I restarted it and it sounded different, so I drove it home. The next morning it would not start. The failure occurred at approximately 69,939 miles with no meaningful warning.  The dealer\u2019s diagnostic report states there were no current relevant codes and no relevant codes in history. The dealer documented major timing-system failure: timing chain tensioner failure, timing chain guide failure, a timing chain guide bolt pulled out of the cylinder head, aluminum contamination in the cylinder head/oiling system, and engine replacement recommended. The vehicle was found unsafe to operate.  This vehicle regularly transported my family, including my children. If the stall/no-start failure had occurred at highway speed, while merging, or in heavier traffic, it could have created a serious crash risk.  The oil was maintained outside the dealership network and had been serviced before failure. I also topped off the oil shortly before this occurred. The 2.4L Ecotec engine family is known for oil-consumption issues, yet this vehicle gave me no direct warning that oil consumption had reached a dangerous level. A reasonable owner would not know to check oil every day when there were no relevant stored warning codes.  Other NHTSA complaints involving 2016 GMC Terrain vehicles describe similar patterns: oil consumption, no warning lights, sudden stalling or no-start conditions, timing-chain failure, and engine replacement recommendations.  I am filing because this appears to be an ongoing safety risk involving oil consumption without adequate warning, timing-chain/timing-guide failure, internal contamination, and sudden engine failure. I request NHTSA review this issue for investigation or recall expansion before this failure mode causes a preventable serious crash, injury, or fatality. The vehicle was inspected by a GMC dealer and remains unrepaired.","products":[{"type":"Vehicle","productYear":"2016","productMake":"GMC","productModel":"TERRAIN","manufacturer":"General Motors, LLC"}]}]}
