NHTSA Complaint #11494221 — 2017 GMC YUKON XL

Not sure if this is the correct raea to notify regarding this incident. I had windshield replaced by Safelite Auto Glass in Cadillc Mi.After the service the technician said he calibrated everything and all is fine. Upon my initial driving after the windshield service the vehicle engine light was flashing and the display was telling me the advanced collision and lane departure warning systems were inoperable. Additionally the vehicle would not accelerate. The vehicle could not be driven safely. I contacted Safelite in Cadillac Michigan the next morning and was initially told the warnings have nothing to do with the service they performed and they do not have to do anything to help me. The manager advised that they ran 3 scans with their equipment and all scans came out good. The manager is saying that confirms everything was OK. I see that as an admission of something being wrong since the technician ran 3 scans. Why run additional scans if all is good. What he was seeing is that the vehicle was displaying warning lights and was not running properly. That is why he kept running scans over and over. Even after 7 scans now they are still saying it's not their problem. Obviously their equipment is incapable of calibrating the new windshield to the vehicle. Additionally they have caused a problem within the engine control module by hooking up faulty electronic device. The vehicle is inoperable. Additionally Safelite knows that they are incapable of performing windshield replacement on this vehicle. The technician no more than left my driveway and I received a text from Safelite saying: "Modifications to your vehicle may cause your advanced safety systems to not function a intended" That is admission thjat Safelite knows they are incompetent in this matter. The windshield is in of the most important safety feature in a vehicle. It is unacceptable the an industry leading automotive aftermarket company is continuing to operate this way. Please look into this.
