One of the other techs at works uncle has a Hyundai Tucson. Was just over 5 years old with 35,000 miles (warranty 5 years 100,000) when it developed a transmission noise. Had it into the main dealer who removed the transfer box and it’s got worn output to input shaft splines between gearbox and transfer box. Quote for repair was £14,000. He rings Hyundai UK and complains this car is low mileage with full service history with the same main dealer. Do they care? Nope not one bit.

That’s the end of his Hyundai ownership days. He told the dealer to put it back together and sold it to webuyanycar.com
 
230k mi on our SFS 2.0T.

I owned a 2.4 Sonata that got well over 125k mi but traded it in. Almost always used Conventional SN Valvoline. No issue other than slight ping until we changed the battery, plugs and wires at 80k. Car was solid.

Owned other 2.4 models (Other Sonata and Sportage) but never went over 80k mi. No issues.

I am aware of the recalls.
 
I sold my 2011 Kia Optima in December to buy a 2021 Kia K5. The Optima was one of the most reliable cars that I ever owned. It had the 2.4 in it and there were no mechanical issues. The only problem I had was having to replace the drivers side seat skin twice under warranty.
 
Not sure why its hard for some to accept that certain cars are 100k mile appliances. You drive them for a while then get another one. I rarely keep a car past 100k.
That's totally fine that you "rarely keep a car past 100k", but for many that isn't financially feasible. Also, I do have expectation that my vehicles will exceed 100K with normal maintenance, as we all should. Why would we had over $20K+ to an automaker for a new car and expect anything less?
 
I was JUST about to mention that the 1.6 Gamma had the lowest amount of warranty claims for many years. I don’t have that data anymore but it might still might have the lowest warranty claims out of Hyundai’s lineup. The 1.6 Gamma has been reworked in the last couple years so I can’t speak to its reliability.
Mines been rock solid 140k miles.
 
Every car maker has their issues.
Toyota......slugging up piston rings....Audi.....breaking piston rings in their 2.0t engines.
Hyundai is part of a crappy club...but they are not alone.
 
My father has the 2.4 GDI in his Sonata. All original minus a wheel bearing and starter part. The car has about 170k. He used to tow a snowmobile double trailer with household items when he was moving 8 hours away. He must have done 20 trips. It has been a good car!
 
Mileage? Irrelevant when considering the commute

Have 5500+hrs on a 2.4GDI in 90+% city traffic severe service driving. Its 10.5 years old and hasn't quit. The owner's manual covers severe service intervals and oil grades pretty well. And, I don't use the OE filter.

Anyone else monitor time?

Have so much fear of the theta-II that the wife gave the Sonata to her sister and bought a 2021 Kia Sportage with the latest version of the same engine/transmission combo.

The decade of Sonata maintenance maintenance/issues was no worse than my Toyotas, VWs, Mazdas, Hondas,..... and better than the domestics that don't have a driveway spot anymore.

I know, PM is unheard of in the world of auto ownership.

If I give an automaker $20K for a new car, I am not expecting much these days. If I hand over $40K+, then I would expect something built to a higher standard.

Ideally, 100K miles should be totally feasible. However, feasibility and reality rarely go hand-in-hand when it comes to cars. Automakers test their cars in a manner that is not consistent with the general buying public. They drive them for a week or two in the desert. Then they drive them for a week or two in the snow/cold/winter extremes. They might put them in climate simulators for a while to test durability of materials, paint, etc. They might shake a few pre-production cars on a shaker to check for noises and things. They aren't driving in stop and go, bumper to bumper traffic, along pothole riddled roads for thousands upon thousands of miles. They aren't doing the things to truly test a design for the rigors of daily driving. They leave that up to the buying public and then rely on the warranty and the dealer network to report problems (that they then may or may not adjust on the assembly line to resolve.) Then you throw in unavoidable manufacturing variances/tolerances and all bets are off.

Audi piston rings don’t “break” the 2nd gen 1.8 and 2.0 tsi can use oil but they don’t loose compression like a broken ring would. Also Audi will foot the bill to repair if you have full service history up to 100,000 miles. Doesn’t have to be main dealer history either.

Not anything like Hyundai.

Unfortunately it isn't like Hyundai, because otherwise they'd guarantee the engine/it's defects without service records for life.
 
I guess you pay your money then take your chances. I would rather know the brand will come to the table on a out of warranty major unit failure though.

Sorry - - - Yes they did.
2009 Audi A4 - - - broken piston rings.
When we had ours at the dealer the tech said they have re-ringed 10 A4's during that month alone.
He even showed me the piston rings in pieces....his words.
They break for this gen of the 2.0t audi/vw engine........

As a side note it took years for Audi to actually admit to a problem......AFTER being taken to court.
We took our A4 in 4 times over 1.5 years for this issue.

Ring problems have happened in the past.

the differential can be changed, and the transfer case. 14k is just a very bad quote. but 5 years warranty = 5 years warranty.

He may have broken them himself but I’m sorry they don’t. I’m a Audi master tech so know what goes wrong in there engines. It’s easy to break a piston ring and go oh look that’s broken. Not scraping the oil off the cylinders and causing the engine to burn oil, now that’s a different topic entirely.
