NHTSA Complaint #11695459 — 2021 CHEVROLET TAHOE

My 2021 Chevrolet Tahoe recently displayed a warning message that said “Service Transmission – May Not Be Able to Shift Soon.” The message appeared at approximately 132,754 miles. Since then, I’ve noticed delayed and rough shifting between gears. The vehicle still drives and shifts into gear, but the message and behavior are concerning. I have an appointment scheduled for a diagnostic inspection on Tuesday, which was the earliest available. I have not yet received a confirmed diagnosis, but I’ve seen that many other 2021 Tahoe's and similar GM vehicles have experienced the same transmission problem and were included in recalls. My vehicle’s symptoms match those reports, though my VIN was not included. This situation makes me nervous because I drive with my four children daily. Even though the vehicle hasn’t completely lost the ability to shift, a sudden failure while driving could put my family and others on the road at risk. The warning itself suggests a potential failure is coming soon. The vehicle has been properly maintained and has not had prior transmission work. I’m reporting this because it appears to be part of a larger pattern that should be investigated to determine if more vehicles need to be included in GM’s existing transmission recall.
