2024 Chevrolet Trailblazer Engine Problems

My 2024 trailblazer lt's engine light came on about a month ago. I took it to a local dealership and they said it was caused by CCND. Diagnosed code P0128 in pass/fail status. They test drove it to get light to come on and it was unable to duplicate it. They cleared the codes. A month later it came back on. I took it to my dealership and they said they have to take the entire front end off to replace the engine coolant bypass valve. They said that the electronic component was going bad. This car isn't even 2 yrs old. This should not be happening.

My 2024 Chevrolet Trailblazer ACTIV with 26,000 experienced complete engine failure while driving. Palm Chevrolet said my Trailblazer had “internal engine failure” and needs to be replaced.

While in traffic, brand new 2024 Chevy Trailblazer vehicle has stalled on us a few times now and doesn't start right back up. It appears to happen when the vehicle is going from the fuel saving "start-stop mode" and we've found ourselves in a precarious situtations in traffic. I can foresee this happening at a very dangerous time causing a bad wreck. We just dropped the vehicle off with the dealer as we've had other issues with safety deterrent system going off for no reason and other pop ups on the instrument panel. However, the stalling in the middle of traffic is my worst concern.
