I replace light bulbs on my car every month if it's not the headlights, it the brake or tail light. I know a few people who own Sonatas and we all have the same problem. Being that this is an issue for more than one customer, instead of Hyundai making money off their malfunction, there should be a recall on the electrical system dealing with the lights. I have almost been run into and hit by other cars because we cannot see each other.

Good afternoon, I am contacting the Consumer Affairs department regarding the recall 180 Hyundai is conducting a safety recall in the United States to confirm the high pressure fuel pipe was properly connected by Hyundai dealers to the high-pressure fuel pump outlet when the engine was replaced under recalls 132 and 162. In come cases, during the engine replacements under recall campaigns 132 and 162, the high pressure fuel pipe may have damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe. Hyundai will notify owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's recall number for this recall is 180. My Hyundai Sonata limited was involved in an accident after Hyundai had just replaced the motor and on impact the whole car caught on fire, so what I am trying to do is find out do I need to contact NHTSA in regards to this matter but I feel that my life, the person involved in the accident was totally at risk due to this malfunction and I am out of so much and was put in a very hard financial place due to this fire when it could have been prevented. If someone could please contact me at [xxx] thanks, [xxx] VIN #: [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I never received information regarding the recalls on my Hyundai Sonata 2011 vehicle. I was driving my Hyundai Sonata 2011 on 4/11/19, going about 60 miles an hour and the cut shut off. Was in heavy congested traffic and I was almost rear ended with no control of the Hyundai Sonata 2011vehicle. My Hyundai Sonata 2011 was moved to the side of the road where a tow truck was called. Subsequently, Hyundai Sonata 2011was taken to the huntington dealership. Dealer informed me there was 7 recalls of which I not aware of in regards Hyundai Sonata 2011 this could have been a life threaten situation and Hyundai should notified me of all recalls. This is unacceptable and life threating to family friends and community.

The drivers side rear light bulbs keep on going out. Have changed them about ten times in one year! I cannot change them anymore as the plastic casing has morphed by the heat of the fuse connector to the bulb! there are two bulbs rolling in the casing as they came off when trying to extract and replace. Also I have never had any lights illuminate on my dashboard, even when my engine was knocking due to shavings in engine (that was replaced, thank you). Lastly, had to replace my shocks and struts this year and was told by mechanic at big O tire that they contacted Hyundai directly as they ran into an issue with replacing what should have been correct struts. They were told this particular car with associated VIN has the 'goofy' struts!!! I'm sorry but I didn't pay a goofy price for the car!

"power assist recall/air bag recall" the electrical power steering in my car has created a problem when driving on the interstate. The cost to repair the car is in excess of $1200 new and $600 or more used. The electrical panel in the car is not completely functional either. I have problems with power windows and locks. There have been a total of more than 10 recalls on this particular model vehicle. I cannot afford to repair or purchase another vehicle. When I investigated further this was the latest issue listed. Steering:electric power assist system recall summary: Hyundai motor company (Hyundai) is recalling certain model year 2011 Sonata vehicles manufactured December 11, 2009, to October 31, 2010. In the affected vehicles, the electronic power steering (eps) circuit board may be damaged and result in a loss of power steering assist. In addition there are several air bag recalls on the vehicle. Including the following: Frontal air bags, seat belt pretensioners, and side air bags are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.

The car has a major electrical flaw, I keep getting recall letters but the one thing no one has mentioned is the grounding. After numerous electrical issues. I ran a parasitic draw test on the system. The grounds are non existent. The car has no good grounds at every point of ground there's no metal. They grounded the car to painted surfaces. This is a major flaw that is causing I would guess the majority of the issues in electrical failures. My brake lights would not turn off. Ever. No matter if the the car was off or on. The recall work was done by Hyundai and when I contacted them to plead with them to please recheck it they flat out refused saying the work has already been done. I was left with no choice but to try and determine the issue. My car started without pressing the brakes. I could shift and out of park and reverse without pressing the brakes. I drove around with my brakes illuminated all the time. Then they just quit working since the bulbs burnt out when the housing for the bulbs melted. The car suffered the known engine failure issue but the electrical started long before this. The grounding is not sufficient. Period these cars are a major hazard and should all be taken off the road. I have photographs off the electrical bulb holders that melted. I've included photos of the way it's supposed to look and the melted one. The one bulb was so burnt I had to break it out of the holder.

Headlights and brake lights, they will not work, put in brand new bulbs, they light up for about five mins. Then stop working, cannot get a bulb to work, it seems the electrical parts of the lights are not working properly. This is bringing me a lot of problems, cops pull me over for no brake lights, but I can't get them to work>>>>>

The contact owns a 2011 Hyundai Sonata. The contact stated that the driver's side window failed to go up and down when the function button was pressed on the door. The contact had to apply force to the area near the window to get it to slowly go up and down. In addition, a chime was heard each time the front driver and passenger seat belts were secured, and a warning indicator illuminated for the seat belts. The vehicle was not diagnosed or repaired. The vehicle was included in NHTSA campaign numbers: 17V617000 (seat belts) and 18V137000 (seat belts, air bags) as well as service campaign number: 953 (ECM & cluster update-engine monitoring logic product improvement).

We have had nothing but problems with our 2011 Hyundai Sonata. Less than a year ago our engine completely died while driving the vehicle. The dealership replaced the engine and since then we have had starting and electrical problems. When we went to pick up the car it didn't start right away and they told us we needed a new battery. We bought a new battery and about a week later it still wouldn't start on and off. Since we had the engine replaced, we have had to change the headlights and brake lights 4 times! we believe that when the engine died it caused an electrical issue. Fast forward about 9 months and now the car has 3 engine codes. P0017 P0014 and P0560. Crankshaft and camshaft position sensors and a system voltage malfunction. We will never buy a Hyundai again! they claim they totally replaced the engine but now I wonder if they salvaged old parts in the new engine and what exactly happened to the electrical system when the car shut off while driving.

I drove my 2011 Hyundai Sonata on the highway, while trying to accelerate my vehicle to match the flow of traffic I noticed that the vehicle would not accelerate past 40 mph. I pulled my vehicle over to the break down lane and engaged hazard lights. I released the hood latch and opened hood to engine compartment. I saw smoke and could smell burning plastic. I checked my oil levels and did a quick inspection of fluid levels. When I tried to restart my car the vehicle would not start. I had the car towed to a mechanic, the mechanic stated that the starter was burned out. He replaced the starter and when attempting to start the car the new starter began to smoke as well. He stated that it was good that I pull the car over so quickly cause the car could have caught on fire. This happened recently and he has stated it will require further investigation but he is pretty sure the engine has seized.
