Buick warranty extension N242450640
Buick filed this with NHTSA as a warranty extension dated Nov 6, 2024, about the engine. It names 1 model year (2021). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSpecial Coverage. Certain vehicles, equipped with a 1.2L engine, may have a condition that could cause the turbocharger to fail. If this condition occurs, the Malfunction Indicator Lamp (Check Engine Light) will illuminate, and a diagnostic trouble code will set. Additionally, a message may be displayed indicating the vehicle’s available engine power is reduced. Dealers are to replace the turbocharger as necessary. The repairs will be made at no charge to the customer.
