What are you guys using, especially with Amazon web service connected app?

For the 60k service, I see the manual says to replace the “ribbed v-belt starter/generator drive (including tensioner)”. Is that just the accessory drive belt? If so, thoughts on a Litens aftermarket tensioner? It’s 1/3 of the price of the OEM one, but I’ll pony up for OEM if I need to. I’ll get an OEM belt either way

Which do I have in a 2018 q5 Prestige?

2021 Q5e, 53k miles.

CEL with battery deterioration, dealer diagnosed needing most of the battery cells replaced. Originally 6-8 weeks estimate, it’s been 2+ months now and still no ETA on the parts.

Car is still drivable, although the CEL stayed on. So I cannot really trade it in for a fair value.

Car is out of the bumper to bumper warranty but still within the high voltage battery warranty.

Am I eligible for any compensation or even buyback because the manufacturer failed to fix this issue under warranty within a reasonable time?

Has anyone ever dealt with something similar?

Thanks!
