While driving through an intersection at approx 40 MPH transmission shutter and locked the wheels up. Luckily the traffic around me was able to Dodge me without incident. I shut it off and restarted put into 1st gear and pulled off to side of road. There was burnt gear oil smell coming from under the SUV. Now it comes and goes trans slipping and ptu overheating.

What stands out
Owners have filed 265 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.
Among the 18 model years of Ford Edge in our records for powertrain problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2008 Ford Edge has widespread transmission issues—hard shifts, loss of power, and sensor failures that leave drivers stranded in traffic and on highways—often striking without warning and frequently returning after dealer repairs. Budget for expensive transmission work even on low-mileage examples, and expect frustration getting dealers to diagnose or cover repairs once warranty expires.
The 2008 Ford Edge powertrain complaints cluster around two major patterns: transmission engagement failures and sensor signal loss causing loss of power.
Transmission engagement trouble shows up as hard jerking between gears—especially when shifting from park or during acceleration—accompanied by loud clunking or banging noises. Owners report the transmission seeming to slip out of gear, leaving the engine revved at high RPM while the car crawls forward or barely moves. This happens during normal driving, stop-and-go traffic, and highway merges. Restarting the engine temporarily fixes it.
Sensor failures trigger warning lights (wrench, check engine, airbag, tire pressure), ODO data errors, speedometer drop to zero, and sudden loss of acceleration. The output shaft speed (OSS) and turbine shaft speed (TSS) sensors are cited repeatedly. Owners lose power mid-traffic or highway driving, forcing hazardous pullouts. Dealers report finding metal shavings in transmission fluid and point to Ford Service Bulletin 07-21-11 and 103100. Some cite firmware/computer upgrades and sensor replacements costing $800–$1,700 as fixes, though owners report recurring problems.
Secondary issues include stalling while driving or reversing, rear bearing wear at low mileage, transmission fluid leaking onto exhaust (fire hazard), and electronic throttle body failures. Dealers frequently cannot reproduce symptoms or find codes, leaving owners unrepaired or out of warranty. Many reference online forums showing this pattern across numerous 2008 Edges and nearby model years.

Failure modes owners describe
Transmission hard shifts and jerking
Transmission engages with violent jolts and loud clunking when shifting from park to drive, during acceleration, or at low speeds. Engine RPM spikes but car barely moves or slows unexpectedly. Feels like rear-end collision.
When: 39,000–165,000 miles; varies from first months of ownership to later in vehicle life
Symptoms owners cite: Loud clunking or banging when shifting gears; Hard jerking of entire vehicle during gear engagement; Engine revs high but car accelerates slowly or not at all; Transmission feels like it slips out of gear; Vehicle lurches forward after delay; Rough, lagging shifts between gears
Codes mentioned: P0715 (Turbine Input Speed Shaft Sensor), Wrench/powertrain malfunction light, Check engine light (some cases)
Repairs/costs cited: Owners cite transmission rebuilds ($4,000+), transmission fluid flush/replacement, and adaptive transmission file deletion/upload. Dealer reprogramming and updates attempted; some require multiple shop visits. Metal shavings found in transmission fluid in at least one case.
Recalls/TSBs owners mention: Ford Service Bulletin 07-21-11 and 103100 (4/24/13) referenced by owners; TSB 07-21-11 addresses OSS/TSS sensor issues. Some dealers stock parts for repair. Dealers deny warranty coverage in some cases despite TSBs.
Loss of power and acceleration with sensor/code failures
Without warning, vehicle loses ability to accelerate properly or at all. Engine revs but car crawls or refuses to move forward. Multiple warning lights illuminate simultaneously (wrench, check engine, airbag, tire pressure). Speedometer drops to zero; odometer displays dashes or 'ODO DATA ERROR' message. Occurs on highway and city streets at all speeds.
When: Around 70,000–96,000 miles (commonly reported cluster) but also as low as 39,000 miles; can happen early in ownership or after several years
Symptoms owners cite: Sudden loss of acceleration power while driving; High engine RPM but minimal forward movement; Speedometer reads zero despite moving; Odometer shows dashes or 'ODO DATA ERROR'; Wrench light, check engine light, airbag light, tire pressure warning illuminate together; Vehicle feels stuck in high gear; Loud bang or jerk when problem occurs; Hesitation and jerking when accelerating from stop
Codes mentioned: Output Shaft Speed (OSS) Sensor fault, Turbine Shaft Speed (TSS) Sensor fault, P0715 (Turbine Input Speed Shaft Sensor), ODO DATA ERROR message, Wrench/powertrain malfunction light, Check engine light, Airbag light, Tire pressure monitor fault
Repairs/costs cited: OSS and TSS sensor replacement cited most frequently (cost $370–$1,700 depending on labor). Firmware/software update and computer reprogramming reported. One owner had PCM (main computer) replaced along with all 6 ignition coils and spark plugs ($3,000). Dealer diagnosis difficult because warning lights and codes often clear after restart, leaving no evidence for technician to scan.
Recalls/TSBs owners mention: Ford TSB 07-21-11 addresses OSS/TSS sensor shorts. Owners state Ford has a Customer Satisfaction Program for electronic throttle body (ETB) extending coverage to 10 years/150,000 miles (except 2008 model year refused coverage). TSB 103100 (4/24/13) referenced. Ford acknowledges issue exists but refuses recall.
Stalling while driving or reversing
Engine stalls unexpectedly during driving, reversing, or at traffic lights. Occurs without pattern or warning. Vehicle barely restarts or stutters to start. Idle jumps and dips erratically.
When: Random, unpredictable timing; one owner reported 4 stalls within short period
Symptoms owners cite: Engine stalls while driving forward; Engine stalls while reversing into parking spot; Engine stalls at traffic light; Stalling on highway (65+ mph); Difficult restart; vehicle barely turns over; Stuttering, rough start; Tachometer jumping and dipping at idle without driver input
Repairs/costs cited: No specific repairs mentioned for stalling. One owner suggested possible issue with fuel system or ignition based on symptoms.
Front wheel bearing failure
Front wheel bearings wear prematurely, causing loud whining or grinding noise that progressively worsens. Noise audible over radio and conversation. Design flaw allows water to enter bearing housing, causing corrosion of inner and outer races and ball bearings.
When: Around 78,000–93,000+ miles on relatively low-mileage vehicles with highway driving only
Symptoms owners cite: Loud whining noise (initially thought to be tire noise); Loud grinding noise at highway speeds; Noise progressively worsens over time; Noise audible over radio and conversation
Repairs/costs cited: Complete front wheel bearing replacement required. One owner's repair cost $550 for bearings; another incurred $500 for new Michelin tires before bearing diagnosis. Corrosion visible on ball bearings, bearing race, and grease when parts inspected.
Recalls/TSBs owners mention: Powertrain warranty may cover if vehicle is first owner and still in warranty period. Warranty denied to non-original owner in one case despite other warranties being honored.
Transmission fluid leak onto exhaust (fire hazard)
Transmission and transfer-case leak fluid directly onto exhaust manifold and around the area. Professional identified as severe fire hazard. Rear main engine oil seal also leaking in same vehicle.
When: Pre-purchase or shortly after purchase of used vehicle
Symptoms owners cite: Transmission fluid leaking from case; Transfer-case fluid leaking; Fluid dripping onto hot exhaust manifold
Repairs/costs cited: Owner reports transmission shop stated leaks had been ongoing for considerable time before purchase. Used vehicle purchased October 2015 already exhibited this condition. Repair timeline extended (4+ weeks), owner incurred over $300 in gas for loaner vehicle.
Recalls/TSBs owners mention: Ford deferred responsibility to dealership, claiming dealership is responsible. Dealership denied warranty coverage (claimed as-is sale despite purchase agreement stating warranty coverage). Owner reported three separate complaints to Ford Motor Company about fire hazard with no satisfaction or results.
Electronic throttle body (ETB) failure causing loss of power
Electronic throttle body fails, causing sudden loss of engine power and entry into 'limp mode' (reduced power mode). Accelerator no longer responds or responds only partially.
When: 104,000+ miles
Symptoms owners cite: Check engine light and wrench light illuminate; Sudden loss of power while driving; Vehicle enters limp mode (reduced power); Accelerator unresponsive or sluggish; Power returns but only at ~5 mph
Repairs/costs cited: ETB replacement cost over $750. Ford issued a Customer Satisfaction Program extending ETB warranty to 10 years/150,000 miles for most vehicles, but owner with 2008 Edge at 104,000 miles was denied coverage because Ford deemed the vehicle too old and mileage too high.
Recalls/TSBs owners mention: Ford Customer Satisfaction Program issued extending ETB warranty to 10 years/150,000 miles, but excludes 2008 model year or denies based on mileage. Ford acknowledged problem exists in models as far back as 2005.
Ignition coil and PCM (engine computer) failure
Multiple ignition coils fail, causing engine misfire, rough running, and eventual PCM (powertrain control module/main engine computer) failure. Coils and PCM melt or fail simultaneously.
When: 96,000+ miles; one owner at 84,000 miles
Symptoms owners cite: Engine misfire (audible cylinder misfire); Rough, shaking driving with poor acceleration; A/C stops blowing cold air; Check engine light; High transmission revving before shift; Transmission running rough
Codes mentioned: P0352 (Ignition Coil 2 or PCM fault), Multiple misfire codes on ignition coils
Repairs/costs cited: Spark plug replacement and individual coil replacement did not resolve issue. Complete repair required replacement of PCM (main computer), all 6 ignition coils, and spark plugs. Total repair cost $3,000. One case charged $800 for initial 'possible cause' that wasn't correct, then additional $1,700 after PCM failure.
PTU (Power Transfer Unit) leak
PTU develops grease-like fluid leak underneath vehicle. Ford Edge known for this problem. Replacement cost high and does not address other drivetrain issues.
When: After extended ownership; one example at vehicle purchased new in January 2009, leak noticed January 2016
Symptoms owners cite: Grease-like substance leaking under vehicle
Repairs/costs cited: Mechanic stated PTU replacement cost ranges from $1,700 to $2,400. This vehicle also exhibited transmission slamming and acceleration lag issues.

What owners are reporting 2 most recent
My husband was driving with me and our 2 children on the highway at 70 MPH. All gauges (fuel, speedometer, odometer, etc.) stopped working and the odometer read "odo data error". We had a GPS that we were using and displayed our speed, so we kept going the 5 miles to our planned stop along the way home. When we restarted the car, the gauges were back up but it made a loud thumping sound when…
