On the 2007-2018 Ford Edge, the Power Transfer Unit (PTU) on AWD Ford Edge models is known for chronic fluid leaks from the axle shaft seals and PTU cover seal. The PTU (transfer case equivalent) lacks a drain plug and Ford originally specified "lifetime fill" fluid, leading many owners to never service it. When the seal leaks and fluid level drops, the PTU runs dry and destroys itself. Ford issued TSB 09-25-7 for 2007-2010 models, and the issue persists through 2018 with TSB 18-2255 for later versions. Seal failure typically occurs between 60,000-100,000 miles and is common in AWD models. A destroyed PTU can also damage the rear axle and differential.

This issue also affects: Acura TL, Mitsubishi Outlander, Acura CL

Common Symptoms

Brown fluid puddle under vehicle near front axle area (PTU fluid is brown/gear oil)
Grinding, howling, or whining noise from drivetrain
Vibration during acceleration, especially from stops
AWD malfunction warning light
Burning gear oil smell
Low fluid level in PTU (check port on PTU body)
Clunking on hard acceleration

How to Fix

Replace PTU axle shaft seal kit (Ford seal kit includes intermediate shaft seal, alignment washer, deflector, and seal protector tool). Complete PTU rebuild or replacement if run dry. Proactive maintenance: change PTU fluid every 30,000-40,000 miles using Ford-spec fluid (Motorcraft MERCON LV or Ford WSS-M2C938-A). PTU fluid capacity is approximately 0.5-0.8 quarts depending on year.

NoteFord says PTU is "lifetime fill" but DO NOT believe this. Change PTU fluid every 30,000-40,000 miles using Motorcraft MERCON LV. A dry PTU destroys itself quickly and a $150 fluid change prevents a $1,800+ replacement.
TipTSB 09-25-7 covers seal replacement for 2007-2010. The seal kit is available from Ford dealers. If PTU fluid looks black/burnt or metal shavings are present in fluid, full PTU replacement is needed - rebuild is not recommended.
TipCheck PTU fluid level yourself: there is a fill plug on the PTU body. Use a fluid transfer pump with a 5mm hex bit to access it. Correct fluid is Ford Motorcraft MERCON LV (XT-10-QLVC). Use OEM specification only - wrong fluid damages seals.

On the 2007-2014 Ford Edge 3.5L V6 Ti-VCT, the 3.5L/3.7L Duratec V6 in first-generation Ford Edge commonly develops timing chain stretch and variable camshaft timing (VCT) phaser rattles between 80,000-120,000 miles. The engine uses two timing chains (one per cylinder bank) that can stretch over time, causing the VCT phasers to rattle loudly on cold starts as oil pressure builds. The rattle typically lasts 2-5 seconds on startup before oil pressure stabilizes. Left unaddressed, chain slack can cause timing to jump, resulting in rough running, poor fuel economy, and potential catastrophic engine damage if a chain breaks or a guide fails.

This issue also affects: Buick Enclave, Buick Encore, Buick LaCrosse

Common Symptoms

Loud rattling noise from engine on cold start (first 2-5 seconds)
Rattle disappears once oil pressure builds
Check engine light with P0011, P0016, P0017, P0021, P0022 codes (VCT/timing correlation)
Rough idle or engine shaking
Poor fuel economy
Loss of power on acceleration
Engine hesitation

How to Fix

Replace timing chains, guides, tensioners, and VCT phaser units as a complete kit. Motorcraft timing chain kit (part number TKIT-003-MG) includes all wear components. Use full-synthetic 5W-20 oil and change every 5,000-7,500 miles to extend chain life. Labor is 8-12 hours on an Edge due to front engine access. Cost is substantially lower if done proactively vs. after a guide failure.

NoteDo NOT ignore cold-start timing chain rattle on the 3.5L. A broken guide or jumped chain can cause bent valves and catastrophic engine failure. Repair at first sign of rattle - typically $1,500-$2,500 done proactively vs. $5,000+ after chain failure.
TipUse only Ford-spec 5W-20 full synthetic oil (Motorcraft SAE 5W-20 Full Synthetic or equivalent). The VCT phasers are oil-pressure actuated and thicker oil delays oil pressure buildup, worsening rattle and accelerating wear.
TipMotorcraft timing chain kit TKIT-003-MG contains everything needed for a complete repair. Cheaper than buying individual components and ensures all wear items are replaced at once. Aftermarket Cloyes kit (9-0753S) is a well-regarded alternative.
