I was informed through a trade publication that Roadmaster had issued a recall of the towbar due to potential failure of a "roll pin" seated into a "stinger" assembly that could cause the towbar to separate and fail. I contacted Roadmaster on XXX, and recieved a response on XXX with vague and incomplete information relating to whether I could continue to use the towbar, although they described the matter as "urgent". The notice is at their webpage at [XXX] . I have inquired as to the proper method to inspect my towbar to determine if can continue to be used, but have recieved no reponse in over 3 weeks. The stated remedy is to provide a replacement for portions of the towbar to affected owners, but there is no indication that labor for replacing the parts in included. removing the large bolts required to replace the part is beyond the ability of most owners, and requires tools that most owners would not have. Presumably, there are torqueing or other installation requirements that would also be beyond the ability of most owners. Roadmaster's response to their published recall has been lacking in many regards, and should be addressed more openly and with better solutions provided for affected owners.

Adhesive inside the dashboard display is failing. It started at approximately 20,000 miles and has suddenly gotten much worse 1 year later at approximately 30,000 miles. This failure is causing "bubbles" in the display, which is interfering with the clarity/readability of the gauges, including the speedometer, which I consider to be a safety issue. Ultimately, I'm concerned that the screen may fail completely while I'm driving.

The laminated glass instrument/gauge cover has separated making it very difficult to see gauges for air, temp and speed.
