The engine has seized. The brake lights were always on and it melted the harness the holds the bulb in the receptacle area. I cannot place the bulb in the seating for it anymore and then successfully place in the area for it. The area just beneath the glove box began emitting smoke and I smelled rubber melting. The language of the car is in spanish cannot be changed back to english. The buttons don't control what they are intended to. The center instrument panel, radio, A/C and the other functions occasionally are not operable, no light nothing.

I no longer have fog lights that entire area has melted. My tail lights go out every two or 3 weeks and the bulbs are black. There is a burning smell coming from the vehicle only when the car is being driven or parked on. The ac line that should be cold is hot. Recently the car was leaking oil and smoking the dealership said it had to do with the engine recall. My engine seized while driving in 2016 and I had to get a engine replacement. After the engine replacement my turbo went out which only allowed the car to drive slow and the engine sounded the whole time driving. It had something to do with when they replaced the engine.

My engine started making a knocking noise, when accelerating, going up hills, or speed limit going up. Makes knocking anytime foot is on the gas pedal. I see there is a recall on my car for this issue. But according to records the issue was only inspected. I have loss of power when going uphill. My car hesitates to start. I have complained numerous times of this knocking issue. But they said they couldnt find it. It started getting really bad 2 days ago, so I stopped at a mechanic who said its definitely the engine knocking. And if it was only inspected at the recall, it needs to be replaced by Hyundai. Because it may cause serious issues. And that Hyundai is responsible for replacing the engine. When it clearly should have been replaced. Even though it may have seemed ok when they " inspected " it. I have 2 children. And expect this to be rectified. As it should have been in the first place. Not just looked at and being lied to. I also see there is a lawsuit against Hyundai for not wanted to replace the engines, knowing they were bad. The noise happens on highways and streets. It doesnt stop. The original recall was #132.

Our car was in the number 2 lane of a 5 lane freeway when it all of a sudden lost power and the gas pedal didn't work and then a very sudden, hard jolt in the car. I wanted to downshift, but the shift lever went to park with no effect. I turned on my turn signal to get to the shoulder on the right. I let the wheels drag along the asphalt curb of the shoulder until I applied the emergency brake and turned off the ignition, by then, the smoke was filling the cabin coming through all of the air vents and my wife and I got out as quickly as we could. It wasn't until then that I found that we had been followed by a tow truck with its emergency lights on and blocked the slow lane of traffic for us and who had his dispatcher call the fire department. The engine in this car had been replaced in March, 2018 under a recall for engine knocking noise. The tow truck driver tried his fire extinguisher, but it had no effect and he stated it would not work because it was a gasoline fire. No injuries were sustained.in order to install the new engine they have to bend the fuel lines out of the way and a fuel line could have been kinked, or was never installed properly. No one had done any work on the engine since it was installed by the Hyundai dealer. I have a fire report, but it is 8 pages. Highway patrol was present, but they do not make a report when only 1 car is involved.

My account |logout show the: Worst vehicles update a car complaint step 2 of 3 -- edit your complaint you wrote... add another one to your list of complaints I was on my way to work and on a major highway when my engine completely seized. I lost power, brakes, and steering. Thank god I was able to coast to the left turning lane or I would have been slammed into from behind and probably would not be here to tell about it. I cannot believe that these cars have not been taken off the road by the nhtsb.when we called Hyundai to tell them what happened their service advisor said "oh yeah that is typical for those engines". so, a car with known engines problems and seizing and known fires is still allowed to be on the road" while at the same time, the car has an ongoing recall for no airbags with no solution to that problem. So if I had been ran off the road with no brajes, power or steering, the airbags probably would not have deployed either. Tge worst part is I took the car to Hyundai 8 months ago and was told that none of the symptoms that my car had, which matched the recall exactly, were part of the engine issue. Seriously" I am thinking, they were wrong. And on top if that. They wanted to charge me to look at it for their recall! after engine seizing, rhey replacef engine... rhree days later, my engine seized. Un -freakin'-believable!

I have had issue after issue with my 2011 Sonata. In just a year and a half I have had 5 things fixed or replaced 2 of them major. I've had the whole break assembly fixed for my break lights not working. Most recently I had to have the engine replaced due to it seizing up with just barely over 100K miles. Then 3 months after that I'm having issues with the cruise randomly turning off, the break lights not working. Also the gear shifter will not go into gear at times. One of the major issues ive had is the engine randomly stalling or the accelerator nor working at all. The issue ive had with the cruise control will randomly happen whether I'm moving or in park and during this is also effects the stability control as well and it will turn its self off. With the car stalling, it randomly happens whether I'm at a traffic light trying to accelerate or while I'm driving.

NHTSA in December 2015 the engine on our 2011 Hyundai Sonata failed while accelerating to merge into traffic on a very busy hwy 101 in the san francisco bay area. We brought our vehicle to the dealership where we had purchased it in May 2011. The following morning we were told by the dealership's service department that the engine had failed and that Hyundai North american has authorized them to replace the engine at no cost to us. Afterwards, we brought the vehicle back complaining of 1. a noise coming from the engine compartment, and 2. a toxic smell invading the passenger cabin seemingly coming from the engine compartment. We were told that they were unable to replicate either of these conditions while the vehicle was with them. After several return visits we were told that the sound and smell were due to a failed 'motor assembly' needing to be replaced. We were charged approximately $575 despite our objectives asserting that the failed motor assembly was the result of faulty work when the engine was replaced lest the other 3 motor assemblies would also need to be replaced. We were eventually reimbursed but not my the dealership but rather by Hyundai N.a.. we again mentioned our complaint about the frequent toxic smell to Hyundai N.a. requesting that they buy the vehicle back from us based on the aforementioned conditions. We were advised that our vehicle was not eligible for buy back, rather Hyundai N.a. offered a settlement agreement for $2,000. We reluctantly accepted the settlement agreement and signed the release believing that there was no other forum for us to seek remedies except through the costly court system. We regret having accepted the settlement agreement each time the toxic smell invades the passenger cabin. After the recent news reports we are now fearful that our 2011 Sonata will burst into flames.
