On the 2021-2024 Cadillac Escalade L87, the T1XX Escalade's 6.2L L87 V8 has a documented connecting-rod bearing failure that is separate from the older AFM lifter problem and separate from oil consumption. Manufacturing debris left in the crankshaft oil passages and rod-bearing dimensional variation on engines built in a specific window let the bearings wear through the overlay and into the copper, which then knocks and can seize the engine outright. The failure is often abrupt: owners report a knock, an oil pressure warning, or a complete no-start seizure with very little warning and sometimes under 30,000 miles. The complaint concentration is striking - CarComplaints shows 34 of the 61 total complaints on the 2023 Escalade filed under engine problems, and the 2021 Escalade carries engine as its largest NHTSA complaint category with multiple open defect investigations and recalls. GM has addressed affected VINs through a field action that both inspects/replaces engines and, for engines passing inspection, changes the required oil viscosity and shortens the service interval.

This issue also affects: Buick Encore, Buick Envision, Cadillac CT5

Common Symptoms

  • Deep knocking or rod knock from the lower engine that changes with throttle
  • Low oil pressure warning or the check engine light before failure
  • Engine seizes and will not crank, sometimes with no prior noise
  • Metal flake or copper-colored debris on the oil filter or drain plug
  • Loss of power or a sudden stall while driving

How to Fix

First, run your VIN through the GM/Cadillac owner recall lookup and the NHTSA VIN recall tool - the remedy for an affected vehicle is dealer-performed and free, and it is the only path to a covered engine replacement. If the engine is symptomatic, stop driving it; continuing to run a knocking rod bearing turns a bearing job into a crankshaft and block replacement. Do not let a shop tell you a rod knock is a lifter - the two sound different and are diagnosed differently: a rod knock is a deep, load-dependent thump that changes with throttle and often quiets briefly on a cylinder-cut test, whereas an AFM lifter tick is a lighter top-end tap present at idle. Have the dealer perform the prescribed bearing inspection and pull an oil sample for analysis; copper and lead in the oil report is direct evidence. For engines that pass inspection, GM's remedy specifies a heavier oil viscosity and a shorter change interval than the original spec - follow it exactly, because the whole point is raising the oil film thickness at the bearing. Out of pocket, an L87 replacement is roughly $8,000-$12,000, which makes pursuing the field action the only sensible route.

Typical repair cost:$0 - $12,000

On the 2021-2024 Cadillac Escalade, gM 22-NA-182 and 22-NA-015 cover bounded 2021-2024 Escalade 10-speed concerns. A twisted cooler line or incorrect fluid level can contribute, while a 25-50 mph shudder can reflect DFM operation, engine torque variation, valve-body or TCC-solenoid behavior, or true converter slip. The symptom alone does not identify a failed torque converter.

This issue also affects: Cadillac Escalade ESV, Chevrolet Silverado 1500

Common Symptoms

  • Harsh transmission shift
  • Shudder between about 25 and 50 mph
  • Transmission flare or surge

How to Fix

Resolve DTCs first, reproduce the concern with GDS data, verify the exact engine and MHS, MHO or MQC transmission branch, inspect cooler-line routing and fluid level, and separate engine torque variation from converter slip before replacement. Do not use a universal reset, flush or converter prescription.
