Cruise Control problems of the 2011 Hyundai Sonata

Since I bought this vehicle, they had replaced the engie due to,the recall, they had to,replace my fual sensors, steering column piece, and another part. But since they replaced my engine, my electrical in my car is,mever accurate. Speed sensoer is wrong, the radio shorts all the time, and my cruise control doesnt work. The problems countniue to get worse especially with the electrical. This car has costed me 1000's of dollars and it just countniues to have problems. I have taken it to Hyundai in redlands CA. They have all documentation on the vehicle.

~tl the contact owns a 2011 Hyundai Sonata. On several occasions, while driving 70 mph with the cruise control engaged, the speed increased to 80 mph. The contact was forced to apply the brake pedal twice before the cruise control disengaged to approximately 5 mph. �the failure mileage was 116,350.

Cruise control fails to disengage by repeatedly and firmly depressing the cancel switch on the steering wheel. Cruise control must be disengaged by manually depressing the brake pedal. Upon harshly hitting the wheel in the general proximity of the switch it will sometimes begin to work again randomly, other times it will not function at all.

The buttons and horn on the steering wheel are not working, nothing happens when you push any of the buttons. Cruise control, odomiter reset, trip button, volume, bluetooth, radio station change, and horn do not work. The horn not working is a huge safety issue, I cannot let anyone know I am near or they are too close to me. While driving and while in parked mode.

Cruise control will not cancel with cancel button. Will happen anytime I'm driving on highway and set the cruise control.

Knocking in the engine,cruise control doesn't go off when brake is pressed,shift lock doesn't work. Have to manually press override button to put in gear. Car stalls sometimes after a turn. Ecs light is constantly on. Loss of power sometimes,had to replace brake light bulb twice in the last 6 months and they were completely black,like burnt. Vehicle was generally in motion when issues occurred.

Cruise control wont engage. Buttons for cruse control intermently work. When and if cruise control does engage buttons cancel,set, +/- speed may or may not operate. Setting cruise control and increasing or decreasing accelerator speed may or may not engage. May have no control if unintended acceleration hapens. No control of speed and settings. Numerous Sonata ownwers are having this problem. Google problem and its well know. What is Hyundai doing to prevent or fix the problem if and when unintended accleration occurs. Or is Hyundai going to wait untill someone mentions class action lawsuit like in the replacement of Sonata engines. . . . .

"takada recall" the push to start won't work sometimes, (stationary )it has me stranded at times. I have had the batteries changed several times and it still won't work, my front suspension is making a very loud noise when I step on my brakes(everytime I'm in motion) I've had new brake pads, rotors and $700 michelin tires put on in Aug 2017 and this noise is getting worst, the wiper blades are top of the line and I cannot drive at night or in the rain because it's very hard to see, lastly I try to use my cruise control on the (highway) and I set it and bounces back down very low.

Car makes a loud clicking noise in the steering column when going over 60 mph and when slowing down. When parked, there is also clicking noises when turning the steering wheel. When in reverse, it makes a clicking noise when turning. Gas gauge doesn't work. It now will run out of gas when there are "60 miles" left until empty. The cruise control button will not work. You have to keep pressing it to come on. Also, the button to see trip miles, trip a, trip b etc, does not work on the 1st try. It takes many pushes to get the screen to change.

Tl-the contact owns a 2011 Hyundai Sonata. The contact stated that while driving at approximately 55 mph, with cruise control activated, the vehicle independently decelerated. The contact depressed the accelerator pedal but the vehicle failed to accelerate. The failure recurred twice. The vehicle was taken to a dealer where the failure was undetermined. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 20,000. Ak.

The controls on my steering wheel will randomly quit working. The cruise control will work fine one time and then the next I can't hit set or the cancel button will be the cruise or it will flip through the other options (trip button). If I hit the steering wheel in this vicinity it will work correctly sometimes. The volume button will either mute, or the + will actual decrease the volume. The button to change the station (presets) will change the mode (am, cd, sirius. . . ) sometimes one direction (up) works and the other does something else random. All of the steering wheel controls seem to have a mind of their own and do not work correctly most days vs some days the buttons work fine. I took it to the dealership prior to the warranty expiring and it worked fine. Next day, issues again. I saw other complaints about this but can't seem to make it happen when I need it to. Frustrating since it is safer to use these controls that the buttons on the dash.

In mid--August 2015, my car began to have odd things happen such as the car alarm randomly going off. I replaced the battery thinking it may be the cause. That did not help. The alarm still randomly went off. I did not think this was a serious problem until my daughter was driving at highway speeds. On Aug 14th she reported to me that her steering became erratic regardless of what she did. After she pulled over, she noticed the fuel gauge went to zero and the low fuel light began blinking despite having recently filled the tank. When she got back on the road, the cruise control suddenly stopped working. Finally, within the next couple of days, the brake lights came on and would not go off. This caused the left tail light assembly to completely melt! then, on Aug 24th, she drove the car to o'brien Hyundai in ft myers, FL. They replaced the steering angle sensor, sending unit, brake switch, brake switch stopper, and tail light assembly. They could not tell her or me what the root cause was for this electrical issue that nearly caused a accident.

Tl the contact owns a 2011 Hyundai Sonata. The contact stated that while driving about 65 mph with the cruise control activated, the brake pedal was depressed and failed ot deactivate the cruise control as well as failed to immediately stop the vehicle. The contact managed to control the vehicle until it stopped. There was no warning lights illuminated. The vehicle was towed to the ed voyles Hyundai dealer (770-952-8881, 2135 cobb pkwy se, smyrna, GA 30080) where the failure could not be duplicated or a cause determined. The manufacturer was made aware of the failure and offered no assistance. The failure mileage was approximately 45,000. Fe.

The contact owns a 2011 Hyundai Sonata. The contact stated while driving 63 mph the cruise control was engaged. Upon approaching another vehicle he applied the brakes in order to disengage the cruise control but the vehicle accelerated and crashed into the rear end of a vehicle. Upon impact, the air bags did not deploy. No one was injured. The police were contacted and a report was filed. The contact was able to drive the vehicle from the crash site. The vehicle was taken to an independent mechanic to be repaired; however, no one investigated the cruise control failure. The failure and current mileage was approximately 26,000. Updated 06/05/12.

This is what I wrote to Hyundai: rented a Sonata from avis. Loved the car except: safety issue. While using the cruise control the car leaped ahead several times after I had applied the brake (because I was getting too close to the car in front of me) and was temporarily handling speed without the cruise control. Nearly had an accident on twq such occasions. Then I figured out what was happening. The "resume" button is so close to the rim of the wheel, and so exposed, that the heel of my right hand was touching it inadvertantly and the cruise control reengaged when I didn't want it to and didn't know it was happening. Imho, your button needs to be relocated or protected by a ridge. Imho, this is a major safety issue that needs to be addressed now. Please let me know if you agree. If not, I will contact the ntsb. Thank you. Hyundai did not agree that it needed immediate attention, so I am writing to you. I noticed on your site that there were two previous complaints regarding the Sonata's speed control, one of them similar in symptom, although the complainant did not recognize the cause. Please note, this was a rental, not a purchase, but to get through your form I have to say, later, that it was a purchase. I also invented the mileage, as I do not recall the mileage on the rental car.

While driving at 55 mph on the highway, the car self engaged and set the cruise control with no driver input. The car started to accelerate to a higher speed, but stopped accelerating when the brake pedal was pressed. The cruise control was off at the time of the incident. The car is less than 2 months old and has already been in the shop for other cruise control related problems. This car is the new Sonata hybrid and has had multiple other problems requiring numerous visits to the service department.
