2019 Chevrolet Malibu transmission problems

Filed Oct 20, 2026 · Engine, Transmission · CA

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.

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 Service Bulletin is not the same as a recall or an extension of the vehicle's warranty. I am not claiming that GM is necessarily obligated to repair the vehicle under the expired warranty. Rather, I believe GM's own technical documentation demonstrates that this is a recognized issue involving a specific component and is not simply an ordinary maintenance item that a customer should reasonably expect to replace at 39,000 miles. The approximate cost of this repair is $1300 for a failed $40 part!! Even GM changed the design of this component because in years past and newer years this part replacement was a 20 minute job, not a 5 hour complete replacement of the valve cover! Failure to repair this faulty design could lead to excessive oil loss and immediate loss of power due to the engine ceasing.

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.

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...
