Engine & cooling

I received a customer satisfaction notification from FCA US LLC stating they were recommending some improvements on my 2017 Fiat 500X equipped with a 2.4L engine. They had determined that some vehicles may have been consuming more oil than usual. We had noticed our car running low on oil between oil changes so we took it to our local Fiat dealer with the letter and they stated it wasn't coming up in their system so they couldn't run the test for us. We contacted Fiat directly and they stated the same thing. We did...

My vehicle has abruptly shut off on my twice now. The first time, I had just made a turn from a busy intersection near my home when the vehicle came to a stop. Though the car stopped moving, none of the electrical functions of would shut off. I had to disconnect the battery to make it shut off. I had the car towed to the car dealership for service, and they returned the car to me, doing nothing because the issue didn't happen when they started the car a day later. Fast forward several weeks, the car stopped -- this...

time on the final space of a bridge. By the grace of god, we coasted to the bottom of the bridge where the car stopped completely. Again, the car wouldn't shut off, but it just didn't move. I had to disconnect the battery. This time, I left the car where it was, and I returned to pick up the car 24 hours later. The car started and ran just fine. I then had it towed to the dealership because I was feeling uncomfortable driving it. They have kept the car for four days, and they called me to say they didn't do anything because they can't figure out what's wrong with it. Because there's an outstanding recall (and, coincidentally, an ensuing class action lawsuit) on the car, they told me they would initiate the recall action. This is two part action -- I believe -- because fiat has no intentions of paying for these repairs. I do not know if this is what is wrong with my car, but the mechanic did indicate that the oil consumption issue manifests itself in the ways I have described. So I have to keep my car for 1,500 to 1,700 miles and then only return to the dealership if I believe it's the oil consumption issue. I'm not sure how I'm supposed to determine that. Additionally, because we're in a pandemic, and I wfh, it will take me ten+ months to accrue that many drive miles.

The car stopped working suddenly in the miami turnpike, drive mode not available went on, also abs, parking and engine lights went on. It was scary because stopped working without previous notice. We almost have an accident. It happens the same in 2015, same model in tampa highway.
