2021 Cadillac Escalade Esv

The Super Cruise hands-free driving system disengages frequently, citing lane marking visibility issues, GPS signal problems, or driver attention warnings even when the driver is looking at the road. On some highway sections that should be mapped for Super Cruise, the system reports the road is not available. The large windshield of the ESV can cause glare interference with the driver attention camera.

Update the Super Cruise map data through OnStar or the MyCadillac app. Clean the windshield around the forward camera and ensure the driver attention camera on the steering column is clean. Dealer performs Super Cruise module software updates. Reference GM TSB 22-NA-089 for Super Cruise camera calibration procedures.

The air ride adaptive suspension system experiences compressor failures and ride height sensor malfunctions. The compressor runs excessively trying to maintain ride height, leading to premature burnout. Ride height sensors can provide incorrect readings, causing the vehicle to sit unevenly or display 'Service Suspension' warnings. The ESV's longer wheelbase puts additional demand on the air suspension system.

Replace the air suspension compressor if it has burned out. Inspect all air springs, lines, and fittings for leaks using soapy water. Replace faulty ride height sensors. Ensure the air dryer assembly is functioning to prevent moisture from entering the system. Reference GM TSB 21-NA-167 for air suspension diagnosis on the T1XX platform.

The 6.2L L87 V8 with Dynamic Fuel Management (DFM) is prone to the same lifter collapse issue affecting all T1XX platform GM trucks and SUVs. A lifter collapses and causes a ticking noise, misfire, and check engine light. On the Escalade ESV, this is particularly frustrating given the vehicle's premium price point, and owners expect better reliability from the flagship engine.

Dealer replaces the failed lifters, VLOM, and potentially the camshaft under powertrain warranty. Reference GM TSB 15-06-01-002F for diagnosis. Some owners elect to install a DFM/AFM delete kit to eliminate the cylinder deactivation system and prevent recurrence, though this may affect warranty coverage and emissions compliance.

The 38-inch curved OLED display cluster that spans the dashboard can develop dead pixels, burn-in from static images (such as the gauge cluster outline), and intermittent black sections. Some owners report the display flickering or showing color banding. As one of the first automotive applications of OLED technology, the display is expensive to replace.

Dealer diagnoses the display module and performs software updates. If dead pixels, burn-in, or flickering are present, the display module must be replaced. The display is covered under the new vehicle warranty. GM has released software updates to include screen savers and brightness management to reduce OLED burn-in risk.

The power-retractable running boards fail to deploy, retract, or become stuck in the extended or retracted position. The electric motors and hinge mechanisms are exposed to road debris, salt, mud, and water, causing corrosion and motor burnout. When stuck in the extended position, the running boards can scrape on steep driveways, speed bumps, and curbs.

Lubricate the running board hinge pivots and motor linkage with a silicone-based lubricant. If the motor has failed, replace the running board motor assembly. In severe cases with hinge corrosion, the entire running board assembly may need replacement. Regular cleaning and lubrication of the hinges every 6 months can prevent failures.
