PURCHASED THIS VEHICLE AND WITHIN FIRST DAYS DISPLAY SAID "SHIFT TO PARK" EVEN THOUGH I PUT THE CAR IN PARK. NEXT PROBLEM, PUT THE CAR IN REVERSE, DISPLAY SAID "SERVICE REAR VISION CAMERA." THESE ARE SIGNIFICANT SAFETY PROBLEMS FOR DRIVER AND OTHERS.

SERVICE BATTERY CHARGING SYSTEM NOTE CAME ON, JUST REPLACED THE ALTERNATER AND GOT A NEW BATTERY PUT ON. EVERYTHING ELSE IS GOOD AND THIS KEEPS COMING ON.

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.
