After the front engine cover leak was fixed, they pressure washed the engine compartment, looks new. But now I have exhaust smell on hard acceleration. My 2018 already came with the recirc software update and I looked all over the underside and firewall so see if some seal or tape was missing or torn, (maybe from pressure washing). Called dealer, they said maybe smell from the new gasket material, give it some more time (??). Drove it for 800 miles, smell never went away. Kept thinking about why did it start after the repair, I never had any smell before. Finally one night I thought of checking the oil level. Sure enough overfilled. Drained 1/2 quart out, now normal fill line, and no more exhaust smell in the cabin. I won't say it....
