I am writing the NHTSA to advise of a harrowing event involving the vehicle named above. I was driving my 2022 Yukon vehicle equipped with the 6.2L Ecotec3 V8 L87 Engine. As I was traveling, the vehicle suddenly without warning shut down. When this occurred all systems in the vehicle became completely inoperable; i.e., no power steering, no power brakes, nothing, Etc. I was lucky to be able to veer/coast into the Emergency Lane without incident. This situation also caused the vehicle to become almost un-towable, in that the towing company could not get the vehicle out of the Park position to allow the wheels to rotate. They had to use special Skid Plates / devices to essentially force the vehicle to Slide instead of rolling onto the towing vehicle. This added significate hazard and risk of injury because of the problematic situation of loading the vehicle in this manner literally inches from the active travel lanes and took much longer to load than it would have otherwise. The vehicle was towed to the local dealer. The Dealer replaced the Fuel Module and returned the vehicle. This information is being sent to GM as well. After this event I was concerned for driving the vehicle but now after reading about the recent NHTSA Investigation into Engine Failures I am much more apprehensive about driving the vehicle. Even if nothing happens individuals who have these vehicles have now lost significant value and face a very difficult time even being able to sell their vehicles at all, or at a much lower price than normal because of the known Defects. I hope this helps the NHTSA to further their Investigation of GMs defective vehicles and get these vehicles repaired and/or replaced in a timely manner before tragedy strikes any individuals.
