Two problems related to brake fluid leak have been reported for the 2007 Hyundai Sonata. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Hyundai Sonata based on all problems reported for the 2007 Sonata.
All 4 brake lines were corroded and leaking break fluid, which prevented the car from stopping when depressing the brake pedal. Mechanic thinks the plastic cover around the break lines may be trapping water and causing corrosion. This is hazardous and unsafe.
My daughter was driving on a city street, and lost all brakes, she pulled into a parking lot and parked. I crawled under the vehicle to find brake fluid dripping under the rear passenger area. After further investigation, after removing factory plastic brake line shield, I found both brake lines totally corroded so bad that one was leaking. I then had to replace the brake lines & bleed. I do believe the plastic shield holding the road grime & moisture to be the culprit. Very dangerous situation!!!!.
