“I googled and a recall # SC200TE showed it was uncompleted. I called Holly Kia in Felton, Delaware, and they informed me my title is "branded" and therefore not covered under recalls. Then i google the recall again and now its gone.”

Service brakes

5 reports1 crash
“Based on reading some service forms, it seems it may be the hydraulic booster, causing the issue. In order for them to take a look at the brakes system. I was charged a upfront diagnostics fee of $316. While driving warning light comes on " Check brake system " then the car slows down to 10mph immediately. While pressing on the brakes they squeaking, very badly. I have to turn the car off and back on until the flashing " Check brake system" turns off. This happens every 5 to 10 minutes while driving multiple times a day, everyday. This could have caused an accident on multiple occasions. When the warning light comes on, the car immediately goes down to 10mph making it impossible to pullover in time. The car is currently at the dealership for inspection, they're the only ones that i had inspect the car. However reading the Kia forms online alot of other customers are having this same issue. This issue started happening about two months ago. And has progressively gotten worse.”
