Brakes Failed problems of the 2014 Hyundai Elantra

My wife was in stop and go traffic on the highway and the brakes failed to work, and she rear-ended the vehicle in front of her. We went to the Hyundai dealership nearby and they tested it for two days and could not replicate the issue. On one of their tests the engine died and the brake system failed but they had not yet hooked up the diagnostic equipment so they never captured the source of that failure. All other times the breaks and the engine worked fine. The result was that they cannot diagnose the problem.

I was driving in stop and go traffic approximately 30 - 35 miles per hour and I had to slam on the brakes of my 2014 Hyundai Elantra to avoid collision with a car that was stopped in traffic for no apparent reason approximately 8-9 car lengths in front of me and the brakes failed. The brake failure caused me have an accident as I had no other choice and no other way to stop the car except to rear end the car in front of me. That's the only way the car stopped. Instead of stopping when I put my foot on the brakes, I had no brakes at all and the car skidded over the length of 8-9 cars and only stopped when I hit the rear end of the car in front of me. When I initially put my foot on the brakes I felt a "thump" through the brake paddle and then I had no brakes. There had been rain earlier in the day, but at the time of the accident it was not raining. There was slight rear bumper to the car that I rear ended, but with the impact of the accident my car is basically totalled - front bumper and side lights were damaged and fell off of the car, my engine was pushed down, one of the motor mount bolts was totally broken off, the hood and the radiator were smashed in, valves were damaged, manifold was cracked, ac and heater damaged and I do not have any brakes as can be verified by my mechanic. For the speed that I was going in stop and go traffic I don't see how I could have had this much damage. It's unbelievable. All in all I am lucky to be alive and uninjured. I'm afraid to drive this car ever again due to brake failure.

The contact owns a 2014 Hyundai Elantra. While driving approximately 35 mph, the brakes failed without warning. The contact stated that the failure occurred at least twenty times during the past year. The vehicle was taken to the dealer once for diagnostic testing, but was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 50,000.

Returned home from work and parked vehicle in driveway, got out and got groceries from passenger side. Went inside and about twenty minutes later was informed by neighbor that my car had rolled out of the driveway, across a 55 mph street, and through ditch into neighbors yard. When myself and three other people approached the vehicle we were astonished to see that the e-brake had been engaged and yet the vehicle rolled down driveway with no signs of tire dragging. It is as if the e-brake completely failed for a short period of time. There are other Hyundai's of similar build recalled for "parking break issues causing dragging while driving and possible rollaway while parked". Sadly Hyundai is not helpful because my exact car does not have a current recall going. I believe that my car has an issue that is a defect of the caliber that creates the amount of damages necessary to recall a model of vehicle. Death or serious injury could have resulted due to the malfunction of the parking brake in my car. My vehicle has incurred above $3,000 worth of structural and body damage from rolling away at no fault of my own. It is currently at a repair shop and I am pursuing a claim with Hyundai but they are not doing what is best for the safety of consumers. An inspector should be out to look at my brakes regardless of the outcome, circumstance, or fault. Instead of trying to avoid paying for my car they should be looking into if this malfunction could cause harm and property damage to other people. Thank you for caring about the safety of our cars and roads.
