On June 7, 2014 Hyundai began to contact the affected retail customers. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 119.

“Power steering failed, car diagnosed with code C2412 & Hyundai refuses to take accountability”

“While driving, I was in the middle of a left turn and had a reduction of the power steering assist system. I had to hit the brakes before entering the opposing traffic. I had to muscle the steering wheel to get out of the middle of the road.”

“While turning in an intersection on a highway, car displayed check hybrid system and shut down. power steering could not engage so braking and turning was almost impossible. Car had to be towed, was not able to be restored”

Filed Aug 7, 2023

“After driving for 15 or more minutes, the power steering fails. The warning light for the power steering and stability control turn on at that moment, as well. This failure occurs while driving and the wheel jerks a bit if the car is in a turn. There was a power steering recall for other Hyundais of the same era, which is very coincidental.”

Should you keep driving it?

This page can't tell you that. 1 of 36 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
