There are 2 owner-reported powertrain & transmission complaints for the 2017 Cadillac XTSin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
XT5 HAS A TRANSMISSION SHUDDER, BETWEEN 16MPH AND 50MPH, WITH THE AISIN AF50-8 TRANSMISSION. GM REPORTS NO PROBLEM WITH THE AISIN. CADILLAC TECHNICIAN DROVE VEHICLE AND DID NOTICE SHUDDER. NEXT STEP, INVOLVE GM ENGINEER. IF HE DOESN'T FIND AN ISSUE, I HAVE TO LIVE WITH THE SHUDDER.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
