2024 Toyota Tundra

When at a complete stop, going to pull out, or continue driving, there is a noticable lag to the acceleration. It sometimes does nothing for a few seconds before acceleration. If backing up, then switching to drive,.there is a delay and or a small jerk motion before the vehicle accelerates. This has caused issues when pulling out and vehicles are coming at normal speeds with plenty of time to pull out. The delay has almost caused several accidents.

I have had an issue several times which nearly resulted in a traffic accident. The truck has a sudden loss of acceleration where the gas pedal is completely dead. It last a few seconds and then goes back to normal. This has nearly caused several accidents where I could not properly accelerate while traffic was heading in my direction. After talking with other Tundra owners, I am not the only one with this issue. This needs immediate attention. If it is not fixed as soon as possible, I fear that someone will get seriously injured or killed. Please take this matter seriously. I suspect it may have something to do with the pre collision sensor system on the truck. It seems that it happens when there is a slight grade or dip in the road. Perhaps the sensors are at a lower angle due to the dip, making it think there is an object it will hit. The Toyota service centers don’t appear to know why this is happening and cannot reproduce the issue in a short visit.

On Sunday November 30th, I was driving my 2024 Tundra with 30k miles on highway AZ-260 on my way back home to Phoenix. The stretch between Forest Lakes and Payson has an altitude drop of 2500 feet with many areas having a 7% drop. During this drive, my engine shut down with no warning while I was going 65 MPH on a mountain highway with a 7% decline in altitude. The truck had 5 people in it with no power brakes, no engine and going 65 MPH downhill. There was no warning at all. We were able to stop at a safe spot and called a tow truck. The engine started making a loud clanking noise. We had to arrange a ride for all five of us from Payson to Phoenix (~100 miles). This was a very scary situation and it left us shaken. This could have been catastrophic for an inexperienced driver. The truck is currently at AutoNation Toyota Tempe. It has been there for 5 weeks. The dealership told me it needed a new engine. I have now received the official letter mailed to me about the recall. I also called Toyota Corporate and they told me a remedy is not yet available. Not sure how long this is going to take for it to be resolved, but its very frustrating purchasing a new vehicle and having this issue. Any help would be appreciated. The Tundra is still under the factory warranty, plus I also purchased the Toyota extended warranty and Toyota maintenance package.

Component: Electrical Harness + Vehicle Shakiness Problem: Car would enter LIMP mode randomly and shut the car down to 18 MPH and can cause accidents anywhere, especially in highway where speed limits are 65+. Car also now starts shaking violently when 48 MPH is reached which is a safety concern. Reproduce: First turn taking into dealer they found issue then “disappeared” and they could not reproduce, went in again and they produced it then said that I tried tampering the engine then got corporate involved and they paid all of it. Now they are ghosting me and will not check out the shakiness. Inspected: Only by Summit Toyota Dealership (Akron Ohio) Warning Lamps: Only appeared after issue happened and disappeared when first issue was solved.

When coming to a stop and then trying to accelerate to turn into a street I get an abnormal amount of throttle lag. There’s even times it seems to lag and then registers that I am trying to accelerate quickly causing me to “burn out” while I’m turning and no I am not accelerating crazy. There’s been a few close calls where I almost lose control of the vehicle.

When slowing down to a stop but not stopping completely then speeding up to enter another street or an intersection there is a 1-2 second hesitation before the truck reacts and actually moves. This is very scary and dangerous as it can cause an accident with oncoming traffic in certain situations. Toyota knows about this and does not have a fix for this defect.
