Some 2024 GMC Acadia owners may need a new torque converter, per a recent GM service bulletin. According to the bulletin, the issue may trigger a “Service Engine Soon” (SES) light, as well as diagnostic trouble code (DTC) P2817, indicating a potential problem with the transmission’s turbine shaft seal. The issue could potentially affect all configurations of the 2024 GMC Acadia, as well as the 2024 Chevy Traverse and 2025 Buick Enclave.
The issue was also documented by the National Highway Traffic Safety Administration (NHTSA) under ID Number 11009052, and affects models equipped with the GM eight-speed automatic transmission.
According to the bulletin, the turbine shaft seal, which seals the torque converter, can sustain damage during the installation process, resulting in error code P2817.
In order to address this issue, GM dealers are instructed to remove the transmission and the torque converter in order to access and replace the damaged turbine shaft seal. GM has updated the seal design from a traditional O-ring to a Z-cut square Teflon. Both the torque converter and the seal will be replaced during the repair process​.
Those 2024 GMC Acadia owners affected by this issue are encouraged to mention bulletin PIP6005 when consulting with their dealership and scheduling repairs. Service work for this specific problem may be covered under GM’s Powertrain warranty, so check with your dealer regarding coverage details before proceeding with any work.
As a reminder, the 2024 GMC Acadia debuts the crossover’s all-new third generation, bringing with it new styling, larger exterior dimensions, additional interior room, and new tech features, as well as the new turbocharged 2.5L I4 LK0 gasoline engine. Engine output is rated at 328 horsepower and 326 pound-feet of torque.
The 2024 GMC Acadia rides on the GM C1 platform, while production takes place at the GM Lansing Delta Township plant in Michigan.

Killing the V6 and the proven 9 speed was a mistake
I had the more than adequate 6-speed in three Noxs. Zero issues.
The No. 1 Engineering Rule GM LOVES to break: “If it ain’t broke, don’t ‘fix it’ .”
Didn’t we go through this recall in the 2017-18 models?
While they’re taking care of the recall why not replace that sewing machine 4 banger?
None of these should have a 4 cylinder in it no way…crazy stuff!
They also had issues and recalls with the previous 9 speed automatic that went into the 2018/2019 variants
Being the owner of a 2018 Acadia Denali with 95,000 miles…No issues.
I’ll keep driving it as long as it keeps going. GMC lost Me by putting a 4 cylinder in the new Acadia which is a good looking ride…but I’ll be buying another brand with a V6 in it.
