HOW DO I KNOW IF MY GM HAS THE PCV SYSTEM FREEZE DEFECT?

According to the firm’s research, the PCV system freeze defect can lead to a range of consequences for vehicle owners, from a seal replacement that may cost over a thousand dollars, to complete engine failure costing several thousands of dollars. Many vehicle owners complain of no warning before the seal fails, leaving them stranded in freezing temperatures and putting them at risk for injury or death.

WHAT GM OWNERS ARE SAYING ABOUT THE DEFECT

Owners of affected GM vehicles have taken to online forums and NHTSA (the National Highway Transit Safety Administration) to report complaints pertaining to this dangerous defect:

  • “2016 GMC Terrain just blew a rear main seal. Weather is cold 20-30 degrees. 76,000 miles….help!”
  • “…those good folks might be dangerously stranded on the side of a road.... they might be late for work, or late for school, and those good folks with be screwed with a more than $2000 bill to fix their GM SUV…”
  • “Recently on a below zero night, roughly 70 miles from home, my Equinox completely stalled on the highway - stabilitrac warning, low engine power warning, tried to make it to the nearest town in limp mode and the engine shut down in the middle of nowhere. Found out I had a main seal failure caused by the PCV valve failure…”
  • “While driving, the warnings ‘oil pressure low stop engine’ and ‘engine power low stop engine’ suddenly appeared. I turned the vehicle off immediately and had it towed to a mechanic who found that the PCV orifice was clogged and built up pressure in the engine blowing out the rear main seal and drained the engine of all its oil.
  • “I was driving down the highway and I heard a knocking and, before I could do anything, my display said I had low oil pressure and to turn the engine off. The engine cut off just as I got to the shoulder of the road. Needless to say, there was oil everywhere on the engine and the engine was seized. My car is toast.

GENERAL MOTORS PCV SYSTEM DEFECT EXPLAINED

According to the firm’s research, the defect occurs in cold weather when the vehicle’s PCV system freezes, causing pressure to build up in the vehicle’s crankcase that breaks or pops out the rear main engine seal. This can drain all oil from the vehicle and even cause total engine failure. 

WHAT DID GM KNOW?

According to research, GM has known since at least 1985 of the PCV system’s vulnerability to cold weather and clogging, as it has repeatedly advised dealers (but not customers) on how to attempt to address the problem. Despite this track record, GM continues to conceal this defect from consumers at the point of sale, and continues to design, manufacture, distribute and sell hundreds of thousands of vehicles prone to this defect.

HOW CAN A CLASS ACTION HELP?

The class-action lawsuit seeks repayment for vehicle owners and lessees for related losses, including loss of vehicle value due to the defect. Class members may have other claims to repayment as well under the law. The lawsuit also seeks to create a fund paid for by GM to compensate those affected for out-of-pocket costs incurred when trying to fix the effects of the PCV freezing defect.
