Automatic Cruise Control Sporadically Works

[Billw8]

My automatic cruise control doesn't always work. When it doesn't work, restarting the motor doesn't help. After a little time goes by it will then decide to work. When it is not working I have the cruise control button set and then I push the "set" button nothing happens. If I hit the "set" button repeatedly I will get an error message saying that the conditions are not met. I thought the front car sensors might be dirty, but taking it through the car wash does not help. The car has been doing this for over a year and I am hesitant to take it to the shop because they may not be able to duplicate the problem or they will say that road debris damaged the sensor and it is not covered under my extended warranty. My extended warranty expires in a few months and I am considering taking it to the shop. Have any of y'all had similar problems?

Why did you pay for an extended warranty that you are afraid to use? There may be fault codes stored from the times it wouldn't work.

Does the warranty cover diagnostics? A scan may reveal codes and it is a complex system. Use the warranty you are paying for.
