Oil leak near transmission / rear main seal

[Van_Nik_75]

We don't have enough evidence to say that it's either common or uncommon. When I asked people to check their own cars, no one did. We only have 3-4 confirmed cases within the forum because there have only been 3-4 people that are actually aware of what the underside of their own car looks like. My car was leaking, but it drove great, shifted great, and had no symptoms.

I was going to start a poll asking people to post their mileage along with a picture of the underside of their bell housing; but, after seeing that no one cares enough to check their own car, and the fact that I had given up on my own, I figured it was pointless.

I'm actually not surprised that few people have checked their own car for this oil leak. Inspecting it involves removing both plastic shields under the car and safely raising the car to see underneath. If you're not doing your own oil changes it's a lot of work to inspect this yourself. Ideally it should be checked out by whomever is doing oil changes but I wonder how many dealers will just wipe the oil off the transmission with a rag and call it a day.

Yeah, I'm kinda in this boat. I'm curious but that's all... Not enough to jack the car up, remove the covers and look.. I'm not really concerned because oil levels aren't changing at all and I've let my dealer know. They'll check it out next oil change.

I'm due to change my oil soon, I'll be sure to have a look for any leaks. Let you know if I find anything.
In my experience, many of these types of leaks are just a bit of a messy nuisance, but not serious enough to have a noticeable effect on your oil level in between changes. Of course, it still shouldn't be happening on a relatively new car with just 10-20k on the odometer.

My dealership checked one of their G70s today and it didn't have a leak.. It was low mileage though. They will check mine when it goes in for oil..

I would think the opposite. I think the dealer would like to find that leak and fix it so they get paid by Genesis.

I haven't been given the invoice yet as I've been told that they're still finalizing the warranty claim is finished. I trust that I'll get a finalized version emailed to me to detail everything that was done and how many shop hours went into the job.

Did you get that invoice? Wandering how much this would be if you don't have that warranty. And if this happens to a 100k km car, would it be worth the fix.

Yes, I got the invoice. Unfortunately all of the totals are zeroed out. I was told that the job was about 50 hours of work.

So 6000$ US in labor, roughly. OOF!

50h.... That means at least a 5k job... Had to this this on an A5 Audi for 12h and Hyundai Santa fee for 5h

I apologize I didn't take any pictures, but my 2019 G70 3.3 is leaking in this area. I changed my oil today at 2966 miles, second oil change I've done, the first one at 560 miles. A circle about three inches in diameter, directly below the bell housing area, on the belly pan. I'll check it in a thousand miles to see what it looks like, and will report back.

Bummer...

Wow that's really low miles to be leaking. Makes me think it could be an assembly issue only impacting certain cars...

Why wait, just take it to the dealership so that they can address the leak under warranty. Sometimes engines are not sealed correctly in the factory. It got pass quality control it seems. Issues like that is why automakers give customers warranties for defects that happens ever so often.

An update for everyone. My car was in for oil today and the dealer snapped a picture for me.. No sign of leaking... 28Kms or 17K miles

 

[Slip_Angle]

I haven't seen a G70 or Stinger with the attached contraption, that I believe is a transmission heater?

I totally forgot about this thread and issue (been busy with my other new ride) and I have a service appt scheduled for next week. Thanks for reminding me, I will ask to see if my June 2018 build has this issue...

My update. Changed oil this week on my 2020 3.3 sport, one year old and still low miles at 5200. Mine looks clean with no drip so hopefully it stays that way.

 

[Husky]

So it's taken me longer than expected to reach my next oil change interval, between covid and other cars to drive, but I finally did my 15k mile oil change today.
Although there was no noticeable oil build up or staining on the belly pan, and the dipstick showed no loss of oil, the bottom of the bellhousing was a bit wet with some sort of oil. See pics.
It is directly in line with a driveshaft U-joint, which has me wondering if perhaps some grease/lube from that got thrown onto the engine, and the engine heat caused it to run down to the lowest point. Don't know.
If I ever take it back to the dealer I'll probably mention it. I doubt I'll own the vehicle long enough to have to worry about a more serious leak or failure happening outside of warranty.

 

[Husky]

Ugh, still not very good at attaching pics in this app. There were supposed to be three.

 

[Husky]

And another...

 

[Slip_Angle]

huh.. Is it just the picture or is there a slight oil ring around that bottom bolt? I just don't get how the dirty area goes all the way up and around... even if there was a slight leak..
