2018 Chevrolet Malibu

While driving th vehicle the component that ruptured was the vehicles vacuum brake booster pump which connected directly to the engine. The ruptured caused shards of metal to be launched into the engine resulting in no brake power and needs an engine swap. There was a recall on this model vehicle for the Pedal sensor malfunction that results in the cars engine going into a reduced power mode abruptly and suddenly while driving. This malfunction has occurred on this vehicle and I was not aware of this vehicle models recall history but it stated that the recall was successfully closed out in 2020. I purchased my 2018 Chevy Malibu in the year 2021 and the issue still persist. I am not confident that the recall on this vehicle was either fully completed or successfully fixed before purchasing. The car is now at the dealer and the repair team explains the vehicle needs a new engine. I questioned about the pedal sensor malfunction and asked if it was possible that this malfunction sending the vehicle into a reduced power mode so suddenly could have effected or cause wear and tear on brake booster pump connected to the engine. The dealers repair team wasn’t confident in saying it wasn’t possible. This is likely a design issue and if a recall was completed and I was sold a vehicle uninformed of this potential issue but the malfunction still persisted I do not believe I should have to cover the full cost of repairs for this chain of events. This malfunctioned put me at danger and if it had occurred while my wife and 3 children were in the car it could have been life threatening not only to us but the other drivers around as well. With the engine reduced you can’t accelerate and with the booster pump ruptures mid drive you lose all brake power. It is hard to understand the faulty design in this but I have read reviews that others have had the same issue so I do not believe I am alone in this.

Vehicle suddenly went into reduced engine power mode and nearly caused a crash. We pulled off to the side of the highway. Turned the car off and waited for about 5 minutes with our small children in the back seat. Restarted the car and check engine light remains on but the reduced engine power warning turned off. This just happened today and have not been to the dealership. Hoping Chevy recognizes this safety issue and issues a recall as many others have reported the same issue.

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 60 MPH, the vehicle stalled. The contact stated there was no warning light illuminated. The contact stated that the vehicle was left on the side of the roadway. The contact called the dealer where the vehicle was purchased and was advised that he had to pay to have the vehicle towed. The vehicle was not taken to the dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact was aware of an open recall on the vehicle, NHTSA Campaign Number: 19V642000 (Electrical System, Fuel System, Gasoline, Engine). The failure mileage was unknown.

When putting my vehicle in park to turn off the car, a warning light comes on to put vehicle into park. The vehicle is already in park and am unable to turn off the vehicle. In order to turn off the engine I must repeatedly turn it on and off and hit the gear shifter multiple times. This problem is becoming more and more frequent. I see numerous other 2018 Malibus in the complaint section reporting the same issue. Come on Chevrolet fix this problem!

REDUCED POWER TO ENGINE . Previously had recall for this issue, which was replaced by Chevy service center. About a year later I had the same problem but had to pay out of pocket because there were no active recalls on the issue. As of today, I am receiving the same “REDUCED POWER TO ENGINE” error and check engine light keeps coming on. This happens randomly but frequently almost every single day. Error will shut off after restarting car and then happens again not long after. I’ve had this issue with multiple Chevy Malibus that I have owed and there is currently a class action lawsuit against GM for this exact issue.

Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it’s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I’ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model,year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle.

Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well.

Since I got the car, if I let it go in auto stop, it has a hard time accelerating when I push the gas. It has gotten worse and now it has a hard time accelerating in general. When I push the gas it sounds really loud like it’s struggling to go. I realized this is a safety issue for me and others when my car wasn’t going at the light of a busy intersection, or when I’m getting onto a highway and my car isn’t picking up speed. This makes it scary for people already on the highway as Iam causing them to brake unexpectedly. Every time my check engine light comes on I take it to the dealership. It’s been taken in for repairs multiple times but this issue still keeps coming back.

The contact owns a 2018 Chevrolet Malibu. The contact stated while operating the vehicle, the message "Engine Power Reduced" was displayed and the vehicle would not properly accelerate above 30 MPH. Additionally, while depressing the brake pedal, the vehicle failed to immediately stop, and the pedal was firm when depressed. The vehicle was later towed to the local dealer. The cause of the failure was unknown. The manufacturer was not yet notified of the failure. The failure mileage was 50,000.
