2020 Toyota Highlander

The driver seat started making a motorized noise 2-3 days after I purchased the vehicle. Over the few months from my oil change the noise got louder and louder as we moved the seat back and forth. When I took my vehicle in for its first oil change I addressed it to the dealership as the seat was now no longer able to move forward or backwards. During their inspection they stated there was a lego which was not possible as I had at the time a 1 & 2 year old who would choke on a lego so there is no way I would allow them to play with legos that small, mega blocks okay because those are huge but legos are too small. Anywho the seat was functionable after the inspection which lasted about a month and then went out again. I then brought it up again at the next oil change which they Checked it out and it worked a bit then went out again. The last time I took my vehicle in for its last oil change I addressed it, they took it apart and left it that way as it is now but were unable to locate the reason why it was defaulted. I however found that a piece was missing from one side of the track under the seat but they couldn't see that it was the reason for the malfunction. I have tried multiple times at least 5 times and speaking with the 2 service managers but to no avail this driver seat still can not be adjusted which means no one can drive my vehicle aside from myself not even in case of an emergency. There are no warning lights or alerts that come up.

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 lane keeping assist does not work properly on my vehicle. The lane keeping assist does not keep my car in the center of the lane as intended. For instance, it very forcefully makes the car drift to the left and right of the lane and frequently pulls it into the other lane. I have reported this to my local dealership - Sparks Toyota in Myrtle Beach, SC and Toyota Corporate. Sparks Toyota service has admitted that there are many customer complaints about this issue. They have stated that there is a software download "fix" in the works, but not yet available. I did not take their word for this and called Toyota Corporate. The only "solution" I have been offered is an offer to show me how to turn the feature off. This is totally unacceptable as the is an important safety feature that does not work properly and in fact, creates an unsafe situation while driving. Since my report of the issue, I have been made aware of an owners Facebook forum that other owners state they are having the same issue and seems to be a widespread problem.

I have a 2020 Highlander hybrid. When I brake my stopping pauses a half second to a second then brakes normally. I am afraid that I can get into an accident due to this happening at the wrong time or if I loan my car to another driver that is not aware of the problem. I took it to the dealer and couldn't reproduce the fault with their computer connected. Though this has been happening about every other day or so. there were no warnings prior, it just happens randomly!

The contact owns a 2020 Toyota Highlander equipped with a Tekonsha Prodigy RF Electronic Brake Control with Bluetooth kits, part number 902501. The contact purchased the unit to use for towing a trailer. The contact purchased the part at an independent mechanic and had the equipment installed by another independent mechanic. When the contact first attempted to use the brake kit, her and her husband had connected the equipment per the instructions and brake kit showed the letter "C" which meant the part was connected. As the contact started driving the vehicle, a NC (not connected) message had appeared on the brake kit. The contact decided to drive the vehicle back to her home and attempted to reconnect the brake system as instructed but the failure persisted. Upon investigation, the contact discovered that the equipment had been placed under NHTSA Campaign Number: 20E033000 (Electrical System). The contact reached out to the independent mechanics, the one who sold the part and the other that installed it, and neither were aware of the recall. The contact also called the manufacturer and had written a letter to obtain the replacement part however, the contact had not heard back from the manufacturer. The vehicle was not repaired. The failure mileage was 0.

My Toyota Highlander is a hybrid and there is an ongoing problem with the brakes under certain conditions. When you are slowing the vehicle down, with your foot on the the brakes, there is a point under 10 miles an hour, where the brakes appear to let go and you must quickly exert dramatically more pressure on the brakes to stop the car. Fortunately it has not resulted in an accident because my wife and I are aware of the potential danger. The danger is, this occurs when you are stopping at a stop sign or crosswalk, pulling into a parking space, or around pedestrians, even pulling into our garage. I have own previous Toyota Hybrids and this vehicle behaves very differently. In my opinion the route of the problem may be the regenerative braking. As you step on the brakes the regenerative braking supplies most of the braking power and then at a slower speed the regenerative braking abruptly dis engages. It seem there should be a way to smooth the erratic behavior of the brakes. I have filed my concerns with the Toyota customer experience center in November of 2020 under my name and file number #2011280027. The car is available anytime to demonstrate the problem, there are no open recalls for this VIN#, and I have been told there are no service bulletins for this problem. The problem has occurred the whole time I have owned the vehicle.

In my 2020 Highlander I approached a stop sign at a "T" intersection behind 4 other cars. After stopping and looking to see road was clear of oncoming traffic, I pulled out and started my left turn. As I was turning into my lane the car engine turned OFF and the steering wheel was LOCKED in the left position. There was no power for the brakes, which left me jamming on the brake pedal as hard as I could only slowing the car slightly. The steering wheel was LOCKED LEFT and I thought I was going to break it trying to force it back. With no ability to move the steering wheel or brake, I braced myself as the Highlander continued turning in the left direction into the other lane. The result was a head on collision with a Mini Cooper, both cars totaled, and injuring both myself and the other driver. Highlander was investigated by forensic company in the employ of the insurance company, but they could not find any error in the cars CDR (Crash Data Retrieval) system.

I WAS AT A STOP SIGN IN MY 2020 HIGHLANDER WAITING TO TURN LEFT ONTO A BUSY ROAD. UPON TURNING LEFT ONTO PA STATE HIGHWAY 999, THE HIGHLANDER ENGINE TURNED OFF AND THE STEERING WHEEL WAS "LOCKED" INTO A LEFT POSITION. THIS CAUSED THE CAR TO CONTINUE TURNING INTO THE OPPOSING LEFT LANE RESULTING IN A HEAD-ON COLLISION WITH AN ON-COMING CAR. WITH THE ENGINE TURNED OFF THERE WAS NO POWER STEERING, NO BRAKES, AND NO WAY TO UNLOCK THE STEERING WHEEL. THE COLLISION CAUSED MY CAR TO BOUNCE BACK AND SLOWLY FREE ROLL BACK TO THE STOP SIGN AS THOUGH I NEVER ENTERED THE ROADWAY.
