About 20 minutes into my commute home, my Jeep Wrangler (2018) started to squeal when I accelerated. Then, the rpm’s dropped and the Jeep stopped moving. I sat on the side of the road for a bit, started back up and it drove again, not over 30 and not for long. The rpms dropped and I had to start the process over to make it home. I’m told this is a common Jeep problem and it’s a small part. Any idea what this is?
