2018 CHEVROLET MALIBU

SEAT BELTS:CRITICAL FASTENERS

General Motors, LLC (GM) is recalling certain 2016-2021 Chevrolet Malibu and 2019-2021 Cadillac XT4 vehicles. The rear seat belt retractors may be improperly secured with loose or missing fasteners.

Risk: An improperly secured seat belt retractor may not function properly in a crash, increasing the risk of injury.

POWER TRAIN:AUTOMATIC TRANSMISSION

General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Cruze and Buick LaCrosse, 2018-2020 Chevrolet Equinox, Chevrolet Traverse and GMC Terrain, 2018 Chevrolet Malibu, 2019-2020 Buick Encore, Buick Enclave, Cadillac XT4, Chevrolet Blazer and GMC Acadia, and 2020 Cadillac XT6 vehicles. The start/stop accumulator endcap may have missing bolts.

Risk: Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.

FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:INJECTORS

General Motors LLC (GM) is recalling certain 2018 Chevrolet Malibu vehicles equipped with 1.5L turbo engines. An error in the Engine Control Module (ECM) software may result in the fuel injectors being disabled.

Risk: Disabled fuel injectors would prevent the engine from starting and may cause a stall, increasing the risk of a crash.

AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION

General Motors LLC (GM) is recalling certain 2016-2018 Chevrolet Malibu vehicles. During servicing, a Passenger Presence System (PPS) may have been installed that was not correctly calibrated to the vehicle's seat type. As a result, the PPS may not properly identify an adult passenger from a child passenger in the front passenger seat, potentially causing the air bag to not deploy when it should, or causing the air bag to deploy when it shouldn't.

Risk: In the event of a crash, improper air bag deployment can increase the risk of injury.

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

General Motors LLC (GM) is recalling certain 2015-2018 GMC Canyon, 2016-2017 Buick Envision, 2016-2018 Chevrolet Colorado and Malibu, 2017-2018 GMC Acadia, 2018 Buick LaCrosse, Cadillac ATS, Chevrolet Equinox, and GMC Terrain vehicles. The high pressure fuel pump may detach from its mounting flange, possibly resulting in the pump damaging the high pressure fuel line.

Risk: A damaged fuel line can create a fuel leak, increasing the risk of a fire.

1. This case refers to a 2018 Chevy Malibu. In October 2021, the (gear shift) transmission control system was found faulty and was replaced with an N-CONTROL in the gear shift. Again, in September 2025, the same issue happened, this time replacing the N-CONTROL again as well as the N-HARNESS. Yes, can be available upon an inspection request. 2. This component directly affects how the car recognizes when it is in Park. When it malfunctions, it can confuse the vehicle’s electronic systems and potentially prevent the car from shutting down properly, engaging the shift lock, or starting safely. This creates a safety risk for both me the driver and others around my vehicle. Since this is a recurring issue as well as other 18 Chevy Malibu's I don’t believe this is normal wear and tear. Having to replace the same system twice in such a short period suggests a recurring failure or a design flaw. 3. Yes, the problem has been confirmed twice by Chevrolet dealerships on both occurrences. 4. Yes, the component was inspected by two Chevrolet dealerships during both occurrences. 5. Had warning message "shift into park" both times in the month the car was taken in to be inspected.

Ever since 2020 I’ve that shift to park issue. Luckily my car was under warranty the first time and was resolved only for the problem to reoccur again within 2 years.

I am writing to formally report a serious safety concern with my 2018 Chevy Malibu related to the brake booster vacuum pump. My vehicle has exhibited dangerous symptoms, including a hard brake pedal and reduced braking power, which I’ve now learned may be connected to a known defect affecting 2013–2022 Malibu models. These issues have significantly compromised my safety and that of others on the road. I’ve had to deal with sudden braking difficulties, and the repairs have caused financial stress I was not prepared for. I am now aware of the pending class action lawsuit (Johnson v. General Motors LLC) that details this same problem.

My vehicle will randomly tell me to "shift to park". Happens at least daily. I bought my car in October 2024 I do plan to take it in with my limited warranty. I don't think I should have to cover a rental for however long it will take them to see it happen, diagnose the problem, possibly wait for part(s) to come in them fix it. On top of running the chance it'll happen again in the future and possibly have no warranty as well as rental fees. I think it's very wrong that GM won't recall this and refuses to just fix it all.

I am filing a complaint regarding a brake vacuum pump failure in my 2018 Chevrolet Malibu. The failure of the vacuum pump led to a complete loss of brake assist, making the brake pedal significantly harder to press. This issue directly resulted in a complete loss of braking ability, which posed a serious safety risk while driving. The vacuum pump in these models is camshaft driven, and its failure caused damage to the camshaft. This issue is documented under GM Technical Service Bulletin PIP5835 and is known to affect certain 2016-2022 Chevrolet Malibu models equipped with the 1.5L LFV engine. The brake failure due to this issue could have led to a life-threatening accident, and I am deeply concerned that other drivers may experience this same risk. Despite reaching out to GM and the dealership, goodwill assistance was denied for this known defect. I believe this is a major safety hazard that needs to be addressed immediately. Vehicle Mileage ~120,000 Repair Estimate: $2106 for camshaft, vacuum pump, and related components Incident: The brakes became unsafe leading to a dangerous life threatening driving situation

I was going about 75 mph on the express way with one lane open due to construction. My car started losing power.I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop has quit working. I spoke with 5 visitors at Chevrolet and we all were having the same issues. This is something ongoing according to my research on this particular vehicle and should be recalled asap.
