the dealership recommended "GDI service" be done when I had mine in at 31K miles.
The shop I've gone to for years and trust is recommending "injector cleaning" when I bring it in next week at 64K miles (I think only if it hasn't been done yet). It's supposed to help power and fuel efficiency, so I'm guessing they're talking about the same thing

 

I think they're trying to drain your wallet.

 

how did they notice anything "under the valves"? you know full well no one spent the time to scope all the cylinders.

 

Service advisor said they actually ran a small camera up in there somehow so they could see it.

 

^^^This^^^

I was just about to type the same thing.

 

Just follow what is in the manual. If some service was required it would be clearly spelled out there since your warranty is based on that. Remember the dealer is an independent company and their service bay is a major profit center.

 

Which suggests you might want to shop around for a dealer with an honest service manager

 

AMEN, good luck finding one
All the Hyu. dealers near me are crooks

 

Hello,
I had my 40K service done, (@38,000 miles, needed oil changed) last week. They tried to up sell me on that too ($169), I declined. There was a review I was watching last year about the SC and they said that since the 2.5T has both direct and port injection (SmartStream engine), it is much less prone to carbon build up on the valves, like direct injection only engines have. I think we just saved some money

 

Wife had her Tucson done at a dealer, and needed a new air filter, according to the service manager. They even brought out the dirty filter to show her. Funny thing was she knew what it looked like, as I showed her how to change one. This wasn't even the correct filter. I had a word later with the manager about this.

Same dealer installs the flashing 3rd brake lights for only $700, which is illegal for a dealer to do. They get around this by using a "Pulse" type light that technically doesn't flash. We used to go their because it was closer, now we don't.

Good for you. Both the engine and cabin air filter are so easy to change you should never pay a dealer for them. Takes no more then 5 minutes and requires zero tools.

 

"Decarbon and cleaning" would only apply to direct injection engines like my previous 2018 Honda Pilot one of the reasons I traded it for 2023 palisade which is also port and direct injected. Direct injection only causes carbon buildup, coking which requires the cleaning. I used to be a Honda fanboy but Honda is no longer leading auto technology and keeping direct injection only through to recent models is an insult to its customers.

 

Funny too that Toyota (who is well known for NOT innovating and for using the same old crap for 20 years....) was using dual injection since the early 00s with d4s. While vw and Honda have for whatever reason refused to go it 20 years later. When ford and Toyota (who again run the same things for decades) beat you to dual injection. It's dumb. GM even has it on old school cam in Block engines with the lt5 and ls2

 

Yeah it's bloody sin That these low lifes get away with that nonsense. I really despise people like that. But it is incumbent on the customer to know about their vehicle. Such as the sunroof scenario or 6 plugs, 4 cyl. and to call Bull on it. That goes for men and women alike.

 

This sounds similar to my experience last winter. The dealer recommended it after I was already home, which was weird. I believe in decoding the paperwork it translated to a can of this. I procured a can and DIY'ed.

 

I can comment about Honda. They are staying with GDI engines to pad the dealers pockets. We had a 2007 Honda accord 3.5L V6. It had a rubber timing belt that needed to be replaced at 100K miles. That same V6 engine is still in production, by Honda, with that darn rubber timing belt that needs replacing at 100K. Jamb the customer.

In 2015 at the dealer it cost me $1500.00 for the belt replacement service. That same service is now $2500.00. Dealer greed.

I complained to mother Honda in 2015 asking why in that day and age they were using a rubber timing belt on the 3.5L V6. I never got an answer. It's obvious they are saying with GDI engines to pad the dealers pocket, with carbon cleaning.

I agree about the rubber timing belt. I had a 2003 Tundra that had a rubber timing belt also. I just don't trust the rubber belts. I trust timing chains much more.
