OIL COOLER LINES - Check yours now! Urgent 2019 owners

[romeactual]

I posted about this previously and had a decent outcome with reimbursement, wanted to share all the info I can. Looking through the forums, it appears its continuing to happen to more people! I would advise 2019 guys to check your oil cooler lines IMMEDIATELY! Mine is a 2019 GMC Sierra 1500 SLT

 

I noticed a small leak in driveway after some real cold temps in Michigan. Took skid plates off and noticed the oil cooler lines were leaking on all four connections between the rubber hoses and metal crimps. It appears cold weather exaggerates this issue.

 

Worst case scenario is those crimps fail, and you lose all of your oil while on the road. Catch it before that happens, and out of warranty or maybe even in warranty, you're stuck with a ~$750 to $1,200 service fee at a STEALERSHIP, just to replace the oil cooler lines (a ~$150 part). It's not an easy DIY job, hence why I paid.

 

I got quotes at different dealerships for this service. First one was over $1200 at an actual GMC dealership, second one was around $750. I went with the cheaper which was solely a Chevy dealer.

Of course, there is no warranty for this and although their is a TSB for this issue, its only applicable as of now to about 500 trucks. If your truck is in that group, this procedure would be completely FREE. GMC TSB N192220080 - Please reads this through and you will see that GM is acknowledging this is an issue, but for select trucks only.

 

WE NEED THEM TO ACKNOWLEDGE THAT THIS IS HAPPENING TO WAY MORE TRUCKS.

 

I called GM customer service to set up a "case" with them, and have been waiting the last few weeks on cash reimbursement. They have already given me $500 worth in GM rewards to use at a dealership, and they are currently in process of reimbursing me cash for the service. I have an email which states they are reimbursing half the amount for parts and labor.  This situation may be unique for others, but get a claim established AFTER paying for the service. You might just get a refund! You cannot setup a claim before the service.

How is this not covered under the powertrain warranty, which iirc is 5 year/60,000 miles?  Is the powertrain warranty the reason you're obtaining financial reimbursement?

This has been a problem as long as they have been using oil cooler lines with the crimped hoses. The chances that the hoses can become detached from the metal lines is almost non-existent except maybe in those 500 trucks. My 98 is on its third set so the replacements are not any better than the originals. A more permanent solution may be to cut the crimps off and double clamp the hoses or have a hydraulics shop make some up for you

Reading around and talking to the service dept, there are def some stories of them becoming completely detached. That is why I am trying to bring awareness to this situation. Based on all 4 connections leaking at the same time on mine, I would assume it would be more likely to detach. Both dealerships recommended I don't drive the truck at all until it was fixed due to possibility of them failing. Yes, you could be right about them not failing, but this isn't something I would risk if they are leaking, get them replaced or as you said, cut the crimp and double clamp the hoses.

I'm at 70k miles but also hoses (oil cooler lines) are not covered under power train. Chances of getting a "Good Will" repair are higher if you are in the power train warranty though. My biggest gripe is that this shouldn't be a wear item at this mileage, it is a commonly known defect on a part that goes bad prematurely. It has happened on trucks that are half the miles. It needs to be revamped, the design is flawed.

Oil Cooler lines are covered under powertrain warranty, specifically so if I remember correctly.

Yep, my 2019 Trail boss leaked during some single digit temps and I really freaked out. Local dealer fixed under warranty no problems other than having to drive a Toyota Corolla for three days.. they even replaced the Oil Cooler for some reason.
