Drivers treat AI as a triage + how-to co-pilot—snap a photo or pull an OBD-II code, ask ChatGPT/Grok for the likely culprit, part number, and step-by-step fix, then either DIY or walk into the shop with a clear brief. In 2025, early “talk-to-the-engine” agents report ~95% diagnostic accuracy across ~40 cars—great for fast triage—while users still double-check with codes/manuals before turning a wrench.

Using ChatGPT and an ODB2 diagnosis tool to understand wtf is going on with my car 😅
My check engine light came on and AC stopped working. ChatGPT told me to go to Autozone and get the code read. It diagnosed the code. Had me replace a blown fuse. Boom… fixed! My wheels are spinning… if you own an auto shop… https://t.co/fFQqE23jcb
This dude took a chance and bought a worn-down truck, hoping to turn it into a home He used ChatGPT to fix it up, saving 10k in the process https://t.co/fEQ8gRb1kU
My truck broke down and with Grok I saved almost a thousand by not going to a mechanic. I used Grok to diagnose all the symptoms and issues and with a bit of trial & error I was able to figure out the broken part. Grok even gave me instructions on how to replace it. Amazing.
I just used @grok to locate a data port fuse on a 2018 LCF4500, and it was 100% accurate. 10a blown fuse replaced, and now the scan tool is reading. It's not the first time I've used it to diagnose a problem vehicle. Seriously, this is sort of a game-changer.
This entire thread is pretty incredible. TJ using Grok and a little FreightX hive-mind to fix his truck. You love to see it. https://t.co/YPGWlOzyr9
I took my car to the dealer for an AC problem which chatGPT has diagnosed. I showed them what chatGPT said was wrong. He seemed shocked it knew things. Now we wait to find out if it’s right.
Last night my daughter’s car battery died, it was old, so I replaced it. When we got home I noticed the radiator fan didn’t shut off. (Hence the battery issue) Used ChatGPT to diagnose and find a replacement relay. Normally, I’d take it to the shop. DIY IS SO BACK!! https://t.co/gSY7SY8UAd
