2021 Toyota RAV4

I am reporting a serious safety concern involving the sunroof glass on my 2021 Toyota RAV4 Hybrid Limited AWD. On July 3, 2026, at approximately 37,350 miles, I was driving the vehicle when the entire sunroof glass suddenly and catastrophically shattered. There was no traffic around me, there was no debris in the roadway, I was not traveling under an overpass, and I am not aware of any impact or other event that could have caused the glass to break. The failure was completely unexpected. I heard a very, very loud sound, similar to a gunshot. Immediately afterward, the entire sunroof glass had shattered into small granules. A very small piece of shattered glass also flew off the vehicle. I was able to quickly close the interior sunroof visor, which fortunately prevented the majority of the shattered glass from falling into the passenger compartment and prevented injury. There was nevertheless some glass that fell into the roof liner. I immediately contacted my insurance company and the car was towed to my Toyota dealership. The sunroof was replaced with a Toyota original part and the replacement was paid by my insurance company. This incident created a significant safety hazard because the sunroof glass failed suddenly and violently while the vehicle was being driven. The extremely loud explosion-like sound and the sudden loss of the sunroof glass could cause a driver to lose control of the vehicle or could result in glass striking occupants. In this instance, I was fortunate that the visor was closed quickly and that there was no surrounding traffic. I believe NHTSA should investigate whether there is a defect or other safety-related problem with the sunroof glass or its installation in this vehicle, particularly if similar spontaneous breakage incidents have occurred in other Toyota RAV4 vehicles. I am reporting this incident because the glass appeared to fail spontaneously, without an apparent collision, road debris, overpass, or other external impact.

My 2021 Toyota RAV4 began experiencing intermittent shuddering and vibration at low speeds around May 2026. The condition occurred while accelerating from a stop or at slow speeds and became more frequent over time. Because the problem was intermittent, the dealership was initially unable to duplicate it. Independent inspection later found dark transmission fluid containing metal debris, indicating internal transmission failure. I was informed the transmission requires replacement or rebuild. My vehicle has approximately 94,000 miles, which is well below the expected service life of a modern transmission. The symptoms are consistent with numerous reported complaints involving Toyota’s UA80 automatic transmission and torque converter. An unexpected loss of smooth power delivery or hesitation during acceleration creates a potential safety risk, particularly when entering traffic or crossing intersections. I am submitting this complaint so NHTSA can investigate as this is a very dangerous and concearning issue.

What component or system failed, and is it available for inspection? The roof/water sealing system failed, allowing water to enter the vehicle interior. It is available for inspection upon request. How was safety put at risk? Water intrusion through the roof caused visible mold growth, interior deterioration, and a severe foul odor. The mold and contamination inside the vehicle is causing constant illness to the occupant, creating a serious ongoing health and safety hazard. Has the problem been reproduced or confirmed by a dealer or service center? The vehicle was brought to a service center for inspection, however they refused to inspect it. The problem has not been formally confirmed. Has the vehicle been inspected by the manufacturer, police, insurance, or others? The vehicle was taken in for inspection but the dealer/service center declined to inspect it. No manufacturer, police, or insurance inspection has taken place. Were there warning lamps, messages, or symptoms prior to failure? When did they first appear? No warning lamps or messages appeared. The symptoms that developed include: Water entering through the roof Visible mold growth Interior deterioration Severe foul odor described as "rotten rat" smell Occupant experiencing constant illness due to exposure

Upon taking my 2021 Rav4 Hybrid in for the rear traction motor cable corrosion recall (25TD01) on 5/7/2026, I was told there are no parts, no estimated arrival time, and therefore not even a rough estimate for a timeframe of repair. I was told that no one would inspect or evaluate the part in question to indicate if the car was safe to drive. I expressed my extreme concern given the recall includes risk of power failure, even while driving. I received inconsistent, avoidant answers and an absolute denial to remedy the situation in any way. I was told the dealership is "Dolan" and not "Toyota". I again expressed my concerns about safety and the dealerships' denial to, at minimum inspect the recalled part and/or housing of the part. Emily, the Service manager stated that Toyota does not "allow" loaner vehicles for this particular recall. She could not provide any sources for this information. To summarize; the dealer with not provide an inspection of the recalled part and/or housing, or give an estimated timeline for repair given I am #125 on a waitlist. There is a complete lack of regard for mine or my children's safety as the dealer will not provide any assessment of how bad the damage could be. They suggested that I continue to drive the vehicle, acknowledging all of the safety hazards that could occur. I am terrified of the possibility of having an accident with my kids in the car due to this recalled part failing, not having a vehicle to get to and from work, and the potential additional costs that this unaddressed recall issue could cause. Please advise!

On 2/24/2026, while driving down I-5 Freeway, the panoramic sun roof spontaneously shattered while I was driving. It sounded like a gunshot. Nobody was injured. There was no accident. I pulled off the freeway and the WASDOT incident response truck pulled off with me to inspect. He taped the shattered and cracking glass until I could get to Safelite in Federal Way and get a crash wrap so glass didn't continue to fly off while I was driving. I contacted my glass repair team and he reported to me that this has happened with thousands of my toyota cars. I will be calling the dealership today.

I was driving for less than 5 minutes when my sunroof exploded and shattered out of nowhere. My safety was put at risk for several reasons - 1) it sounded like a gun shot had come at me while I was operating the vehicle which was extremely startling. 2) Glass could have shattered all over me and affected my sight on the road. 3) I had to pull over on a busy road not knowing where glass was in my car. 4) This happened due to NO impact, out of NOWHERE.
