2011 Hyundai Sonata: headlights failing or too dim

Filed Oct 26, 2026 · Electrical, Lights · PA

On September 24, 2026, I brought my vehicle to Kelly Hyundai Service Center for two recall repairs: IBU/BCM Anti-Theft Software Upgrade and Decal Application Anti-Theft Ignition Cylinder Protector and Decal Installation My vehicle was at the dealership all day. At the end of the day, I received a call from the technician advising me that the recall work could not be completed due to an electrical issue. When I returned home, I immediately noticed several problems that did not exist prior to the service appointment. Specifically: The high beams no longer worked. The dashboard illumination was not functioning properly. The automatic door lock system stopped working. The trunk could only be opened with the key. I contacted the service center and was informed that the only way they could determine the cause of these issues was for me to bring the vehicle back and pay a $200 diagnostic fee. I explained that I did not believe I should be charged to diagnose problems that appeared immediately after their attempted recall repair. I requested to speak with the service manager, but I was told he was unavailable. I never received a return call from management. On October 1, 2026, I returned to the service center and spoke with the manager. He recommended that I leave the vehicle for further evaluation. I did so, but later that day I received another call stating that the recall still could not be completed and that I would again need to pay a $200 diagnostic fee. I picked up my vehicle because I did not believe I should be responsible for that expense. The problems began only after the dealership attempted the recall repair and that I should not be required to pay diagnostic charges to identify or correct issues that may have been caused during that process.

On the freeway at night when headlights and back lights quit working. Got off freeway and were able to temporarily fix it. A few months later while parked in driveway and not in use for a couple of days, lights came on without our knowledge and drained our battery. Neighbor alerted us to the situation.

Once again I am having to replace a bulb for my vehicle. This will be the second time in 3 months I have had to replace my rear blinker bulb. Not including the 4-5 times per year I have to replace headlight bulbs. This time the wiring has melted and the bulb has nearly melted the lens cover. I only buy the exact OEM recommended bulb every time. Nothing fancy. Just the basic old school bulbs. Every year model around mine has been recalled for this exact issue.

This is a 'Stop Lamp Switch' issue. The car will randomly turn on the ABS light causing the ABS system to engage and not allow you to use the accelerator pedal. This is very dangerous as if you are about to merge on or off a highway the car does not allow you to correctly control your speed. This issue happens more prevalently at night time when the full beam headlights (auto or manually turn on when dark out), which is very concerning. This issue has been going on for a year now and no mechanics at Hyundai can fix or diagnose. It happened again to me this morning and came very close to causing an accident as I could not engage the accelerator pedal on a turn. Please, in the interest of safety and saving lives fix this dangerous defective part issue.

When I have my headlights turned on, and am driving my headlights flicker on and off. It mostly happens when I use the turn signal, but not always. sometimes it happens when I hit bumps. The headlights and the dash lights all go out when this happens, it usually lasts from 1 to 20 seconds at a time. I have taken it to my local garage(straight and clear) and they tested all electrical components and replaced the alternator and I still have the issue. They looked it up and determined that this is a known issue with the Hyundai Sonata, and one of the modules needs replaced in the steering column. This is a major safety issue because my headlights go out when driving and could cause and accident, and depending on the exact issue of the module it could cause a fire. There are no warning lights, just the lights go on and off. I will be getting the car repaired around November 9th 2023, because I need my car to be safe, and can submit my invoice at that time if this becomes a recall.

I have had to replace my brake lights, sometimes, every few months. My third brake light only works intermittently. Recently, my brake lights and my door lights failed to shut off after I turned the engine off. Also, my abs light came on on the dash, but after turning the engine off and back on, that light went out. After re-starting my car and repeatedly, stepping on the brake, my lights finally shut off. I checked the internet for similar problems and found out that there had been a Hyundai recall for this issue. I phoned Hyundai customer support. They told me the recall had been repaired on my car by the dealer . Obviously, it had not. (The dealer also claimed to have corrected another recall regarding seat belts, but that too is a lie, since my seat belt dash light is on although I have never been involved in an accident) I believe that the dealer billed Hyundai, but failed to either deliberately or inadvertently failed to perform the recall work. The recall involved replacing the brake stopper pad which engages the brake light switch. Obviously, Hyundai considered this a safety issue since the brake lights are always on, so the driver behind my car never knows what I'm doing. This has also affected the interior overhead light which only intermittently goes off when I close the door, so I have to keep the light in the off position.

All the electrical on the drivers side conti ues to fail. The blinker on the driver side only works if the headlights are on and the brake/blinker lights constantly go out even though the bulbs are fine.
