2017 Sedona · 32,000 miles · Jan 2019

I am writing to file a formal complaint regarding a serious issue my vehicle has been unusable since July due to a defective AC control head. I initially took my vehicle to an authorized dealership, and they informed me that the part required is on national back order. After an extensive search, they located the part at a dealership in California, but the order was canceled. I was then told that many replacement control heads are being returned as defective, leaving me without a functioning vehicle. The dealership has indicated that the back order could take anywhere from one week to three years, which is an unacceptable and indefinite delay. I am currently unable to use my vehicle because temperatures in the Phoenix metro area average between 105+ degrees during this time of year. …
