Brakes reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Fire reported
My wife and I were Driving when I tried to stop and the brakes failed. Within seconds the vehicle caught fire in the engine compartment. I had to slam the transmission into park cause the doors would not open. When my wife tried to escape out the passenger side the flames came into the cabin towards her. I then opened my door and then had to help my wife escape out the driver's side door. Within minutes the car was engulfed in flames. The fire department arrived and it took a while to extinguish. The vehicle is totaled.

I have replaced my rotors and my brakes soon as I got the car I’ve had the car for a month now I was in a major accident. Someone walked in front of my car. My emergency brake system did not work my rotors and my brakes, have been scrubbing ever since I got the car. And I don’t know how to fix the situation. The brakes are still going out and sound very horrible. I can’t keep replacing them because I don’t think they need to be replaced. Is something wrong with the car.

To Whom It May Concern, I hope this message reaches someone who values the sanctity of human life. Today, while driving home, my husband experienced a terrifying incident: the brakes on our car completely failed. Thanks to my husband’s quick thinking and driving skills, he narrowly avoided a potentially catastrophic accident. We immediately took the car to a local mechanic, who informed us that the issue was due to a BRAKE BOOSTER failure. This was the first time we had ever heard of such a part, and the mechanic explained that it was highly unusual for this component to fail, indicating that it may be defective. Although this car is a 2018, it only has 50K miles on it. My husband is retired, and I work from home, so this is very unusual. Upon further research, I discovered that the Kia Sportage had a recall for this very issue. Additionally, I found numerous complaints dating back to 2005 concerning the sudden loss of brakes in Kia Sorentos, specifically due to defective brake boosters. It is deeply concerning that this issue was not addressed with a recall for Sorentos as well. This defect poses a serious risk to drivers, and I fear it’s only a matter of time before someone loses their life because of it. We contacted Kia’s Customer Service to report the issue and expressed our concern that lives are at stake due to this defect. However, instead of addressing our concerns, we were told the part wasn’t covered under warranty, and two customer service agents even hung up on us when we persisted. This is a grave and dangerous defect that demands immediate attention. Numerous complaints about this issue exist, and it’s clear that the brake booster in Kia Sorentos needs to be recalled before it causes a tragedy. Please take this matter seriously and help ensure that this issue is addressed to prevent any further risks to drivers. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
