Intake camshaft actuator solenoid valve. I had the oil consumption services completed last October 2017 and this year in October 2018 I had to have the camshaft actuator solenoid valve replaced to which everyone I know with an Equinox that is older than 2016 is having to have this part replaced on their vehicle. I feel that with such a drastic amount of vehicles having this fixed if it wasnt apart of the oil consumption parts to have replaced it should have been because it really appears to be a largely replaced item costing people over $200 to have fixed. This part causes your vehicle when at lower speeds to stall out over and over until it just wont go. It started with a rough idle. Then when accelerating at low speeds the vehicle would stall out. Finally it would stall while I was driving at low speeds.
Purchased vehicle used with 64000 miles Aug 24th, 2015. After about 2 weeks the car stalled while backing out of a parking spot. Re-started it and it stalled again. Happened again in late sept, once in oct and again in Nov. Dealer replaced faulty intake solenoid 11-13-15. Leaving for work on Jan 19th and noticed oil leak (no low oil light). Drove straight to dealership. 1/4 mile out my engine light comes on saying reduced engine power, drops me to 30 mph. Get to dealership and it's a blown rear seal. Replaced loose timing and balance shaft chain, water pump, coolant flush ( I paid for) abs light came on, so sensor was found to be "open" also found chunk of magnet missing from wheel bearing. Car in shop for 9 days. Picked up on 1-28-16. Stalled again 4 x on 2-4-16. Returned to dealership to have camshaft actuator replaced. Stalled again 2-7-16 and 2-8-16. Returned to dealership on 2-8-16. No word from them yet. The car has left me in the middle of an intersection turning left twice!! I could be killed by driving this vehicle. I have researched online and have found 1000's of people dealing with this same issue. Several have had the vehicle stall while traveling 70 mph on the freeway!! the issues exists on 2010, 2011 and 2012 models. Gm needs to take responsibility for the issue that no one seems to know how to fix. Does someone have to die before gm will deal with this issue?? these vehicles are also known for burning excessive amounts of oil. When I took it in for an oil change, they noted it was a quart low. Still no low oil light ever came on. One article I read said the issue is caused by a coating that was sprayed inside the camshaft during production is now leaking into the fuel/oil causing metal fragments and dirt to be in the oil.
