Reply To: 2023 Tahoe bad injector

I also had a bad injector. 3rd cylinder. what cylinders were impacted in your Tahoe? I took one of the first deliveries of my 2023 in October. Injector went at about 2K miles. They were able to find an injector in a couple of days at the beginning of January 2023. Dealer said he got it from a GM warehouse in Michigan. GM paid for a rental. Sounds like a common problem like they had with the 2021 valve lifters. If so may be a design flaw or a bad batch of injectors. Also had a one time problem of the Tahoe automatically shifting to neutral at a low speed. Had to shut the motor off and restart. When I got home and turned off the motor a message was displayed that an update had been downloaded and ready to install. Took 1 hr for the update and the Tahoe was locked out of service. I changed the download setting to update in the background and have not had the problem again.
