The contact stated that her husbands air bag did not deploy. Medical attention was needed, and the contact's husband was transported to the hospital, where he succumbed to his injuries. A police report was taken. The vehicle was towed to the tow lot, where it was deemed a total loss. The contact stated that there were no additional injuries. The manufacturer was not yet notified of the incident. The failure mileage was unknown.
The turbo boost failed cylinder 2 ( after being repaired ) continues to show issues
I am experiencing recurring transmission and drivability issues with my 2016 Cadillac CT6. 1.Rough Shifting: When shifting from park to reverse, the transmission shifts roughly, causing a noticeable jolt throughout the vehicle. 2.Fluid Leakage: I have observed fluid leaking from underneath the car when parked in my driveway. However, the leak is inconsistent - it disappears for a few days after rain or washing my driveway but then reappears under similar conditions. 3.Delayed Shifting: When accelerating from a...

stoplight, there is a delay before the transmission engages, causing hesitation before the car moves forward. 4.Automatic Start-Stop Issue: The vehicle has an automatic engine shut-off feature that activates when stopping at a light. When I take my foot off the brake, the engine restarts abruptly, causing a harsh jerk that shakes the entire car. This makes it feel like the transmission or another component is not engaging smoothly. 5.Check Engine Light Issue: The check engine light came on for a day, but before I could take it to a repair facility, it turned off on its own. Because of this, I was unable to retrieve any diagnostic codes. I am concerned these issues indicate a faulty transmission system or related defect that may worsen over time. I request an investigation into whether this is a common defect in the 2016 Cadillac CT6 and if any recalls or manufacturer repairs are available.
The car keep losing power pressure when driving it's jerk when put into gear

back to Waldorf Cadillac & Chevrolet to have to vehicle repaired. The vehicle is doing the same thing it was doing , when the vehicle was previously in the Repair Shop. The Technician informed me that Cadillac recommend the fluid in the transmission be changed to a high-performance fluid. This recommendation was issued to the dealers several months ago. Now the dealer is charging me approximately $1,000.00 for Transmission Fluid. I asked the Technician why the problem wasn't corrected while previously in the shop. No reply. If Cadillac knows this is the problem, why is the customer being charged for this service, if this will correct the problem. There is 64,000 miles on my vehicle.
Vehicle has sudden violent forward Jerking motion at stops, delayed performance when accelerating ,hard shifting when changing gears, clunking noise when shifting into low gear
Vehicle involved in a severe accident, airbags did not deploy. The vehicle was in motion on a hwy. Vehicle was struck by oncoming traffic and then launched into a ditch. None of the airbags deployed during the incident.
When I am turning under 25 mph, I accelerate and there is a delay and a drag before the vehicle starts to accelerate. If I do not allow room, I could get hit because there is a delay. Very dangerous. Almost feels like a vacuum issue.
Car will not respond for at least 2 seconds during a slow, rolling stop, when trying to accelerate again. Unable to perform evasive manuever, if needed, secondary to the delay to accelerator input. Harsh 2-1 downshifts also at slow speeds and can even feel as though you were struck from behind. Highway driving is excellent; city driving challenging with the transmission. The driver has to learn how to drive this vehicle. Find it very unusual after owning 5 other cadillacs and never had this problem. I bought this...

I had the transmission re-flashed, which provided perhaps a 1-2 days relief. I will continnue to persue with dealer, but wanted you guys to be aware. Cadillac should fix the problem; new/different type of transmission or re-work the 8l45/8l90's with differnet vlaves/software or buy it back from me.
