Windows, Mirrors & Wipers complaints by model year
While driving my 2025 Toyota 4Runner in rainy conditions, the vehicle’s stamped hood channels act as a reservoir, trapping and pooling large volumes of standing water. Upon braking or decelerating—even at low, around-town speeds—the pooled water surges forward off the front nose of the hood onto the windshield. The vehicle's forward aerodynamics catch this massive sheet of water and instantly launch it backward across the entire windshield, causing total and sudden loss of forward visibility. This creates an unpredictable, immediate crash hazard that catches the driver completely off guard, as the windshield wipers cannot clear the sudden volume of water fast enough to maintain a safe view of the road. This occurs around town driving (25mph to 45mph) and highway speeds (60mph - 70mph). I understand you can turn the wipers on high, but it catches you off guard when it happens.

With the slanted windshield and location of the rearview mirror creates a blind spot when looking to the upper right. Both my husband and I have trouble seeing.
NHTSA complaint #11721093 — an unverified report by a vehicle owner.
Windshield cracked approximately 2” from the bottom all the way across while using the defroster to clear ice from it. I was still parked at the time. I am unsure how long it will stay water tight or become worse. One concern is the crash avoidance and the automatic high beam sensor are both attached to the windshield and don’t want them to fail. I also don’t want the entire piece of glass to shatter and land in my lap while driving. The dealer refused honoring the repair under warranty. They only use one particular repair shop (which I suspect they own) and even quoted me a price for replacing the ruined glass. In addition to paying for that I would need to pay the dealer to recalibrate the crash avoidance and headlight sensor. I have yet to report the damage to my insurance. As of yet there are no warning lights showing.
NHTSA complaint #11716332 — an unverified report by a vehicle owner.
MYself and my fiancee were driving to our family's home, the rear defrost was on due to foggy windows as we were driving down the road there was a loud noise from the back half of the 4 runner. I had turned and looked back behind me and the rear hatch window was completely shattered. Its still intact in the window frame but about to fall out. This happened out of nowhere no warnings or anything.
NHTSA complaint #11703997 — an unverified report by a vehicle owner.
Two separate occasions while driving this car and using the wipers in rain there was been almost zero visibility to the point where we can almost not see while driving in the rain. I have owned three Toyotas and this is the first time I have ever experienced this issue. It almost as if the wipers don't move fast enough to clear the water off the windshield or the wipers aren't making contact the entire time wiping the glass. I took my car to the dealer and the wipers move the same as the exact make model and year. I feel this is a design flaw and could be responsible for a serious crash due to not being able to use this car well in the rain.

Vehicle was not being used at the time. It was in my driveway when the window blew outward. Inspected by Safe lite, Reported to Liberty Mutual. No warning light, rear defogger was not in use, car was off.
NHTSA complaint #11673719 — an unverified report by a vehicle owner.
Driving along the freeway in winter conditions I used the rear defroster for the back window, this caused the back glass to explode loudly, shattering glass onto belongings, animals and the road behind us. This caused drivers behind us to act evasively and myself as well making a winter driving condition more dangerous, not to mention the spray of glass that reached the back seats of my car with passengers. This has been well documented by other drivers and been acknowledged by Toyota in letters and technician bulletins for replacement of the windows, there are no warning lamps, it just goes from working correctly to exploding.
NHTSA complaint #11632738 — an unverified report by a vehicle owner.
The rear window on my 2006 4Runner suddenly shattered. I had just cleared the car of snow, put my son in the car and left the house. Less than 1/10th of a mile down the road it exploded. Glass could have gone all over the child in the backseat. There have been past issues. Toyota offered an extended warranty on the part until 2018, so they are aware of the problem. Not yet. No warnings.

Rear hatch glass broke during defroster operation. Started to smell a burning smell and then moments later the entire rear hatch glass shattered. Known issue by Toyota. They issued a brief Warranty Enhancement Program (ZG7) in March 2017 thru April 2018 but are refusing to honor current issues.

NHTSA complaint #11531831 — an unverified report by a vehicle owner.
The rear windshield shattered suddenly without any apparent reason. At first I thought something had smashed onto our car because there was a loud smashing sound as it a sheet of ice fell on the roof of the car, but it was not a snowy or icy day and there was no rock or branch by the car. It was rainy and cold and I had the wipers and defroster on so the only thing I could think of as the problem was the temperature of the glass and defroster caused the glass to shatter. I had all three of my children in the car (all under 6 years of age) in the backseat and I was lucky none of the shattered glass projected into the air on to them. The entire windshield was shattered.
NHTSA complaint #11498612 — an unverified report by a vehicle owner.
The contact owns a 2019 Toyota 4Runner. The contact stated that while attempting to lock the doors with the key fob, the front passenger’s side door failed to lock as desired. The contact took the vehicle to the dealer who diagnosed that the actuator failed and needed to be replaced. The vehicle had been repaired. Shortly after the repair, the front passenger’s side window failed to lower and raise. The contact returned the vehicle to the dealer and reattached the window’s wiring harness due to the harness detaching. Shortly after the second repair, the same window failed again and the lock on the driver’s door failed to lock. The contact had not taken the vehicle to the dealer yet. The manufacturer was not made aware of the failure. The approximate failure mileage was 40,000.

I was driving my 4Runner and the rear glass exploded and shattered. This is a known issue with Toyota and documented in T-SB-0189-17 and warranty enhancement ZG7. There were no warning lamps, messages or other symptoms of the problem prior to the glass shattering. Toyota refuses to cover the repair costs and the estimate provided by the dealer is $1,200. Photos were taken in my garage when I got home immediately after the explosion occurred.
NHTSA complaint #11482995 — an unverified report by a vehicle owner.
The rear window shattered spontaneously while the rear defroster was on. There was no impact to the window and no prior chips/scratches. The tint held the shattered window together, but without the tint glass would have gone flying inside and outside the vehicle, putting passengers and cars traveling behind at risk. No warnings or issues were present for the rear window or defroster system prior to incident. The problem has been inspected by Toyota of Orlando. This problem is known to Toyota under their enhanced warranty program ZG7, but they refuse to cover the repair because the date to experience the shattering rear window has passed. There are numerous other cases reported of this issue. Toyota of Orlando confirmed this would fall under their ZG7 program, had the window shattered and brought to a dealer prior to 4/30/2018.
