Filed Jan 15, 2017 · Acceleration, Brakes · 60,000 miles · CA

After receiving letter from hyundai about defects in cruise control and other technical items, I took my car into dealer in fresno, california and they turned me away refusing to service recall order to fix and replace recall requirements stating that they did not have time and that they would call when they did. They never called, my contact number has never changed in 15years or more.

We were driving on the highway when the car began to accelerate on its own as if cruise control was on, which it wasn't. We pulled over and pulled the floor mats off in case they were making the gas pedal stick. When we started back up, the car did it again. We tried to pull over again and the brakes didn't stop the acceleration until we threw the emergency brake on. Even then, the brakes were fighting the increased acceleration. We then made our way off the expressway and were able to brake the car enough to turn the engine off. We called a tow truck to bring it to the shop. We are grateful we didn't get in a car accident and are still pretty freaked out about it.

In march of this yr, a friend informed me that my driver side brake light was out. I had the bulb replaced & then got a notice about the recall. The work was performed in june (replacement of a stop switch I believe is what it was called)..........last week I went back to the dealer for a couple of problems that I felt were recall related. Both my driver side brake light was out again, my third brake light was out & I informed them that one day I was having a problem moving the gear shift out of park. All of these I felt were recall related but was told that they are not.........that the elantra has a history of burning brake lights out. And I was told that if the problem w/the gear shift happens again, to bring my car in. I feel that this recall, between the fact that the brake lights keep burning out, cruise control can be difficult to disengage & having a problem w/the gear shift are all pretty serious issues. I feel like there is still a safety issue w/the elantra. I don't think the work they did fixed anything.

The cruise control on hyundai elantra failed to disengage while I driving on highway at 70 MPH despite repeatedly pushing the "cancel" and "off" buttons. Firm braking also failed to disengage the cruise control. I managed to stop only after pulling the emergency brake and applying heavy/maximum braking. Smoke. Tires destroyed. Scary! My child and I almost died. The ABS and ESC off lights came on and remained on. Kia and hyundai recently recalled 1.9 million vehicles to fix this issue. However, this incident suggests that hyundai has not fixed the problem because my car had the recall procedure completed one month prior to the incident occuring.

I purchased a new 2008 hyundai elantra in april, 2008. In june of 2008, car surged while at red light. Dealer could not replicate problem, no repair made. Surging happened again in june of 2008, dealer replaced cruise control cable. In april of 2009, surge happened again, dealer replaced fuel sensor. This was a very dangerous situation, so when it first happened, I opened a case file with hyundai. Each subsequent time, I reported it to hyundai, as well. The last time it happened was in october of 20l0. At this point, I traded the car in at the hyundai dealer where I purchased it. I told them that the car was unsafe and should not be put on their used car lot for sale. Today, I discovered that the car is for sale on their lot. I spoke with the owner of the dealership who said that he would request time from hyundai to "tear the car down" in an attempt to locate and repair the problem. This car is extremely dangerous. The surging happens when the car is idling at a stop, so a pedestrian crossing in front of the car is in danger, or a rear-end collision could easily happen at a stoplight. I reported this to hyundai consumer affairs today.
