SERVICE BRAKES, ENGINE
The Vacuum pump continues to go out causes code P1101. I have replaced it 4 times and people just in my town are fighting this code for dear life like me! It causes our brakes to barely work and make it completely unsafe to drive as the check engine light goes in and out for MAF sensor. It’s not safe. It needs to be recalled. It doesn’t matter if i buy the most cheapest part or expensive part. It has happened on multiple occasions where i replace it and within 2 months, its back on and does reduced power in the middle of me driving on busy roads. i’ve been almost hit and almost caused multiple accidents because I have to pull over.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM
After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once the brake had become harder to push and stop the car. OBD scans show DTC codes that were pertaining to MAF and MAP malfunctions in readouts and communications to the ECM. After further inspection, the ABS module had been acting as "backup" for hydrolic brakes system that had zero vacuum to power the brake booster, this could have caused the engine to stall, longer than normal stopping distances (stronger risk of rear ending other drivers), and multiple components and sensors to fail, requiring them to also be replaced.

The backup camera for this vehicle is starting to fail and the view is blurry. Additionally, it seems that this also is affecting the rear traffic alert as I almost crashed into someone at a parking lot when trying to back out of a space. I will soon have no rear camera or cross traffic alerts.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
Every so often I get an indication of engine power reduced, but every time I go in to get it checked it's off. I have recently just learned through research online that the issue is caused by a certain condition that gives false reading to the electronics. I have contacted GM and GM financial about the recalls on my cars of the same year. I have not been in a wreck but I have had the issue of engine reduced power in the middle of traffic. Cox Chevrolet in Bradenton has turn me away about the issue GM financial is giving me the runaround neither one mention anything about a recall instead I get a estimate $400 /$808.50/1900.41 all to fix ECM as I told the mechanic I was driving with no problem through the day me and the kids at the park when it was time to leave the car sounded like it just didn't have no gas. We was stuck tell 10:45 we waited two hours for the tow truck. I have OnStar and get monthly reports on my car. When the check engine light comes on OnStar has no indication that's why I believe it is the same ECM. I was told by Chevrolet Maher service manager of St Pete to get my car off their lot as I said before I got a estimate of 400 that went up to 800 and all I did was ask why
