Bought the wife a new 2024 Chevrolet Tahoe with the 3.0L diesel engine back in May this year. Took it in for the first oil change after about 2,000 miles and noticed oil leaking in the garage. Just a couple of small drips - thought it was odd, but maybe the tech just spilled a bit when he refilled it. Put a white paper plate (taped down) to the garage floor to see if anymore oil leaked out. Watched it for about a week, and continued to get another drip or two. Called the dealership - took it in and they indicated, oh probably a bad oil filter, we will change it out for you, and you'll be on your way. Put a new paper plate down after she came home, and what do you know, a few more drips. We are busy folks, like most Aggies, so didn't have time to really mess with it, but was certainly annoyed. She drove it for a month, and I would say it dripped a total of about 1 tablespoon of oil in that time, with additional drips occurring somewhat infrequently, but maybe slightly more after longer trips when the engine got a bit hotter. She works at a school, so no idea how much leaked out while she was at work, but likely a similar amount.
Spoke to the dealership and took it in again, and now we were told that perhaps they had a bad batch of oil filters, and they would swap it out again. So sorry. Annoyed at the problem, but feel like the dealership and service techs are trying to help us. Second time around, took a picture of the oil on the plate, closer to two tablespoons now, and they added some die to our oil so the could see where the leak was occurring (no longer thought it was the oil filter). Drove it for 3-weeks, and took it back in and they have indicated they believe we have a rear main seal leak after seeing the die.
All covered by warranty (vehicle only has about 4,500 miles on it) and the service techs have indicated that this is a fairly common problem, which surprised me a bit, but I guess it's good that it's a repair they have done many times, so hopefully they are well trained and know how to fix it correctly.
I'm not a mechanic, and know very little about engines or how big of problem this is. Appreciate any thoughts from the forum on what to watch out for after the repair or what problems we might be in for in the future or other suggestions. Does it surprise you guys that this is a common problem for Chevrolet diesel engines? Tech said they are seeing it quite a bit in their trucks, tahoes and surburbans.
Thanks in advance for any advice.
