On Thursday [XXX] I purchased a 2021 Kia Sportage LX from Liberty Auto Plaza Dealership located in Libertyville, IL. During this purchase, the salesman Isaac told me the car was updated with Anti-Theft Protection. Between Friday [XXX] evening and Saturday [XXX] my Kia Sportage that I just purchased was stolen. I called the police department and made a police report and I filed a claim with my insurance company, American Alliance Casualties. My vehicle was recovered on Wednesday [XXX] and the insurance company picked the vehicle up on Friday [XXX]. My insurance company, American Alliance Casualties has had my vehicle since. [XXX] will be five months this company has had my vehicle. On [XXX] American Alliance sent me an Offer Letter to, either have the vehicle to be repaired or, have a direct check sent to me. I choose to have the vehicle repaired because I wasn't looking for money I wanted my car repaired. The company I chose was Fender Mender Auto Collision Center. I spoke with their receptionist, Heather on, Thursday [XXX] and she said my insurance company, American Alliance Casualties delivered my vehicle to their facility and they were going to start working on it right away. I called Monday [XXX] to follow up and see how is the progress going to repair my vehicle and she told me that there was something going on with the engine. On Monday [XXX] Heather from Fender Mender Auto Collision called and said my claim was denied because there is wear and tear on the engine. The engine has 27,000 miles from the time it was stolen so that's impossible. However, I spoke with the insurance adjuster Annette Khatib and she said the inspector stated there was a blockage in the engine possibly due to a manufacturer defect.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Kia Sportage Phev Phev verdict →
