Notes: There's an emerging trend of transmission problem with the 2010 Elantra at fairly early mileage.

So far owners report having the transmission replaced under warranty but that won't hold up for much longer. It may be a bit premature but for now we're putting the "CLUNKER" rating on the 2010 Elantra just to be safe.

Speaking of being safe, you might not be unless Hyundai can figure out why their airbags aren't deploying.

problem #9

  • 60,000 miles


While my wife, linda, was driving less than 1-2 mph, turning into a parking space, all of a sudden, the engine started racing and leaped forward. Hitting the brakes had no effect on stopping the vehicle. She desperately turned the wheel to miss parked cars, a steel pole was hit and torn out of the ground by the runaway vehicle. Finally the car came to rest after hitting a large concrete light pole, which must have stalled out the engine. My wife was in a state of shock and had to go to the hospital for tests / xrays. Even with the seat belt on, she received major impact from the steering wheel to her chest.

The contact owned a 2010 Hyundai Elantra. While driving 13 mph, the vehicle accelerated. The brake pedal was depressed and stuck to the floorboard and the steering wheel locked. The vehicle crossed opposite lanes and crashed through a gate and into a house. The air bags deployed long after the crash occurred. The contact was knocked unconscious momentarily and received medical attention. A police report was filed. The vehicle was destroyed and towed to a tow yard. Three months later, the contact received notification of NHTSA campaign numbers: 13V113000 (exterior lighting, service brakes, hydraulic) and 15V1000 (steering). The manufacturer was made aware of the failure and requested information to investigate the failure. The VIN was invalid. The failure mileage was approximately 63,000.

My wife owns a 2010 Hyundai Elantra and the complaint I've got is about the lug nuts. I had to replace the rear brake pads, brake shoes and rotors. The first problem I ran into on this project was that the lug nuts were so rusted that the lug wrench supplied with the car wouldn't fit over them - the chrome plating on the nuts had deteriorated allowing rust to built up underneath the plating so that the wrench wouldn't fit. (I thought of those individuals who had to change flat tires on the road and wouldn't be able to get the flat tires off.) I called the dealer to see if new lug nuts were covered under warranty but they said no, that they'd give me a 'deal' of $10/nut - around $200 to replace all them on the car! I still have the rusted lug nuts on the car but carry an additional wrench that will fit over them. I did manage to replace all the parts, including rusted and warped rotors mentioned in some of the other complaints I've seen but caution anyone who plans to tackle this job to be prepared for a grueling job.

The brake booster vacuum check valve suddenly failed while driving resulting in vastly reduced braking power and near inability to stop the vehicle. I was lucky to have been able to let the car slow naturally and turn onto a side road. If I had been approaching an intersection I could have easily been injured or killed. When inspected the vacuum line was completely disconnected from the valve resulting in no power from the brake booster. This part of the vehicle had never been serviced.

At 36,000 miles I needed all new brakes and rotors and the 2 front tires were completely worn to extreme unsafe condition. Spent over $680 to repair it all.

The car revving when the cruise control is on and pushing on the breaks then not being able to put the car in reverse or park. I had to use the shift lock release to just be able to get it into park after that.

I took my vehicle to Firestone auto for an oil change and inspection. The technician found that when he applied the brakes they pulsated. Upon further investigation he found that all of the brake rotors are rusted and pitted. The rear rotors are worst than the front. He also noted that the rear brake shoes are worn out and need replaced. Normally the front pads are replaced twice to once in the rear. My guess is that the rotors caused the rear pads to wear out prematurely. I contacted Hyundai and they said that the rotors are warranted for 5 years / 60,000 miles but only manufactured defects are covered. They said that rusting and pitting from weather conditions is not covered. Should I have kept them oiled so they didn't rust? I have a 2006 Kia with over 113,000 miles on it and the rotors are still perfect with no rust or corrosion. Both vehicles have been exposed to the same driving and weather conditions. Had I not paint for the vehicle inspection and been told that the rotors and brake pads were bad. I could have been subjected to brake failure or possibly one of them hanging up and causing a spin out condition.
