Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin supersedes 26-2194. Reason for update: update the Parts list to correct a part description " Loctite 638", update the claim quantity for the drain/fill plug, update the claim quantity of the wheel hub bolts (Corsair) and limited the parts list for Edge/Nautilus to only the rear drive unit fluid. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder chatter condition, most noticeable at low speeds turning No relevant diagnostic trouble codes (DTCs) present This may be due to internal rear drive unit (RDU) fluid contamination.

The failure pattern owners describe
Owners describe a transmission that's unreliable in stop-and-go traffic and takeoff situations. The car jerks, bucks, and hesitates during acceleration; several report it won't respond when expected. Some experience hard shifts and stuttering, others hear humming followed by slow movement then jerking. One owner's transmission revs to 3,000 RPM when braking and fights them at red lights. Another reports torque converter chatter and excessive slippage; a third's transmission simply stalled after stopping at a traffic light.
The problem is frustrating because diagnostics come back clean—no warning lights, no codes in most cases. Dealerships have told owners it's "normal," software issues, or "adaptive learning," even when owners have had multiple visits. One transmission replacement didn't solve the problem. Lincoln refused coverage in at least one case despite the vehicle having the same transmission type as a recalled model, and offered a buyback that was later downgraded to ten free oil changes.
One severe case involved uncontrolled forward acceleration when reverse was selected, unresponsive brakes, and a crash through a fence into a neighbor's garage—though this incident's root cause remains unclear. A separate owner also reports transmission fluid was low six months before failure but the dealership didn't follow up.
Early failures appear within weeks of purchase for some; others emerge around 75,000–94,000 miles.

Failure modes owners describe
Erratic transmission response and torque converter issues
Transmission fails to respond reliably at low speeds and in stop-and-go traffic; revs inconsistently, jerks, bucks, and hesitates during acceleration. Multiple owners report uneven revving, hard shifts, and stuttering. One owner experienced torque converter chatter and excessive slippage; another reports revving to 3,000 RPM when braking. No warning lights appear in most cases despite failure.
When: Low speeds, stop-and-go traffic, takeoff from stops (35–45 mph range); some issues noted within weeks of purchase; some at 75,000 miles; one at 94,000 miles; one at 487,000 miles
Symptoms owners cite: Jerking and bucking, especially under 40 mph; Hesitation and slow response during acceleration; Hard shifts and stuttering; Inconsistent revving, revving to 3,000 RPM when braking; Transmission not responding at low speeds in traffic; Torque converter chatter and internal slippage; Humming noise followed by slow movement and jerk on acceleration; Auto Hold malfunction
Codes mentioned: U3003-16 (Battery Voltage Below Threshold—unrelated to transmission, reported in uncontrolled acceleration event)
Repairs/costs cited: Transmission replacement ordered and completed in at least two cases; however, symptoms persisted after replacement in one case. Torque converter diagnosed as bad in one case; internal fault with excessive slippage and torque converter chatter in another. One owner's warranty company verified transmission needed replacement. Dealer diagnostics have returned 'no codes' or 'no issues found' in multiple cases despite clear symptoms.
Recalls/TSBs owners mention: Lincoln offered buyback in one case but changed offer to 10 free oil changes. One owner's VIN not included in 2021 transmission recall despite having same transmission type and same issue. Some owners report dealership claims that 10-speed transmissions are known to be problematic.
Stalling and no-start after stopping at traffic lights
Vehicle stalls or fails to accelerate after coming to a stop at traffic lights or stop signs, leaving owner stranded and concerned about rear-end collision risk.
When: At traffic lights and stop signs after braking to a stop
Symptoms owners cite: Vehicle stalls after stopping at a traffic light or sign; Car will not accelerate when trying to move away from stop light or stop sign; Lack of responsive brake pedal reported in one uncontrolled acceleration incident
Repairs/costs cited: One owner reports that dealership, after multiple visits, concluded the issue is 'normal' and nothing is wrong. No repair attempted or confirmed successful.
Uncontrolled acceleration and brake failure
Vehicle accelerated forward when reverse was engaged, brake pedal was unresponsive, and vehicle crashed through fence and into neighbor's garage. This incident resulted in significant property damage.
When: One incident reported on wet road surface during rain
Symptoms owners cite: Vehicle accelerated forward when reverse button pressed; Engine revved; Brake pedal not responsive; Continued forward motion despite brake attempts
Codes mentioned: U3003-16 (Battery Voltage Below Threshold)
Repairs/costs cited: Vehicle damage estimate $1,485.25; fence damage $2,560; neighbor's garage damage $8,000. Dealer EEC test on Oct 14, 2025 reported 'no codes in any systems.'
Soft or leaking transmission fluid
Low transmission fluid level detected during routine service inspection; dealership failed to address at that time, and issue was not followed up for six months, contributing to eventual transmission failure.
When: Detected six months before transmission failure diagnosis
Symptoms owners cite: Low transmission fluid level
Repairs/costs cited: Dealership notified of low fluid level but was 'backed up' and failed to contact owner as promised.
EVAP system and fuel pump control issue
Fuel pump shuts off prematurely during refueling, requiring repeated repositioning of nozzle. Owner suspects possible relationship to transmission issue.
When: Ongoing during complaint period
Symptoms owners cite: Fuel pump stops after a couple of dollars; Nozzle repositioning required to continue refueling
Repairs/costs cited: Owner planned to request diagnostic on EVAP system.

I bought my 2020 Lincoln nautilus in February 2025 soon after I noticed a jerking from my lower gears,it has 80000 miles.i took it to the dealer I bought it from and they said the transmission is falling and will cost $10,188 to replace. They told me there was no recall and it wasn't covered under any warranty.

My 2020 Lincoln Nautilus has an intermittent jerk during light acceleration with no diagnostic codes. This was confirmed when I had a professional mechanic drive it.
While driving low speed between 1-55 mph my car feels like it’s stuttering, jerking or about to shut down.
I’ve only had the car 2 weeks brought brand new from Crest Lincoln on May 28,2020. Every time I try to accelerate the car doesn’t want to move , it sounds like it’s trying to get power. It makes a humming noise then it slowly starts to move and the care jerks and pick up speed. I don’t like it, I’m afraid that when i come to a light and it doesn’t accelerate I might get hit from behind. I…
