Cadillac Escalade
3.0L inline-6 diesel, aluminum block, single turbo — the only I6 diesel in the US luxury SUV segment. LM2 (2020-2022): crankshaft reluctor wheel fails, engine cranks without starting. Repair requires cab-off, 40+ labor hours. DEF system with frequent warning messages and limp-mode risk. Rear main seal leaks on early production. Highway 24-30 mpg, towing 12-15 mpg. Torquey long-distance cruiser with teething problems.
Diesel Escalade — long-haul not horsepower
277 hp sounds modest for a vehicle this size, but 460 lb-ft of torque makes the difference when towing and highway cruising. Fuel economy: 24-30 mpg highway. DEF system issues and the early no-start problem (2020-2022) cloud the picture. From 2023 significantly more reliable.

Vehicle Weaknesses 8
Rod bearings can fail at low mileage — linked to the L87 machining debris recall. Free engine replacement by dealer.
Air leveling system on the T1XX Escalade fails — Service Leveling System message in DIC. Complex sensor/actuator system with multiple failure points. Door ajar switches are wired into the leveling system.
Clear coat peels especially on front fenders and hood. Multiple NHTSA complaints documented. Dealer repaint often covered under goodwill.
Super Cruise driver assistance deactivates sporadically or is unavailable on mapped road sections. OTA software updates resolve most cases.
38-inch OLED display shows burn-in effects, flickering, or partial blackouts. Replaced under warranty, expensive out-of-warranty (>$2,000). Display dims significantly in direct sunlight.
Brembo six-piston front calipers handle daily driving well — but hauling 6,200 lbs through repeated hard stops or any track use heats the system quickly. Stock pads under spirited driving: 15,000-20,000 miles.
At $150,000+ base price, some plastic surfaces feel downmarket compared to Urus, GLE 63, or BMW X5 M Competition. Lower dashboard and door panel plastics particularly criticized.
EPA rated 11 city/17 highway mpg. Real-world mixed driving: 13-16 mpg. Highway at posted limits: 16-17 mpg. Filling a 24.2-gallon tank costs approximately $90-100 at current US fuel prices.
