While driving on the freeway in the evening about 10 minutes into the drive, a loud bang was heard like a shotgun and the front portion of the panoramic sunroof had shattered. Small shards of glass entered the cabin but fortunately no one was injured inside the vehicle. No sign of a rock hitting the vehicle or defect in the panoramic had occurred prior to this incidence. It appears to have occurred spontaneously. There was a large hole in the glass with an outward projection like the pressure inside the vehicle somehow blew out the sunroof. The passengers in the vehicle were at risk of being covered in small shards of glass including a small child in a rear facing carseat who was sitting behind the driver's side. The driver and front passenger would have been impacted as well if the glass gave away. This occurred at high speeds on a freeway where if the glass would have fallen inside the cabin could have caused the driver to be covered in glass, injured while driving at high speeds and caused a wreck. The incident was reported to the highway patrol who could not place a formal report because they said it was not a mechanic defect and the Toyota corporate office said that they could not report because it was a glass issue. Insurance has not been informed yet as we are waiting from the local dealership to see if they can assist. There were no warning messenger prior to this problem and it occurred spontaneously.
There is an open recall which has not been addressed in a timely manner. The below has been open since OCT 26, 2023. I have been advised that I would be notified when a remedy was available but it's been ten months with no solution. My front bumper detached while I was on the interstate causing damage to the front end of my vehicle. The subject vehicles are equipped with a resin front lower bumper cover assembly, connected with mounting tabs. If there is minor impact to the lower front bumper cover assembly that causes the mounting tabs to detach from the vehicle during normal operation, one or more parts of this assembly could detach, which could become a road hazard, increasing the risk of a crash or injury for other road users.
This is in reference to a 2020 Toyota Highlander. The Air Conditioner is not functional. Upon inspection by a mechanic, and $300 of freon wasted, it was determined that the lines that carry the AC to the rear of the vehicle are defective. Freon immediately drains. We have a case open with Toyota. The Toytota Case Manager acknowledged that the lines are a known issue, however at this time there is no replacement part available to fix the issue. The initial exchange with Toyota in early June resulted in a response that the part ETA was expected for early July. They have delayed twice since, to Late July, and now the status is pending with an ETA of late August but "subject to change." The vehicle is not drivable with the heat of Summer months; at times the internal temperature of the car is well over 100 degrees. I would anticipate people that live in southern year round hot climates with this issue can't drive it at all. My primary concern is having no AC is a safety issue for passengers, including children and an elderly family member [XXX]) for which I am a caretaker, and pets. Toyota did not respond to a request to provide a rental vehicle until the part is available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Rear AC lines are defective and are failing on vehicles releasing gas under the vehicle. Dealer has confirmed this is a known design issue caused by dissimilar metals between the vehicle, bracket and rear AC lines. Toyota has stopped supply of the defective part but has no solution to repair this issue yet. They have no solution other that to wait for a) Parts to be re-continued, b) wait for Toyota to release a design fix. Meanwhile I have a newborn and the car is unable to maintain a acceptable temperature for occupation

I was pulling into a parking space in a parking garage. As i was pulling in, the car unintentionally had a rapid acceleration event and crashed into a cement pillar causing the car to be a total loss
The vehicle continues to place excessive wear on the right rear tire despite the auto dealership service department stating there is nothing wrong with the vehicle. My tires have been replaced 4 times with 89,000 miles on the vehicle. The dealership service department is not willing to look into it any further and states everything is normal despite something clearly wearing this particular tire every 20-25,000 miles.
Nav Search and Voice message dictate disabled. Highlander 4th Generation (2020+) Has anyone experienced a DCM failure? My 2020 Highlander LTD hit 70K and 3yr mark; all of a sudden my Nav won't search while driving and I cannot dictate a response to a msg. Other forums suggest, reset the DCM by disconnecting the battery for a minimum of 30 minutes. This can be problematic. NO hands free driving capability.
Random loss of braking feeling and jolting forward when stopping due to regenerative braking letting off. Happened randomly since purchase. Happens around 20mph mark
On March 20th while on the freeway my 2020 Toyota Highlander sunroof exploded. Related or not, I had just rolled up my driver's window immediately preceding the explosion. The sound from this was loud and surprising. Thankfully I was able to get to the right lane and exit the freeway. Upon stopping and viewing the sunroof I was surprised to see the remaining glass pushed UP out of the car. I had no warning nor was I in a situation that I would have expected there to be a problem. I have an appointment 3 days after the explosion at the dealer for them to check it out.
The driver side mirror shakes and vibrates while driving. This is distracting and makes it difficult to concentrate on surroundings. This happens at all speeds. My dealership said that it is normal, but I see many other people on forums have similar complaints. The passenger side mirror does not rattle.
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!
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. 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 was able to safely pull over. There were cuts experienced.
On several occasions, using the key fob to remote start the car, once unlocking the car, the car doesn't turn off as it should when unlocked or touching the drivers side door. Once in vehicle (car still running), car is unresponsive until shifted from Park, then the engine shuts off and car is disabled for 10-15 minutes. Will not start, unresponsive to touching the push start ignition and dash says "Not ready to Drive." Brake pedal gets very hard. Have been unable to video the actions of the remote start in order to get it to a dealership.
I was driving on the highway at about 65 mph, there were no cars beside me, when there was a loud explosion type noise. I noticed the passenger side mirror had flipped into the window. The cover on the mirror exploded causing damage to the hood and side panel of the vehicle.
I was driving on a freeway with no cars in front of me and no debris in the air when our panoramic sunroof spontaneously exploded. The glass blew upwards and the remaining glass around the edges were pointed upwards as if the window had suffered an internal to external impact. Fortunately, the fabric was closed and it could have resulted in a severe accident with glass going everywhere.
Several times pulling out from stop signs I failed to see cars coming from the passenger side. On August 4th 2021 I failed to see a car until it was directly in front of me and I collided with it. Wondering how I could have failed to see it I started doing research on the internet. I discovered others had this same problem also involving an accident. It was brought to my attention the mirrors are large and placed high in regards to the passenger window. I noted others sighted their height as part of the problem. I have a bad back and kept my seat low to ease getting in and out of the vehicle. My vehicle was totaled but the air bags never deployed and no one was injured.
