2017 Fiat 500X

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 receive a letter so I don't understand what the issue is. My daughter drives the car and now I feel it's a safety issue for her. I wrote a letter to the FCA and have not yet received a response. I need help with this issue and running out of resources to help.

What component or system failed or malfunctioned, and is it available for inspection upon request? - The component that failed is the RFHM module in the rear driver side wheel well of the car. Due to water leaking into the car, the RFHM module is taking on water damage causing several electrical systems to fail including power steering, airbags, and starter. Both current RFHM and previously damaged RFHM module are available I believe. How was your safety or the safety of others put at risk? - As the car takes on water, the module fills internally with water as well. When this happens, several components of the car begin to go haywire including security, power steering, airbags, and other electronic readers. When this happens going down the road, my car has and can potentially shut itself off which is very dangerous going down a highway. Has the problem been reproduced or confirmed by a dealer or independent service center? - I first diagnosed what was going on through with my car through other online forums of people experiencing the same problems. I took my vehicle to my mechanic where he ordered a new RFHM Module and had a mobile locksmith acquire a new key. The locksmith was able to program one old key and one new key with the new module and the car was good to go again. Now, six months later, the same issue is happening with the same piece of equipment. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - I have not pursued this yet but will be in touch with the manufacturer tomorrow. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There is no way to know when the car will work or when it won't after it rains or after a car wash. The symptoms come on suddenly and take time to dry out to be useable again.

My Fiat 500 x only has 28k miles on it, and it is a manual transmission. While driving, it will not shift into the upper gears. I was told that it needs a new transmission. This seems to be the same issue that the same make and model Fiats from 2016 have been recalled for. Mine is a 2017, but it has the same issue and should be recalled, as well.
