2012 Hyundai Accent Owner Comments

  • 89,000 miles


On Saturday March 23, 2019 I was driving my 2012 Hyundai Accent on the highway. I was traveling in the left hand lane, on cruise control, going about 73 mph. A semi-truck in the right hand land a few hundred yards in front of me moved over into my lane due to a construction zone ahead, so I attempted to turn off my cruise control to slow down for the merging semi-truck. I applied the brakes but my car did not turn off cruise-control or slow down, but instead accelerated. I attempted again to hit the brakes to turn off cruise control, but again the car did not slow down. I tried both the cancel and the on/off buttons on the steering wheel, but there was no way to disengage cruise control. I was quickly approaching the semi-truck and was unable to slow down my moving vehicle. In order to avoid rear-ending the semi-truck at highway speeds, I was forced to veer left off the highway onto the soft shoulder, and was traveling locked on cruise control at 73 mph halfway on the grass median and halfway on the rumble strip of the soft shoulder. The brakes and steering wheel switches were still not working, regardless of how much I applied the brakes or what combination I hit the switches. I was finally able to get my car to slow down by hitting the clutch and stalling my car. This was an absolutely horrific incident, and I am lucky to have been uninjured and to have avoided what could have been a very serious accident.

Car would not start. Found information online regarding several complaints about a transmission shaft sensor and a quick fix by placing the car in neutral and back to park. Used this fix and car subsequently started.

Around 50000 miles the car would over rev about 1000-2000 RPM when the clutch was released and foot off of the gas. It has progressively gotten worse. Now it will on its own while standing at idle run up to 5000-6000 RPM without warning and the only way to stop it is to turn the car off. When in gear, the car will accelerate without warning. If you depress the clutch, again it will run up to 5000-6000 RPM. The problem becomes exacerbated in warmer weather and lessened in cold weather. During the 12/24 heat wave here in pa, the car was undriveable and dangerous as I could not depend on it not "taking off". the dealer updated the software on 12/22 which did not resolve the issue, and no codes were found in the computer! before 50,000 miles everything was fine.

I was driving down the road during the day and looked down and my high beams were on. I wasn't sure why since my lights were in the off position. I tried playing with the lighting switch on the inside of my car, and it finally turned off after flashing the high beams on and off with the switch a few times. I took a picture, and then started driving, about a mile or so down the road, the high beams came back on, so I headed toward the dealership, and people were moving out of my way on the two lane highway since my high beams were on. The said without being able to duplicate the issue, they couldn't be sure why it happened. When it happened again, I took my car to the dealership with it happening and they played with the switch to get them to shut off and told me I had no clue how to work my lights, that my day time running lights were on, and when I informed him my car didn't have them, he didn't believe me. I kept going back and even had my lawyer get involved since they said nothing was wrong. There were even times when I started my car with the remote start and the high beams came on themselves, and I drove all the way home with no other exterior lights on since I hadn't realized the lights weren't on, since the headlights had been on. Finally went to a shop that they work hand in hand with to install remote starters and remote door unlocks, and they had to call the dealership to tell them that the lighting switch was bad. Before they were called, they told my lawyer I paid bottom dollar for my car and I might as well submit a lemon law request, but they were not going to fix it.
