Yesterday, as I do a couple times a month, I went to switch parking places, putting my 2021 Toyota Highlander where my 2007 Mazda was parked, in order to drive it and keep the battery from dying. After starting both cars I first moved the Mazda to make room for the Toyota. As I was slowly steering the Toyota at (idle speed) into the now vacant parking spot, the car accelerated on it's own, prompting me to hit the brakes, but to no avail. The car jumped the curb hitting, knocking over and and damaging a large ceramic planter and small tree in my neighbor's yard. My split second reaction upon having no brakes and a run away car was to push it out of drive, which ended up putting the car into reverse, causing a harsh jolt, followed by the car accelerating again on it's own, in reverse towards another neighbor's garage. I live in a condo complex, so all of this took place within about 30 feet of forward/backward/forward motion. My second split second decision (with no brakes) to avoid smashing into the garage was throwing it back into drive, which sent it accelerating back towards the parking place again. This time I had the presence of mind to push the power button on the dash, allowing me to barely come to stop before jumping the curb again. Whole thing lasted about 15 seconds. I had an appointment to attend, so after a brief conversation explaining to my (now outside) neighbor what happened, I left in the older car. Returning later in the day I found damage to the front of my Toyota and wonder if my transmission is damaged as well. I'm reimbursing my neighbor today. I've not attempted to drive the Toyota since, and am seeking your advice on how best to proceed, whether I should initiate contact with Toyota regarding this incident, or is that something you should initiate? Please advise. Thank you.

The Check Engine light came on and I took it into Toyota of Downtown dealership where I was receiving periodic maintenance. After 2 days, they said the light was out but they hadn't found the cause. I could either leave if for a few more days or take it and bring it back if the light came on again. This was early August. I chose to take the car & when the Check Engine warning light came on again, I took it in on Aug 15, 2024 before I left to Portland to give them more time. I returned on Monday & couldn't reach them. The next day they informed me that while on a test drive, there was a loud bang, it started smoking and by the time 911 arrived it was on fire. After a 2 month investigation by Toyota's Engineering Analysis fire inspection, they concluded Toyota was not involved. The dealership has not provided me with the report although I've requested it but they aren't accepting responsibility either although it was in their possession when the fire occurred.

Upon attempting to engage the brakes, it was found that they did not work. Immediately thereafter, the car began an uncommanded full acceleration. The insurance company has totaled the car. Our safety as occupants was obviously at serious risk. The driver chose to take the car off the road rather than jeopardize the lives of others on the same road. The car plowed through boulders and trees, coming to rest upside down wedged between an earthen berm and a tree......suspended about 2 feet above the ground. There were no warnings prior to the incident. The car has been inspected by the insurance company, and has been authorized for inspection by the manufacturer. There were no serious injuries as a result of the accident. We were VERY lucky! Uncommanded acceleration without any control is a frightening event any time....but definitely in the vicinity of other vehicles full of families.
