Hyundai Sonata: Engine
Affects Hyundai Sonata · 2017 — about 309 vehicles.
The hazard
Issue: On certain vehicles, the software update that was installed during campaign R0180 (Transport Canada recall numbers 2021-034 or 2021-575) may not be effective. As a result, a second repair is required. Hyundai Auto Canada is conducting a Product Improvement Campaign that provides an update to the engine control module to detect potential problems before an engine fails. An engine failure would cause a sudden loss of power with an inability to restart. Note: This campaign only affects certain Sonata Hybrid (HEV) and Sonata Plug-in Hybrid (PHEV) models equipped with a 2.0 L Nu GDI engine. Safety Risk: A sudden loss of engine power could increase the risk of an accident. An engine failure could also create the risk of a fire. Corrective Actions: Hyundai will notify owners by mail and advise you to take your vehicle to a dealer to update the software for the engine control module. Note: Hyundai recommends that you should always follow the correct vehicle maintenance schedule, which is printed in the Owner's Manual. If you experience unusual engine noise, reduced power, or a check engine/oil warning light, Hyundai advises you to immediately visit a Hyundai dealership to have your vehicle diagnosed.
