Consumer Description

Power brake booster check valve has failed twice since purchasing the vehicle new. Shortly after purchase, within the first month, the brake booster would loose vacuum after as little as an hour after driving. It progressed to occasional hard pedal during braking after acceleration. The dealer replaced it under warranty. The same problem arrose last month, April 2021 at 61,000 miles. The dealer said it is no longer covered and they would charge a diagnostic fee and I would have to pay for parts and labor. This is a safety concern that based on internet searches is happening to others. The replacement Part # 591391C200 Brake Vacuum Hose Connector and is currently unavailable from Kia and I had to purchase it from Hyundai.
