Toyota Tundra adaptive cruise problems

Filed Sep 23, 2026 · Driver assistance, Steering · GA

When using the cruise control and lane keeping system the truck will jerk into oncoming traffic and try to swerve off to turning lanes. I took it to Toyota and they couldn't find any problem. no warning lights or any indication of a problem shows on the dash. At this point the system is unusable. I have seen many post of similar incidents on the internet.

On September 1, 2026, my 2022 Toyota Tundra experienced a serious loss of accelerator response while I was leaving a gas station and entering traffic. I pressed the accelerator, but the truck provided effectively no acceleration, leaving me partially in the roadway. An approaching vehicle had to swerve into the opposing traffic lane to avoid a collision. I had experienced a similar low-speed loss of accelerator response within the prior two weeks. On September 2, while traveling on I-70 at approximately 70 mph, the truck experienced a separate loss-of-power event. Engine RPM dropped considerably and the vehicle felt as though it were coasting. I pressed the accelerator firmly, but it did not respond normally for approximately 5-10 seconds before power returned. Radar/adaptive cruise control was not engaged. I immediately took the truck to Western Slope Toyota. Technicians checked for codes, performed multiple road tests and recorded vehicle data but could not reproduce the intermittent failure. The issue was escalated to Toyota technical assistance under TAS Case 262460664. This problem has been documented by Western Slope Toyota since 2023. Toyota's applicable TSB repairs were performed on prior occasions in an attempt to correct the throttle/hesitation problem, but they did not resolve it. In 2025, the dealer again documented the condition after the earlier TSB had already been performed. According to the September 2026 repair documentation and my discussion with the Western Slope Toyota service manager, Toyota's specialist technical team is aware that the condition can remain despite the TSB work. The repair order states that Toyota identified a known hesitation concern that remains under investigation and that there was no repair to be made at that time. The condition is intermittent and unpredictable and can cause loss of accelerator response or motive power at low and highway speeds. I believe it creates a serious crash risk. Current mileage: 58,735.

Between the hours of 11:00 a.m. and 1:00 p.m. while heading west with cruise control on and I passed a truck that was fully in the left turn lane my vehicle has done a collision avoidance complete stop three time in the same day. I wasn’t tailgating and I was doing the speed limit of 55 mph. The road was very straight. It did this twice before about a year ago. I reported it to the dealer and they could find nothing wrong with my vehicle.

When starting up my truck in the morning there is rough idle that cause truck to sputter and sound horrible. It eventually smooths out but I believe the computer needs flashing. When I look online some have a recall for the engine 3UR-FBE / 2018 Toyota tundra, but when I put in my vin # it shows no recall and throws off check engine light Code. Also my radar sensor that it on for cruise control is showing up on dash please contact dealer and flashing. They have replaced this before with recall and now it’s acting up again. Also traction control is lighting up I. The dash as well blinking along with all these codes.

Ive been noticing a significant lag sometimes when I press the gas pedal. It last just a couple seconds. This could possibly become something bigger. Will update of it gets worse. Also the cruise control doesn't hold the set speed it stays 1 or 2 miles under.

WhenThe truck is on cruise control and there is a need to pass a vehicle in the freeway; I lightly accelerate push the pedal then there is no response ( the vehicle hesitates for a second or two) ; and suddenly the engine revs up (and jerks the truck) and slams the transmission to start accelerating. I looked up this issue and realized that may be a common issue. this has happened in several occasions since I bought the truck last year, I drive my truck very carefully. I will bring this issue to the attention of the dealer.

There are two recurring issues effecting my truck. These have been ongoing for 6 months, since March of this year. I have been to my dealer Lum's in Warrenton, Oregon 8 times for this. They have been unavailable to fix the issues and told me they needed a Toyota factory person to fix the issues because they do not have anyone at the dealership that can do it. Nate Whisnant, the service manger at Lum's was suppose to make this happen but he has not. They are not responding. I have sent a request to my sales person Liz Valsqueze try to get some movement from Lum's. These issues are described by my Launch code reading tool, which I had to buy to clear the codes to keep my truck operational as designed. The issues are two issues for the Power system: 1. P2450 7E 2. Evaporative Emissions System Switching Valve Actuator Stuck On There are two issues for Vehicle Body System: 1. Evaporative Emission System Switching Vlave Performance/Stuck Open 2. Lost Communication with Image Processing Module "B" Missing Message Effectively what this means is that: 1. The truck throws a check engine light and asks me to contact the dealer while simultaneously disabling ALL cruise control related functions. 2. The Cameras used for parking, backing, checking the security of loads i the bed etc are all disabled. All camera's around the truck are disabled not allowing for safety checks when pulling into or out of parking, etc. It is unsafe not to have a view around my truck when pulling in and out of tight places. It it unsafe not to have fatigue reducing cruise control on long trips and in heavy traffic with collision braking assistance that does not work. This vehicle is available for inspection by anyone that will take the time to inspect it. The is a constant warning lamp that does not go off asking me to contact the dealer to fix it. These warning lamps first appeared in February 2024. I purchased the truck in December 2023. The dealer has not fixed the problems.

I backed out of my drive way and then proceeded to the stop sign at the end of my street which is three houses from mine. Turned left off of [XXX] onto [XXX] I started to accelerate to speed limit which is 25. I then looked at speedometer it stated I was going 15 mph then all of a sudden my truck accelerated to almost 69 mph then my truck slammed in the brakes. My foot was still on the gas petal and I never felt the gas petal push down when it accelerated. No my cruise control was not activated and no lights came on to indicate what it was doing or that there was anything wrong. Steve’s Hometown Toyota could not find anything wrong with the truck, but then again I don’t trust them I gave them a month to get the guy to fix it and the part and the loaner to fix the canister on my Highlander but when my appointment came up the guy couldn’t stay the full 5 hours to fix my car and they did not have a loaner and did not have the part. That is how I got into the 2023Toyota Tundra. Then it develops a brain that it wants to go faster then slammed on the breaks. That truck hurt me and gave me whiplash. They want me to pick it up. I am not driving it. I am lucky no one was in the truck and on the road the time the incident happened. I have made a report to Toyota and let them know that I have doctors notes and my daughter was on the phone with me through the truck not on my phone. I am afraid that they are going to put me back into the same truck that hurt me. Know I find out that the 2023 trucks have a recall on them. They still don’t have an answer for me. What if they put me in another Toyota truck what if they have the same problems. I used to have faith in Toyotas but now I don’t. It hurt me and I am still having issues from that stupid truck.
