NHTSA Complaint #11552021 — 2018 JEEP WRANGLER

On several occasions, within the past year to year and a half, and when periodically driving my 2018 Jeep Wrangler across any sort of rough patch on the road, I would experience a severe and sudden shaking of the steering wheel along with very strong vibrations coming from the entire front end of the vehicle.......unfortunately however, I do not have any confirmation of such from any independent repair facility, nor has any independent inspection taken place, and without any warning ever from any interior "idiot" light, lamp, and/or the like. The recall notice I received earlier this year indicated that this phenomenon was the result of a failing steering damper. I subsequently submitted a purchase receipt along with a proof of payment for a new damper which I then self-installed. Now the "customer care" people @cac.stellantis.com won't reimburse me for the part because I did not have an independent repair facility install this very simple part to replace. Never did I receive any notification, nor was any information ever made privy to me, that independent installation was an absolute requirement for part reimbursement. Can you please help me reason with these people? Thank you.
