THE ENGINE COVER ASSEMBLY DETACHED FROM THE BOTTOM OF MY CAR WHILE DRIVING. SIMILAR TO THE EXISTING RECALL FOR THE FRONT LOWER BUMPER COVER ASSEMBLY. While pulling out of a parking lot, I noticed that there was a scraping noise under my car. Prior to parking at Jones Beach State Park, I was traveling on Ocean Parkway at a high rate of speed (50-60MPH) and it was a very windy day. I did not hit any obstructions or scrape the bottom of my car on anything. There was nowhere for me to pull over and as I sped up, the noise went away. When I got off the highway, the noise returned. When I got home, I looked under my car and there was a plastic piece dragging just in front of my front tires. I remembered I had received a notice about a Toyota recall related to the lower front bumper cover assembly and looked that up - it felt very similar to what I had experienced. When I got to the dealer, they told me it was not subject to the recall and the repairs on this would be $200 diagnostic plus $529.88 parts and labor. I was told I must have hit something to make it detach. I did not hit or scrape anything. My car has pretty good clearance, it would have had to be HUGE for me to hit or scrape it. I would have known.

The sun roof on this car spontaneously combusted. I was able to pull up many other complaints regarding the same issue on this car. This needs to be recalled. My [XXX] baby could have had shattered glass had we not had it closed. These sun roofs need to be recalled and inspected!

I had been driving for about 20 minutes at approximately 50-55 MPH when the check engine light came on. Seconds later, the red hybrid malfunction message displayed and I lost the ability to accelerate. I was able to pull over and I saw grayish smoke and flames coming from under the hood on the right side. I exited the vehicle and called 911. It took moments from the start to being completely engulfed in flames. Several loud pops or explosions happened during this period. The police and fire department arrived and extinguished it.

We were driving across the Texas panhandle at the posted speed limit of 75 mph. It was about noon, the outside temperature was about 60 fahrenheit & there was a cross wind of about 30 mph. There were no vehicles in front of me & the closest approaching vehicle was a good half mile away. No vehicles had recently driven past us from the approaching lane. There was a sudden explosion above us & through the 1-2" gap in the motorized retractable sunshade of our moonroof, I could see broken glass. Through that gap, some glass fragments fell in on us. I pulled over to stop, got out & inspected the roof, & the front glass panel was completely shattered & 75% gone. Many of the fragments were on the sunshade & I removed those. Going at about 40 mph we went to the closest small town where a mechanic removed some residual loose glass, vacuumed as much off the shade as he could, & patched the hole with cardboard held in place by duct tape so we could get home for a repair. If the shade had not been almost closed, we would have been showered with glass with risk of bodily & eye injury.

Driving back from lunch with a friend we heard a pop and loud shattering sound as my sunroof glass exploded for no apparent reason. I called the dealer where I purchased the car 40 days ago with every extended warranty that I could. Toyota denied the claim stating that there was not any bulletins stating material defect and that the glass was not part of any warranty and I will have to file an insurance claim.

While slowing and braking to stops (approximately less than 20 mph), the vehicle will lurch/lunge forward. It feels like you took your foot off the brake pedal but you did not. This occurs randomly. It does not happen every time. There are no warning lamps, messages, etc., prior to or during this issue. The vehicle has ~39000 miles. This has been occurring for at least 20000 miles. Risk: If this occurs when close to pedestrians, other vehicles, intersections, etc., it could result in an impact. The dealer could not reproduce but did find online message forums that reported the same issue.

The Passenger rear tire burst automatically today around 8 AM morning. Unsure if this automatic burst is part of any recall or not but it was a scary burst with big noise with no warnings of low air pressure. A lot of time was wasted today and spent money to fix a new tire.

Driver side mirror glass started shaking all the time. The mirror frame is stable, but the mirror glass is shaking when car is idling and driving. Makes it almost impossible to use that mirror when driving

my car experiences intermittent acceleration when applying the breaks. It lunges forward for some reason. It has also not stopped when hitting the breaks hard but lunges as well. I am using the last date that this happened.

Several minutes after leaving my vehicle once I parked and shut the engine routinely, it rolls back a hundred feet and crashes into another vehicle. When I come back I became aware of this as I noticed the back of the driver side of my vehicle is lodged into the side of another vehicle. This caused damage to both vehicles.

I have a 2021 Toyota Highlander XLE with a panoramic sunroof. on 5/11/2022 I was driving on the road when I heard an extremely loud explosion. I looked around and didn't see any damage, then I pulled off the road to discover that the sunroof had exploded. I called the dealership and they referred me to Safelite. Safelite took my information and called me back 2 days later to inform me that they don't stock the part I have to go to the dealer. I booked an appointment with the dealer (Sheehy), I took the vehicle in, they inspected, and I was told by Sheehy that "they've never heard of such a thing" and they were going to call the manufacturer to see if they will approve my repair under warranty. They called me back about a week later to say my claim for repair costs was denied due to, in their words "outside influences". There were no rocks, debris, etc. found that could have contributed to the moonroof shattering. Fortunately, I had the shades pulled otherwise I would have been covered in broken glass. There was no damage to the shade to indicate an object fell on it. After a quick google search, I saw that other SUV owners had experienced this same phenomenon and were told the same thing- outside influences caused this. Toyota should inform consumers about this issue and fix it no questions asked when this happens rather than try to brush it under the carpet especially when the vehicle is still under warranty. This presents a road safety issue as flying glass could get injure other people.

This is in regards to a 2021 Toyota Platinum AWD with 8500 miles. While cruising at about 40 miles/hour, the car suddenly lost power, and an alpha numeric code popped on the digital display that said -??Chip malfunction-?? and something else I don-??t recall. It also said to see your dealer immediately. On the dash, the check engine light came on with a message that said -??reduced engine power-??. This message alternated with another alpha numeric code. I did not write down the actual codes because I thought the car would record them. I was able to roll onto a side street and turn off the car. After 5 min, I restarted the car and took it to the dealer later that day. They not only could not find a code in the record, the entire trip was not recorded, even though it-??s on my Toyota app. First, they tried to say it couldn-??t have happened because it was not recorded. Then, they said the recall regarding a power issue was the culprit, but also admitted the -??fix-?? had nothing to do with, and would not affect, the engine. After insisting more be done to iD the problem and fix it, they agreed to keep the car and run a diagnostic. It turned up nothing except -??maybe bad gas-??. Really? We only use premium from reputable sources. I do not feel safe on the car and most certainly do not feel safe putting my child in it. I cannot believe they cannot find the problem.

I was driving with my daughter on the highway where all of a sudden I could here a loud noise on the top of my car. I opened the sunroof to see what's wrong only to see a Crack in the sunroof. Nothing hit the roof but it was cracked up. As I was driving it began to break up. If I had the shade opened I would have been hit with the glasses and I had my three year old in the car as well. Absolutely nothing hit the vehicle but it broke on its own.

My sunroof exploded. I reported it to Toyota USA and dropped my car off at the local Toyota dealership. We had to shut the sun shade to keep glass from falling in on us. The SUV is still in the shop and we have not heard back from them yet. I did not call the police or insurance yet. There was no warning. Nothing hit it. It just exploded.

Driver side mirror shakes when going greater than 25 mph. This does not happen on passender side, makes it more difficult to see object in mirror and more dangerous changing lanes on highways. First noticed after a few months of minimal driving.

While driving a piece popped off of the passenger door mirror. It flew off and hit the passenger door causing scuff marks before flying into traffic and causing the car behind me to swerve in traffic to avoid it from hitting their car or driving over it, which could have caused an accident. I wasn't able to recover the piece due to the incident occurring on the interstate. I did take the vehicle to the dealership (Serra Toyota - Birmingham, AL) in July and was told by the service technician that they had three other cars to come in with the same issue within the last month. Also, I was told that the entire mirror would have to be replaced since the manufacturer didn't make the piece alone. I was told that it would cost me $800 to replace the entire mirror. I should not be responsible for a faulty piece on the vehicle that was just purchased at the end of April. The technician told me that he would put in a ticket with the manufacturer, but I have not received a response.

The fixed moonroof appears to have exploded on its own while parked. No alarm was set off and no objects were found inside the vehicle suggesting an impact. There was no debris around the car. There were no storms or the vehicle is not parked near trees or ball fields. Dealer denies any known occurrence and states this must be from an impact and is not covered by warranty.
