The 2022 Escalade ESV 6.2L engine is failing catastrophically across a wide range of mileage, from under 10,000 to over 50,000 miles. Owners report sudden, total engine seizure while driving at highway speeds—often 70+ mph—with zero warning lights beforehand. The engine stops dead, shifts involuntarily into neutral, and in many cases cannot be manually shifted out of Drive, complicating towing and leaving occupants stranded in active traffic. One owner's family sat on a mountainside cliff for hours waiting for specialized towing. Another's wife and three children were nearly struck by passing traffic.
Before complete seizure, some owners notice metallic knocking sounds, hesitation on acceleration followed by surging, oil pressure warnings, or excessive oil consumption. Diagnostic findings cite damaged crankshafts, connecting rods, pistons, and bearing failures.
GM issued Recall 25V274000 in 2025 for connecting rod and crankshaft defects, but owners report dealerships are backlogged for months, unable to schedule appointments, and unable to source replacement engines. One owner's vehicle sat in the shop for 35 days; another waited seven weeks. Even after recall work, owners report symptoms persist—abnormal oil consumption, hesitation, whining, and vehicle dynamics issues—yet dealers deny problems exist. One owner's complete engine replacement came back with no warranty.
Failure modes owners describe
Complete Engine Seizure / Total Loss of Power
Engine suddenly seizes mid-drive with no warning, forcing the vehicle into neutral and stopping completely on roadways. Multiple owners report this occurring at highway speeds (70+ mph) with zero prior warning lights. In some cases, the vehicle cannot be shifted into neutral manually, complicating towing and creating roadside hazards. Owners cite damaged crankshafts, pistons, connecting rods, and bearing failures upon inspection.
When: Ranges from 9,635 miles to 50,000+ miles. Two owners report engine seized twice (once at 9,875 miles and again at 43,050 miles; another at 71k miles then again later).
Symptoms owners cite: Sudden loss of all engine power while driving; Vehicle lurches or hesitates before stalling; No warning lights or check engine messages prior to failure (in many cases); Vehicle shifts into neutral involuntarily; Cannot restart after stalling; Vehicle locked in Drive; cannot shift into Neutral; Loud banging, knocking, or grinding sounds before failure in some cases
Codes mentioned: Crankshaft damage (seized), Connecting rod failure, Bearing failure, Piston rod damage (cylinders 1 & 5 noted in one case), Lifter failure (right side noted in one case at 71k miles)
Repairs/costs cited: Engine overhaul, removal and reinstall reported in one case; most require complete engine replacement. Parts backordered nationally through GM with no estimated arrival times (some owners report waits of 5–7 weeks, one owner 35 days). One owner quoted $13,000 for replacement; another mentions $155k vehicle with no resolution. One replacement engine came back with no warranty.
Recalls/TSBs owners mention: GM Recall 25V274000 / N252494003 (connecting rod/crankshaft defect in 6.2L L87 engine). One owner reports recall inspection passed despite ongoing engine issues. Dealers citing backorder status and inability to schedule repairs. One dealer failed to schedule five recall requests over six weeks.
Engine Knocking / Pre-Failure Noise
Mechanical engineer owner described a distinct, frequency-dependent knocking sound indicating internal bearing or valve train wear. Owners distinguish this from normal operation; one wife did not recognize it as abnormal. Knocking correlates with poor lubrication or worn internal components and precedes catastrophic failure in at least one case (owner had knocking sound, took vehicle in, dealer immediately retained vehicle and ordered complete engine).
When: One case documented around 47,000 miles; another case at very low mileage prior to subsequent seizure.
Symptoms owners cite: Distinct knocking sound that changes frequency with engine speed; Noise audible outside vehicle or with windows down; Sound varies with engine temperature; Metallic ticking or knocking at warm idle
Codes mentioned: Main bearing wear, Lifter or cam follower wear, Pre-emptive internal engine damage
Repairs/costs cited: One owner's vehicle held at dealer after knocking diagnosis; complete engine replacement ordered (under 47k miles). No specific repair cost cited.
Recalls/TSBs owners mention: GM aware of bulletins sent to dealers per owner research. Recall 25V274000 addresses internal defects.
Abnormal Oil Consumption / Low Oil Pressure
Owners report oil consumption between scheduled changes, requiring frequent top-ups, and in at least one post-recall case, oil level dropped so low it did not register on the dipstick. One owner reports screen message 'oil pressure low' before engine died. First complaint suggests 0W-20 synthetic oil does not adequately protect engine internals at higher mileage, and technician recommended switching to 5W-30.
When: Noted before and after recall service. One case occurs post-recall work. Another case cited before complete engine seizure.
Symptoms owners cite: Need to add oil between scheduled services; Oil level extremely low or unreadable on dipstick; Screen message: 'oil pressure low'; Excessive oil consumption without obvious external leak
Codes mentioned: Low oil pressure
Repairs/costs cited: One shop recommended switching from 0W-20 to 5W-30 synthetic to improve protection of engine internals. Post-recall oil consumption prompted safety concerns but no dealer action reported.
Recalls/TSBs owners mention: GM recommends 0W-20 synthetic per owner; dealer technician counter-recommended 5W-30 as better for engine wear protection. Recall work did not resolve or prevent abnormal oil consumption in at least one case.
Hesitation / Surging / Throttle Response Delay
Owners describe delayed acceleration response when pressing the gas pedal, followed by sudden surge or jerking motion. Some note RPM erratic fluctuations with engine surging up and down. Post-recall, one owner reports vehicle hesitation and erratic behavior after 'completed' recall repair.
When: Ongoing or post-recall (one case at 44,000 miles after recall completed; another ongoing).
Symptoms owners cite: Delay in acceleration response after pressing pedal; Vehicle surges suddenly after hesitation; Erratic RPM fluctuations; Engine surges up and down while driving; Hesitation on startup or when shifting into Drive
Codes mentioned: Misfire codes (implied)
Repairs/costs cited: Post-recall case: dealer found no performance issues and did not repair despite owner report. No repair costs cited.
Recalls/TSBs owners mention: Recall 25V274000 completed in August 2025 in one case, yet symptoms persisted; dealer performed no repair. Manufacturer not informed per complaint.
Engine Misfires / Rumbling Noise on Deceleration
Owners report rumbling noise from engine when releasing the accelerator pedal and frequent engine misfires increasing stall risk.
When: Ongoing; one case post-recall inspection.
Symptoms owners cite: Rumbling noise when releasing accelerator; Frequent engine misfires; Increased stall risk
Codes mentioned: Misfire fault (implied)
Repairs/costs cited: None reported.
Recalls/TSBs owners mention: Symptoms reported to NHTSA; owner believes inspection should not have passed despite symptoms.
Steering and Brake System Issues (Post-Engine Work)
After recall or engine work, one owner reports vehicle pulling to left or right with no warning light, requiring steering compensation. Another post-seizure case initially diagnosed with driver's side rear brake harness needing replacement (at 9,635 miles), though context unclear whether this is root cause or coincidental.
When: Post-recall at 44,000 miles; early failure at 9,635 miles.
Symptoms owners cite: Vehicle pulls left or right during normal driving; No warning light illuminated; Requires steering wheel compensation to maintain lane
Repairs/costs cited: Brake harness replacement noted at 9,635 miles; post-recall pulling not repaired (dealer found no performance issues).
Recalls/TSBs owners mention: Post-recall vehicle not repaired; manufacturer not informed per complaint.
Whining Noise / Abnormal Sounds Post-Recall
One owner reports abnormal whining sound after recall service was performed.
When: Post-recall at 44,000 miles.
Symptoms owners cite: Abnormal whining sound; No warning light illuminated
Repairs/costs cited: Vehicle not repaired; dealer found no performance issues.
Recalls/TSBs owners mention: Manufacturer not informed; recall marked completed despite ongoing symptoms.
