NHTSA Complaint #11529461 — 2018 FORD EXPLORER

Have had the vehicle for less than a year have had nothing but lil problems but recently have gotten a cranking noise, transmission / coolant leaking under the vehicle. Also have water leaking from the exhaust line when car is in park. Driving back from work early in the morning a sounded like a big pop not sure what it have may been took it to the mechanic ass well twice an got it diagnosed an they’re response was they couldn’t find the problem. The area I’ve seen an heard the clunking the most would be under the vehicle at the center by the catalyst converter. Transmission jerks as well I’ve had this vehicle for 8 months a don’t seem to be what a vehicle should be doing.
