My name is Jessica Anvar, and I am a California Lemon Law attorney committed to helping drivers escape the “Professional Grade” headaches of a defective vehicle.
GMC is built on a brand identity of rugged durability, but in recent years, many owners have found that “built like a truck” doesn’t always mean “built to last.”
From the high-tech hurdles of the Hummer EV to the notorious “Chevy Shake” and transmission failures in the Sierra and Yukon, facing General Motors (GM) requires a legal advocate who understands the specific mechanical DNA of these heavy-duty machines.
I have curated a list of the top California Lemon Law experts (excluding myself) who specialize in holding GM accountable, ensuring that California drivers get the buybacks and justice they are legally entitled to.

GMC Lemon Law FAQs
- Does a recall count toward my Lemon Law case? Yes. If GMC issues a recall for your Sierra or Yukon and the dealer cannot provide a permanent fix within a reasonable timeframe, it strengthens your claim.
- What if I use my truck for work? In California, the Lemon Law covers small business vehicles as long as they weigh under 10,000 lbs and the business has five or fewer vehicles registered.
- How much does a GMC Lemon Law Attorney cost? Nothing. Under the “Fee-Shifting” provision, GM pays the attorney. If you don’t win, you don’t pay.
