Took my SSR into the dealer on August 9 for overheating and roof not retracting. Just got it back yesterday September 16. They replaced the thermostat and replaced rubber plastic roller to a plastic design. Roof worked fine yesterday, see how long it lasts. It took GM 6 weeks to tell them to change the rollers. Now I have to take it back because my hood is out of alignment. don't know what they did to cause this. They fix one thing and something else happens. My SSR has been at the dealers more than I have driven it.
