The 2008 Taurus (Five Hundred rebadge) with the 3.5L Duratec V6 is mechanically solid overall, but transmission cooling failures and water pump-driven timing chain issues create catastrophic risk if ignored. Budget for preventive fluid maintenance.
Transmission Oil Cooler Failure Leading to 'Strawberry Milkshake of Death'
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Transmission fluid appears pink or milky in the reservoir, Coolant looks brown or has oily sheen, Harsh shifting or slipping between gears, Transmission overheating warnings
Fix: Internal transmission oil cooler in the radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, complete transmission flush (often multiple cycles), and frequently full transmission rebuild because coolant destroys clutches and valve body. If caught early (first sign of mixing), radiator + external cooler install + flush runs 6-8 hours labor. If delayed, add transmission rebuild at 12-16 hours.
Estimated cost: $800-1,200 if caught immediately, $3,500-5,500 with transmission damage
Water Pump Failure (Timing Chain Driven)
Common · high severity
Typical onset: 90,000-130,000 mi
Symptoms: Coolant weeping from timing cover area, Overheating especially at idle or low speed, Rattling or grinding noise from front of engine, Coolant loss with no external puddles
Fix: The water pump is driven by the timing chain inside the engine, so failure means removing timing cover, chains, and guides. This is not a quick roadside fix. Requires cam alignment tools and complete timing system inspection while open. Book time is 8-10 hours, though experienced techs can do it in 7. Always replace timing chain tensioners and guides while in there.
Estimated cost: $1,800-2,800
Throttle Body Carbon Buildup and Idle Issues
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Rough or surging idle, especially when cold, Stalling at stoplights after highway driving, Check engine light with P0506 or P0507 (idle control codes), Hesitation on light throttle tip-in
Fix: Electronic throttle body accumulates carbon on the plate and bore, preventing smooth idle control. Remove and clean throttle body with proper solvent, replace intake gasket. Requires throttle relearn procedure after reinstall. 1.5-2 hours labor. Sometimes needs new throttle body if motor is failing.
Estimated cost: $180-350 for cleaning, $450-650 if throttle body replacement needed
Front Transmission Mount Failure
Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunk or jolt when shifting from Park to Drive or Reverse, Excessive vibration at idle in gear, Engine rocks visibly when revving in Park, Knocking sound over bumps from engine bay
Fix: Hydraulic front transmission mount separates or leaks fluid. Requires supporting the engine/trans assembly from below, removing mount bolts, and replacing. Not difficult but time-consuming due to access. 2-2.5 hours labor. OEM mount strongly recommended over aftermarket.
Estimated cost: $350-550
Power Steering Pump Whine and Leaks
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Whining or groaning noise especially during cold starts or turns, Power steering fluid leaking from pump or high-pressure line, Intermittent heavy steering effort, Fluid level repeatedly low
Fix: Pump shaft seals leak or internal vanes wear. High-pressure line to rack can also weep at crimps. Pump replacement is straightforward: 2 hours labor. Often worth replacing pressure hose at same time if original. Flush system after pump replacement to clear debris.
Estimated cost: $400-650 for pump and labor, add $150-200 if doing pressure line
Lower Control Arm Bushing Deterioration
Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Clunking over bumps or during braking, Steering wander or vague feel on center, Uneven or rapid inner tire wear, Visible cracks or tears in control arm bushings
Fix: Front lower control arm bushings separate or crack, especially the rear bushing. These cars eat front bushings due to weight. Ford doesn't sell bushings separately, so you replace the entire control arm assembly. 2-2.5 hours per side, always do both sides and get alignment after. Ball joint typically fine unless heavily neglected.
Estimated cost: $500-750 for both sides including alignment
Fuel Filter Clogging (Returnless System)
Rare · medium severity
Symptoms: Hard starting especially after sitting overnight, Hesitation or stumble under acceleration, Loss of power at highway speeds, Check engine light with lean codes (P0171/P0174)
Fix: Inline fuel filter restricts flow when clogged. Often overlooked because it's hidden under vehicle near fuel tank. Ford calls it 'lifetime' but that's optimistic with poor fuel quality. Filter replacement is 0.8-1 hour, but requires depressurizing fuel system and dealing with quick-connect fittings that can be brittle. Consider replacement every 60k-80k as preventive.
Estimated cost: $150-250
Owner tips
Install an external transmission cooler immediately and bypass the radiator's internal cooler — cheap insurance against the mixing failure
Check coolant and transmission fluid color every oil change; early detection of mixing saves thousands
Budget for water pump replacement around 100k miles as preventive; waiting for failure risks overheating damage
Use Motorcraft Mercon V fluid only in the transmission; wrong fluid accelerates valve body wear
Clean throttle body every 30k miles to prevent idle codes and carbon buildup
Solid drivetrain if you prevent the two killers (trans cooler and water pump); buy one under 80k miles or with documented preventive work, avoid high-mileage examples without service records.

Ford Motor Company (Ford) is recalling certain model year 2009-2012 Ford Flex, 2008 and 2010-2012 Ford Taurus, 2008-2009 Ford Taurus X, 2008 Mercury Sable, 2009 and 2011 Lincoln MKS vehicles. The driver frontal air bag may improperly inflate during second-stage deployment in the event of a high speed crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Consequence: An improperly inflated air bag increases the risk of injury in the event of a crash.
Remedy: Ford will notify owners, and dealers will inspect and replace the driver's frontal air bag module, as necessary, free of charge. The recall is expected to begin on June 13, 2016. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16C06.
