My family was traveling on the I-65 south interstate and the van, 2006 mercury monterey, stop responding in the middle of fast traffic. It took me by total surprise. The engine was still running. So, I initially thought it had accidently went in neutral but that wasn't the case. I tried a lower gear with not luck. Not wanting to be stuck in the middle of the interstate I then turned on my hazard…

What stands out
Owners have filed 34 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
The failure pattern owners describe
The 2006 Mercury Monterey powertrain complaints center overwhelmingly on sudden, complete transmission failure with no advance warning. Owners describe the engine running normally while the transmission abruptly refuses to engage any gear—forward, reverse, or park. The vehicle either goes into neutral unexpectedly or simply does not respond when the driver tries to shift, leaving the vehicle immobilized in traffic, at intersections, on highways, and in busy parking situations.
Failures occur across a wide mileage range, from 30,000 to 141,000 miles, with many clustering between 40,000 and 100,000. Repair shops and dealers consistently diagnose torque converter failure as the root cause. One owner reports a transmission pump failure. Some owners describe transmission slipping out of overdrive under acceleration or the vehicle revving without moving forward.
The critical pattern: Ford recalled the 2004 Freestar and 2005 Monterey for identical torque converter defects (NHTSA Actions EA09016 and Campaign 12V006000), yet the 2006 model—which shares the same powertrain—was excluded from recalls. Ford has declined repair assistance on multiple complaints. One owner had already replaced the transmission once before experiencing failure again. Repair costs run $2,250 or higher for transmission replacement, and owners note they drive the vehicle moderately (some under 10,000 miles per year), expecting longer service life than eight years.

Failure modes owners describe
Torque converter failure with loss of power/gears
Complete or near-complete loss of transmission power and inability to engage forward or reverse gears, often without warning. Typically occurs while driving at low to highway speeds. Engine remains running but transmission does not respond to shifter input. Owners report the vehicle going into neutral unexpectedly or the transmission simply not engaging any gear despite shifter movement.
When: Reported across a wide mileage range from 30,000 to 141,000 miles; many complaints cluster in the 40,000–100,000-mile range.
Symptoms owners cite: Sudden loss of power and inability to move vehicle; Transmission will not engage forward or reverse; Engine runs but vehicle does not respond to throttle; Vehicle revs RPM but does not move; Loss of power while driving at speed (30–70 mph reported); No warning lights or warning signs in many cases
Repairs/costs cited: Repair shops and dealers identify failed torque converter; full transmission replacement cited by some ($2,250+ estimated). Some owners report mechanic advice that transmission pump failed. One owner replaced transmission once already and experienced failure again.
Recalls/TSBs owners mention: Ford recalled 2004 Freestars and 2005 Montereys for torque converter failure (NHTSA Action Number EA09016, Campaign 12V006000). 2006 model year Montereys were NOT included in recalls despite identical powertrain components and same failures reported. Multiple owners state Ford declined assistance or repair coverage. One owner noted build date of September 2005 was not covered by 2004–2005 recall window.
Transmission slipping and power loss under acceleration
Transmission loses power during acceleration or slips out of gear (particularly overdrive) while driving. Vehicle either revs without moving or experiences intermittent loss of power. Some owners report high-pitched squealing sound preceding failure.
When: Reported at 30,000–66,000 miles; one case at 141,000 miles.
Symptoms owners cite: Transmission slips out of overdrive or loses power mid-acceleration; Engine revs but vehicle does not accelerate; High-pitched squealing sound (one report); Vehicle acts as if it slipped or popped out of gear; Intermittent power loss while driving at moderate speed
Repairs/costs cited: One owner reports dealer flushed transmission with no resolution. Torque converter replacement performed in at least one case. Transmission replacement cost estimated at $2,250 by one shop.
Recalls/TSBs owners mention: One update notes dealer stated without check engine light illumination, no diagnostic was possible. No recall issued for this symptom pattern in the 2006 model year.
Transmission stalling and jumping under load
Vehicle stalls or jumps while going uphill or under acceleration. Engine continues to run but transmission loses engagement. Check engine light may illuminate. One owner experienced recurrence even after dealer repair.
When: Reported at 40,000 miles (with recurrence); one case at unknown mileage.
Symptoms owners cite: Transmission stalls while going uphill or accelerating; Vehicle jumps or lurches under load; Check engine light illuminates; Failure recurs after repair
Repairs/costs cited: Dealer diagnosis included power control module replacement, transmission rebuild, fluid replacement, and wiper cowl removal. Failure recurred after repair. Another shop identified TCC solenoid and later determined torque converter was the actual cause.
Recalls/TSBs owners mention: One owner referenced NHTSA Action Number PE10033 (Vehicle Speed Control, Power Train); manufacturer was made aware but no recall offered for 2006 model.
Transmission pump failure
Transmission pump fails, resulting in loss of hydraulic pressure and inability to engage gears. Engine remains running but no power is transmitted.
When: Reported at 40,000–115,000 miles.
Symptoms owners cite: Sudden loss of power and gears; Engine revs with no vehicle movement; Transmission will not engage any gear
Repairs/costs cited: Mechanic diagnosis of pump failure. One case reports pump shaft failure requiring replacement; vehicle was repaired at approximately 115,000 miles.
Engine stalling due to power control module defect
Repeated engine stalling attributed to a defective power control module. Limited detail provided in narrative.
When: Mileage not specified.
Symptoms owners cite: Repeated engine stalling
Transmission solenoid failure
TCC (torque converter clutch) solenoid identified as potential cause of jumping and noise, though diagnosis often led to discovery of underlying torque converter failure.
When: Reported around 68,000+ miles.
Symptoms owners cite: Vehicle jumping while driving; Noise when pressing gas pedal; Clanking noise from transmission
Repairs/costs cited: TCC solenoid was replaced in one case but did not resolve the issue; torque converter was later determined to be the actual failure. Another shop cited solenoid to drive transmission as potentially faulty without confirmation.
Failure to shift into reverse or park
Vehicle fails to engage reverse or park gear and continues to drift forward. Limited detail in narrative.
When: Reported at 81,000 miles.
Symptoms owners cite: Vehicle will not shift into reverse; Vehicle will not shift into park; Vehicle drifts forward uncontrollably
Repairs/costs cited: Vehicle was not diagnosed or repaired.
