The 2006 Escalade ESV with the 6.0L Vortec is a comfortable hauler with serious AFM (Active Fuel Management) engine problems and transmission cooling issues that can turn expensive fast. Great platform when maintained, but these two issues define ownership.
AFM Lifter Failure & Camshaft Wear
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Ticking or tapping noise on cold start that may disappear when warm, Check engine light with P0300-P0308 misfire codes, Rough idle or cylinder deactivation, Metal shavings in oil
Fix: AFM system collapses lifters, wipes camshaft lobes. Requires cam replacement, all 16 lifters, valve springs, oil pump, timing chain. Best practice is AFM delete with tuning. 18-24 labor hours for proper job.
Estimated cost: $3,500-6,000
Transmission Oil Cooler Line Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission fluid leaking at radiator connections, Pink or red fluid under vehicle, Transmission slipping or delayed engagement, Milky transmission fluid if cooler ruptures internally
Fix: Rubber cooler lines rot from inside out, can contaminate radiator coolant or vice-versa. Replace both lines, flush system thoroughly. If coolant mixed with ATF, transmission rebuild usually required. Lines alone: 2-3 hours. With trans rebuild: 12-16 hours.
Symptoms: Burning 1+ quart of oil every 500-1000 miles, Blue smoke on startup or acceleration, Carbon buildup on spark plugs, Loss of power under load
Fix: AFM-related carbon deposits cause ring land cracking or ring seizure. Requires engine rebuild or replacement. Can do top-end with pistons/rings (16-20 hours) or go with used/reman long block (12-18 hours).
Estimated cost: $4,500-7,500
Transmission Mount Deterioration
Common · medium severity
Typical onset: 70,000-130,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive vibration at idle in gear, Visible sagging or cracking of mount rubber, Driveline shudder on acceleration
Fix: Rubber mount splits from engine torque and weight. Replacement straightforward but requires supporting transmission. 1.5-2.5 hours depending on access.
Estimated cost: $250-450
Steering Shaft Intermediate Bearing Clunk
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking from steering column when turning at low speed, Clicking noise when going over bumps with wheel turned, No loss of steering control
Fix: Intermediate shaft U-joint or bearing wears out. GM updated parts available. Replace intermediate shaft assembly. 1.5-2 hours.
Estimated cost: $300-500
Fuel Pump Failure
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Hard starting, especially when hot, Stalling or loss of power at highway speed, Whining noise from fuel tank, Won't start, no fuel pressure
Fix: In-tank pump fails, common on GM trucks this era. Tank must be dropped. Replace entire pump module with AC Delco unit. 2-3 hours.
Estimated cost: $600-900
Rear HVAC Blower Motor Resistor Failure
Common · low severity
Symptoms: Rear AC/heat only works on high speed, No rear blower function at all, Intermittent rear climate control
Disable AFM with a Range/AFM disabler device or tuning at first sign of lifter noise — prevention costs $400, repair costs $5,000
Inspect transmission cooler lines every oil change; replace proactively at 80k miles if original
Use quality full-synthetic 5W-30 oil and change every 5,000 miles maximum — AFM system is oil-quality sensitive
Budget $1,000/year beyond normal maintenance if buying over 100k miles — these eat camshafts and transmissions
Buy only if AFM has been deleted or you have $5k set aside for engine work — otherwise a comfortable tow rig with a ticking time bomb under the hood.

CERTAIN TRUCKS AND SPORT UTILITY VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES WERE SHIPPED WITH TIRE AND LOADING INFORMATION LABELS LISTING AN INACCCURATE VEHICLE CAPACITY WEIGHT.
Consequence: A MISPRINTED LABEL COULD LEAD TO IMPROPER VEHICLE LOADING SPECIFICATIONS OR TIRE INFLATION WHICH COULD RESULT IN A TIRE FAILURE, INCREASING THE RISK OF A CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH CORRECTED LABELS AND INSTALLATION INSTRUCTIONS. AT THE CUSTOMER'S OPTION, A DEALER CAN INSTALL THE LABEL FOR THEM. THE RECALL BEGAN ON MARCH 31, 2006. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, HUMMER AT 1-800-732-5493, PONTIAC AT 1-800-620-7668, SATURN AT 1-800-972-8876, OR ISUZU AT 1-800-255-6727.
STEERING:HYDRAULIC POWER ASSIST:HOSE, PIPING, AND CONNECTIONS · 05V455000
2005-10-05
CERTAIN PASSENGER VEHICLES MAY HAVE BEEN BUILT WITH A POWER STEERING HOSE THAT IS NOT TO SPECIFICATION. UNDER EXTREME STEERING MANEUVERS, SUCH AS TURNING THE STEERING WHEEL FULLY TO THE LEFT OR RIGHT WHILE BRAKING, THE HOSE MAY FRACTURE AND LEAK FLUID.
Consequence: IF THIS WERE TO OCCUR, POWER STEERING ASSIST WOULD BE LOST AND INCREASED STEERING EFFORT WOULD BE REQUIRED. ON VEHICLES EQUIPPED WITH HYDRO-BOOST POWER BRAKES, IT COULD ALSO RESULT IN LOSS OF POWER BRAKE ASSIST AND INCREASED BRAKING EFFORT WOULD BE REQUIRED. IF THE POWER STEERING FLUID SPRAY WERE TO SPRAY ONTO HOT ENGINE PARTS, AN ENGINE COMPARTMENT FIRE COULD OCCUR.
Remedy: DEALERS WILL INSPECT THE POWER STEERING HOSE(S) FOR TWO SUSPECT DATE CODES AND REPLACE THEM IF REQUIRED. THE RECALL WILL BEGIN ON OCTOBER 14, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, ISUZU AT 1-800-255-6727, OR HUMMER AT 1-800-732-5493.
