Power Train owner reports: Chevrolet Malibu years in the records

The records describe a possible crash, fire, injury, or loss of control.

“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 speed struggling to pick up. I paid the loan $16,000 off using what I had saved. I cant go out and purchase a new or used car.”

“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.”

“- started shutting shutting off at while in drive. - started having reduced power - started idiling high while driving - initially there was no codes - last night I drove, I put in drive gear but it was delayed so I had to keep moving from park to drive for it to full go into drive - the codes came P0325 P0505 P0507 P0700 P1101 P2714 After I was driving up an incline the car stopped moving forward and started reversing backwards. One other independent shop advised they were able to produce but couldn’t figure out the problem because no code were shown at the time. There has been many people having the same issues I started off with and I found the forum to file a report .”

“The component that failed is the internal microswitch/sensor within the gear shifter assembly. The specific part that requires replacement is often documented in General Motors Technical Service Bulletin (TSB) 19-NA-206 or 23-NA-119. The faulty component is available for inspection if the dealership removes the old part and retains it. My safety and the safety of others are put at risk because the vehicle often fails to register that it is fully in "Park," which prevents the vehicle from shutting off properly, potentially leaving it in accessory mode. This could lead to a dead battery, leaving me stranded. More importantly, the failure to confirm the 'Park' state introduces a risk of the vehicle not being securely immobilized, creating a roll-away hazard if parked on an incline. The problem has been confirmed by local Chevrolet dealership service centers (receipts available). The issue is identical to the defect that prompted official safety recalls for numerous other GM models, including the 2017-2018 GMC Acadia. Furthermore, the symptoms described match those outlined in the active class-action settlement for 2016-2019 Malibu owners (STPLawsuit.com).”

“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.”

“I was traveling down i-25 at 75 mph because that is what the speed limit here in Colorado. I was traveling south heading to Colorado Springs to visit family and i was entering near Castle Rock and my vechile would not go at all forward and it seemed as if I lost power to acceleration and I believe it was 2 or 3 lanes to exit off an off ramp as cars pasted me by honking their horns it was very scary as I pulled over to the side of the road letting it glide or coast to a stop very slowly I finally came to a stop.. as I have been reading some recalls due too a transmission issues for these types of vechiles I really hope I'm going about it right and someone reaches out to me about what it is that might be going on because even though my car does not have it listed by a Vin number I still believe that my 2019 Chevy Malibu has been subject to recalls for issues including a faulty rear seat belt retractor and a transmission problem that could lead to a loss of propulsion. The rear seat belt recall involves improperly secured retractors, and the transmission recall is due to a start-stop accumulator endcap with missing bolts, which could cause a leak and a loss of propulsion or a fire risk. And would like to have this addressed and or hits the right people concerning this not only for myself but safety for other people traveling at high speeds like myself that night... I was 5 days past my dealership warranty when I purchased the vechile from them and made it 6 days because I could get ahold of anyone on the 5 day when this incident occurred and then I called GM because I believe it would of fell under a drive train warranty but they said which was only 5 years warranty on this vechile from the day it was purchased its first time my vechile only has 82000 miles on it and I got it from a dealership here in Colorado with 64 or 62000 miles and since then I'm paying on a vechile that is no longer in service parked Sincerely and hopefully this reaches the right person...”

“Sunday, September 21, 2025, while on my way to church around 8:40am, while driving in traffic, car began to slow and then stopped (CAR WAS IN DRIVE, NOT IN PARK). The "Shift to Park" and ABS light appeared on dashboard. After the car completely stopped, and with other motorists blowing their horns behind me, I put the vehicle in park and was able to restart it. I immediately returned home and called a church member for a ride. I ALMOST HAD A HEART ATTACK WHEN THE CAR STOPPED IN MOVING TRAFFIC WHILE ACTIVELY DRIVING IT! I scheduled an appointment for a diagnostic and brought it in to the dealership on Monday, September, 22, 2025. It was kept overnight and two diagnostics were performed (they charged me for two diagnostics). They informed me that the solenoid assembly had to be replaced and that after performing a road test for the ABS, they did not find anything. Its very stressful in remembering what happened and that I COULD HAVE BEEN KILLED OR SOMEONE ELSE INJURED AS WELL, IF SOMEONE HAD RUN INTO ME AFTER THE CAR KILLED WHILE DRIVING IT!!!”
