NHTSA Complaint #11559253 — 2020 CHEVROLET SILVERADO 2500

I purchased this vehicle brand new from Lunghamer Chevrolet in Pontiac, MI. I park my truck on a hill every day and as of around a week ago the emergency brake system won't disengage properly. I know it has been engaging since, my gas milage has decreased significantly. Then, a warning light came on the dash, so I took it to Wally Edgar Chevrolet in Lake Orion for diagnosis and they told me that the actuators and wiring harness need to be replaced. They said that there seems to be corrosion on the connector to the harness, and the actuators need to be replaced. Since, my warranty is expired they will not cover the repairs and they quoted me $2,125. I only have 48,428 miles on this vehicle! If the emergency brake is engaged, couldn't it completely stop my vehicle without warning? I drive the highway every day! Isn't this a safety concern? I don't go off road, I don't abuse this truck and I keep it clean as much as possible! Yes, I live in Michigan but, GM has been producing vehicles for quite a long time and I cannot believe they can't keep the wiring connector from corroding. I also went online to see if there were others that have experienced this, and I found one owner of the same model that had to fix it twice! [XXX] . I'm sure I could find more complaints but, I stopped there since I am so disappointed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
