NHTSA Complaint #11511685 — 2013 CHEVROLET EQUINOX

At about 115,000 miles my carefully maintained one-owner vehicle began to occasionally shudder, and then finally stalled on a couple of occassions. I found out later (after the check-engine light was activated, apparently due to a failing catalytic converter) that the shuddering, and the ruined catalytic converter, were both due to excessive oil consumption--the result of a piston ring defect that I learned about years after a class-action settlement that I was never notified about. The dealer charged me $230 to diagnose these problems. My safety was at risk because of the engine stalling (this happened while driving on two separate occasions), and also because of exhaust/oil fumes seeping into the interior of the vehicle when switching the A/C to defrost mode. Failed catalytic converter and excessive oil consumption was confirmed by the dealer but GM/Chevrolet and dealership refuse to provide remedy. (See https://www.classaction.org/blog/new-class-action-claims-more-chevy-equinox-gmc-terrain-vehicles-plagued-by-oil-consumption-issue) (See also https://www.classaction.org/blog/lawsuit-says-2013-equinox-terrain-drivers-not-given-proper-notice-of-oil-consumption-deal-due-to-gm-mistake) Neither the dealership nor General Motors notified me of the settlement or Special Coverage Adjustments that would have required them to cover the repair costs, and although I have contacted GM Customer Care several times and spoken to various case managers, they have refused to acknowledge their failure to notify me about the problem, much less cover the needed repair costs. It is worth noting that GM notified me about previous recalls, they never informed me about the costly, dangerous problem that I now have to deal with on my own. The problem eventually resulted in a ruined front catalytic converter. The dealership estimates that repairs would cost more than $8000 (more than the vehicle's market value). Please help--I NEVER RECIEVED ANY NOTIFICATION FROM GM ABOUT DEFECTS!
