HIGH MILEAGE G70s???

[KUSHG70]

Hows it going everyone, just recently purchased a used genesis g70 3.3t HTRAC with 30k miles on it. Wanted to ask some Genesis veterans who have had the car for more than 30k miles and have touched 100k or beyond. Recommendations and advice?!

Welcome to the forum! What year?

Don't know of many g70s that have touched 100k, because that would require them to do 68 miles per day every day from January 1, 2019 to today. HOWEVER, i have a 2019 3.3 Htrac with 70,000 miles.

I haven't spent a dollar on it outside maintenance and modifications. Not kidding, I haven't had any "bring it to the dealer" issues with it. No CELs, no overboost, no parts peeling or cracking or rattling or falling off, although the black plastic trim near the sunroof looks to be worn down pretty quickly, and the drivers side seat bolster definitely looks like it has 70k miles on it. It's been dead reliable, I don't really have any bad feedback.

Hey thank you. 2019!

That makes a lot of sense! Would you mind sharing the mods you did to yours? I have downpipes, muffler, BOV, and intakes. Furthermore, how has the downshifting been treating you so far when braking?

That's awesome! Good to hear. Did you ever have the valves adjusted? If I recall, that's supposed to be done @40k (?) and is a pretty big job on these motors. Just curious.

It's at 60K, not 40. And nobody seems to do that. It's unheard of a modern engine needing valve adjustment at all, but Hyundai skimped on hydraulic lifters, not surprisingly. And that's for ALL its engines, including the 4 bangers.

Yep, what ELP said. 0 valve adjustment. I had the coolant flushed at 65k just for peace of mind, plugs done at 42k like suggested, diff fluid at 40k, that's really the only major ones. Just oil changes and cabin filters (and a set of r1 brakes) otherwise.

Not sure how much weight to put on this, since brake pulsation is not even mentioned in common complaints. I would've thought that would #1 by far. But... just a snack for thought: Owners Say the Genesis G70 is 1 of the Most Reliable Luxury Cars

Besides what has already been mentioned, the No.1 most overlooked maintenance item is brake fluid. A lot of folks don't even know this is a maintenance thing. Most mfr recommend purging with new fluid every two year. This is a must in hot and humid areas like ours down here in the warm Gulf Coast. If you live up north or the arid Southwest, you can stretch that out a bit. However, if you do any sort of performance driving, brake temps are a concern, and you'd well advised to have fresh dry DOT4 in your car.

This is something I need to work on, haha. All of my vehicles are overdue (although I don't track them, so not as critical).

I have a 2019 with 84,000km on it (Canada). Had the brake pulsation issue. Had premature seat wear. Have had the rear differential replaced twice. Tranny acting up some right now and looking to have fixed/corrected. This is my unmodded daily driver. I requested the valve adjustment be done at the last service but 99% sure they didn't actually do it.

Overall happy owner, hoping my 2019 is somewhat of a lemon as would like something a little more bulletproof from Genesis going forward. Tranny issues really put a damper on the otherwise enjoyable daily driver. Nothing else on the market at this price point interests me unfortunately.

Even I tend to slack off on keeping up with brake fluid flushing on our other cars.

 

[dillon.hockett]

I have a 2019 3.3t RWD and am just under 80k miles. Other than servicing all of the fluids and changing the spark plugs, air filters, etc i havent had any problems so far. Only things done on my car is exhaust, intakes, and its been lowered.

I'm not sure it's accurate to call this skimping...it's simply a different way to design a head. Having said that I'm not sure why they take this approach...I think one of the advantages of the design (cam over bucket I believe) is that it allows for higher revving. My KTM dirt bike has this design.

Plenty of good cars don't have hydraulic lifters...the Honda S2000 being one of them. I have hydraulic "lifters" in my BMW N52 engine....and the engine sometimes ticks. Fortunately going with thicker oil has helped a bit with that.

I believe the Genesis maintenance schedule calls for INSPECTING the valve lash...not necessarily adjusting. Obviously adjustment is required if a measurement outside limits is discovered. I'm sure that's not a small job. I've not read of anyone actually needing an adjustment.

The E46 M3 motor is another good example of a solid "lifter" motor (although granted that design is now over 20 years old). The nice thing about that design is that adjusting the clearance (with shims) is fairly easy. Nice design.

Thanks for sharing. I watched a video that details adjusting the lash on an S54. I like that system. For my KTM I have to remove the camshaft to change the shims. I believe this is also the case for the 3.3tt lambda II engine.

Several Stinger with 150,000+ miles. Even one with 200,000 miles. Crazy. No valve adjustments that I read about.

A few G70s with 100,000+ miles. The cars are actually quite reliable for the most part.

 

[jetrep]

Autotrader shows a G80 w/ the 3.3TT at 118k miles. Another with 116k. KIA stingers with 183k, 146k, 142k, 131k, 128k

All of the modern, high performance engines in cars (different brands) that I have had for the last 25 years at least have used solid lifter or tappets or whatever you want to call it. It not for being cheap, it's because hydraulic lifters just don't work well for high revving engines that need tight valve timing control. All of them have had the statement about checking the valve timing every 60K miles are so, and I never did that. I generally kept them to 200K to 250K+ miles and they never sounded like they needed adjustment. I've heard from mechanics that with the exception of Honda, it's just never needed.

 

[JCtx]

The 4-banger on our G70s is NOT a high-performance engine by any means. Heck, even its rev limit is a paltry 6,250 rpm; hardly 'high-revving'. It's cheaper not to include hydraulic lifters, period. And yes, my ex-M3 V8 revved to 8,400 rpm, and the S2000 to 9K (later ones 8K), so those are justified to use solid lifters. And the 3.3T is not considered a high-performance engine either, and doesn't rev high at all as well.
