2019 Chevrolet Malibu 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 purchasing the vehicle, the following morning while waiting at the school drop-off line with her foot on the brake pedal, there was an abnormal boom, and several warning lights illuminated and flashed on the instrument panel. The occupants inside the vehicle assumed that the vehicle was struck from behind. The vehicle attempted to surge and revved and started to choke and shut off. The vehicle was shifted into park and the ignition key turned to the off position. The vehicle was restarted but failed to move. The engine, traction control, and the radio were blinking. The vehicle was shifted to first gear but was moving slowly. The vehicle stalled and was restarted, but the failure recurred. The engine light remained illuminated, but the screen was dimmed. The vehicle was turned off. The contact associated the failure with TSB: 21-NA-045. The dealer was called and a voicemail was left. The vehicle was driven to the service center and the contact waited for 20 minutes to allow the vehicle to cool down and then restarted the vehicle. The gear shift indicator was not lit. The contact was able to…”

“Since 2024/2025 car has been malfunctioning, I’ve had it checked out but it just got worse and nothing was fixed l, it is I driveable and very unsafe. When driving it abruptly stops like it’s crashing Messages that pop up (Multiple ones at one time flashing as well) - service “ESC” -“service power steering drive with care” -“shift to park” -“low fuel” (but car has gas in it) - check engine light on -all lights flashing at once while jerking -car stops abruptly when you’re driving it -radio blacks out while driving -dashboard blacks out as vehicle is running -jerking while trying to stop -sensor malfunctions -transmission slippage -engine still on and running sounds like it’s cooling down and smells of it as well”

“Due to the vacuum pump failing during driving, metal shards broke inside of the car and went into the engine destroying it completely. Now i need a whole new engine”

“My 2019 Chevrolet Malibu has severe safety defects involving the engine, powertrain, and speed control. The vehicle will sometimes accelerate on its own with my foot off the gas, and other times it loses all power while pulling into traffic. This creates an immediate risk of a crash. Multiple diagnostic codes appear repeatedly, including P0299 (turbo underboost), P0101 (mass air flow performance), P1101 (intake airflow performance), and P0506 (idle control RPM too low). The charge-air hose repeatedly blows off the throttle body while driving, causing sudden loss of power. The vehicle was sold to me by a dealer as safe and reliable, but these defects appeared shortly after purchase. The unintended acceleration and sudden loss of power make the car dangerous to drive. This appears to be a serious mechanical and safety-related defect that could cause an accident.”

“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…”
