In 2019, GM released service bulletin 18-NA-358 that confirms the company’s knowledge of of defective parts in transmissions. I have a 2017 Cadillac XTS experiencing these symptoms and GM should be responsible for parts failing due to metal shavings. This needs to be a recall. The transmissions are not getting gas, shuddering, and stalling when accelerating. This shuddering has almost caused me to be in many accidents. The vehicle owner should not be responsible for replacing expensive parts and entire transmissions due to metal shavings stalling transmissions.
