I have had my Cascada in for service on the same issue three times. It starts very rough and then I get messages - something about Stabil... not working and the engine light is on. The last time the engine light kept blinking - never good. Each time they tried like heck to find the problem, and each time they thought they did. This last time they brought it a tech specialist, told me they had to replace the entire electrical harness, but ended up with this..."found harness rubbing fuel line clip. I had multiple codes each time this problem happened. My car was in the shop about 10 days total. Got it back yesterday and so far so good, but if it happens again we will have serious discussions. Our dealer is fantastic and they have worked tirelessly to find this issue.
