Chevy is the problem not the electronics. Seriously GM sedan and coupes in the last 10 years are some of the worse designed, engineered and assembled automobiles since the 2000-2004 Chrysler Sebring. GM primary problem is isolated to the vehicles with the pcm mounted on the battery those modules fail all the time.

That said the battery itself is just a normal flooded battery and the auxiliary battery is a little pricey just because it’s not a common battery size.

Best thing you can do short of doing it yourself is always get a 2nd opinion on repairs. I had a lady yesterday come to me for a second opinion and I confirmed what the first shop told her was corrrect. I then got to offer my services a discount to earn her business, my normal prices where’s about the same as the first shop. But guess what it’s December and I want the job today so I gave her a discount to earn the work.

Use competition to shop price on everything, otherwise your paying full price which might be a fair price but it’s not the best price you can pay.
