NHTSA Complaint #11707761 — 2021 KIA TELLURIDE

I purchased the 2021 Telluride (former owner of a Sportage, Rio and Sorento). I have our local mechanic handle maintenance and service. After paying $1,400 for a tune up to address misfiring, we quickly concluded the transmission was shot and my engine was burning theough every drop of oil before it was due for a change. I went to Kia of Des Moines, since it is covered under a 200k/20-year warranty. They replaced the transmission under warranty, I shared my mechanic details for records, and they told me they were going to do an oil consumption test. They sent me on my way, asking for me to return after 1,000 miles. I did (and then my car began shaking, but we thought it was due to snow conditions) and they quickly said, "Yes, it is an issue!" My Telluride burned through almost 2.5 quarts of oil in 1,000 miles. I left on 12/15, being told they would have direction from Kia corporate on next steps and acknowledged I need a vehicle loaner during repairs (single disabled mother, who has to travel safely). I did not hear back, chasing for updates. Yesterday, Steven text me saying I would need to authorize $1,600 engine tear down fee in order to confirm issue. I asked for Denny, the manager to contact me. I also called Kia Care, who said it is up to dealer. I am seeing so many issues with Tellurides burning oil. And, I do not have $1,600 to make my vehicle safe - that amount would make me sacrifice my home or another necessity. Google said to fight it and to submit a form to you also. I have to fight this because I have no other choice than to sell an organ. I will stock up on oil to keep filling it so my engine doesn't blow up, but have incredible fear of being stranded and not being able to get my vehicle towed or us home safely. If there is anything you can assist with, I appreciate it. I just found out my parent's 2023 telluride is burning too much oil too - they haven't got the $1,600 sticker, but I know that amount will wreck them also.
