There are many GMC Sierras and Chevrolet Suburbans and Tahoes and several Cadillac Escalades in circulation in the Dominican Republic.
Take note that the United States National Highway Traffic Safety Administration (NHTSA) issued a recall on 24 April 2025, for all General Motors vehicles with the L 87/6.2-liter engine, for model years 2021-2024. This recall (N252494001 and following) is for Cadillac, GMC and Chevrolet vehicles with this engine. The recall has been made in three phases: first, for dealers, then for owners within the warranty period, and lastly for all vehicle owners.
This issue is serious. The L87 6.2L engine has a major flaw. The crankshaft is not at the correct tolerance, and the rod bearings tend to disintegrate, and the engines destroy themselves, leaving drivers stranded or worse. To appreciate the seriousness of this recall, dealers were instructed not to sell any vehicle with this engine made during the 2021 to 2024 model years.
Specifically, issues with the connecting rods and crankshaft, including sediment contamination and dimensional/finish inconsistencies, have been identified as contributing factors.
Dealers cannot receive a used vehicle, nor can they sell a used vehicle with this engine. At first, GM said that owners should use 0w-40 oil, but the following day, the company rescinded this advice and told owners to stop using the vehicle. If the vehicle was under warranty, it would receive a new engine.
