Example complaints

Brakes: “I have experienced brake drag for a third time on my motor home and am filing a third complaint. Travel was on level roads in urban area traffic (low speed stop and go) when the front brakes began to drag. I found a safe place to pull off the road surface and had to wait hours for the brakes to cool down. I was able to proceed home by being very cautious with applying brakes and avoiding any congested areas. …”

Equipment: “For the third straight year I have had to take it my 2003 Winnebago Adventurer to an authorized workhorse service center because the dashboard air conditioning wasn't cooling. Each time the refrigerant was gone, they said no leaks could be found and they just recharged the system. They said the o rings might be drying up over winter and then the refrigerant is lost. I have contacted general motors because much of the air conditioning is mounted on their engine. They told me in a phone conversation that workhorse has to rectify the problem. I then e-mailed workhorse with my problem. …”
