2017 Chevrolet Malibu

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

The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the power steering was inoperable. The contact stated that the steering wheel seized, and the steering wheel was extremely difficult to turn. The “Service Power Steering” soon warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 125,544.

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 3,000.00 shame on them

In February 2023, we took the Malibu into the dealership for reduced engine power dashboard notification. Light went off when in shop, got the car back and light on once again. When at a red light that turned green, accelerated but car would not go over 20 MPH. Almost rear ended. Dealership replaced the vacuum pump gasket and seal. Fast forward one year later. Once again, reduced engine power notification came on again. Once again at red light, when light turned green, car wouldn't accelerate and was very close to being rear ended and difficult to make it through the intersection. Currently at dealer (1/18/24) with dealer having no idea what is wrong with car (today is 1/24/24). The dealer today stated it will be another 1-2 weeks. That will make it three weeks for a diagnoisis. With reduced engine power, it is very dangerous to drive a vehicle like this. Of course, there are hundreds of other complaints for this issue/make/model.

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.
