NHTSA Complaint #11521336 — 2014 HYUNDAI SONATA

My car has been at the dealer since 5/3 which i had an appointment for the TXXI engine failure and fuel pump 227 recalls. I was driving my lights all came on and the car decelerated and wouldn't speed up anymore the steering wheel also got tight.i just got oil change at the end of March and haven't been any long distances. I was told 2 days later that my car was being diagnosed it is now 5/10 and I'm still being told my car is being diagnosed with absolutely no update, they also refuse to give me a rental car or provide a out of house rental... They are making me pay out of pocket for rentals then can only post for reimbursement which isn't guaranteed after the work is done but cannot give me any type of word on even when the diagnostic will be done. I asked if they have any order to diagnosing like is it in order he said no i said so someone can bring their car in after mine and get completed before for same thing just depending on which the technician decides to do the advisor said yes candidly. I've been calling for updates and have not received anything other than the diagnosis is still not done after 7 days. I'm paying for a car that i don't have access to and it's not being expedited in order. When i dropped the car off they said it would take 4 days tops with are they starting my car then not finishing.
