The P0556 code gets stored when the PCM has detected a problem with the brake booster pressure sensor circuit because of abnormal feedback. Braking distance significantly affected by brake pedal becoming difficult to depress. Cause is the brake booster vacuum pump. Internet reports indicate multiple vehicle types during the late 20-teens and early 2020s. Problems are occurring during or shortly after warranty expiration. This is a very dangerous problem that could cause serious injury.

Vehicle had 3 warning go off while driving. Vehicle engine is shaking. It decelerate and I couldn’t go over 35. No power going up hill. Traction controls shut off, check engine, and SEC service came on. Now messages of braking system and emission from on star. Had a similar incident over thanksgiving and I was told I needed an oil change because there was low oil. My car was at 58% for oil change. Now I’m at 83% and it shouldn’t need oil. There have been multiple issues with lag time from pushing the gas to engaging. This vehicle has had more issue than any other Chevy I have owned. Transmission seals off the lot. This is not building confidence in safety at all.

The contact owns a 2020 Chevrolet Equinox. The contact stated while driving into her driveway, the vehicle lost motive power with the check engine warning light illuminated.

The approximate failure mileage was 27,500.

I was driving out in the country on 1-41 towards West Union. The steering tightened up and came up with a sensor that said Power steering ESC. The car went offroad due to the steering tightening from the power steering going out in the vehicle. I contacted the dealer, Mike Castrucci Chevrolet, and they told me that I would have to pay for any problems with this vehicle and I have only had the vehicle for 3 weeks. I put $2000 down on this vehicle and now am in a deathtrap due to this issue. The vehicle only has 60,800 miles and feel now that this issue could put my life and others at risk due to a faulty steering issue. I do not understand why this vehicle has driven beautifully to this point and yet there are many Chev Malibus that have that problem. How long will it take before someone recognizes this problem. There were no warnings before and I could have gotten myself and my friend killed in this car driving at night in the country. I spoke with an AutoZone representative and he said that he had a Chev Malibu with the same issue. They discovered that it was the power steering motor having to do with the traction control. I guess that I will be forced to keep driving this vehicle, and if there is an accident, then I should hold liability to be General Motors and Mike Castrucci Chevrolet who refuse to fix this car. When I took the vehicle, I was promised that they would stand by their car. I am getting no help with this situation. However, this is my only vehicle so I will keep this on the road until this is resolved. If you should wish to contact me, my number is [XXX].
