general problems of the 2011 Hyundai Elantra

My car stalls while in motion without warning. While driving the vehicle will randomly speed up and rpm will fly up without command. I also experience a lot of engine power loss randomly the vehicle will bog and be slow. Occasionally when I press on the accelerator I can almost go to the floor with no response from the vehicle. Speed acceleration response is delayed approximately 30 seconds occasionally. Uncommanded acceleration and random stalling when vehicle is in motion has been a big safety risk for me. This issue has been ongoing for awhile. This issue has occurred countless times so it’s very frequent. This complaint is in compliance with the current open investigation regarding the throttle control system vulnerabilities. Nhtsa action number: dp21003.

After getting on the on-ramp on the highway I shifted my manual transmission from 4th to 5th gear to accelerate to 50 mph but the gear didn't shift to 5th and the engine was inadvertently revved up to 4 on the tachometer without any increase in speed; it felt as if I stepped down on the gas pedal while in neutral. I drove the next 25 miles home in 4th gear at 45 to 50 mph.

Tl the contact owns a 2011 Hyundai Elantra. While driving, the electronic stability control (esc) indicator illuminated. The contact stated that the accelerator sensor was causing the vehicle to lose power for approximately three seconds. The contact depressed the accelerator pedal again and the vehicle operated normally. If the contact pushed the esc button, the vehicle would operate normally. The contact called don franklin lexington Hyundai (3340 richmond rd, lexington, ky 40509, (859) 263-5020) and was quoted a repair cost of $900 for the sensor, which did not include labor. The manufacturer was not contacted. The failure mileage was 125,200.

Tl the contact owns a 2011 Hyundai Elantra touring. While driving 20 mph, the vehicle independently accelerated. The contact stated that the failure was intermittent. On several occasions, while the vehicle was stopped at a traffic light, the rpms revved while the brake pedal was being depressed. The vehicle was taken to herb chambers Hyundai of auburn (located at 735 southbridge st, auburn, MA 01501, (508) 832-9990) to be diagnosed. The dealer cleaned the throttle body, but the failure recurred. Additionally, the throttle body was replaced by an independent mechanic, but the failure recurred. The manufacturer was not contacted. The approximate failure mileage was 75,000.

While driving the car one or more of the brakes get active without using the brakes . Abs start kicking and the car loose power . If I hate the brake the brake parks get really sensitive and the car start shaking . Happened too many times and I took the car to the dealer for diagnostic and they said they couldn't fined any problems . From my experience this is a use sensor problem and I spoke with Honda of America and they said my car and my VIN # has no recall .

Initial issue was automatic speed control (cruise cntrl), will not stay engaged. Cruise no longer works in any way other than to turn it on. This issue began around Jan 2017. Next issue is esc off light intermittently comes on and will not reset without restart. Latest issue is the 3rd brake light is the only brake light working. The brake lights and esc issue began around March 2018.

When accelerating, the engine does not always DE-accelerate when the gas pedal is released. This is sporadic and unpredictable. Our mechanic thinks it is a fault in the throttle body. It is dangerous because after accelerating the car will continue to accelerate for up to 10 seconds after my foot is off the gas pedal. Or between shifts (manual transmission) the rpm will go dangerously high because the clutch is pushed in and briefly no load on the engine. The car does not need to be moving for this to happen. It is a throttle control issue, as determined by our mechanic. It has happened numerous times over the last year.

Was parked in a parking lot of a drug store for maybe 10 minutes. Started the car and backed out of parking space. When I put the car in drive to go forward the car accelerated to a very high speed and ran into two parked cars. With help I tried to back out of the space but when I went forward the car once again accelerated to a high speed damaging my car and the two other cars. Several years back I pulled into a parking lot to mail a letter. When I put the car in reverse to back out of the parking lot, the car accelerated at a high speed and backed into a snow bank. I thought at the time that I had accidentally stepped on the accelerator instead of the break but read the exact same experience from a Hyundai owner.

When driving it is difficult at time to regulate my speed. If I stop at a red light and then try to drive on a green light my car will jolt forward. It is hard to speed up, it feels like my car is stuck in on speed. It makes it difficult to drive on the freeway as it is slow to pick up speed.

As I was driving the skid control light came on. At first, nothing was different, then all of a sudden my car started slowing down and would accelerate with gas being applied. Then, it started moving again. After a while the light went off, but then came on and did the same thing.

While driving my vehicle on the freeway traveling at speeds of about 60 mph, my tire pressure light came on, although all 4 tires were previously checked for pressure. When the tire pressure light came on, it triggered the traction control light to begin blinking uncontrollably. The engine then began to clicked loudly as my speed decreased, out of my control, to about 40 mph, although I had my petal to the floor. I then had to exit, taking local roadways as to my speed would not increase past 40 mph with my rpm was at about 4. 5. After notifying the dealership and taking it in to be serviced, I was informed nothing was wrong but reset the computer just in case. Since then it has happened 3 other times with no explanation and diagnostic coming back clear.

I bought this car in 2010 and since then my car started giving trouble they change my transmission 3 time in 100000 mile and after that I started having trouble speed paddle. When I push my speed paddle car will drive without pushing paddle. When stop at light I have to push my brake very hard because my rpm of car is 5000 then I have to put car in nuteral at that time rpm goes more than 5000. Then I went to dealer 1 rickcase Hyundai roswell georgia. They cannot fix same problem again. So I went to other 2 dealer autonation Hyundai mall off georgia. Iwent there for 3 time one time I drop my car for 2 day so they can find problem. My warranty is gone but I am trying to fix my problem. I call Hyundai motors at no 18006335151. Talk to person and he connect to manager and manager is telling we cannot do any thing if the dealer cannot find problem. It is very risky to drive car with this problem if you can help me out I have complain before but there is no response from your side I dont have date and time. Thanks hinaben patel.

The car pulls to the left/right. The steering wheel is sticky. When the wheel is left straight, it will go straight but a small turn to left/right results in very jerky and unsafe ride for higher mileage speed. It is incredibly difficult to drive for longer period of time and on icy roads due to driving behavior. Hyundai says it is because of the electronic power steering. I don't care if it is that. It jerks to left/right while driving which is painful. I have changed tires and brakes thinking those were the culprit. This needs to be fixed before someone gets in a wreck and die.

I was driving my Elantra when the ems elec. Stability control light came on and the auto began to shake as I was driving. The road was dry and weather was regular. It feels as if the auto is driving on flat wheels or on ice. I lose stability in my steering. I have taken my auto to Hyundai twice. They claim they there computers can't find any errors. This is an issue that randomly occur and can't be created at will. I don't feel safe driving while these incidents happen. I've found similar complaints of this issue online with other Elantra 2011 customer. Hyundai doesn't want't to acknowledge that there is an issue with the electronic stability control and steering.

Safety issue driver floor mat keeps getting entangled with gas and brake pedals. The hooks design by Hyundai for there 2011 sonata fails to keep them in place. *updated 12-20-12 smch.

The contact owns a 2011 Hyundai Elantra. The contact stated while driving 30 mph the vehicle suddenly acclerated and crashed into a light pole. The contact was severely injured. A police report was filed. The vehicle was destroyed. The manufacturer was not made aware of the failure. The failure mileage was unknown.

I was turning from gas station onto road, crossing 3 lanes of traffic when vehicle stalled in the middle of the road and I was nearly broad-sided. All dash lights came on, and ac and radio were on, but engine had stalled. After calling Hyundai USA I took vehicle to dealership, reported as stalling at low speed and rough idle. Hyundai USA representative said no problems like this reported. Also service adviser reported never hearing of the problem when took into dealership, despite numerous reports I had printed off the internet. In fact said "we don't acknowledge internet reports as being valid".
