I had an appointment scheduled for Monday, and I wouldn't have bothered going if there wasn't a real problem. Instead of actually listening and helping, they talked to me like I was clueless -- super dismissive. The GM technician's explanation and the service advisor Viktor was the worst part. I highly doubt the test was conducted on Heavy traffic stop and go. It felt like they were just making excuses and not taking my concern seriously at all. I left feeling frustrated, disrespected, and completely let down.
Definitely not what you expect after spending this much money on a car.
there are a few concerning issues with the tech's response
1. The tech is suggesting driving technique is causing the issue by claiming you're "dragging the brake" in traffic. This is a common deflection tactic when they can't diagnose a problem.
2. The statement "vehicle not equipped with automatic transmission has dual clutch transmission" is misleading. The DCT is technically an automatic transmission (you don't manually shift with a clutch pedal), just a specific type.
3. The "could not duplicate concern" after only 18 miles of testing is inadequate, especially since DCT issues often appear intermittently or in specific conditions (like the stop-and-go traffic you mentioned) again HEAVY TRAFFIC not hauling ass at the back roads and light traffic
4. I'm causing excessive heat to the dual clutch. What this means: The dealership is essentially blaming my driving technique rather than acknowledging a potential mechanical issue. how should you drive in a HEAVY TRAFFIC SITUATION STOP AND GO ? should I just step on the brakes wait like 5 car length to go ? You guys ever driven or live in LA ? sounds really dumb
The "must fully release brake pedal from a stop" advice is reasonable for DCT operation, but significant shuddering is NOT normal behavior for a properly functioning C8 transmission, regardless of driving technique
