Owners of some 2021 through 2024 diesel-powered Cadillac Escalade and Cadillac Escalade ESV units registered in California may experience a no-start issue under certain conditions. The problem has been identified and a Service Update has been released to prevent the issue from occurring in the future.
Service Update No. N242441450 states that affected units of the Cadillac Escalade featuring the turbodiesel 3.0L I6 engine (production code LM2) may fail to start after the Auto Stop feature has been activated. This feature switches the engine off while at a full stop, such as while in traffic or at a stoplight, to improve fuel economy.
In order to fix the problem, the affected Escalade must be brought into a dealership service center, where the engine control module (ECM) will be updated. This service is expected to take 24 minutes to complete and will be performed at no cost to Cadillac Escalade owners. Note that because this is a Service Update, rather than a recall, it will expire at the end of the New Vehicle Limited Warranty period. Additionally, the fix must be completed as soon as possible on Escalade units that are currently in dealer inventory, as affected models must not be sold, delivered, demonstrated, or traded until it has been performed.
Cadillac did not disclose how many Escalade units have been affected by this issue, but as previously mentioned, it only includes vehicles registered in California.
As a reminder, the diesel-powered Escalade produces 277 horsepower and 460 pound-feet of torque. That engine bolts to the luxury marque’s 10-speed automatic transmission. However, it’s worth noting that the refreshed 2025 Cadillac Escalade will not offer a diesel option whatsoever, something Cadillac Society was first to report. In fact, the last diesel-powered Escalade will roll off the assembly line on September 16th, 2024.
Production of the Cadillac Escalade, which rides on the luxury marque’s T1 platform, is handled at the Cadillac Arlington plant in Texas.
