Lincoln
Navigator

The collision warning doesn't warn sometimes. Nothing goes off when Im approaching and or have slammed on my breaks to avoid a collision. Sometimes it goes off at a great distance when it doesn't make sense to go off. I just bought the car used and have noticed this a lot. Also sometimes lane departure corrects and sometimes it doesn't. Something is off.

Catastrophic engine failure on 2020 Lincoln Navigator at 93,000 miles. Oil contamination in cylinder 6 caused complete compression loss due to piston ring failure. The engine suffers from failed cam phases and excessive carbon build up which are known failure points of this engine. Ford Technical Service Bulletins 20-2423 and 23-2143 document this as a known manufacturing defect for vehicles in my build timeframe, proving Ford was aware of this problem before production. This is premature engine failure requiring complete engine replacement on a 5-year-old vehicle. The failure pattern matches ongoing class-action lawsuits against Ford for EcoBoost engine defects. Safety concern: Catastrophic engine failure without warning while driving creates risk of sudden loss of power and potential accidents. Lincoln customer service has admitted these vehicles have this issue but refused escalation despite documented manufacturing defect and broken multiple callback promises. Request NHTSA investigation into 2020 Lincoln Navigator 3.5L EcoBoost engines for premature piston ring/compression failures related to carbon buildup and failed cam phasers as documented in Ford's own service bulletins.

Category: Power Train -> Automatic Transmission Subject: 2020 Lincoln Navigator – Repeated Missed Warranty Repairs – Transmission Neutral-Out & Violent Downshift at Highway Speed Description: On [XXX], while traveling at approximately 70 mph on [XXX], my 2020 Lincoln Navigator suddenly downshifted, free-wheeled into neutral, then violently re-engaged into a lower gear, chirping the rear tires and nearly causing a collision. The vehicle displayed a "Shift System Fault" warning. This defect matches TSB 23-2120 (momentary neutral-out) and TSB 24-2101 (harsh/delayed engagement) for the Ford/Lincoln 10R80 transmission used in the Navigator. TSB 23-2123 (harsh/delayed engagement/shift) also applies to my model year and transmission. I purchased this vehicle in December 2023 from Performance Lexus RiverCenter (Covington, KY) with the original Lincoln 6-year/70,000-mile powertrain warranty still in effect. According to Carfax, the vehicle was owned by Airport Ford, a Ford/Lincoln dealer, for six months prior. No transmission-related repairs were performed during that period despite applicable TSBs. In March 2024, I reported abnormal shifting to Lincoln of Cincinnati. The concern was dismissed without inspection or repair, even though the TSBs applied to my VIN at that time. The [XXX] incident is the direct result of two separate failures by Lincoln/Ford dealerships to act on a known defect while the vehicle was under warranty. This is a serious safety hazard that can cause sudden loss of power and traction at highway speeds. Vehicle Details: - Year: 2020 - Make: Lincoln - Model: Navigator - Transmission: 10-speed automatic (10R80) - Mileage at Incident: 48000 - VIN: [XXX] - Date of Incident: [XXX] - Dealers Involved: Airport Ford (prior owner), Lincoln of Cincinnati (service visit March 2024) The dealer is working on the car currently will send any repair items when they are in hand INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Had transmission problems before this final issue. With that said the dealership ended up replacing the transmission as it was under warranty. Not even 2000 miles later we are coming back from vacation and I lost total power of the vehicle but since I was going around 70 mph we made it to the shoulder of the highway. Once there the vehicle was already smoking so we all got out of the vehicle and that’s when I saw the fire, and not even 3 minutes later it was totally in gulfed in flames.

The transmission system failed, causing jerking during acceleration. The original transmission was replaced by the dealer, so it may be available for inspection if retained by the dealer or returned to Ford/Lincoln. Jerking during acceleration can create safety risks including: unpredictable vehicle behavior during merging or passing, potential loss of control in traffic situations, and compromised ability to maintain consistent speed or smoothly accelerate away from hazards. Yes - the dealer confirmed the problem and determined the transmission required replacement, indicating they reproduced and verified the issue. Ted Britt Ford Lincoln, Chantilly, VA inspected the vehicle. No dashboard lights.

Was on Interstate when there was a loud bang, the transmission shifted harshly and I lost power where the vehicle would not go faster when i hit the pedal. I was basically pumping the gas for about 3-5 seconds before transmission re engaged. It was a dangerous situation in that I was at highways speeds about 65-70mph and i had no throttle control for several seconds. There was no warning when it happened and it re engaged and I was able to drive the vehicle home. Ford did replace the CDF drum under warranty but there should be a recall on this transmission. The the same thing happened in my other truck, an f150 which uses the same tranmission and engine combo.

My car has an unknown electrical issue that causes the car battery to completely drain and the car unable to turn on. It first started in August 2023 and after months of time at the dealership, Lincoln has never determined the cause or been able to fix it and it continues to happen. This is unsafe because it leaves me and my family stranded with no operable car.
