100k + miles: My experience

[Paraiks]

My car: 2015 Genesis 3.8 AWD Ultimate.

I recently went over 100k miles and here’s my experience with what has gone wrong:

1. 20-30mph flutter was fixed at dealership while still under the 60k mike warranty.
2. The amber bulbs kept burning out so I replaced them with LEDs.
3. Passenger side 12v socket went out on me.
4. The sunroof creaks and sometimes doesn’t close unless I give it a push.
5. Changed all four tires. One tire was worn much worse than the other three. Haven’t had issues with that since . *I know it’s maintenance and not something wrong with the car. Just wanted to mention it.

That’s it! As of now, my car has been great and is still running smoothly. I’m diligent about cleaning the car (both inside and out) and doing all the maintenance required. I do my oil changes at Walmart because I ran out of dealer oil changes. Note: if you do your oil changes at Walmart, you need to take your own oil filter which you can find at AutoZone for about $8.

If you have questions, hit me up!

Only 1 set with 100k? If so, that's damned good.

I bought the car with 42k miles and the tires it came with were new. Ran through those then got me some new ones.

Sounds great, since the G80 is essentially the same car but with refinements and a few new features. I'll drive mine about 8-9k milesa year, so expecting to get 10+ years out of it.

Congrats on your success.

Edit: I bought the G80 because I liked it. I was going back and forth between a new Q50 and an Acura, but found the larger G80 had the features I wanted for less money. I was tired of looking, so I just bought it. I had heard the G80 was "based" on the Hyundai Genesis but didn't realize until after I bought it that it was the SAME car! I mean really, if you go back and do a model review of the '15 Gen to the '19 G80, there are few changes.

I bought the base G80, if I could do it all over again I probably should have bought a '17 or '18 Sport or Ultimate for about the same price.

So true. The bones and skin of the Genesis(2015-2016) and G80 are the same. The interior changes and improvements are the only real differences I believe. Hyundai seem to believe in the saying"if it is not broke, do not fix it"

The car is beautiful and well designed, so it is hard to improve on it.

@ Paraiks Thanks for helpful review.

My 2016 3.8 AWD Luxury is only @ 38700 kilometers
& so far trouble free other than michelin primacys
are wearing quickly. What tires did you replace with
to get such good wear?

My sunroof also creaks especially in cold weather backing out of the garage.

Debating buying an extended warranty to cover the car until August 2024 0r 100000
kilometers for $1924 from Hyundai.

How many miles now? Considering a 2014 Caddy CTS with 60k miles or a 2017 G80 w/ 130k miles…I drive roughly 50k miles yearly so I’m slightly worried abt the genesis in long term.

Man, I would be more worried about the Caddilac CTS than the Genesis G80. GM 3.6 engines are not the most reliable pass 100k, nor the transmissions. Just look up GM 3.6 engines used in CTS on the web. Hell look up any GM engine used in the CTS and the choice would be clear.

The G80 engine(3.8 or 5.0) would the best choice if it was properly maintained.

Precisely what I was thinking boss. Problem is the Genesis has 130k miles currently- do you guys really have faith in it lasting two years aka to 230k miles or so for me? I’ve had cars last that long before, but lately have been more spoiled with low mileage cars so I’m slightly worried about a higher mileage vehicle. Truly love the Genesis and would love to hop on the deal and buy if it’s worth it.

Yes, with proper oil and transmission fluid changes. Like in the video, oil changes are key to keeping timing chain driven engines running without major issues. I change my engine oil every 4k miles in my 5.0; so it "should" run well for long time pass 100k miles without needing a major overhaul.

The question is how often did the owner of the 130k miles Genesis the oil? I would pass on that car since I feel that most Genesis owners will stretch out oil changes until the oil is very old usually about 7k-10k miles. But, if have to choose between the two I would go with the 130k Genesis over the CTS with 60k miles. Non-LS GM engines are not reliable in my opinion.

Oil was changed every 6-7k miles- however it’s now been 8k miles since the last change.. definitely hear that on the Caddy though. Not too sure what I’m wanting to do at this point. Really want to keep to luxury cars as I hate your typical Honda’s and Nissan’s.

Passing 100,000 miles, I'd be changing my oil religiously at 3,750 to 5,000 miles on synthetic. Drain and refill the transmission oil every 60,000 miles, and I'd replace the trans filter/oil pan every 120,000 miles.

Personally I would not buy the high mileage G80. Timing chains components cost a lot of money to fix and that car may have some timing related issues already. I would try to start the car early one morning and listen for any start-up chain rattles; which usually means the tensioners are bad. Expensive to replace since it requires the front engine cover to be removed.

I would try to find a G80 with less than 100k miles so that you hopefully get one that has not been abused pass the point of no return. Longer oil changes(7k or longer) only benefit the dealership service departments and owners who will dump the car before the engine has 100k miles or just after 100k miles before the major engine related problems occur due to the longer oil change intervals. Especially with a
chain driven engine.

Note: I read somewhere that many automakers consider 150k miles the lifespan of modern engines and transmissions before needing an overhaul and their normal service recommendation is based on that metric. Therefore; if Hyundai recommends that the G80 can go 7k-8k miles between oil changes then it may last twice as long without major problems with 3k-4k miles oil changes.

I test drove a 2017 G80 with slightly over 100K miles on it, and it drove like a DREAM. Smooth. Quiet. All the electronics worked.

I wasn't planning on buying it, I just wanted to know what mine would feel like 100K miles later. We've all rented cars with 20-30k miles on them and the interior is coming apart and it shakes, rattles and rolls.

Not so with the Genny.

My 5.0 is nearing 100K (~94,000) & still runs like a train. I religiously change the oil every 3 - 4K. Still smells new inside.

My only major expenses have been "consumables" (brakes, tires & etc.) and an alternator & battery. My old Infiniti was becoming quite the money pit by the same mileage.

Funny - my previous sedan was an Infiniti M35x and I LOVED it, (and maintained it meticulously) but it was pushing over 100k miles and thought it would be prudent to buy the Genesis.
No remorse here.

150k? Sounds like a BMW!

Find a G80 with lower miles than 130k.
You're welcome.

The last 20K miles that I had with my G35s was pretty expensive - Cam position sensors (common), Mass Airflow sensors, A/C compressor, alternator & a water pump. I did love it though... It made you want to drive it like you stole it!

 

[TinsleyC]

Interesting you guys say that, I sold my '09 G37 when it was 10 years old with 80k miles on it, and it was starting to show signs of needing work. Got $9.5k for it, bought the G80.
