Ever since the lifters broke in the new vehicle (which the dealer now tells us is a defect in the engine and that the lifters keep breaking; it was not a "bad delivery of lifters" as we were initially told), the car idles very rough and has power surges. Today sitting at a red light with the foot lightly on the break, the car lunged forward against the break during one of the power surges. If…

Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
Powertrain accounts for 18% of all owner complaints filed against this vehicle, across 3 categories tracked.
No new NHTSA powertrain complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Multiple 2021 Cadillac Escalade ESV owners report severe powertrain failures including catastrophic engine damage, lifter defects, and transmission problems—some matching known recall patterns but excluded from coverage. Engine failures occurred as early as 25,000–45,000 miles, with GM denying warranty claims and dealers unable to diagnose transmission shifting issues.
The 2021 Escalade ESV powertrain complaints cluster around five distinct failure types. Most serious is catastrophic engine damage—rod and piston bearing collapse that destroys the block. Two owners reported this exact failure at 77,632 and 45,997 miles respectively, both claiming their vehicles match a known 6.2L recall pattern yet were excluded from coverage. Both owners describe the same warning signs: loud knocking, sputtering, multiple warning lights, then engine seizure.
Lifter valve failure is the second major issue. Multiple owners report lifters breaking prematurely, causing rough idle, power surges, and unintended acceleration at traffic lights—one owner's vehicle lurched forward with enough force to create a collision hazard. Dealers acknowledge this as a known defect, yet lifters reportedly fail repeatedly even after replacement.
Sudden loss of engine power strikes without warning at highway speeds. One owner experienced complete power loss at 25,000 miles; another at 30,000 miles. Vehicles cannot restart and require towing. One dealer found an internal case defect; others have not diagnosed the root cause.
Transmission shifting autonomously is documented in one complaint where the vehicle shifted itself, made grinding noises, and shot forward uncontrollably—resulting in a collision. The owner had reported the issue twice to the dealership prior; service could not locate the problem.
One additional complaint reports engine stalling at traffic lights with no known remedy. No warnings precede these failures.

Failure modes owners describe
Rod and piston bearing failure
Catastrophic internal engine failure with bearing collapse on connecting rod and piston, destroying the engine block. Owners report this matches a known 6.2L recall pattern but some vehicles are excluded from the recall despite identical symptoms.
When: 77,632 miles; 45,997 miles
Symptoms owners cite: Loud knocking sound from front of engine; Engine sputtering; Multiple warning lights and messages; Loud noise and shaking; Clunking sounds; Vehicle unable to continue operating
Repairs/costs cited: Complete engine replacement required. Dealership confirmed rod and piston bearing failure.
Recalls/TSBs owners mention: Recall available for some 6.2L engines (campaign number not specified in these narratives), but some owners with identical failures report exclusion from recall. GM initially agreed to cover one owner's replacement engine, rental car, and shipping at no cost, then reversed decision citing powertrain warranty expiration (7,000 miles over limit).
Lifter valve failure
Valve lifters fail prematurely, causing severe engine degradation. Dealer states this is a known defect. Owners report rough idle and power surges persist even after lifter replacement.
When: Early in vehicle life; no specific mileage provided for lifter failures
Symptoms owners cite: Rough idle; Power surges while driving; Vehicle lurching forward unexpectedly at traffic lights; Complete engine failure requiring replacement
Repairs/costs cited: Lifter valve replacement performed; however, lifters reportedly breaking repeatedly. One owner required complete engine replacement.
Recalls/TSBs owners mention: Dealership acknowledges lifter failure as a known engine defect but no recall or manufacturer response documented in these narratives.
Sudden loss of engine power
Engine loses power without warning while vehicle is in motion, forcing immediate deceleration and stalling. Vehicles cannot be restarted and require towing.
When: 25,000 miles; 30,000 miles; high mileage during highway driving
Symptoms owners cite: Sudden complete loss of engine power; Vehicle deceleration without driver input; Engine stalling; Unable to restart vehicle; No warning lights or advance notice reported in some cases
Repairs/costs cited: One owner reported internal case defect found by dealer; replacement case ordered. Most cases still under diagnosis.
Recalls/TSBs owners mention: No manufacturer response documented for loss-of-power failures. One owner suspects fuel pump failure based on internet reports of recalls on some 2021 Escalades for fuel pump, but his vehicle has no such recall.
Transmission shifting on its own
Transmission shifts gears autonomously without driver input, creating unsafe vehicle behavior including unwanted acceleration and grinding noises. Service visits unable to diagnose the issue.
When: Multiple occurrences; one critical incident occurred at car wash approximately 2/11/24
Symptoms owners cite: Vehicle shifts gears on its own; Dragging sensation during shifting; Weird noise when attempting to shift manually; Grinding pulling noise; Unintended forward acceleration (vehicle shot forward like catapulted); Excessive RPM behavior inconsistent with actual speed; Downshifting while pressing accelerator pedal
Repairs/costs cited: Service advisor twice unable to locate problem. No repair performed.
Recalls/TSBs owners mention: No manufacturer response documented. Dealer unable to resolve issue despite multiple service attempts.
Engine stalling at traffic lights
Engine stalls while vehicle is stopped at traffic lights or stop signs with no apparent cause.
When: Unspecified mileage
Symptoms owners cite: Engine stalls while stopped at traffic light; Engine stalls while at stop sign; Stalling occurs twice in same vehicle
Recalls/TSBs owners mention: Owner reports no recalls listed for his vehicle despite stalling incidents.
