We rented this vehicle from Avis at Detroit Metropolitan Airport on Tuesday, 11/22/22 at approx. 7:50 pm. It was raining, cold and temperature was dropping. We drove approx. 1/8 to 1/4 of a mile from the facility. As we turned left on to a major roadway (Goddard) southbound, I turned on the rear defroster. Suddenly, the engine went into limp mode. I tried to make a U-turn to drive back to the facility. Engine lights flashed (low oil pressure, check engine, etc) and then the engine stopped. We barely had enough power to turn the vehicle out of the turn lane before we would have been struck by a bus. We sat in left northbound lane of Goddard for approx. 2 min without our hazard lights on. The vehicle would not start. I then pressed the defroster again and the engine fired up. We drove back to the facility and demanded a new vehicle. While we waited for a new vehicle to be prepared, I demonstrated to the manager what had happened. Again, after depressing the rear defroster button, the engine shut off and would not restart. Again, after turning off the defroster button, the engine started back up. This engine condition was replicated multiple times. I warned the Avis manager not to rent this vehicle as it was a death trap.

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 -€œToyotas attract critters because of the covering they use on the wires.-€ I said, -€œSoy"-€ And he said, -€œYes-€. 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.

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.

Recently purchased this Highlander on August 2021. On 11/29/21 at around 8:00 AM, the Check Engine light illuminated resting stop at a red light. Engine still running. Took the vehicle to the dealership at 9:45AM. Vehicle was found to have had misfires as a result of bad gasoline. I have been pumping at the same gas station ever since I bought the vehicle. If it was the bad gas, this issue should have happened sooner. Now, the dealership is telling me to pay for the diagnostic fee which they claimed it was my fault. The vehicle is under warranty. Another non-power/fuel issue that came with the vehicle was a loud wind noise when reaching 40 MPH. The noise is very annoying, like someone whistling into your ear. The dealership is ordering a part to fix this issue. The vehicle is still at the dealership.

I purchased this 2021 Highlander on April 3rd 2021. Power steering Malfunction, SRS Airbag system Malfuction first happened on April 21th 2021 when I started the vehicle. the car was towed to the dealer ship. the dealer simply re-set the system and asked me to unplug the tracker device which was installed by insurance company. Because they suspected the problem was caused by the interference from the device. I unpluged it. However, Power steering Malfunction, SRS Airbag system Malfuction happened again on May 21th 2021 when I started the car. I went to the dealer who then let Toyota involved this time and changed the battery. However, Power steering Malfunction, SRS Airbag system Malfuction happened for the third time on May 28th 2021.
