Electrical system, Structure, Engine, Dec 6, 2021
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.
