The most widely reported legal action centers on the Malibu’s transmission, alleging a defective 9-speed automatic that can shudder, slip or lose power and create safety risks for drivers.
In more detail, plaintiffs have filed class-action and multi-district litigation across federal courts asserting that General Motors knew about the defect or failed to disclose it adequately, and that the problem affects a subset of 2016–2019 Malibu models (and, in many cases, other GM models that use the same transmission). The cases seek damages, repairs, refunds or replacements, and sometimes extended warranties or other remedies.
What the lawsuits allege
These suits generally describe a pattern of mechanical failures that occur at various mileages and can lead to unexpected loss of propulsion or dangerous driving conditions. Below are the core claims commonly raised by plaintiffs:
- Defective transmission: the 9‑speed automatic in affected Malibu models allegedly suffers from design or manufacturing flaws that cause shifting problems, shuddering, slipping, or failure to engage gears.
- Safety and reliability risks: the transmission issue can cause sudden loss of power, surging or inconsistent acceleration, and hard shifts that raise crash concerns.
- Failure to repair or warn: plaintiffs contend GM did not adequately diagnose, inform customers, or provide timely recalls or remedies under warranty programs.
- Economic harm: owners claim reduced resale value, costly repairs, and out-of-pocket expenses related to the defect.
These are typical elements, but the exact allegations and remedies vary by case and jurisdiction.
Models and scope affected
Before reviewing specifics, it's helpful to understand the scope. The suits generally focus on Malibu model years around 2016–2019 that used GM’s 9‑speed automatic transmission, and some cases extend to other GM vehicles with the same transmission family. The exact VIN ranges and service records cited in complaints determine eligibility in each action.
- 2016–2019 Chevrolet Malibu models equipped with the Hydra-Matic 9‑speed automatic transmission.
- Related GM models sharing the same transmission family (e.g., certain Cruze, Camaro, and other GM vehicles) often appear in the same or related lawsuits.
- Occurrences of shudder, hesitation, or loss of power documented by plaintiffs and, in some cases, confirmed by dealer service bulletins or warranty claims.
The litigation status varies by case; some matters have seen motions settled or dismissed, while others remain active in court or are being reviewed in mediation.
GM’s response and the legal status
GM has publicly defended the quality of its vehicles while engaging with regulators and plaintiffs in various channels. In general terms, the company has:
- Issued service bulletins and recalls or warranty extensions in some markets related to transmission performance.
- Contested allegations where it says the vehicles meet safety and reliability standards and that any claimed defect does not pose an ongoing or systemic risk.
- Participated in settlements, contingent on case-by-case terms, for certain customers or at the class action level where negotiated.
As with most consumer litigation, the outcomes depend on the jurisdiction, the specific model and VIN, and the progress of discovery, expert testimony, and potential settlements.
What Malibu owners can do now
If you own a 2016–2019 Malibu or another GM vehicle with the same transmission family, you should be proactive if you notice transmission symptoms or if you’re seeking information about legal rights. A short guide:
- Check your vehicle’s VIN against GM recall and service bulletin databases to confirm any active notices related to the transmission.
- Document symptoms such as shuddering, jerking, hesitation, or loss of power promptly and keep records of service visits and repairs.
- Contact your dealer or GM customer service to inquire about warranty coverage, service options, or potential recalls and the status of any related class actions.
- Consult lemon law or consumer protection counsel if you believe you’ve suffered economic or safety harms from the defect.
Because lawsuits progress at different speeds and outcomes vary, owners should seek personalized advice and monitor official agency updates for recalls and safety notices.
Summary and outlook
The core legal issue surrounding the 2018 Chevrolet Malibu centers on alleged defects in the model’s 9‑speed automatic transmission that can cause shifting problems, reduced power, and safety risks. Plaintiffs in several class‑action and MDL actions allege that GM did not adequately warn owners or remedy the defect. GM has responded with recalls, service notes, and, in some cases, settlements or warranty programs. The exact status depends on the case and jurisdiction, and ongoing oversight by regulators and courts continues to shape any remedies for affected owners.
Bottom line: if you own an affected Malibu, stay informed about recalls, monitor for transmission symptoms, and seek professional guidance if issues arise.
