By now most people have heard of the General Motor’s 6.2L recall Titled “L87 Engine Loss of Propulsion”, but there is still more information to come. Currently, there is a stop sale on the 6.2L effected by the recall, meaning that dealers are not supposed to sell them until the issue has been corrected. However, as of 5/6/2025, there is not a remedy available yet so that make the situation a little more difficult to navigate.
What vehicles are affected? 2021 – 2024 Cadillac Escalade & Escalade EV; 2021 – 2024 Chevrolet Silverado 1500, Tahoe, & Suburban; 2021 – 2024 GMC Sierra 1500, Yukon, & Yukon XL all fall under the recall.
What do we know so far? Repairs are VIN specific, meaning not all 6.2L’s will receive the same repair, depending on when they were built. Some will be very simple corrections (an oil change and a new oil requirement going forward) and others will have very complicated and lengthy repairs (an engine replacement). There will be three bulletins and three separate procedures to ensure that the “Loss of Propulsion” issue is corrected. The equipment to test some of these engines are still being shipped to dealers as of 5/6/2025.
What parts are affected? The connecting Rod and/or crankshaft engine components in the effected vehicles may have manufacturing defects that can lead to engine damage and engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion.
What are the signs that this may happen to your vehicle? In our shop we have experienced customers having issues starting their vehicle even though the battery is fully charged. We believe that this is due to the damage on the thrust bearing and/or crankshaft creating a “tightness” in the internal engine components making the vehicle difficult to start. Also, a misaligned crankshaft may set off a P0016 code. There may be other signs out there, but these are the ones we know to exist.
If you have already had an engine replacement, will you need another one? Unfortunately, if you have had an engine replacement you may need another one if your engine was replaced was with a unit that was manufactured before the 2024 cut-off date.
Hope this helps, you can contact your local service department for additional information or updates.
