2019 Toyota Highlander

November 7, 2023: While driving across the California desert at 70 miles an hour, temperature was 71°, and freeway traffic was light, without any other outside influences, the sun roof spontaneously exploded, blowing outward, as though someone had put an explosive between the glass and interior of the vehicle. it sounded like a shotgun blast. I pulled over and examined the vehicle; the remaining glass in the sunroof was blown out, arched above the roof of the vehicle, with a spray of shattered glass inside and on the roof of the car. There were no vehicles around me, no impact, and I’m returning home, I reviewed my dash cam looking for other signs (like a bird crashing into the roof). There was nothing. Upon searching this mystery, I found that many others have experienced the same thing. The car is now at the dealership. The car is well cared for, and the roof/glass, prior to the explosion, was undamaged.

The front bumper keeps popping out. I’ve returned it to the dealer 3 times, who says a clip has to be replaced. However, it’s not covered under the extended warranty and they will just replace it. The dealer told me to just push it back in when it pops out. It will push back in place, but it will not stay in place. It has not been damaged.

The car turns off when driving which was supposed to be corrected by recall. It doesn’t appear the recall has been successful in correcting the issue. I actually am not 100% sure they actually swapped out the recall part so I’d like that checked. I also purchased a new battery from the dealer about 3 weeks ago and the problem actually got worse in that it stalls while driving or resets the computer while driving at least once a week.

Originally, 2019 Toyota Highlander lost engine power, steering, and braking on U.S. Route 30, a very busy highway. Managed to pull off side of road AND WAITED. AFTER A FEW MOMENTS CAR STARTED AND RAN AS EXPECTED.Took to local dealer who had the car for several days, but couldn't identify the problem. This instance was 2020/2021. Fast forward to this past September 26th. Pulling out of a private parking lot the car stalled exactly as it had previously.This complete failure of engine is going to get me killed. Further I now notice my dash lights are dimming for no reason then coming back to bright. Now I read where other Highlander are doing the exact thing. I have a car, I'm afraid to drive.

Both the right and left constant velocity axels are making noise. The dealer tells us it is under warranty and will be repaired. However, there are no repair parts available and on national back order. The dealer parts department indicates that there have been problems with the 2019 Highlander cv axels, and all replacement parts have been used. My question is how many highlanders have bad cv axels? Is there more of a problem than just a back order. The dealer indicated we could continue to drive the car until it starts to vibrate.

Noise complaint - High pitched feedback screech coming through speaker (potential for hearing damage) that occurs for approximately 5 seconds intermittently upon starting the vehicle. It can happen multiple times in one day or not until a week or two later. We have twice filed a case with Toyota Corporation. The dealer has heard the noise numerous times and upon performing diagnostics has indicated a malfunction with the SOS system- the trial subscription that came with the car expired in January 2023 and the issue began the following month. An on-line search indicates that other owners of the same vehicle are also experiencing this issue.

Experience "dead zones" in accelerator pedal movement. Experience "no acceleration" with first 1-2 inches of travel from idle position. This is constant and does not vary noticibly with speed. I was driving in an suburban shopping area in York PA with three lanes of travel in each direction. I intended to move from the laft hand lane to the center lane. I indicated my intentions and waited for an opening. I was travelling about 35-40mph. When an opening came along, I steered into the indended lane, but depressing the accelerator to increase my speed, no acceleration occurred. I then panicked and depressed the pedal quicker, and the ensuing acceleration nearly catapaulted me into the semi truck in the center lane ahead of me. I missed the truck by inches. I have had this issue evaluated at Bennett Toyota in Lebanon PA, and the Lancaster Toyota, the dealer who sold me the vehicle in May of 2023, is aware of the issue. Bennett Toyota service department tried to fix the issue by replacing the brake switch. That did not alleviate the problem. I have had several other instances when pulling into traffic when the delayed acceleration caused me issues but no accidents. I believe this issue is related to the selectable "snow" driving function. I think the system is somehow stuck in the "snow" mode at all times. I may have substantiated this today when I experimented with the "snow" function while driving at about 45 mph. When I select the "snow" mode while driving, the accelerator "dead zone" actually gets worse. Bennett Toyota Service response is "it drives like any other Highlander". If that is so - this is truly a huge issue with "drive by wire" tachnology...!!! As a note, at Bennett Toyota I did drive a 2019 Highlander privately owned by the service manager and it did indeed have the dead zone in the acelerator - a fact that the service manager admitted to me verbally. I have read many instances of this issue in chats online.

2019 Toyota Highlander SE V6 FWD - Transmission failing 106000 miles. Transmission has developed a whining sound while accelerating. Fayetteville AR Toyota dealer initial diagnosis was a loose heat shield and recommended a front end alignment, which was done. Noise continued. Independent transmission shop diagnosis was potentially failing bearing, but most likely transmission beginning to fail. Fayetteville AR Toyota dealer, diagnosis upon return, transmission failing, needing replacement. $7,000+ for parts, 5 week lead time to order. Recommended to not drive vehicle as transmission could fail while driving.
