10/26/22 My taillight was out. I bought a new bulb but was unable to replace the bulb since the wiring harness was warped/damaged from overheating. The dealership quoted me 463.00 to repair this issue. I explained that in 2020 I had same issue. The dealership charged me 254.48 to fix. I opened a case with Hyundai Corporation case# 17586266. After a lot of effort on my part they did send me a check. This new re-occurring issue I opened case 20500590 and the dealership or corporate would not take any ownership.
Many complaints online with others having same issue of melted wiring harness and replacing taillights multiple times in one year. I located the part on amazon for much cheaper than Hyundai quoted me and had a friend install. Not sure how long this will last. What is causing these wiring harnesses to melt? Clearly a safety issue if a fire starts! Extremely disappointed in Hyundai dealerships, Corp and in this 2011 Sonata. POS car! Don't buy one!
