Maintenance and service is in the owners manual

There are generic service due notifications that pop up in the display but they do not state what the service is and are not in sync with the manual mileage. The only real service is the coolant change

 

You can adjust the 5,000 mile service interval in the car's settings to match the manual's 8,000 mile interval. I'll be doing that next week when I get the 8k mile service done.

 

We own a 2023 I5 and-being a pilot-I’m religious about vehicle maintenance. We’ve had no issues whatsoever during the 16 months and 7,500 miles of driving. When we received notice of the ICCU recall, we took the car to the dealer and had that done.

About two weeks ago, I received a notice from Hyundai that the car was due for a “multi-point inspection”. I dutifully made an appointment and took the car to the dealer. When I got there and the service guy had checked his records, he said, “Weren’t you in here a couple of months ago?” I told him ‘yes’ but that I’d received the notice from Hyundai that it was due for a multi-point inspection. He replied, without seeing the car, that everything was fine and no need for an inspection.

When I told him I’d received a notice and that I worry about warranty issues if I don’t have services done, he dismissed me and said to “let the car tell you what’s needed”. So I left, without having the inspection.

That “let the car tell you…” seemed a bit strange and a bit worrisome to me. But what do you folks think about that advice?

The service guy is an idiot. This is why I'll never buy another Hyundai product.

 

As an engineer who’s spent a many years reviewing maintenance schedules for highly technical and complex systems to ensure that the required maintenance is being done while removing the unnecessary work to ensure that these systems continue to operate safely within their design specifications, while not causing the maintenance staff unnecessary work, trust me when I say that for cars, a lot of what a manufacturer states is ‘required maintenance’ appears to be there just to make sure you take it back to a franchised dealer so they can make money.
eg: oil changes for the engine in ICE cars, modern, fully synthetic lubrication oil simply cannot be broken down by anything mechanical in an engine (gearboxes are different), it requires far more extreme conditions to achieve a chemical breakdown, it can get contaminated (as in a diesel, with combustion products, or if something breaks in the engine ) but it can’t be damaged or deteriorate in normal use. So it simply does not need replacing at anything like the intervals most car manufacturers state, it’s why many were able to safely adopt ’extended’ service intervals after many consumers both complained & questioned the frequency of such work.
inspections, hmm, these tend to require someone to simply look at something, which cant really achieve anything without detailed tests such as checks of tolerances or performance, which would require many hours and a lot of test equipment, to check that something is working within its design specs, so just observing something (or giving it a good optical bollocking!) isn’t really going to do anything unless there’s a reported defect, in which case it’s checking for anything obvious.
So I tend to take a massive pinch of salt when a car dealership (dealerships seem to be far more anal about this than other garages) insists that various maintenance work is a ‘requirement’. Most appears to be a desire to take more money off a customer.
The most most common example I’ve come across apart from oil changes is brake disc wear, my wife gets this mostly (odd that!), the garage will tell her that the brake discs are badly worn and need replacin, when questioned, they usually explain that there are ‘ridges’ on the outer edges, indicating wear, well, good, they are designed to wear in that way as the pads never completely cover the full radius of the disc, it’s a wear indicator. Anyway, my standard question is always, ‘how close to the wear tolerance is the disc?’ I rarely get anything other than ‘we haven’t measured them!’ As an answer. All brake discs are case hardened to a min thickness, the wear tolerance is usually 1 or 2mm less than the design depth of case hardening. so if the disc thickness is outside that figure, it’s fine. we've never had to replace the discs on any of my wife’s cars due to wear, it’s just the dealers doing a bit of scaremongering.
So I’d really, really like to know what Hyundai think is so poorly designed or unreliable in the I5 as to require an 8k mile service!

 

I've seen some people question the 30,000 mile coolant replacement along a similar line of thought to your points about the modern synthetic oils in ICE vehicles.

 

Based on the replies, I will adjust the car's maintenance schedule to match the scheduling shown in the warranty. I cannot be denied warranty-covered maintenance if I follow the written schedule. Thanks for the advice. We can close this thread....
