2023 Kia K5 GT, 8300 miles. Took car for 1st oil change and dealer said front brake pads and rotors need replaced. $800. The car is driven to school and home. How is this possible? Brakes should not be worn out this fast! Does this mean every oil change appointment will be $800 to replace brakes again. Reading forums this is a common issue for this vehicle.
This is the letter I sent to Kia: Dear Sirs, I own a 2023 Kia K5 EX that I bought new and currently has about 8500 miles on it. Today, while driving on I95 in Florida, I had my right rear tire blow out. I could tell by the feel of the car that I had a flat before the systems warned me, but that is not why I’m writing you today. While I was working my way over to the right shoulder to stop, all of the waring lights came on and the brakes stopped working. Now I want to be clear. It wasn’t a failure of the brakes themselves. It was not the anti-lock brake system. The brake pedal itself locked and would not let me apply the brakes. Again, I want to be perfectly clear here. I am now driving on a 6 lane highway at about 50 miles and hour on three tires with no working safety systems and I cannot slow down the car. Eventually, the brakes came bake on line and I was able to stop the car. However, If the traffic suddenly slowed down, as is common on South Florida, I would have had no way to avoid a collision. I do not know if this is a programmed response to a tire blow out or a major flaw in your safety systems. If it was designed that way, fire the moron who designed it and have it fixed. If it’s a flaw in the design, have it fixed. I cannot believe how dangerous a car you let me drive.
