2016 Chevrolet Malibu limited

When I was driving my car with my child in it my break tightened up and I couldn’t apply them to stop I had to let my foot off the gas and let my car slow its self down safely. When I got my car home my husband looked at it and found out that my vaccum pump had went out and part of it broke off in the engine. This is very unsafe and this needs to be investigated because people can’t know when the vacuum pump is going to go bad this issue lays on gm and Chevy to make sure the parts they are using will hold up and be safe

Brake booster pump failed ( gm part # 12704586 ) Causing limited braking and severe damage to internal engine components, camshafts ,timing chain have been damaged This is a ongoing problem in which i have had this pump replaced at my expense several times. The problem stems brake booster pump is lubricated using the engine's oil . Booster pump has a small screen to filter oil, this filter can easily become clogged resulting in booster to run dry and grenade into top of engine. These pieces then interfer with camshafts and timing gears other components

When I put the car in park and try to turn the car off the Shift Park message comes on preventing me from cutting the car completely off. I put in back in drive or reverse then back in park it still dings and shows the message. I takes a number of repeating these steps for it to stop and turn off and this is happening every time I'm trying to turn the car off.

The contact owns a 2016 Chevrolet Malibu. The contact stated that while shifting into park(P), the vehicle failed to recognize that the transmission was in park(P). The contact had to manipulate and maneuver the gear shifter several times before the vehicle recognized that the gear shifter was in park(P). The message to "Shift-to Park" was illuminated. While receiving a routine oil change, the vehicle failed to start. The mechanic charged the battery; however, the vehicle failed to start. The vehicle was inspected, and it was determined that the was experiencing the "Shift to Park" failure. The contact found information of NHTSA Campaign Number: 16V502000 (Electrical System, Power Train); and linked the failure to the recall. The dealer was contacted and confirmed that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not made aware of the failure.

Stability track warning randomly appears while driving and spontaneously causes total brake failure and the brakes fail to slow or stop vehicle. It has newer brakes but it’s very dangerous to drive. Currently being sent to Chevrolet dealership

The contact owns a 2016 Chevrolet Malibu. The contact stated while driving on several occasions at various speeds, the check engine warning light illuminated, and the vehicle lost power. Additionally, the message “Engine Power Reduced" was displayed. The vehicle was taken to an independent mechanic and was diagnosed and determined that the throttle body sensor needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 107,000.

I am filing a complaint regarding ongoing and worsening issues with my Chevrolet vehicle, which appear to point to broader defects involving the engine and electrical systems. Months ago, while driving, the car suddenly lost power and displayed "Engine Power Reduced." I had to keep using it due to work needs. Over time, it hesitated more during acceleration and felt increasingly unsafe. When I finally brought it to a Chevrolet service center, I was told the issue involved the pistons. The vehicle also regularly shows a "Shift to Park" warning even when the gear is in Park, raising concerns about the transmission's reliability. The power loss continues, especially when going uphill — again triggering the "Engine Power Reduced" alert and dropping the speed to no more than 35 MPH. A diagnostic showed a P0302 code for a cylinder 2 misfire. The radio head unit, already replaced once under warranty, failed again after just 9 months. Prior to the worsening idle and gear issues, I also received network-related codes involving the ECM and transmission computers. Although I’ve replaced the alternator, the car still shows "Service Electric System" warnings, suggesting ongoing electrical problems. I also noticed GM’s N182195660 campaign involving predictive monitoring for Stochastic Pre-Ignition (SPI) on SCP platforms. My car has the 2.0L turbo engine, and I’m concerned it may be experiencing SPI or coolant intrusion issues affecting overall performance and system integrity. I’m requesting that Chevrolet investigate these problems thoroughly and determine whether my vehicle qualifies for recall, extended warranty, or defect coverage. These issues are persistent, serious, and deserve immediate attention. Thank you for your time. I hope to see resolution soon.

Shift to park message and park not fully engaging. This caused the vehicle to roll back when parked on an incline.

Took my car to Chevy dealership to diagnose my car, as it was rough idling, causing hesitation, and knocking... all while the check engine light was on. They showed me two codes my car was giving from the check engine light. They said he would look further into it. They told me I needed a tune up, though I had gotten a tune up 4 months prior. They fixed some things and charged me over $4,000. The day I drove off the lot, the problems were still present. On my way home going about 50 mph, my car slowed down and the engine reduced power illuminated. I kept driving because I needed a car for work. The car continued to decline and acted like it didn't want to accelerate when pressing the gas. I finally took it back into chevy, and they told me it was my pistons. I'm 90% sure there is a defect that they won't tell me about, or the won't fix. I've had the car 2 years. Now the car won't run.

I am writing to report a serious and unacceptable issue with the exterior paint and clear coat on my 2016 Chevrolet Malibu. The clear coat has become dull and faded on the hood and roof, and the side panels are beginning to chip and peel, despite regular washing and maintenance. This paint deterioration started well before what would be expected in a properly manufactured vehicle finish, especially for one that has been well cared for and is only a few years old. The vehicle has never been in an accident, and the finish failure appears to be due to a defect in the clear coat or paint application process at the factory. This not only affects the appearance and value of the vehicle, but also raises concerns about long-term body protection. Once the clear coat is compromised, the base paint and metal underneath are more susceptible to rust and corrosion. There are countless reports online of other GM vehicle owners experiencing similar issues, and I believe this should be investigated as a widespread manufacturing defect. I request that GM address this issue, either through a recall or a goodwill repair/paint reimbursement program. Vehicle Details: Year: 2016 Make: Chevrolet Model: Malibu E2 Color: Black Thank you for your time and attention. I hope to see GM stand behind its product and take responsibility for this defect.

To whom it may concern, I am writing to formally report a recurring safety-related issue with my 2016 Chevrolet Malibu. The vehicle consistently displays a “Shift to Park” warning message, even when the gear selector is properly in the Park position. This malfunction prevents the car from turning off completely and poses a serious safety and reliability concern. This issue first occurred while the vehicle was under warranty, and the dealership performed a repair. However, the problem has returned, and my warranty has since expired. Despite the previous fix, the issue continues to persist. This malfunction is widely documented among other 2016–2019 Chevy Malibu owners and appears to stem from a design or manufacturing flaw in the shifter assembly or park switch. I am concerned that this defect could: Prevent the vehicle from being securely parked. Lead to battery drain due to the vehicle not shutting off. Pose a risk if the driver believes the car is in park when it is not. I am requesting that Chevrolet consider this a safety defect and either recall the affected vehicles or offer extended coverage for repairs. I also ask that NHTSA investigate this issue further as it compromises the safety, reliability, and proper functioning of the vehicle. Thank you for your attention to this matter. I would appreciate any assistance or updates regarding how this issue will be addressed.

Shift to park message on odometer after vehicle is already in park

Happened around 46000 miles after receiving a recall notice in the mail about the pedal positioning sensor causing a reduced engine power signal, and immediately reducing speeds on the interstate. Local Chevy dealership replaced. Fast-forward 80K miles and the same incident is happening, however likely not going to be covered by GM. Same message, same code being detected.
