerate, the vehicle idles down and fails to accelerate for a period of 2-3 seconds. To initiate normal acceleration, fully depressing the accelerator pedal is required vs. a gradual depression of the pedal.
The issue is with the auto-braking or pre collision system. Have had multiple instances where system has engaged at low speed which also engaged the auto engine stop feature when it was not necessary. Have noticed system engages on roads with curves where it thinks the vehicle in the other lane is in front of me when its not. The most unsafe thing that happened was when a vehicle quickly changed lanes in front of me and slowed slightly. I saw the other vehicle make the unsafe lane change and was covering the brake and when i pressed the brake it went out from under my foot braking hard on its own when it was not necessary. Vehicle slowed from 65 to about 35 quickly almost causing vehicle behind me to rear end me with no way to stop the system. Since i have owned this vehicle auto brake system has engaged about 5 times and all were not necessary or unsafe. I have lowered sensitivity setting and still have the issue, and am unable to disable system.
In some cases when slowing down to a very low speed an trying to to accelerate again. There can be either a brief (1/2 second) or a very long ( > 1/2 second) delay between pressing the accelerator and the engine responding. Because of this delay its very hard to gauge when and how the vehicle will respond. In some conditions this can be a safety concern as the vehicle behaves unpredictably. I was able to verify this with engine logging data the data shows that the computer acknowledges the accelerator position but fails to advance the throttle or by any means add power for a period of time and then behaves in a expected manner after a delay between 1/2 to 1 second. The best I can gather the problem happens in a timing window when the transmission shifts from a higher gear to 1st gear. I took into the dealer who also verified the concern and opened a TAS case with Toyota. TAS took my data but provided no information or guidance to the dealership.
1. There is some sort of severe throttle lag/takeoff issue that happens intermittently, but almost always several times a day. always from a stopped position. 2.When you are turning left (going across the oncoming lane) you hit the gas pedal and nothing happens for 2-3 seconds and then it shoots off like a rocket ship. I have never been so close to a severely injured or more likely fatal car crash. this severity has happened twice, once with my daughter in the car. 3. Not yet. looks like there had almost been a class action law suit back to 2022 model year (same engine I believe). 4. No 5. No warning lights ever. as stated this is going back to 2022 and i haven’t visited a dealer yet as they tell the owners (there is no fix for the issue). hoping this forum can make a difference.
The contact owns a 2023 Toyota Tundra. The contact stated that when the accelerator pedal was depressed, the vehicle failed to respond. After the accelerator pedal was depressed to the floorboard, the vehicle responded. There were no warning lights illuminated. The vehicle was taken to the local dealer, who test drove the vehicle but was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The vehicle was taken to another local dealer, Joseph Airport Toyota (1180 W National Rd., Vandalia, OH 45377) who was unable to duplicate the failure after a test drive. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 21,000. The VIN was not available. The contact stated that the manufacturer representative will not offer any more assistance if the vehicle does not experience a hard failure. The vehicle is currently not in use.
