GM Transmission Problems

General Motors equipped many of its’ models (see below) with 8-speed and ten-speed transmissions. Owners of these vehicles have experienced transmission problems such as hard shifting, shuddering, hesitation, gear shifting problems, leaks and loss of power. Through the years, GM has issued 13 versions of technical service bulletins related to the shifting alone. There are reports that GM has known about the defect for years and that internal company documents indicate that GM acknowledges that the defective transmissions present a safety defect. Further, GM directed their dealers to tell their customers that harsh shifts were “normal” or “characteristic”. Reports indicate that this defect cannot be repaired, and that GM hopes to cure the transmission defects with a redesign in 2023.

Under state and federal warranty laws, a consumer has a right to be compensated for a vehicle that possesses manufacturing defects that render the vehicle useless or so inconvenient, a reasonable person would not have purchased the vehicle had they known of the defect at the time of sale.

Implied Warranty Of Merchantability

Implied warranties are unspoken, unwritten promises, created by state law, that go from the manufacturer to their customers. In common law states, implied warranties are based upon the common law principle of “fair value for money spent.”

The implied warranty of merchantability is a manufacturer’s basic promise that the goods sold will do what they are supposed to do and that there is nothing significantly wrong with them. In other words, it is an implied promise that the goods are fit to be sold. The law says that manufacturers make this promise automatically every time they sell a product they are in business to sell. For example, when you purchase a brand new vehicle, the manufacturer is promising that it does not have defects and operates on the road as expected and intended. If the vehicle jerks and, shudders, stalls or in any manner renders it unsafe or unfit to drive, then the vehicle is not fit for sale as a vehicle, and the implied warranty of merchantability would be breached. In such a case, the law requires the manufacturer to provide a remedy, including compensation for the difference between the vehicle purchased and the vehicle’s diminished value due to the defect.

    • I have heard of the lemon law before but never fully understood what it actually meant. I saw an add on Facebook for the Duck Law Firm Lemon Lawyer. I decided to reach out to them & I’m glad I did! I was a little skeptical at first because it seemed to good to be true. I literally replied to a few emails scanned some documents and maybe made 2 phone calls during the entire process. Of course I had questions, how does this work? Will I really get paid if there is a winnable case? I explained to them that I had a 2020 GMC Sierra with multiple/recalls including safety recalls & that my transmission had to be pulled due to failed transmission pump part. My vehicle was only 1.5 years old w/28K miles, which is well under factor warranty of 3yrs/36K miles. The Duck Law firm asked me to send all service receipts. After I submitted the receipts a few weeks went by & The Duck Law firm confirmed I had a winnable case & there would be no service charge for this work that was already completed. No harm no foul, it was that easy. In about 9 months The Duck Law Firm reached a settlement with GM and I received a substantial settlement for my truck. It was that easy. The Duck Law firm is very professional . If you have a lemon of a vehicle do not hesitate & reach out to them ASAP.

    • I am so pleased with Duck Law Firm and how they handled my case. They were very responsive and I couldn't have asked for better service in dealing with the issues I was having with the dealership. Kevin and his team were very upfront with me about everything from the get go and told me exactly how things would proceed and how long the process would take. This was the first time I have ever had to deal with something like this, and I hope I don't have to go through this again, but if I do, I would call them back in a second. Many thanks to Kevin and his team for making me feel respected, heard and understood.
