Assist Problems of Toyota Highlander

I was in an accident on 4/30/2024 on a casino centre way in elizabeth, indiana in front of the casino. They changed a two lane road into a one lane road by using mobile traffic lights. As I tried to brake, the car sped up and the car auto corrected in the lane on the left when I tried to avoid the impact by going right. When I crashed into the other vehicle, my air bags did not deploy. I hurt my back, neck, and chest(from the seatbelt/impact). I had no choice or option to avoid impact. On my left was oncoming traffic. To my right was the river. In the front of me, was the other car. I wore my seatbelt until the 911 operator told me to get out of the car to check on the other driver who said he was fine. The vehicle is a total loss. My insurance company, usaa, is in the process of giving me a settlement. I released the car to them.

Engine intermittently has no power on take off and causes an unsafe condition to turning into traffic where car will just not go until after flooring it and a 3-5 second delay!! engine also looses power and bucks or misses while accelerating through gears. This has caused multiple near miss incidents when turning into or across traffic. Also have issues with the steering assist that it yanks the wheel intermittantly. This cause me to loose control on the wet interstate in a turn when it yanked the wheel to the right while banking left at 65mph. I panicked and pulled the wheel back which cause a skid. The system has been turned off since. Toyota is not doing anything to repair anything and keep giving me the car back saying its fine.

The steering technology in this vehicle reads lines on the road that are not correct or valid lanes and almost caused several accidents during the 2 years I had the vehicle. Luckily, I was paying attention and had to jerk the wheel to the correct lane but the steering wheel will force itself to the other false lane. This is extremely dangerous and this is a huge safety issue.

When I am using the brakes an a medium rate the vehicle will loose its brakes for a second causing a loss of control on the vehicle. This happens randomly and caused us to almost go off a culvert of a driveway once. It has scared us many times to thinking we were going to hit the car in front of us. It makes my wife sick every time it happens. Smart motors and regional techs from Toyota have looked into this issue and determined this to be a “feeling” and not a safety hazard. This is not the case and needs to be fixed before someone gets hurt. Lane keeping assist is unusable. When it is turned on it fights with the driver. It will swerve back in forth in its lane and sometimes so bad it feels like the car would roll if it was not turned off and got worse. Every once in a while it will try to take an exit on the highway by itself. Date of incident in questionnaire is approx to the last time it happened. It has happened too many times to count. Vehicle mileage is when we first started really having issues with the brakes. Lane assist is an always thing.

The system designed to prevent lane departure has a particular issue with the dashed road markings that denote the entrance to tapered deceleration lanes or right-hand exit ramps on oregon freeways. I have not noticed an issue when similar markings are on the driver's side. . Read more...

Vehicle constantly drift to the left which make it very unsafe because the driver is in a continuous correction mode to remain in one lane - can inspect anytime, alignment and tire rotation has been complied with at least 8 times within the last 3 months by Toyota dealer and firestone conclusion alignment is ok sometimes with minor correction. I'm constantly holding pressure on the steering to the right and left to remain in my lane doesn't matter about the road. The problem is worst on multi - lanes in the same direction with tractor trailers passing due to air current.

The lane keeping assist does not work properly on my vehicle. The lane keeping assist does not keep my car in the center of the lane as intended. For instance, it very forcefully makes the car drift to the left and right of the lane and frequently pulls it into the other lane. I have reported this to my local dealership - sparks Toyota in myrtle beach, SC and Toyota corporate. Sparks Toyota service has admitted that there are many customer complaints about this issue. They have stated that there is a software download "fix" in the works, but not yet available. I did not take their word for this and called Toyota corporate. The only "solution" I have been offered is an offer to show me how to turn the feature off. This is totally unacceptable as the is an important safety feature that does not work properly and in fact, creates an unsafe situation while driving. Since my report of the issue, I have been made aware of an owners facebook forum that other owners state they are having the same issue and seems to be a widespread problem.
