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.

While driving straight on interstate at 65mph when the traction control light came on for over 30 seconds and drastically slowed the vehicle to under 20mph. Weather conditions were completely dry and road surface was smooth. Hazard lights were put on to warn other drivers from possible collision and I pulled over. This has happened on two occasions in a 3 week period. Car was taken to dealership where they said no codes came up and they could not replicate described problem. A recall was issued in 2011-2012 for similar issue on same make and model.

The ESC (traction control) randomly comes on while cruising at highway speeds on straight, level, dry roads (often on interstates). Sometimes the ABS lights also light up. Brakes are applied and power to the engine is suspended making the can nearly impossible to control properly. My car has been in the shop now under warranty for over 60 consecutive days and the dealership and Hyundai cannot determine the reason for this malfunction. After repeated requests to have the car repaired under warranty, this car has been in an accident and I have asked Hyundai to determine the relevance of this repeated malfunction in the accident where the car would not stop quickly enough to avoid another motorist. This car was purchased used with 20,185 miles on it and currently has around 22K miles and is under a bumper to bumper warranty.

08-26-16 while pulling into a parking space at a public park while doing less than 5 miles per hour, I experienced rapid unintended acceleration, plowed through a fence, sideswiped a tree, went off a grassy median back up onto a grassy median and then bounced off of that before the car finally came to rest. My brakes did not work and I had no control over the vehicle. It is a miracle that I am not dead as the park is on a very busy 4 lane road and is usually full of children.

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.

I has recently traded in my 2012 Hyundai Elantra for a 2014 Hyundai Elantra. The 2014 had started doing what the 2012 did occasionally, accelerate when I released my foot from the gas to switch to the brake to begin slowing down for a light. After I've applied the brake and I'm coasting before I need to apply it again, the car will accelerate. I used to think it was my imagination, then I read others confirming it does happen. Lately I've also had an issue with the car accelerating when I do touch the gas, the engine revs up and bolts forward like I floored it, but I only lightly touched the gas. I'll be bringing it to the dealer soon for these issues.

I was driving my 2014 Hyundai Elantra (that I had only had for 3 months, had 1,500 miles on the car) home from the airport, had my cruise control set on 55 for the previous 30 minutes, and I noticed the car in front of me was braking. Naturally, I pressed the brake as well to slow down, but the brakes did not work. The brake pedal was hard as rock and would not press in at all and therefore I could not slow down and cruise control did not disengage. I kept trying to press the brake as hard as I could, but the brake pedal was hard and would not work and cruise control kept accelerating. I pressed the cancel cruise control button on my steering wheel, but that did not disengage either. Just has I was shifting my car to neutral, my car rear-ended the Lexus in front of me. After my car struck the Lexus (my foot still on the brake pedal), I felt the brake finally press in and I was able to slow down and pull off the side of the road. The brake malfunction is still under investigation, but upon my own investigation, I found a recall of Hyundai Elantra year models 2007-2011 for this very issue that caused my car accident.
