2011 Sonata 2.0T. No braking pressure when cold, slow to stop until car warms up, noise is heard from what sounds like the ABS pump or power brake assist pump. Took to a dealer and was told the noise is a strut tower bar and motorworld group in wilkes-barre refuses to look any father on this issue unless I pay to have the tower bar removed and rechecked. I have 1500 miles on the car and dealer is refusing to correctly diagnose issues unless I pay for it. This is a 2011 Sonata 2.0T SE. The sound is definitely not the tower bar as I can remake the sound on other cars after using brakes very hard. These brakes are very soft and the noise is easy heard and sounds like a pump and a vibration in the pedal.
The contact owns a 2011 Hyundai Sonata. The contact stated that while driving 25 mph, the steering wheel suddenly locked up which caused her to collide into two wooden posts and signs in a grassy area. The brakes would not engage when the contact attempted to stop the vehicle; a hole in the ground stopped the vehicle. The contact also noticed that the seat belt did not tighten to secure her during the incident. There were no injuries. A police report was filed. The contact stated that she previously had the vehicle into the dealer for recall 10V426000 (steering:gear box:shaft sector) on October 8, 2010. The vehicle was at the dealer at the time of the complaint. The manufacturer had not been notified. The current and failure mileages were approximately 4,000.
Brakes failed when trying to stop at red light at exit to parking lot driving between 5-10 miles per hr. Pressed on brake - did not go down. No response - car kept moving until I put gear in park and hit the truck stopped at the light. Driving a 2011 Hyundai Sonata purchased on 5/31/10.
