I was at South Hyundai dealer ship located in Edmonton. I was there in OCT for my full service and after that service i noticed a grinder sound in my car every time i press gas so i went back again last month NOV. I explained them there is grinder sound coming from my car every time i press gas. They took my car and after the diagnosis, they said we did all the tests. There is nothing wrong with my car, it was lot of snow built under and charged me $129 and now this month Dec, grinder voice is even worst. My cousin who is mechanic looked at my car and showed me exhaust fan is broken, thats where the sound is coming from. This dealership charged me for not fixing anything and condition is more worst. I have been getting headaches while driving, he said i could be breathing in carbon monoxide and is extremely dangerous. I want someone to take action regarding my concern. I want them to fix my car and refund my money.
