While driving at approximately 45 MPH on a multi-lane parkway in Virginia, my wife and I heard a loud explosion which I immediately assumed might be a tire blowout. However, the steering system seemed normal as I slowed the car and began a move toward the road's shoulder. Within 10-15 seconds we began to hear the sound of "rushing air" above our heads. To determine why we heard that sound we slowly retracted the interior cabin fabric "head cover" to expose our sunroof; as soon as the "head cover" had retracted an inch or two it was clear that we had a large hole in the sunroof forward panel and that the tempered glass had shattered. We immediately closed the "head cover" and continued forward to our home which was a few miles away. As we drove, more and more "glass shards" were falling to the topside of our head cover. Fortunately, with our fabric head cover closed when the sunroof "failed" we were not showered by glass. However, had we had the sunroof exposed, I believe we would have had small glass pieces fall into the cabin area and on our heads. I have called my insurance company (USAA) and they have processed my claim sending me to SAFELITE which in turn has forwarded my repair work to SUNROOF EXPRESS. I called my Toyota Dealership which told me the sunroof is no longer under warranty. I can only speculate that the failure was caused either by a "micro-defect" in the sunroof which over time and temperature changes (summer heat, interior cool from A/C, winter freeze, etc) caused a sudden failure; or, it's possible a rock/pebble kicked up by a vehicle somewhere in front of us had a trajectory high enough (higher than our front windshield) and then impacted the sunroof at a sufficient angle to cause its failure. Following this incident with my car, I went on-line and discovered that I'm not alone. Apparently many other motorists have experienced what they describe as "explosive" sunroof failures...and some have been showered in glass. Not good!
I have experienced brake issues, on any slight decline where the braking system will let up as if the braking is not working for a moment, and also, a jerk forward once stopped. This will lead to an accident and potentially, a pedestrian getting hurt if not addressed. I took it to the dealer and they stated they could not repl…

I have experienced brake issues, on any slight decline where the braking system will let up as if the braking is not working for a moment, and also, a jerk forward once stopped. This will lead to an accident and potentially, a pedestrian getting hurt if not addressed. I took it to the dealer and they stated they could not replicate the issue, therefore, did not run diagnostics on the vehicle and will do nothing else for me. I have great concern this will lead to an accident and after 30 years of driving, I'm having to constantly think of leaving enough room between myself and other cars to avoid an accident, and adequate room for a brake malfunction. I have another 2020 hybrid Toyota that does not have this issue. So, it is not an issue with all hybrids.

Excessive tire wear was noted at 18,000 miles requirement replacement of tires. 25,000 miles later, the same tire wear problem has occurred on a set of tires rated at 65,000 miles. The west is much more predominant on the passengers side. Toyota has been informed and claims there is no problem with the vehicle, despite not inspecting the vehicle for other causes. This is a safety hazard, as with regular checkups, the tires were so low that one is at 0/32nd. Upon showing giving me the printout after measuring, the dealership told me I could drive on the tires a few more months. This is a major safety concern.
Sunroof exploded (like the sound of a bomb), without warning, on 7/21/22, while driving the vehicle. The shards traveled upward, and broken tempered glass protrudes towards the sky.

Sunroof exploded (like the sound of a bomb), without warning, on 7/21/22, while driving the vehicle. The shards traveled upward, and broken tempered glass protrudes towards the sky. Size of hole (largest points) approx. 16" X 9". It was not a rock or any other debris that caused this--it was internal force. I reached out to the dealer on 7/21/22, and today with pictures, who will reach out to Toyota. No damage was done to the vehicle, to the best my knowledge, other than the sunroof.
While driving around 60 MPH all the sudden I heard a loud explosion like a shot gun going off and then my sunroof exploding and shattering all over me and the interior of my car. There was no impact from another vehicle, rock, tree, anything. It just exploded into thousands of little pieces out of nowhere. It was terrifying. I w…

Several times while applying the brake, particularly when braking slowly and often either downhill or turning a corner, there seems to be a gap in the braking. It feels like I have let my foot of the brake, but I have not. It is very brief. I have taken this to the dealer and they indicated they were able to replicate it and tri…

Several times while applying the brake, particularly when braking slowly and often either downhill or turning a corner, there seems to be a gap in the braking. It feels like I have let my foot of the brake, but I have not. It is very brief. I have taken this to the dealer and they indicated they were able to replicate it and tried to fix it, but the problem has continued. For the approximate date asked about below, it has probably happened at least 50 times and it's happened with our two household drivers.

In April 2022, the sunroof on our 2020 Highlander Hybrid spontaneously exploded (without impact) while driving on the freeway. It was like a loud shotgun went off in the cab of our SUV. We were showered with glass and small cut to my wife's hand. Thankfully there was no traffic otherwise it could have easily caused an accident, putting us and others at risk. The local Toyota Dealership (where we purchased the car from in 2020) took photos (half the glass broke out, the remaining glass had glass shards pointed upwards like a volcano). The Service representative originally advised us that Toyota would likely pay to replace the sunroof and pay for our rental car (as we had just begun a 2-week trip), but then later refused, stating that the sunroof must have had a chip in it or was impacted (which were absolutely false claims). They stated that I must submit it to my insurance who they billed for $2,410 (sunroof assembly remove & replace, new glass, clean-up detail glass shards, supplies/materials, labor), and $500 of which I would have to pay for a deductible. After many difficult emails and telephone conversations, Toyota Corporate finally agreed to pay my $500 deductible but then later handed me a Goodwill Settlement Agreement to sign, stating the matter is resolved and I would take no further action. I refused to sign it, because I had a $1,900 Car Rental bill (less $450 from my insurance), that Toyota refused to pay. There were no warning messages or symptoms. It is a manufacturing defect that Toyota refuses to acknowledge so that customers and their insurance companies get stuck with all of the bills.
