I took my car to a second dealer on Monday (22 Nov) and they called me Wednesday (24 Nov) and said the battery capacity tested below the warranty level and will need to be replaced. They have placed the order for the parts and all the costs will be covered by the warranty. They won't know the availability of the parts till Monday (29 Nov) when the suppliers open after the holiday.
I still need to get the kWh result from the dealer so I can see how close my calculations were to the official measurements.
Also, there could be parts shortages that delay the repair but at least the process is started.
Recap of events (some dates are estimates*):
- 30 July - Took the car to Findlay Chevrolet. They told me that there was not a test for battery capacity/degradation and that they couldn't help me.
- 30 July - Called GM corporate to get warranty clarification. How can my battery capacity be warrantied if there is no test for capacity?
- 3 Aug* - GM called back and said they contacted Fairway Chevrolet and that dealer would be able to perform the required tests.
- 16 Aug - Dropped the car off at Fairway Chevrolet for testing and told them I wanted the High voltage battery capacity and degradation tested (it's on the work order recipe).
- 18 Aug - Picked up car from Fairway Chevrolet and paid $190. They said the test showed "Battery is within GM specs." I asked for the kWh measurement when I picked it up but was told I would need to get those numbers from GM HQ because the scanner sends the logs to GM and the technician did not have them.
- 19 Aug* - Called GM and they did not know what I was talking about and that they could not give me the kWh info cause they did not have it.
- 20 Aug* - Realized I had the whole service on dashcam. Fairway Chevrolet only had my car in the shop for about 30 minutes and the technician only spend 5-10 min looking at my car and the rest of the time they talked with other technicians.
- 23 Aug - Received this message from GM: "...as you have the diagnoses from the dealership that the battery is within specs that no repair will be made and the battery will not be replaced at this time." I messaged back that I did not believe Fairway Chevrolet performed the correct tests and I had done my own measurements that showed the battery was 40% degraded, and that I needed GM to provide kWh measurement to confirm or disprove my results before I would be satisfied.
- Got busy with work
- 20 Sept - Emailed Fairway Chevrolet about my dissatisfaction with the service.
- 22 Sept – Emailed Fairway Chevrolet again requesting a response to my complaint.
- 23 Sept – Received a message back from Fairway with this statement: ”As per GM repair procedure if no codes are set, there is no further action to be taken.”
- 23 Sept – Forwarded the message from Fairway to GM. I emphasized that the warranty does not require “codes to be set” for a capacity/degradation claim.
- 1,6,11,14 Oct – Phone calls with GM. My case was “escalated” so I needed to catch the new person up and we discussed what to do next.
- 21 Oct – GM told me that Findlay Chevrolet could perform the correct test.
- 28 Oct – Messaged Findlay Chevrolet through their website to confirm they could perform the test and schedule service
- 5 Nov – Had not received a response from my first request. Called Findlay Chevrolet and left a message with one of their service people with my info and questions.
- 8 Nov – Still no response from Findlay Chevrolet. So I called again and this time told them I would hold till they could answer my question. They confirmed they could perform the Capacity/Degradation test so I scheduled my service for Monday 22 Nov
- 22 Nov – Dropped the car off at Findlay Chevrolet
- 24 Nov – received a call from Findlay Chevrolet that the battery failed the test and would be replaced under warranty.
I don't know why Findlay Chevrolet told me they could not test the capacity/degradation the first time I asked, lack of EV knowledge and experience is my guess. However, Fairway Chevrolet was a total "Stealership" in my opinion. My coworker also took his Volt to them and he had a similarly bad experience.
