CT5-V 2025 CT5 Blackwings - have your dealer check oil plug on the front of the engine (Service Bulletin attached)

Great Guess I'll be checking my '24!

So my soon to be 5BW was built second week of January this year. My plug was actually pressed in all the way from the factory. Here is the picture the technician took upon their inspection.

Looks like they added a quality check for it on the line based on the markings.

I've been super busy at work and haven't had time to properly document the issue I encountered in a new thread, yet.

For those of us lucky to have a 2025 CT5 Blackwing - there is a service bulletin posted today for ALL 2025 CT5 Blackwings to have the oil pan checked for a possible manufacturing defect. This document was shared with me this morning and my car has had the 'fix' completed. Still working with Cadillac service escalation team to hash out compensation, etc.

Have noticed oil low on dipstick 2x.. thought it was my driving habits ! Thanks for the bulletin

Well It happened to me, took car out for a quick spin before going on vacation last week and low oil pressure light came on. Pull over right away, pushed car backwards and saw a big puddle of oil. Never received any sort of notification about a recall or bulletin. SA told me it was the oil pan drain plug, which they didn't have in stock. I'm sure it was the pickup plug. Set to pick up the car day after Memorial Day, I will have them put it in the air to see how much of a mess it is underneath. I also am in PHX AZ. My car was completed on 10/30/24 and delivered in early January '25. Anyone else get any compensation? Eligible to be turned back in?

That sucks. I guess we have bad luck here in AZ. The only compensation I received was a Cadillac gift box with crap in it and then they gave me 70,000 rewards points. I tried to get extended warranty but no luck.
I almost have 1000 miles on it after it happened and there seems to be no other issues. Im taking it in once I hit 1500 to have them do an oil change and check to make sure the oil is clean and also have them make sure it doesn't need more cleaning underneath.
Now I just got a message this morning saying " Service Brake assist" so will have to have them check that out also now.

Sorry it happened, Mike.

I am curious, by "eligible to be turned back in", are you asking if Cadillac should take your car back and refund your money? On what basis? A part failed, and they will fix it at no cost to you. Why should they take back a 4 month old used car? Apologies if I am misunderstanding your question.

I don't think you'll get anywhere with GM taking the car back...unless your local dealer has a way they can flip it for profit which I doubt.

GM is considering this a "Customer Satisfaction TSB" and NOT a recall. It SHOULD be a recall but based on my own observation, they will not recall it unless someone gets hurt and reports the accident to the NHTSA. It took them 3 years to own up to 700k 6.2L truck engines being defective and it was the NHTSA that ultimately forced them to do it due to car accidents with engines grenading themselves at high speed.

I'd get the car on the lift, make sure oil has been cleaned off in engine bay (there is a plastic tray right under that plug) as well as make sure none of it made its way back on the under carriage or hit the tires.

If you are reading this and your car was produced between August and December 2024 and you have not had this TSB done, you should absolutely schedule it ASAP as it seems to be only a matter of "when" and not "if."

GM Authority just put out a story with some details but omits the timeframe for when the included cars were built. I think CB34 has it right in that it is 2025 models built in calendar year 2024. But would be nice if the story had confirmation.

This thread is more informative than that article. I tried to link to it in the comments but they deleted it.

It is actually a recall now, at least that is what my SA has told me.

Sorry Mike. It does suck. Happened to me as well. I pushed them for 100,000 GM bucks towards future service. They offered much less and I told them that due to the oil leak the tires were exposed and sat with oil on them at the dealer while the new oil pan was on BO so they at least need to give me enough for two new rear tires, they came back and gave 100.000 and at that point I was tired of negotiating. I also tried for extended powertrain coverage but they wouldn’t budge on it. I’m at 1,300 miles now since and no issues. Had the oil changed at 800 (600 post plug issue) and it looked good.
Got full PPF and she’s back purrring nicely now. Hope the same for you too man.
