Stability Control and start/stop issues
We just bought a used 2018 limited with 15k miles. My wife drove it from NY to GA from the dealer. The start/stop light and stability control lights stayed on.
We took it to the local dealer. There were 1.5 pages of codes. They said there was a recall on a grounding issue and they needed to replace a vacuum pump on the stability control. That’s on order.
So after driving it 3 miles, the start/stop light came back on. From my research, that seems to be a weak battery for that system. It did sit for 5 months at a dealer.
When the new part comes in, do I man up and tell them it’s the start/stop battery? As in just replace it?
Has anybody else had the vacuum pump issue with the stability control and if so, did the replacement fix it? The car seems too new to have parts replaced this soon.
