BREAKING: GM is officially recalling the L87

[headwest]

I think we got this.

They said this without me telling them my VIN. Unless they pulled it up by my phone number..hmm.. I guess I'll wait for my second GM letter at this point

Maybe they're doing them for regular customers, like if you don't have history with them or they don't know who you are.

Doubt it. I waited a year for the airbag recall. GM released the recall in batches as dealers would have been overwhelmed otherwise. I am sure they are doing the same here. GM will determine when you are eligible for the recall via the second letter.

For those that have been to dealer for the test how long was the vehicle at the dealership. I still haven't received my 2nd letter yet but had to stop by the dealer for another issue, ask the SA some questions and about how they needed the vehicle. He indicated that it was taking 2 to 3 days for the testing to be completed. He also indicated he could tell when people received their 2nd letter because they get slammed for appoinments.

 

[KMeloney]

Does the second letter refer to only the dealership that sold you your truck? Or does it let you know when your local dealership is ready to do the testing? I'm assuming the former, but...

I bought my Yukon out-of-state (at a dealership that's @40 minutes away). I've been going to a local dealership for oil changes, etc. I'd prefer to have the testing done at my local dealership -- but I suppose I won't know when they're ready to do the testing unless I proactively call them, assuming the second letter tells me only when my original dealership is ready.

Who got what?

 

[headwest]

Seems we've run the gamut on this. I have a vehicle pending also. I got my first letter and waiting on the second. Dealer says my number has not come up yet. Seems all we can do is read what GM is stating and speak to dealer. As stated before GM is triaging this. Meanwhile I guess we just drive until we get the second letter or engine fails. It seems most will pass for what is worth.

I don't see how it could possibly take 2-3 days for testing to be completed. Maybe the dealership could let it sit for 2-3 days before they get around to it, but the inspection procedure itself should take about an hour. There is a video posted of the actual inspection procedure, and this document specifically states 0.9 hours of labor time for the inspection (Labor Operation 9107931). Now, I'm sure the first few times an individual technician does it, it could take a little longer until they get the hang of it, but not 2-3 days to perform one inspection.

EDIT: Also note that the 0.9 hours is inclusive of doing the oil change to 0W-40 oil assuming the engine passes, so the inspection time is technically even less than an hour.

I may be 100% wrong on this, because I haven't received my second letter yet, but I was assuming that the letter is not dealer-specific. Instead, it just means that GM as a whole has opened up your VIN for inspection (regardless of what dealer you choose to take it to). I am assuming that the second letter looks more or less like this, and won't guide you/limit you to any specific dealer, but hopefully someone else can chime in:

Early on, some dealerships were prepared (with the oil, caps, and procedure) to do the testing, and others weren't. And from what [I think] I've read here, if a dealership was ready to do the testing, but you hadn't received your second letter, they'd do the test for you. Now, maybe ALL dealerships are prepared to do the testing at this point; but if not, then getting the testing go-ahead via a second letter -- only to find that your local dealership(s) aren't prepared to do it -- seems pretty silly, potentially.

Maybe I didn't read that some folks had the test done without a second letter... Is a dealership supposed to deny you the test if you can't produce the second letter?

I don't think you have to be able to produce the second letter, but I think your VIN has to have been "released" by GM (which is maybe essentially the same thing as getting the second letter, i.e., they happen at about the same time). So, no I'm not aware of anyone who has had the test done prior to their VIN being released by GM. I didn't intend to suggest that was the case.

I am assuming that most, if not all, dealerships are prepared to do the inspection by now, but who knows. I guess I was thinking, if you get the second letter from GM, and then you call your preferred dealer to make an appointment, and for some reason they can't do it (don't have the PicoScope, don't have the oil, all booked up, whatever), then you could just keep calling other GM dealers to find one who can do it - if you have other options nearby, but I realize not everyone does.

I took mine in at 10am and got it back by 3pm. The recall process overall was maybe 2hrs. The surprise for me was that if it *fails* they said they couldn't release my rig back till they replace the failed parts (a.k.a. engine) unless maybe I signed away some rights. So maybe ask what they will do if it fails - e.g. loaner? rental? how long? - until it's fixed before handing over they Fob

In my case the rig runs perfectly OK with 63K miles so I wasn't expecting any issues and it passed / recall completed.

 

[Scarey]

We still have not heard first hand of someone failing the pico test and getting a new engine. I think everybody gets a pass.

 

[headwest]

Yes, some have been replaced. This is from a FB thread dated May 16. Also note this was a 2025 engine.

6.2 engine replacement update - Dealer called me Monday and said the engine came in and they installed it in two days. The service manager said it’s been a nightmare for them and engines just randomly show up with no notice. Picked it up yesterday which was exactly one month to the day since it failed even though they told me it would be 4-5 months. Final cause is that it spun two bearings in cylinders 3-4. They said they have done dozens of 6.2 replacements recently and are in the process of testing recalls with some vibration tool in the engine. Haven’t heard of that being the process but I didn’t bother asking any more questions, just got in my truck and drove it home. Also confirmed it was an engine made in 2025

Thanks for the reply's, it seems my closest dealer is just guessing at the time, glad I now know the labor time from GM,

Can't tell (from that) whether the poster was saying that his original engine was made in '25, or his replacement engine was made in '25.

Assuming here that you're replying to @Scarey having said that we haven't seen someone FAIL THE TEST and get an engine replaced as a result, your FB cut-and-paste doesn't disprove what he wrote. The FB poster admits to not even having heard anything about the Pico test (and his engine crapped out on him a month ago). So, his truck was at the dealership for a month, waiting for an engine he was told would be 4-5 months out. He's getting his engine replaced as a result of the engine having failed already -- not because it failed the Pico test.

 

[headwest]

Understand. I had

Understand. I didn't want to copy the entire FB thread as some of it was not relevant. I had been searching for this matter off and on and there are some FB threads on GMC. A local dealer a month ago told me they had 10 new engines in stock and he didn't know how many they had replaced. I didn't pursue model year but assumption at the time was the recalled engines, not '25s.

So from sources I can't recall, having searched over time it seems that yes they are replacing some of the recalled engines and mentions of some of these being in the '25 vehicles. Now when they were exactly produced I couldn't say. Yes, his engine failed prior to the Pico test and the reason dealers now using that on said models before they fail. Maybe I misunderstood your points.

 

[KMeloney]

Maybe I misunderstood your points.

@Scarey was saying that he hasn't seen where anyone failed the Pico test and got a replacement engine out of it (only heavier oil), insinuating that he thinks the whole Pico test is BS and that everyone magically passes it... Then, you appeared to refute that, posting a FB post where someone DID get his engine replaced -- but he clearly didn't get his engine replaced on account of failing a Pico test.

Yes, people are getting engines replaced, but probably only because their engine crapped out, they've been waiting, and GM is now finally producing more 6.2 replacement engines. Otherwise, I have to agree with @Scarey and his belief that we haven't seen any accounts of anyone failing the Pico test and being told they're getting a whole new engine.

I just called the service manager who I've gotten to know where I've had my truck serviced and asked him how many vehicles he's had that failed the Pico test and had to be replaced. He's had two since the recall. The remainder have passed. It's taken about a month to get those engines replaced.

That dealer is a fairly large dealer so it seems there are not a lot of failed Pico tests but they do happen. Would be nice know industry wide how prevalent. GM says about a 3% failure rate but that leaves a lot of questions. The service manager said the recall will go on for years due to the 800,000 engines out there.
