Kept my vehicle all day and charged $175 diagnostic fee to tell me what I already knew and told the service tech when scheduling the appointment . I already knew the compressor was shot but wanted to know why which I assumed it was a leaking air bag which he told me he could not determine until they replaced the compressor. ($4200 quote) I was able to determine it myself after getting on YouTube and using a spray bottle of soap. I also asked for a quote on an air ride delete which the tech quoted me replacing the rear bags. I asked about the front and he said there are no front air bags. There are.. you can see them with the tires still on. I’m not even sure they looked my vehicle over and just charged me for the obvious. I normally don’t leave reviews but for $175 (diagnostic fee) I would expect a more thorough inspection. Would not go back
