DO NOT BY ANY MEANS trust this service department with your vehicle. This is by far the WORST service department I have EVER dealt with in over 20 years. I have had numerous unsatisfactory service appointments with them on my 2013 Silverado 2500HD 6.6L Duramax.
10 December 2016 - Took vehicle for service appointment due to check engine light being on. OnStar remote diagnostics indicated a problem with the emissions system. It SAT AT THE SERVICE DEPARTMENT for several days before it EVEN GOT LOOKED AT. Service advisor at AutoNation South (Victor Landa) informed me that it was likely due to having an aftermarket Banks air intake on the vehicle. I keep OEM parts in case the aftermarket cause issues. I asked if I could put the OEM part back on by myself to save a bit on labor costs, and was told no. $389 later, and 40 miles of the techs driving my truck to "make sure the problem was resolved," I get my vehicle back. Oh - and the vehicle was in for a total of 10 days. As I noted earlier, it didn't even get LOOKED AT for the first 3 or 4 days. I wasn't even OFFERED a loaner vehicle. I had to ask for one, and couldn't get one until about day 4.
24 January 2017 - Less than a month later, the check engine light is back on. OnStar remote diagnostics again indicates an emissions issue. I take it back in and see Victor again. This time, it's the DEF fluid heater. This one was covered by warranty. It required the removal and reinstallation of the DEF tank. A bit fishy that a month after the first service visit, a second service visit for an emissions issue is necessary. Fortunately this one was covered by warranty. As for a loaner vehicle, I was able to get one the same day, but only because someone brought one back early.
27 June 2017 - check engine light on again. OnStar remote diagnostics indicates an emissions issue yet again. AutoNation South couldn't get me in to see a diesel tech for over a week, because I refused to drop of the vehicle until it would actually be looked at or they could provide a loaner vehicle. Autonation North took the vehicle the same day, but as per usual with Autonation, no loaner vehicle was available. The problem this time was the indirect fuel injector. This was covered by special warranty from a recall. However, I was informed by the service tech (Dennis) that it also required a catalytic regeneration. I was charged $238 for the catalytic regeneration that was ONLY necessary because the indirect injector was faulty. I was informed that it was not covered by warranty because a catalytic regeneration is a routine service/maintenance issue. To this day, that does not make sense to me. If the faulty injector caused a dirty engine burn, requiring the catalytic regeneration to be performed to clear the diagnostic trouble code, shouldn't that be covered? But I digress.
7 October 2017 - routine maintenance. Vehicle was in for diesel oil service, vehicle inspection, and tire rotation. Service manager was Jason Wilson. When I returned to pick up the vehicle, the driver's information system stated "Service Tire Pressure Monitor System." I informed Jason, and he said that it would reset within a few miles of driving because of the oversized tires. OK - I've never had that happen before, but against my better judgement, I drove it home (about 7 miles). It didn't reset by the time I got home, so I looked online for info and found several mechanic forums indicating that on 2012 and newer models, a reset tool should be used to reset the TPMS sensors after a rotation. Back I go to the service department. I arrived about 3 minutes after closing, and found Jason as he was closing up. He looked at it for less than five minutes, brought it back to me, and said that neither of their TPMS reset tools could find the sensors. I have taken my vehicle to AutoNation south for 4 oil changes and tire rotations in the 2 years I have lived here, and this is the FIRST time I have had this problem.
While this is long, I do hope it helps to illustrate the general incompetence, unethical business practices, and poor customer service that is FREQUENTLY encountered with this business. I would sooner drive my vehicle to San Antonio than go here again. It is a pity that AutoNation has a virtual monopoly on GM Service Departments in Corpus Christi. There is no incentive for them to improve their quality of service, because anyone who wants GM "Certified" service would have to drive over an hour to find another option. read more
