That said, here's the deal with the ATS. Quality control was inconsistent so if you get a bad car you'll The 2.0T timing cover is known to display "seepage", but it is not really an issue it seems as almost any one you look at has it and dealers usually don't reseal it unless it's visibly dripping.
Do you have anymore information on the timing cover seepage? Mine has been seeping and the dealership quoted me $1,000+ to reseal the cover. They said it wasn't an urgent fix. Perhaps it's not necessary at all as long as it's a very slow leak and I'm not low on oil?

All I know is it is extremely common with the 2.0T. The Cadillac dealer I bought my ATS from, certified pre-owned w/26k miles mind you, sold it to me with the seepage clearly visible. So many people have asked about this issue in the ATS/ATS-V Owners facebook group, and people's replies are always "it's normal". Lots of people have gotten that same answer from GM when they have taken their car to a dealer, they call it "normal seepage" and typically don't seem to do anything about it unless there is visible dripping somewhere. So, many people live with it but some have gotten lucky and had it resealed. Still, I have seen a couple people say even after their cover was resealed the seeping eventually started again. Maybe that's due to an improper job, maybe there's a defect with the timing cover, I don't know.

I had seepage for awhile and never saw the low oil light come on or anything, nor was the level low when I checked it a couple times. After that I felt okay just living with it, the worst part was being embarrassed to open my hood at Cars & Coffee haha. The oil was always visible on the driver's side from day 1, and I was willing to accept that. But when I noticed it had started seeping on the passenger side too that's when I became more uncomfortable with it. When I brought the car in for the axle seal replacement I asked about the timing cover, fully expecting to be told no, but they ended up resealing it and I could not believe it. I hope it never seeps again, but who knows.

Great, thanks for the info! I hate the look of my engine bay being dirty, but I also hate spending a bunch of money on something that might happen again even more. 😀

news flash: Nearly every car from every manufacturer has seepage somewhere... Most people never know because most engines are almost completely covered by plastics these days.

The timing cover on my 2.0T is always coated. Back when it was under warranty, the dealer said it was normal. I'm not a fan of an oil coated engine, but I put 5 quarts in and, every time, I take 5 quarts out, so I guess it's fine.

....The ATS is widely known and praised for its handling, near 50/50 weight distribution, good steering, and light weight. And it's cramped back seat haha.
That was actually a selling point for me! I was hell-bent on buying a coupe but with the ATS 4door, I get basically a coupe backseat without the long coupe doors. I can easily access the rear when I throw my laptop bag back there with the 4 doors. Plus it's still so cramped that nobody ever wants to ride with me. All wins too me!

Rarely have more than one passenger, not including myself, so it suits me well.



OP, I've been in a CPO 2.0T AWD 2017 for a few months. Only thing I've had issues with so far is the transmission shudder the 8spd is known for. Dealer did the latest TSB fluid swap and it's been fine since (over 1,000mi since).

As others have noted, one of the biggest things is to watch the axle seals. Make sure the vents aren't clogged,and all should be well.
