Meet Our GM Transmission Lawsuit Attorneys

Drivers across the U.S. have reported serious problems with certain GM vehicles, including Chevrolet, Cadillac, and GMC models. These vehicles are equipped with transmissions that may cause shaking, hesitation, gear-shifting failures, and sudden loss of power.

While GM has sold these vehicles for years, many consumers allege the company failed to disclose the risks or offer adequate repairs. These issues don’t just damage vehicles—they can create safety hazards on the road and leave owners with thousands in repair bills.

If you owned or leased one of the following vehicles during the defect period and experienced transmission problems, you may be eligible:

• 2018–present Chevrolet Suburban
• 2018–present Cadillac Escalade
• 2018–present Chevrolet Tahoe
• 2018–present GMC Yukon Denali
• 2019–present Chevrolet Silverado (1500+)
• 2019–present GMC Sierra (1500+)
• 2017–2024 Chevrolet Camaro (including ZL1, V6)
• 2019–2020 Cadillac CT6
• 2020–present Cadillac CT4
• 2020–present Cadillac CT5
• 2020–present Chevrolet Silverado HD / GMC Sierra HD (10L1000 “Allison”)

The reported defects often go beyond inconvenience and can create dangerous driving conditions. Common issues include:

• Severe vibrations when accelerating (“shuddering” or “chugging” sensation)
• Gear shifting failures that cause hesitation or jerking
• Sudden loss of power while driving
• Loud noises, grinding, or clunking from the transmission
• Wheels locking or seizing up
• Full transmission replacement required, sometimes costing thousands of dollars

If you experienced one or more of these issues, you may qualify to join the ongoing litigation against GM.

You may have a claim if:

• You owned or leased an eligible GM model (Chevy, Cadillac, or GMC) during the defect period.
• Your vehicle experienced documented transmission problems, such as those listed above.
• You paid out of pocket for repairs, replacements, or related costs.
• You have not already been compensated or settled a claim related to this issue.

Even if you no longer own the vehicle, you may still be eligible depending on your history of ownership or leasing.

Yes. GM is under legal scrutiny for allegedly selling vehicles with defective transmissions and failing to provide adequate warnings to consumers. Drivers have filed lawsuits across the country, claiming that GM was aware of the defect yet continued to sell vehicles without a recall or a sufficient remedy.

The litigation seeks compensation for repair costs, diminished vehicle value, and related financial losses. Cases like these may be consolidated to streamline the legal process and strengthen consumer claims.

If successful, compensation may include:

• Repair and replacement costs for the transmission
• Diminished value damages if your vehicle’s resale value drops due to the defect
• Out-of-pocket expenses, including towing, rentals, and diagnostics
• Other financial losses tied to the defect, such as the loss of use of your vehicle

To build a strong GM transmission case, you’ll want to gather:

• Service and repair invoices
• Vehicle purchase or lease agreements
• Warranty claims or communications with GM dealerships
• Records of out-of-pocket expenses (towing, rentals, etc.)
• Notes on how the defect affected your daily use of the vehicle
