A newly issued customer satisfaction program offers a fix for certain 2024 Buick Encore GX and 2024 Buick Enclave units that GM has determined may be affected by a transmission fluid leak, resulting from a transmission case defect.
Vehicles from the Cadillac, Chevrolet, and GMC brands are also included in the program alongside the Buick Encore GX and Buick Enclave, as GM has instituted a far-reaching implementation of the free fix to prevent future problems for its customers.
Customer Satisfaction Programs number N232433891 and number N232433890 are running in parallel for Buick Encore GX and Buick Enclave vehicles configured with front-wheel drive (RPO code FWD) and for all-wheel drive (RPO code F48) Enclave units respectively. The total number of vehicles affected by the issue is unclear, though GM has provided VIN lists to dealerships.
Transmission fluid can potentially leak out through a porous area near one of the transmission case mounting bolts, according to the customer satisfaction program announcement. This could eventually lead to inadequate fluid levels inside the case.
The fix, which is offered completely free of charge through June 30th, 2026, is carried out by removing the current transmission case and replacing it with a new case. The program underlines the fact that dealers must apply the fix immediately when an affected Buick Encore GX or Buick Enclave arrives at their dealership, whether for repairs or as part of the dealership inventory.
Notification letters are on their way to owners of record from GM itself. These letters will be sent to owners in the U.S. and Canada by General Motors. For exported Buick vehicles, it is the responsibility of local dealerships to mail notification letters to owners of record for that region.
As a reminder, the Buick Encore GX is motivated by two powerplant options, the turbocharged 1.2L I3 LIH gasoline engine developing 137 horsepower and 162 pound-feet of torque, and the turbocharged 1.3L I3 L3T gasoline engine developing 155 horsepower and 174 pound-feet of torque.
Meanwhile, the Enclave is powered by the naturally aspirated 3.6L V6 LFY gasoline engine, which produces 310 horsepower and 266 pound-feet of torque. Both vehicles use the GM nine-speed automatic transmission for cog swaps.

” a porous area” … you mean like a “crack”?
Like the 2.7 engine blocks? … like it’s getting to be a habit ?
Another problem starting to show up with both the 1.2 / 1.3 later engines is the oil pans that are made of plastic will crack if the drain plug is over tightened. I’d settled in on the decision to buy a ’25 Trax LT … now having second thoughts.
And they tell you you can take the TrailBlazer off road.
Wonder what a high rock can do to a plastic oil pan?
You can’t make this stuff up.
Buick products seem to be cheaply made. So, you are basically paying Buick prices for a Chevy.
What about the Sister vehicle? The Chevrolet Trailblazer.
Chris we will be reading this same story sometime this week for the trailblazer. Is this true/plastic oil pan. U don’t have to be off road, just running the highways in summer with tractor trailers leaving behind there retread carcass remains and trying to dodge them. This would be all it takes for a plastic oil pan.
I have no idea. As my 24 Trailblazer AWD has 2000 Miles. There is a Plastic Shield underneath the engine bay
