I just took my Jeep in for service and I reported a hissing sound that I could hear when the GC was at idle and the climate control system was on. The service department said that it was normal and that it was a relief valve. Does anyone else get this kind of sound with the climate control on?
I also had another issue (whistling at idle) that they have been unable to resolve even after three visits...seems like it either does not happen when I drop it off or they are ignoring it and just saying it is normal. I am not a tech (nor did I sleep at a Holiday Inn Express last night), but I know enough about engine sounds to know the whistling is not a normal engine sound. I complained and the service manager said "well you bought the vehicle at another dealer why don't you take it there"...so it's time to find another dealer or drive 20 miles out of my way to the place where I bought the Jeep.
This is the one time I hope I get one of those survey e-mails...
