New vehicle with engine light on already

[amarillo71]

I have a 2025 Equinox that has nasty over 6000 miles on it. Last week the check engine light came on, and the phone app says it is an issue with the throttle. I took it to the dealer Tuesday who said it was a faulty fuel injector #3. They didn't have one in stock, so they gave me a loaner and ordered the part. I picked up the vehicle yesterday with no issues. This morning, engine light came back on with the same error message. I called the dealer and have another appointment next week to bring it back in. They are going to replace all of the fuel injectors this time. It's this some kind of known issue? I just think it is insane at 6k miles with the same issue twice already. Wondering if I got a lemon...

Lol had just over 6000 miles... didn't proof read...

It stinks to have problems with a new car. Injectors sound more like fuel management than throttle control? A bad batch of injectors is probably possible. Hope they get it figured out for you quickly.

That is a bummer for sure. Were you able to get the actual OBDII codes?

I don't have a lot of faith in dealer service. They don't typically have the resources to troubleshoot. They follow a matrix and swap parts.

P050d, and other various codes because of a hyperactive drivers side mirror, see screenshot.

The reason I asked is I suspected it was going to be the P050D code. This is the "rough idle after cold start" code. Some people on this site are dealing with it. This code seems to effecting 2024-25 model Equinox, Traverse and clones and GM hasn't come up with a fix yet. It appears GM added this code to the logic around 2024 on their 4cyl turbo models and it's causing grief for a lot of owners.

I'm not sure why they messed with injector #3 for the P050D code, but maybe something solid led them in that direction.
