When driving down a major highway going 70MPH, my 2017 Chevy Malibu speeds decreased, the brakes locked up, and the vehicle would not accelerate. Eventually the car came to a complete stop and an “engine power reduced” notification came up on the dash. I was able to pull off to the side of the road but I was traveling at a high rate of speed on a busy road, I almost got hit multiple times by people behind me who also had to swerve out of the way to keep from getting hit. After turning the car off and on again it seemed to run fine for a few months until the issue happened again going down a busy highway (65mph) again putting myself, my kids and others on the road behind me at risk. Now the car won’t move more than 5 feet before shutting off with “ engine power reduced “ still displaying on the screen.

Engine power reduced

On Thursday, [XXX] my [XXX] son was driving my chevy malibu coming down the hill to get home when the brakes went out. He could not stop the vehicle and had to pass our neighborhood and let the vehicle slow itself down. He was able to get stopped and turned around and made it home. Saturday, [XXX] we decided maybe it needed new brakes and took it for new brakes. New brakes and rotors all the way around did NOT fix the problem. The brake was like hitting a brick and would not stop the vehicle. I had the vehicle towed to a repair shop and they found that the vacuum system for the brakes went out. He also noticed that cam shaft was cracked. Upon research through the internet I found that this problem is common and a class action suit has been filed against GM for the same problem. I am unsure why this is not a recall as its a safety issue and my son could have been injured or injured someone else. This has been an EXTREMELY expensive repair for us! When they went to replace the cam shaft there were several parts of the cam shaft just blown all over the engine. We still have not found all of the missing parts. This has caused most of the seals to have to be replaced as well. I do not have a repair receipt yet as the vehicle is still in the shop INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

P0301 Error - Cylinder 1 Misfire. First the Check Engine light and Service Stabilitrack light turn on. Then seconds later, the car began to violently shake and sometimes the gas will not go resulting in the car being stuck in the middle of the road for about 60 seconds before moving again in stop-and-go traffic. These warning lights turn off and on. The dealer says this is the result of a plastic piece breaking due to general wear-and-tear and the only solutions are to replace the pistons or replace the whole engine. Multiple smaller repair shops say this is a known issue and it doesn't have any open recalls. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was in the freeway and out of nowhere an alert message popped up on the dashboard saying Engine power reduced. This made my car go from 65mph to 30 mph is the freeway luckily I was able to exit and go to the nearest gas station and was able to keep myself safe as others on the road but it could've easily gone very badly. The car won't go over 30 mph.

I will attach it to this message.

The Power Brake Vacuum Assist Failure nearly caused a wreck. The part failed while we were driving on [XXX] going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “Reduced Power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an HEB parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.
