NHTSA Complaint #11519776 — 2012 CHEVROLET TAHOE

While barely moving, (about 2 mph), in a parking lot & preparing to make a sharp left turn, knuckle of driver's side wheel assembly suddenly broke, causing the wheel assembly to collapse, wheel top tilted inward and bottom tilted outward, causing major damage to upper and lower control arms, tie rod and significant body damage to two body parts at the wheel opening. Mechanic reported that there had been very excessive ‘play’ before the collapse At 86,000 miles, this is a very low-mileage for this degree of wear and complete failure, on a full-size, PPV SUV, with many heavy-duty features, designed to tolerate high stress usage. FORTUATELY, the car was barely rolling. If this had happened 5 minutes later, I would have been driving 65 mph and this would have caused a catastrophic wreck, could have involved several other cars, and could have injured or even killed many people. I am now very concerned about the condition of the knuckle on the passenger side. It could be developing microscopic cracks that would only be observable with X-ray. ESPECIALLY with this defect being on a very popular police model, Highway Patrol PPV vehicle, more failures will endanger many people.
