What is the class action lawsuit on the Chevy Malibu?

Question

VanZoey · Accepted Answer

The class action lawsuits against the Chevy Malibu primarily address three major defects: a persistent "Shift to Park" error, premature brake vacuum pump failure, and sudden "Reduced Engine Power" incidents. Owners of affected models may be eligible for cash payments, repair reimbursements, or free repairs under court-approved settlements. The most prominent settlement covers 2016-2019 models for the "Shift to Park" issue, offering a $550 cash payment and reimbursement for past repairs.

The "Shift to Park" Defect (2016-2019 Models) This is the most widely recognized issue. A lawsuit alleged that a faulty shifter assembly or micro-switch prevents the vehicle from recognizing it is in Park. This causes the engine to not turn off, the gear selector indicator to flash, and a "Shift to P" message to display. A settlement provides concrete benefits:

Cash Payment: A $550 payment for owners who experienced at least two related repairs.
Reimbursement: Up to $1,400 for out-of-pocket repair costs before the settlement.
Warranty Extension: An extended warranty covering this specific repair for 10 years or 150,000 miles from the original purchase date.

Brake Vacuum Pump Failure (2016-2018 Models) A separate lawsuit claims a defective brake booster vacuum pump can fail prematurely. This leads to a hard brake pedal, significantly increased stopping distances, and a loss of power brake assist, creating a serious safety risk. The National Highway Traffic Safety Administration (NHTSA) has recorded numerous related complaints. While a settlement was reached, it primarily provided for reimbursement of past repair expenses for owners who paid for replacements.

"Reduced Engine Power" & Throttle Issues (2016-2018 Models) Another class action targets defective accelerator pedal position sensors and electronic throttle body controls. The defect can cause the vehicle to suddenly enter a "limp mode" with drastically reduced power, accompanied by a "Engine Power is Reduced" warning. This poses a hazard when accelerating, especially into traffic or on highways. This case is ongoing, with plaintiffs seeking a recall or extended warranty.

How to Check Your Eligibility and File a Claim Eligibility is strictly tied to your Vehicle Identification Number (VIN) and model year. Do not rely solely on general lists. First, visit the official settlement administration websites. For the "Shift to Park" settlement, search for In re: GM "Shift to Park" Litigation. These sites have VIN lookup tools and claim forms. Second, check your mail or email for a direct notice from the settlement administrator, which is the most definitive way to know you are included. Finally, you can search the NHTSA database using your VIN to see all recall campaigns and technical service bulletins related to your specific Malibu, which can inform you of known issues.

I just got my check from the "Shift to Park" settlement last month. My 2017 Malibu had that annoying issue where it wouldn’t recognize it was in Park—I’d be sitting there jiggling the shifter for minutes. I took it in twice under the regular warranty. When I got the postcard about the class action, I submitted my repair receipts online. The process was straightforward. A few months later, a $550 check showed up. It didn’t make the car perfect, but it felt like some acknowledgment of the problem. If you’ve had this fix done, definitely look into it.

As a mechanic at an independent shop, I’ve seen a stream of these Malibus with the same problems. The “Shift to Park” is incredibly common; we replace that shifter cable assembly all the time. The brake vacuum pump issue is the more concerning one from a safety standpoint. When it fails, the pedal gets rock hard and stopping power plummets. Customers are often shocked by the repair cost. My advice to owners is to be proactive. If you feel your brakes getting unusually stiff or hear a loud hissing noise from the booster, get it checked immediately. Don’t wait for a failure. Also, keep all your service records organized. Those receipts are your ticket to reimbursement if your car is part of a settled lawsuit.

You might be part of a class action if you own a 2016-2019 Malibu with the “Shift to Park” glitch, or a 2016-2018 model with brake or sudden power loss problems. Don’t assume GM will contact you directly. You need to act. Find your VIN (on the dashboard or driver’s door jamb). Search for “Chevy Malibu shift to park settlement website” online. Enter your VIN on the official settlement page to check eligibility. File a claim before the deadline passes. For the brake pump or engine power lawsuits, you may need to join or wait for a settlement. Check with the law firms handling those cases or the NHTSA website for updates.

Let’s break down what these lawsuits really mean for you as an owner. They’re not about getting a huge payout; they’re about making GM responsible for widespread flaws. The “Shift to Park” settlement is the clearest win: cash back if you struggled with that issue. The brake pump lawsuit is about a genuine safety defect—it’s about forcing a fix for a dangerous problem. The “Reduced Engine Power” case is similar, addressing a fault that can leave you stranded. The key is documentation. If your car has any of these symptoms, report it to the NHTSA website. That complaint data strengthens cases. Then, keep every single repair order. Whether it’s a reimbursement or a future recall, that paper trail is your evidence. These class actions move slowly, but they do result in extended warranties and reimbursement programs that you can actually use. Stay informed through the official settlement admin sites, not just forum rumors.
