2020 Toyota Highlander

About once or twice a week as I'm slowly braking to make a turn or stop, the car will surge forward. I have to depress the brake harder, and it does stop or keep slowing. I'm very concerned that if this happens as I'm stopping at a cross walk, someone could be hurt. I took it to the dealer who couldn't replicate it, so said it wasn't a safety issue. There are lots of forums that describe this with highlanders. My partner can feel it happen too. I'm not sure if it's the braking system or engine. My guess is engine because it seems to be a power surge. It's inconsistent, and happens in all kinds of weather, hot/cold, dry/wet. No warning lights, or messages. Happens a lot, but I'm using the example of earlier this week. You're welcome to inspect if you want. It is a hybrid and one of my friends said it might be switching systems, but our other car is also a hybrid and doesn't have anything like this happening.

Driving at highway speeds of 75 mph (posted speed), front bumper fell off of car. Outside temperature was 107 degrees. Bumper was lodged under car and all insulation peeled off of wheels. Had to pull all parts from under car and around wheel openings and was able to continue to destination. No accident occurred as the result of this as I was able to safely pull over to side of road.

The contact's wife owns a 2020 Toyota Highlander. The contact stated while the vehicle was parked, his wife noticed that the front passenger's side carpeting was extremely wet. Upon investigating the failure, both the contact and his wife noticed that the carpeting underneath was extremely soaked. The contact stated that both he and his wife used towels to soak up the water. The vehicle was taken to an independent mechanic where it was diagnosed that the HVAC evaporator drain hose was clogged, which caused water to leak into the front passenger's side of the vehicle. The independent mechanic informed the contact that the failure was related to Toyota Technical Service Bulletin Number: 0080-19 (HVAC Evaporator Drain Hose Clogged Due to Insect Intrusion) and referred the contact to the dealer for the repair. The dealer and the manufacturer were notified of the failure and informed the contact that the repair could not be covered under warranty. The vehicle was not repaired. The failure mileage was approximately 12,300.

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.

The front portion of the panoramic sunroof/moonroof blew out with a loud boom while my husband and I were driving on interstate 75 south in Florida. The flying glass could have injured us had the shade not been closed or if it had been raining and possibly caused an accident. I saw that another person had the same experience with a 2018 Toyota Highlander XLE with a panoramic moonroof listed on Toyota Nation on Oct 3, 2019. It has not yet been inspected. Insurance company was notified. No warnings or symptoms of the exploding moonroof occurred prior to the failure. It just happened today about 1 1/2-2hr ago.About 6pm.

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.

THE VEHICLE WAS IN MOTION ON A STRAIGHT HIGHWAY ON A HOT TEXAS DAY WITH NO OTHER VEHICLES IN THE VICINITY AND NO DEBRIS ON THE ROAD AND THE MOON/SUN ROOF EXPLODED (SOUNDED LIKE A GUN SHOT IN THE CAR). THE CAR WAS BRAND NEW AND ONLY HAD 4,000 MILES ON IT. THE VEHICLE IS CURRENTLY LOCATED AT THE LOCAL TOYOTA DEALER BEING EVALUATED BUT THEY ARE DENYING IT AS A WARRANTY ISSUE. THIS COULD HAVE BEEN LIFE THREATENING SINCE IT WAS A VERY LOUD SOUND AND THANKFULLY WE HAD THE INSIDE COVER CLOSED TO THAT WE WERE PROTECTED FROM THE GLASS.
