Some Isuzu Ascender owners report experiencing issues such as check engine lights, slow movement, and multiple fault codes like P2764 and P0787, which are often linked to transmission problems. Additionally, owners have noted non-functional wipers, which may indicate a malfunctioning wiper motor or electrical system, as well as a faulty fuel gauge caused by issues with the fuel level sensor, leading to erratic readings.
