Had this service done at my dealer, after arriving home I parked car in garage. About 30 mins later I had to go into garage to get something and there was a overpowering smell of chemical in closed garage. It gave me a headache it was so strong I could not stay near car inside garage. Was something spilled ? What could cause this? Can this cause damage to other parts of engine? I moved the car outside where it still is. I also had a Hyundai ordered FREE rust corrosion applied under the car due to high salt used in my area. I called dealer and the guy said "oh something just spilled on hot part" park the car outside overnight and it will dissapate. I am afraid this "spill" could have been the mechanic not shutting off some kind of valve before starting. I was told the undercarriage stuff would not cause odor. I DON'T BELIEVE THEM. I have not driven the car yet again since last nite. it is very cold here today, there is no odor in garage now. Your thoughts on this? THANK YOU
