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. The car is available for inspection upon request, I seen a PDF in the nhtsa website of a special coverage adjustment for loss of continuity within acceleration pedal position circuit. 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.

On numerous occasions while driving on highway my dashboard will display reduced engine power and engine light comes on. My traction control light also comes on. Car loses power quickly and will not accelerate. I-??ve had to pull over numerous times almost being hit by cars behind me. Took it to get repaired and had to have fuel pump replaced as wires had melted to side of pump. Three months later same problem happened. This car is scary to drive

Ice and sludge accumulated and froze causing the CAC system to fail resulting in engine issues, performance loss this was caused from GM poor design of a shield that they are aware of. GM knows that this can happen and have now designed a new shield to prevent this from happening but it is at the owner-??s expense to fix. If GM knows that this will happen they should fix the issue I am now out of pocket $3,000 shame on them

Engine reduced power while driving in traffic car gets no power to accelerate and engine light also on.

- Milwaukee, WI, USA

My car displayed "reduced engine power" and slowed down on the highway while I was doing 65mph. My car would not accelerate past 20mph. There were no issues with my vehicle, and this happened out of nowhere. It caused a lot of other drivers to have to swerve around me, and drastically reduce their speeds as well in order to avoid collision. This was highly unsafe and now I can not safely drive my own car.

Gas pedal locked up can-??t accelerate

- Haddon Township, NJ, USA

Error message reads "Engine Power Reduced". I was on the highway and suddenly the engine gives out and only lets me go to a max capacity of 20 mph. I able to safely remove myself to the side of the freeway. A week later without moving my vehicle I checked to see the status of my car and the error message removed itself. It's been over a year now with my engine power coming and going, just as fast as it comes, it goes-- making driving very unreliable and unsafe to step onto the road. Apparently I'm not the only one with this concern according to [XXX], a class action lawsuit has been charged against Chevrolet in The Rothschild v. General Motors LLC Chevy Malibu Class Action Lawsuit is filed in the US District Court for the Eastern District of New York under case number [XXX].

My dash warning lights came on and the engine shut off. The battery voltage seems fine, and the car will start but only run for a short time. I cannot drive it for fear of stopping on a highway or main road.
