Power train

8 reports
“Transmission was shuddering when it shifted gears. It would lose power and jerk between each gear. We paid for diagnostic at the dealership and they diagnosed as torque converter shudder under 2 separate TSB's. Dealership offered to fix at a cost of $6400. Told not to drive the vehicle or at least as little as possible. They refused to cover this under the TSBs. Contacted Lincoln Client Care. The shudder became worse even driving through town and it would jerk and the RPMS were jumping all over. Also took it to AAMCO after dealership stated they would not cover it under a TSB. AAMCO provided free diagnostic and came to the same conclusion of the torque converter and estimated cost of $3300, which was 3100 less than dealership. Asked Lincoln for goodwill fix and they spent a month talking to the dealership trying to get the dealership to a lower price, to whichthe dealership raised the price to $6800 and they offered 4k in goodwill, but said that it would take 4 to 6 weeks to get the parts. By this time AAMCO already had the parts after waiting3 weeks on backorder and AAMCO made te fix at an out of pocket cost of $3300. Total out of pocket costs were the 300 for…”

“2021 Lincoln Nautilus Reserve 2.7-liter twin-turbocharged V6 with coolant intrusion caused by a blown head gasket on cylinder #6.

The issue progressed and was taken to the shop a second time. The issue was found from a misfire code on cylinder #6. Vehicle is currently being repaired.”

Electrical system

3 reports
“Vehicle died in parking lot. The electronics all worked, it just would not start and would not go into any gear. Had to have it towed to dealer for repair. They replaced the PCM but it still would not start. They again replaced the PCM and a fuse. The vehicle started. This is the FOURTH time for the exact same issue. It died twice on the previous owner, once while on the highway. It also died twice for the mechanic while trying to diagnose / test drive the unit for the previous owner. We were lucky it died where it could be towed as it's an all wheel drive unit. It has also had an O2 sensor replaced, and the previous owner suffered wiring issues (replaced the engine bay body harness), sunshade recoil failed, abnormal noise in rear end when turning, etc. All issues were corrected. However, I am uncomfortable that these issues may re-occur. Another failure of the PCM and/or electrical issue could cause the unit to die in a situation that could be life threatening.”
