2021 Toyota Highlander

Upon starting my 2021 Highlander Platinum with 10,700 miles on it several warning lights repeatedly came across my display including reduced engine power, brake system malfunction, pre collision system malfunction. See your dealer. No codes showed up on their scan but every time they cleared the screen the messages came back. They decided it was a bad knock sensor. Then I received a call that a critter had chewed wires and they might find further damage. I was surprised because I’ve been in my house for 45 years and I’ve never had a critter in my garage. The service manager said “Toyotas attract critters because of the covering they use on the wires.” I said, “Soy?” And he said, “Yes”. So, isn’t this a manufacturing defect? How many times a year is this going to happen? I’ve owned Toyotas for 27 years. I’ve never had a problem until this car. I’m also having problems with the navigation system, 2 visits to the dealership and 45 minutes on the phone with the Toyota Engagement Center.

I have noticed that if I hit a bump in the road while braking, the brakes release momentarily and I have to press harder to continue braking. I have confirmed that this happens consistently, and is more likely to happen when I am braking slowly (i.e. I'm not pushing very hard on the brake pedal, just slowing the car gradually). This indicates that it's the regenerative brakes that are disengaging when I hit a bump or pothole. It has happened 20+ times and continues to happen consistently under these circumstances.

We have owned our 2021 hybrid awd platinum highlander for 8 months and within the past two months (around 16k miles) it has started to do an acceleration upon applying the brake. The car does catch itself and then after hitting the brake harder it does stop. This has happen on 7 different occasions, flat roads, hills, parking spots now. It has happened while my husband drives it and myself. It was brought it for computer recalls around the same time that this issue started. After the recalls were fixed I brought it back in and left it with the dealer for a few days. They cannot replicate it and therefor won’t do anything. They tried to tell me that I can’t drive with two feet…. Which I don’t. I’ve seen other reports where Toyota claims it’s inexperienced regenerative braking driving. We have owned a 2011 Prius that we had for 6 years and it never did it once. We also had a 2021 Audi e-from which fully relies on regenerative braking. We are not novice when it comes to hybrid driving systems. It has come to the point where I’d like to sell the car and get something else rather than worry about a car crash with my babies in the car. I also owned a 2019 awd regular gas highlander that never had any braking issues. So I don’t know what the solution is, but this is a very expensive car to be having these kinds of issues.

I bought this car in March 2021 to haul my 1st grandchild around. I noticed early on their was something weird happening when I braked, but it occurred randomly, so I thought maybe it's a hybrid thing (or even my imagination). I was the sole driver of the car 99.9% of the time. It gradually got worse over the first 12 months. My husband would occasional drive us to town, but never experienced it, until he did. Scared and concerned for my safety, he didn't want me to drive it anymore. The brakes literally fail when you least expect it causing you to turn too fast, it catapults you forward and you have no control of the vehicle for several seconds. We have had numerous near accidents. I took it to the dealership and they said they fixed the problem with a computer update. I picked it up on a Friday around closing time and got halfway home when I decided I needed Starbucks. Turning into the drive thru I nearly rear-ended a DPS car! GAVE ME A HEART ATTACK! I called the dealership that Monday morning and they said it fixed, but I could bring it back in. Took it back and they basically handed the keys to me and said there's nothing wrong. I told them it's dangerous and when my luck runs out and I have an accident, then what?? Who will be responsible?! No one is allowed to drive my car. My mom, my sister, not even my 21 year old who could drive a NASCAR. It is extremely dangerous and will eventually get someone hurt or dead. I told them I refuse to pick the car up until they figure this out. Gullo Toyota in Conroe, where I bought the car, said my keys are ready when I am. I am contacting a lawyer and filing a complaint here.

Vehicle was driving at highway speed, transitioning to off ramp. Warning lights came on stating Braking Power low. Brakes proceeded to fail. Stepping on brakes did nothing but initiate a stuttering response. Vehicle would not slow down. Rolled into dealership that was luckily .5 miles away. It was diagnosed to be a wheel speed sensor. A sensor failing should not cause a vehicle to be unable to brake. Shocked and traumatized over the incident.

When braking approaching a stop light or braking while having curved into a designated turn lane the car lurches forward even though the brake peddle is properly engaged. This causes one to react by pressing harder on the brake pedal and the brakes thankfully stop the surge . I could describe it as an acceleration during the middle of braking. This could easily cause me to hit the car in front of me, a pedestrian or fail to stop at the stop sign or stop light. This is very dangerous. The dealership has been unable to reproduce the problem. It has occurred 3 times in 10 weeks (as I just purchased the vehicle). There were no warning lamps or messages prior to all three incidents. I input the most recent date that it occurred even though the dealership was unable to see the third incident on their computer readout. They did find the prior 2 incidents IN ADDITION to one in 2020 prior to my owning the vehicle. I have noticed on an internet forum others have experienced the same issue. One case has this number associated with NHTSA 220314000811. PLEASE help!!!

When slowing down, It doesn’t happen all the time, but it’s as if the brakes disengage and the car feels like it is accelerating . After a second or two it will engage after I applied a lot harder because I’m freaking out because it feels like I have complete brake failure. I took the vehicle to Toyota and they told me it is normal to experience this because the breaking system is switching between the electric motors and the break calipers. I have been driving for over 40 years and there is NOTHING normal about this! I have gone into intersections at stop signs and almost rear ended vehicles in front of me as a result of this. Just because Toyota has a problem that they acknowledge, but claim that it isn't a problem, doesn't make it right and it is downright dangerous. This issue has been present since purchasing the vehicle.

The Highlander Hybrid is dangerous and someone will get hurt. The brakes will occasionally, at lower speeds and under a variety of circumstances, stop working for a second or two. It actually gives the feeling that the car is accelerating or surging forward. My dealer was able to replicate the problem but said they hadn't heard of a fix yet. They had heard of this issue from several customers. Toyota maintains it is normal operation and is simply the hybrid switching from regenerative braking to mechanical braking. It is completely unpredictable. Sometimes it will go a week without happening. Sometimes it will happen several times in 1 day. My wife and I do not feel safe in this car. Very frustrating that Toyota doesn't seem to take this seriously. It's simply a matter of time before we rear end someone, or hit something else.
