2023 Tahoe - Bad Injectors - 4900 Miles

[ChrisA]

I am sure some of you are aware of this potential issue so wanting to see if anyone has any real insight into the issue?

Currently my 2023 Tahoe has been sitting at the dealership since April 1st having to be towed in at 4900 miles with what is being diagnosed as bad injectors and that it is not driveable until they are replaced. So here we are 13 days in Tahoe has not been repaired and I am told by GM Customer Care that they cannot escalate the case or parts team until the 19th of April.

Anyone hear of these issues? Dealer said he has 2 other 2023 Tahoes sitting waiting for repair parts too - sitting here wondering if I should dump the Tahoe after it is repaired and move on. Pretty loyal GM owner here having purchased 9 GM cars, trucks and SUV since 2016.....

I would be surprised if its injectors. Likely something more serious, but in either case you are in a waiting game for parts..

If you are really concerned about the reliability of the truck, check on your states lemon laws, or wait until its fixed, and dump it.

I cant give you any real advice on what to do, or not do, as I am extremely biased on all NEW GM products.

There was a change to the injectors for '23 and you're not the first person to have failed injectors... see link below.

2023 Tahoe LT Lemon

First time Tahoe owner (GM for that matter) and recently purchased a 2023 Tahoe LT brand new (first new car purchase). At about 300 miles I randomly got multiple errors and flashing check engine light with engine running rough(photos and error codes from OnStar diagnostic). Traction control...

Had this happen to me when out of town last month. 23 Tahoe. Had to stay the night and take to dealership next day. Bad injector bank 5. 7400 miles. Took two weeks for replacement parts. Received rental that was covered by Chevy under warranty.

Same thing happened again yesterday. Back in dealership. However it started with codes: U0146, P050D, U152B, U0146, U0566. All codes came up when dealership checked it in. Now they saw it's all related to bad injectors.
bank 1 and 7 now having to be replaced. 8600 miles. Was told they are back ordered and it could be several weeks.

I have already contacted a lemon law lawyer and I know now I have options being in California.
Extremely frustrated as this is my 1st Chevy I purchased.

So you are gonna lemon a ride when it’s diagnosed, and just waiting on parts?

It's not a good situation. Currently sitting still waiting on parts, really no clue from GM on what and when they can fix it. I am going to keep pushing them to get it fixed ASAP, then it will be a decision on me to keep it, sell it or trade it in on something different. I have purchased over 10 new GM vehicles since 2016 and this might potentially be my last - I am sure other manufacturers have their issues too but the lack of response from GM on what appears to be a known issue is disturbing.

As stated GM Customer Care was basically useless as they are reading from a standard script and playing a game with people vs. telling them the real story. I plan to be a big pain in their side this week till I get some answers and movement - sitting at the dealership since April 1 and no real news or anything from them except that they have to wait to escalate - that is crazy

The value of my 2005 Z71 just keeps climbing.

Once that ride is out of service for 30 or more days CHA CHING!!!!!! The lemon law kicks in at most states. Hire a lemon law lawyer and do a cash and keep deal along with a free massive GMPP warranty.

Replaced injector #8 on a 22 Silverado with 16k miles at work today. So it is a possibility.

Can you tell me how involved this is? Sounds like you might work at a dealership service department - is this an easy repair? If this was your brand new vehicle would you have it repaired and move on and not worry or have it repaired and move on to something else?

 

[ChrisA]

Update - after opening a case last week and then escalating the case yesterday with my intentions that if it sits for 30 days I will be looking for buy-back potentially or lemon law - shocking the parts were overnighted and arrived at dealer today and the repair is done and we are back on the road after 18 days.

Injector #2 was stuck open and was replaced along with seat blower replacement recall and DRL recall - so the moral of the story is if you don't want to wait in line keep pressing GM with opening a case and escalate, escalate all while be nice along the way. The dealership was great as they were at the parts mercy and they completed the repair the morning the parts arrived - kudos to them....

I’m curious as to your options as I too live in. CA. Also makes me nervous because our 23 Yukon will be here in a few weeks

This same thing happened to my 2023 at 700 miles Back in December. Dealer originally said the injectors were back ordered but all of the sudden they were able to get one shipped from GM in a few days. Maybe because it was such low mileage I got prioritized. I was reading this problem happening to others on this forum as well

I have a 2022 that has been at the dealership since mother's day. they said they think it's the fuel pump control module. That being said I felt like when they called that they wasn't sure what was wrong with it. It will not start just turns over no start . I only have 5200 miles on it . It turned one on 5/1 . We have not heard a word since last Monday when they give me a loaner.

Under warranty, correct?

I wouldn’t call the fuel pump control module, a “common” problem, but there’s been at least another ~5 forum members that have reported the exact same problem and the module was the root cause.

Yes it is but as of yesterday they still have not got the parts. I really don't think they know what's wrong with it .

Well, sounds like they have a pretty good suspicion, if they are waiting on parts...they have an idea of what they want to replace.

2023 Yukon had 10 months at 7500 miles, started spitting and sputtering yesterday and all the check engine lights came on. It’s a bad fuel injector #8 and thankfully the part is in stock. Didn’t know this but if you push the blue OnStar button, they can run a full diagnostics and if you push the blue OnStar button under warranty, they can give you a free tow. Good to know and hope I never need it again.
