As I was coming to a stop at light my brakes became very difficult to push the pedal down to stop. It took everything in me to get the vehicle to stop before entering the intersection and oncoming traffic. I was able to get the vehicle parked safely in a nearby parking lot but then the engine wouldn't start it just kept trying to turn over. The brake assist error popped up, and then the check engine light came on. I was able to get it started again about 20 minutes later, all the same warnings and lights. I white knuckled the drive back to my house... Once I got home the engine was smoking, smelled like it was burning, and oil was spilling out all over the place underneath, impossible to see where a leak was as it was coming from the entire engine. There was ZERO warning with the vehicle, no issues up to this point, and suddenly the equinox is now useless in my driveway unable to start with oil still leaking in multiple spots. An oil pan under the main leaking area, but there are still multiple areas of oil spilling even a week later. Oddly enough my onstar report for the month came to email a few days later reporting perfect engine health and zero issues - even thought the vehicle can't start now.

While driving, the vehicle experienced an almost total loss of braking capability. The pedal was very hard to press, and when pressing with all my weight, I could slow the vehicle to a stop, but it took a great distance. There was no warning or malfunction indicator until I pulled into a parking lot a few minutes later. At that point, a "Service Brake Assist" message appeared. Had I been in traffic, going faster, or in an area with pedestrian crossings, this could have caused a possibly deadly crash. I searched online and found that there is a vacuum pump that is known to fail on this vehicle, and can cause these symptoms. Upon replacing this vacuum pump, the issue was resolved. I still have the failed vacuum pump.

One morning, in an attempt to start my car, it would not start. Instead, it lit up the check engine light. The engine was turning over and attempting to start, but would not start. I know someone with a code reader device that I asked to come hook up to my car and read what code was causing my check engine light to pop up. The reader displayed the code U18A2 which indicates a "Lost Communication with Fuel Pump Control Module (FPCM)". This commonly causes a no-start or stalling condition due to a broken CAN bus wire, corroded harness, or faulty FPCM ground. Key fixes involve repairing wiring along the frame rail. Many versions of the 2020 equinox have already been recalled for a fuel pump control module problem, and I was trying to inquire whether or not my vehicle qualifies as part of the recall for the fuel pump module.

I bought the equinox with 30,000 miles on it. It's at 67,000 now and I maintain the vehicle regularly. So why have I replaced the throttle body already because it gets dirty fast? And now I'm getting a check engine light for P2099 TurboCharger Underboost. When the vehicle is not old it's 5 years old, hasn't been driven hard. So why are you using a crap 1.5L engine with a turbo that is notorious for these issues??? And what's worse the engineering is horse s$*t, because the air inlet hose is only one time use. But the part is underneath it where you can't reach. Why has this not been recalled yet????????? It's not but a scam to make you take it to a dealership. I'll continue to write complaints this is not right. And I'll never buy one again.
