Last summer (2023) the ABS light would come on when starting the vehicle and stay on until the vehicle warmed up and it would go off. By the fall it just stayed on. Stored my RV for the winter and took it to service dept. this April 2024. They conducted a computer scan and the ABS pump is defective. Similar to the first complaint I read about ABS systems on this site. Vehicle is a 2017 Chev. chassis converted to a Coachman Leprechaun RV in 2018. I am the original owner and vehicle has 30,000 miles on it.
