Filed Sep 30, 2026 · Transmission · TX · crash

On September 23, 2026, at approximately 7:30 AM, I was driving the vehicle in a parking garage at an estimated speed of approximately 10 mph. While driving over a curve in the parking garage and applying the brakes to slow the vehicle and maneuver into a parking space, the vehicle suddenly accelerated on its own despite the brakes being applied. The vehicle struck the metal wire safety fence and then came to a stop. Prior to this incident, over the preceding 2–3 months, I had experienced intermittent problems with the transmission. Specifically, when shifting from neutral to reverse, the transmission would occasionally become temporarily stuck or fail to engage properly. It would then begin functioning after a small tap. What component or system failed or malfunctioned, and is it available for inspection upon request? : Possibly transmission How was your safety or the safety of others put at risk? There was no one else in the parking garage as it was early in the morning, otherwise it could have resulted in loss of additional property and possibly injuries. Has the problem been reproduced or confirmed by a dealer or independent service center? Going to consult with the dealer soon Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? insurance has been informed. Awaiting their response. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? As mentioned about 2-3 months prior there were minor transmission issues.

When I am slowing down and coming to a stop, my car will surge forward. It feels like my brakes stop working for a second and that I pressed the accelerator. It has happened on flat road, hills and turns.

I reported twice to Tustin Toyota that my car seemed to have a strange braking issue. It felt like the car lurched/lunged forward as I was braking. Every time I brought it into service, I verbally mentioned it to the technician checking my vehicle in. I was repeatedly told there was no issue. Turns out there is an active bulletin (T-SB-0059-23) that came out but now my vehicle is out of warranty and they won't fix it unless I pay out of pocket. Why was the dealership not aware. Why is this not a recall for all affected years regardless of warranty? There have been multiple reports online with people have the same issue.

As my wife had the wheels turned and was pulling up to the curb stop in a parking spot the car suddenly lurched forward without putting the accelerator on and went up and over the curb. Stop and hit a pole. my thoughts are is that the engine possibly changed from hybrid to gas or vice versa and as my wife’s foot was let off on the brake to inch forward to the curb stop it suddenly lunged forward as previously stated.

The brake system on the 2022 Toyota Highlander Hybrid malfunctioned momentarily this weekend (7/8/23 was date of incident) in North Kington, RI. While coming to a gradual stop at a stop light, the brakes momentarily stopped working and felt like the car lunged forward before the auto braking system activated since there was a stopped vehicle in front of us. My foot was on the brake pedal but the brakes just stopped working for a moment. I've read in other toyota forums that this has happened to others with 2022 hybrid highlander models. The same issue happens when applying the brakes going down hill and going over a bump. I'm bringing the vehicle to the toyota dealer this week. No warning lights ahead of the problem.

1. The engine was on while the 'hold' feature was enabled. I've used this feature numerous times before. This time, the 'hold' feature was on for about 5+ minutes, I heard 3 consecutive beeps out of nowhere followed by the engine restarting on it's own as if the push start button was pressed. At that time, the vehicle lunged forward causing me to brake, missing the vehicle in front of me. This happened while waiting at the school drop off lane. Vehicle also lags during acceleration and stalls especially when getting up to speed on the freeway/highway. 2. My children and I could have rear ended the vehicle in front of us which in turn, could have caused a chain reaction with thr vehicles all in front of us (at least 15+ vehicles before mine). We could have been seriously injured, families / staff walking in and out of the parking lot could have been hurt. Regarding the acceleration lag and stalling, we could potentially be at risk of getting hit waiting for the vehicle to pick up speed. 3. My vehicle is at the dealership currently, waiting to hear back from them as there are other numerous reoccurring issues with this vehicle which the dealership I purchased from failed to fix three times prior. 4. The issues have only been 'looked' by the dealership only. The initial dealership failed to have the Regional Engineer come onsite to investigate. I was told my issues were non concerning. 5. Regarding the vehicle lunging, in that instance, the only warning were the three consecutive beeps, no error lights or errors were observed. Regarding acceleration problems, there are no errors or sounds indicating problems thus far when the issue takes place. I have a list documenting the various issues I have experienced thus far with the first problem starting after owning the vehicle for about 3 months.
