Based on consumer feedback, some 2022 Li Auto L9 Max units have reported common problems with the electric power steering system, such as heavy steering feel. When buying this used car from a trusted used car dealer, it is critical to thoroughly inspect the steering system for abnormal noises or resistance. Additionally, this specific used vehicle has no documented maintenance records, so the included free professional deep inspection (valued at $51.29) is highly recommended to assess the condition of the range extender, battery pack, and chassis components—key areas that impact long-term maintenance cost. As an EREV under the Chinese electric cars category, the 1.5T engine operates at low load primarily as a power generator, which typically reduces mechanical wear and contributes to better long-term reliability compared to traditional internal combustion engine used cars.
