On 01/19/2021, I took my 2011 Hyundai Tucson to my Missoula, MT. Hyundai Dealership, phone (406)549-5178) for a 120,000 mile routine services, inv. # 6014023/1. A tech noticed the rear differential was leaking and the fill plug was stripped out, so, he was unable to service it without me first purchasing a new differential cover and plug ($540.00). My rear differential has never been checked or serviced since I bought the vehicle new in 2011, and I am the only owner. No one has played with the plug. How did the plug get stripped and is it a common problem for Hyundai's? I asked my service dealer how did the plug get stripped? He advised just the mileage and age of the vehicle caused it. I am suspicious of his answer. Please help me with this and if you can, inquire with the service dept. to get to the bottom of it. I feel the service tech possibly stripped the plug, but I cannot prove it. Does this regularly occur to Hyundai's? Please advise and thank you. Steven Corson, stcorson @yahoo.com
