2019 Chevrolet Malibu power train problems

“The vehicle experiences sudden transmission slipping, severe shuddering, and an unexpected loss of forward drive power while in motion. Specifically, while attempting to accelerate from a complete stop / merge onto the highway, the engine revs but the vehicle fails to accelerate properly or suddenly loses acceleration entirely. This creates a severe and immediate safety hazard as it leaves the vehicle moving incredibly slowly or stranded in active traffic, creating an imminent risk of a rear-end collision. The dealership has been unable to provide a permanent remedy.”

“The contact owns a 2019 Chevrolet Malibu. The contact stated that after parking and attempting to turn off the vehicle, the gear shifter was shifted to park(P) however, the vehicle failed to recognize that the vehicle was in park(P), and the vehicle failed to turn off. During the failure, the message "Shift to Park" was displayed and the vehicle idled for approximately 15 minutes before independently turning off. The cause of the failure was not yet determined. The manufacturer and local dealer was notified of the failure, but no assistance was provided. The contact was notified of TSB: PIT5616A; and associated the failure with the TSB. The failure mileage was approximately 65,000.”

“I understand that the vehicle is outside of its original warranty period. However, I do not believe that the expiration of the warranty should automatically make me responsible for a component failure that occurred at only approximately 39,000 miles. The PCV valve and orifice are not routine maintenance items that I would reasonably expect to require replacement at such low mileage. Unlike tires, brake pads, batteries, or other components that are expected to wear out and require periodic replacement, the PCV system is an integral part of the engine's emissions and crankcase ventilation system. A failure at only 39,000 miles seems premature and should not reasonably be characterized as ordinary wear and tear. More importantly, GM itself has acknowledged problems involving the PCV system in Chevrolet Malibu vehicles. GM Technical Service Bulletin and TSB 18NA246 and TSB 20-NA-047 specifically addresses plugged PCV orifices on 2016–2022 Chevrolet Malibu models and provides a diagnostic and repair procedure for this condition. The bulletin identifies the PCV orifice as the causal part associated with the condition being addressed. I recognize that a Technical…”

“The first problem with my car was the tire pressure monitor. The location of each tire was wrong on the informant section. Soon after purchasing the car when ever I would park the car would not shut off and the DIC would display Shift to park message. Around 6 months after the purchase the brake pedal was getting harder the press down on and within a week from that while driving home from work the car completely shut off in the middle of traffic. It wouldn't start leaving me stuck on a busy street with heavy traffic blocking use of the lane. After 10 minutes it started back up and I barely made it into a parking lot of a shopping center with it shutting off again before I can park. I had to get a tow. I didnt go to an authorized dealer. I took it to a certified mechanic and had to replace the brake vacuum booster. The motor had to be cleaned out due to broken metal that got inside. After that repair car seemed okay until March 2026. The car now is in high idle and struggles to pick up speed. The message on DIC says engine power reduced. On the freeway the car can be going with the flow of traffic then suddenly engine power is reduce rpms go up high and it drops…”

“The contact owns a 2019 Chevrolet Malibu. The contact stated that upon shifting to park(P) and attempting to turn off the vehicle, the message "Shift to Park" was displayed. While investigating the failure online, the contact became aware that it was a common failure, and there was an ongoing Class Action Lawsuit related to the failure. The dealer was notified of the failure and informed the contact that the VIN was not included in a related recall. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 91,000.”

“Year 2019, code P1101- vehicle hesitates while drive, will reduce power while driving, while sitting idle at a stop the car will die and I will have to restart the vehicle. Multiple times while driving on the highway at 70mph my car has all of a sudden either reduced power causing the car to jerk and shudder very hard or has lost all power completely and forced me to pull over while avoiding other drivers on the road. SOMEONE IS GOING TO DIE BECAUSE OF THIS!!! THIS NEEDS TO BE ADDRESS AND RECALLED ASAP TO GET IT FIXED. I am not in a financial spot to just go buy a new car and I shouldn't have too either. I'm scared to even drive 10 miles down the road to take my children to daycare/school because of how bad it is.”
