2016 Tucson direct injection and transmission problems

I am considering purchasing a 2016 Tucson but I am concerned about two issues.
1. What have they done to prevent carbon build up on the valves due to direct injection of fuel into cylinders?
2. I have read some post saying there are problems with the DCT transmissions. Has Hyundai been fixing the issues free of charge via the warranties?

Not sure what they have done in an engineering sense. I know my dealer says that you must add a fuel additive at every oil change. I'm guessing that's to address the carbon issue.

Seems to be a scary issue, and there is a large thread devoted to this very subject which you have no doubt read. I can't provide any guidance, but I can say that our Tucson Limited AWD has had no issues at all. The tranny is very smooth, and we haven't noticed any hesitation or other problems. We are in love with our Tucson and the wife and I fight over who gets to drive it!

If you do not use top tier fuel, you "could" need a fuel additive ever so often. Don't get fooled into thinking they can charge you "just because" at every oil change. Even the owners manual tells you this. Never rely on a service advisors "advise". They advise for a reason. DI is not new and it's not as bad as some make it out to be.


Some are having a programming issue for the DCT, but it reality it does seem to be pretty rare, but those that have it, have it. There is supposed to be a fix out.

I'm in the same boat. The fuel treatment seems to be on par with other vehicles I've researched. The biggie is the transmissions. It's hit or miss as to whether the problems manifest or are dealt with. I've seen comments of the dealer stating it's part of it and Hyundai didn't answer the question but deflected. We'll see how warmer temperatures affect the transmission. Seems to be an uptick in complaints of overheating the past week.

I only run Top tier fuel. Shouldn't be a problem. Tranny on mine is ok. Sluggish downshift into first at intersections. Starts out in second gear a majority of the time making it feel slow. Sport mode helps a ton but will limit top gear to 6th unless manually shifted into 7th or using cruise control.

Other than that and the occasional gear hunting it's been fine.

Playhard even in Sport mode once cruising on the highway I have confirmed the tranny will shift into 7th, it occurs around 65 mph or so.

I love my Tucson Turbo. For reference in the carbon buildup, please watch this video about the Tucson's modified Hyundai Gamma Turbo engine.

The main source of complaints about the Tucson's dual clutch transmission comes from folks who expect a regular automatic. A dual clutch operates much differently, and is better classified as a twin clutch automated manual transmission. I quickly grew to LOVE this transmission.

Good luck!

That's the same engine as in our 1.6L Tucons? Hard to believe all that is going on under the hood. Cool video, thanks for sharing. I too love the transmission. I've had no issues. But it looks like quite a few people have been left stranded in the middle of traffic with a brand new car. That's a pretty legitimate complaint.

I'm also afraid of getting the transmission issues. It's making me think twice about purchasing a new Tucson.
