I was forced to change lanes quickly from the left lane to the left shoulder of an interstate when a double tandem tractor trailer moved into my lane of traffic. The interstate was dry and the left shoulder was in excellent condition and wide enough to accommodate my vehicle easily. All lane assist options were turned off, the driving mode was set to -??economy-?? and the cruise control was turned to -??off-??. A few seconds after entering the left shoulder of the interstate, I felt the rear end of my vehicle sway from side to side for a few seconds. After the swaying ended, I thought there was a brief loss of vehicle control after which the vehicle returned completely to my control. My vehicle is a Toyota Highlander Limited AWD gas engine SUV with about 2700 miles when this occurred. I drove my vehicle without any emergency steering maneuvers 2700 miles prior to and 500 miles after this incident without any problems. I had my Toyota dealer examine the suspension, steering and event recorder of the vehicle and test drive it. They found the vehicle to be performing within manufacturers specifications and without any defect in the steering or suspension and found no codes found in the event recorder.

The answer to the above questions is UNKNOWN. I do not clearly remember the moments leading up to the incident. I was parked on the driveway of my daughters house. I was in my Toyota Highlander Hybrid 2021. We were stationary at the top of the driveway after returning because we had forgotten something. My grandsons were in the car but they were not hurt. The driveway is on an incline. ?I am not sure what happened from here. As I exited the car it started to roll backwards. I tried to get back in to stop it but got knocked down by the open door and moving car. I fell. The car rolled over my legs, dragged me down the incline and I was stuck under the front bumper. The car stopped either because of the ABS when I was as the front of the bumper or because it was on level ground at that point. My son-in-law tried to put the car in reverse to move it off of me but said they could not get it to start. I was barely stuck and the neighbors just lifted the front bumper a bit and I rolled out. ? I have some soft tissue damage (full thickness degloving to the bone on my left calf and 4 fractures (1 in each leg and a couple in my pelvis). I have been to the operating room 4 times, the emergency room three times and spent 19 days in the hospital. It is the first car I have had with a key fob, no physical emergency break and I have safely parked in on this driveway for 5 months. It does not make sense that it would be in neutral as I never use that gear but that seems to be what would have had to have happened for this to occur. l bought this car for all of the safety features yet this still happened so I am sharing it with you in case there are further safety features that can be developed to prevent such accidents in the future. If it had a real key and real emergency brake I do not think this would have happened.

The car was stopped at a red light and the car shook and slightly vibrated and shut off. No warning signs, no warning lights, just died. I was in the car with my twin 3 year olds, the AC shut off, everything shut off, the temperature outside was over 90 degrees and heavy traffic. I was very scared for my safety and very confused as to why a brand new car would die.

About 15 minutes prior to the incident, the interior shade cover was closed beneath the moonroof. Mostly sunny day about 85? F, about 55mph, the moonroof exploded. The sound was that of a shotgun, followed by wind noise and tinkling noises of shattered glass just beyond the shade cover. Upon external examination, 100% of the glass sliding moonroof was shattered, approximately 30% of the glass had departed the vehicle from a forward and central portion of the glass area. The remaining glass was bowed outward. The roof aft of the moonroof displayed 1-3 millimeter length flags of clear coat paint where the glass shards had etched the painted surface and the rear spoiler fairing panel over the aft hatch had gouges in the plastic composition along the upper surface of said fairing. All components on the vehicle were factory installed. Vehicle had 10,000 miles and was in service just over 5 months. There were no indications of an impeding problem. The moonroof was secured with tape and cardboard to prevent shards of glass from departing the vehicle. The dealership body shop estimates repairs at $4319. Safety threat: If shade were open at the time of explosive incident, shards of glass would fall onto driver and passengers, which might create a loss of control from panic (explosion was very loud and disconcerting) glass in facial area (between eyes and sunglasses) or falling into clothing at the neck area and creating a painful bloody situation at highway speeds. Shards of glass departing incident vehicle might reach a following vehicle (motorcyclist) depending upon upward trajectory of glass and forward speed. Might affect vehicles traveling in opposite direction. Driver following incident with window down might be exposed to shards of glass slip streaming into that vehicle.

I purchased my Toyota Highlander Hybrid only about 2 months ago. Since then, I've experienced several incidences of sudden acceleration. In a few of them, I was approaching a stop sign and began to slow down. Suddenly, I felt the car accelerate on its own. In both instances, I slammed on the brakes and the car jerked then stopped. There was one instance when I was going down hill and I was stepping on the brakes, but the car seemed to accelerate on its own until I stepped on the brakes again. Fortunately, there were no collisions. However, this is a serious safety problem.
