Cam-driven Brake Booster Vacuum failure without warning. My engine died, my brake pedal and steering wheel stiffened, while in moderate traffic. I had use excessive brake force to slow my vehicle to a stop. Currently have 78,012 miles as it is sitting in the repairs shop.

2018 Chevy Malibu over 5 times this happens since we bought it brand new it has "Reduced Engine Power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to go over 30 mph. This same problem happens on our 2017 Chevy Malibu that we bought brand new since we owned it too and I have already put in a complaint filed today! This is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "Reduced Engine Power" Limit. GM needs to recall these Malibu's and fix the dangerous "Reduced Engine Power" error because it's dangerous to the driver in rush hour traffic and on the tollway traffic with no ability to go over 30 mph. All these Malibu's need to be fixed properly and its GM's responsibility to ensure safety for their customers lives.

The car continuously is throwing a code P2138 and a warning comes up on dash saying reduced engine power. This happened 6 times to me yesterday wherein I was traveling on 1 lane winding roads in my neighborhood so the speed drops from wherever it is down to 10mph instantly. On 1 lane roads in the area where I reside there’s no safe place to pull over. This is extremely dangerous and a massive safety hazard and risk to my life!

While picking my kids up from school my car suddenly lost braking ability and I heard a weird noise under the hood. Like it needed an oil change. Tension from the brakes and couldn’t stop when tried. Definitely gained anxiety from this event. I did get the part replaced however I’m concerned for the engine and any possible damage that may have been caused. I still have the original part to the vehicle as well.

Suddenly loss of power at cruising speeds. Trouble with acceleration and loss of power. Unresponsiveness from the engine. The Check Engine Light illuminate, OBD2 call for code P2138. The speed stuck at 30 m/h on the 65 m/h thruway which cause unsafe situation for me and other drivers on the road. When googling this issue on the internet, reviews show it is common problem in this model. GM refuses to fix this issue at their cost because "according to the VIN number of my car, it is not included in the recall list" which it does not make sense.
