NHTSA Complaint #11632220 — 2015 CHEVROLET EQUINOX

Rear crankshaft seal has failed. Engin oil has blown out at bottom of engine and all over underside of car. Oil has covered the exhaust system causing smoke in and outside of car. Leaked engine oil could have ignited and caused a fire that would have consumed the entire car. There appears to be numerous postings on the internet of other chevy equinox owners with the same problem. There was no prior warning that the crankshaft oil seal was in the process of failure. I personally checked the oil pan drain plug and the oil filter cap, and these were not the issue of the oil leak. Again, from my investigation on the internet sites, it appears to be a common issue with the General Motors 2.4 Liter Vortec engine in the Chevrolet equinox car model. This issue can and probably result in total engine failure and need of engine replacement. The repair to replace the rear crankshaft oil seal is very costly and should not be needed on any vehicle with normal wear and use. With my internet investigation there appears to be a design problem with the PCV design and system. The PCV system is prone to clogging and freeze up in cold weather. This can result in excessive internal engine pressure the is a major cause of blowout of the crack shaft oil seal. The temperature at the night before was only 9 degrees. The car was last used under freezing conditions which could have contributed to engine failure.
