Almost four years, after acquiring our first Chevy Volt, I finally had a service issue with my 2017 Volt, “The Silver Surfer”. The problem was that the A/C stopped running in automatic mode (i.e. thermostatically controlled), but ran perfectly, in manual mode. Classic Chevrolet‘s service team determined that the A/C controller unit was faulty and needed to be replaced. It took a couple days to get a new controller. Once installed, there was software that needed to be installed, to initialize the controller. Once that was completed, the controller failed. This happened twice. The GM Volt Support Team had our Service Tech checking wires for shorts, but none were found.
My Volt had been in the shop for three weeks and I got it back today. I’ve had a Volt loaner (LT model) as a replacement for my Premier, because Classic added Volts to their loaner fleet, knowing Volt owners don’t want to drive an ICE when their Volt is being serviced.
The Service Technician (Pat Galan) was tenacious, in tracing the problem. On two occasions, he was advised by GM’s Support Team to keep checking the wiring for short circuits. Pat felt there was something else going on, because he could get the controller installed and everything would check out. But once he installed the software, things would stop working, or worse, the controller would fail.
Then something odd happened: A Volt in Washington state had the same issue. Then four more in the Eastern U.S. exhibited similar problems. Pat became more and more certain that there was something wrong with the software or the installation program. GM’s Support Team contacted Pat and verified what he’d surmised: The software installer program was faulty. A new install app was sent out and everything worked!
Many, many thanks to Tim Foote, my Volt Service Advisor, who kept me updated, during this process, Pat Galan, the Service Technician who was tenacious in his efforts to track down the culprit and Mike Zorn, the Service Manager who kept checking on things to keep everything on track, even though he was unaware that the Volt was mine.
This proved what I’ve thought for years now: Your selection of a salesperson, knowledgeable about your new vehicle (especially the Volt) is important, but just as important is your selection of a Service Department that truly understands your vehicle and a dealership that supports the vehicle by making sure the technicians are well-trained, certified and have the freedom to delve as deeply as is warranted to get to the bottom of any issue.
Pat’s a smart guy.
How many car mechanics would suspect a software defect?
There’s a lot more to working on cars now than there was a decade ago or two ago.
Agreed, on both comments.
