NHTSA Complaint #11611510 — 2017 FORD ESCAPE

Started vehicle to run errands and it immediately began rough idling and the check engine light began flashing. Read the manual, immediately returned home and parked it. Made appointment with dealer. Dealer reproduced the problem and verified the concern. Dealer ran diagnostic which returned codes P0304 and P0316. Dealer found cylinder 4 misfiring. Dealer swapped ignition coils from 3-4. Misfire stayed on cylinder 4. Dealer swapped spark plug on cylinder 4. Misfire on cylinder 4 cleared up. Dealer noted coolant was not low and confirmed we had not added any. We did have it at that same dealer on 6/7/24 for oil change service which included multipoint inspection and fluid top off. Our paperwork does not note whether coolant was topped off during that service. Dealer gave us an estimate to replace the spark plugs which we approved. Dealer held the vehicle overnight to repair the following day. After sitting overnight, dealer checked cylinders for coolant. Dealer found coolant leaking into cylinder 4. Dealer revised original repair estimate. Vehicle does not need spark plugs, vehicle needs long block assembly replaced. We declined repairs at this time. Repair cost estimate $8585.03.
