Question about 2011 Hyundai Tucson

2 Answers

I have a 2011 hyndai tuscon and my engine revs unexpectedly periodically while I'm driving. I can be on the highway or just running erronds around town. It's not floor matts, I removed them. My check engine doesn't come on when this occurs. The dealership doesn't know what it is. I'm at a loss. Does anyone have any ideas what this is? Transmission maybe? How can I get this fixed? Thx!

Our Tucson is doing the Very same thing! We bought it last year right off the Truck, never been driven before we got it. And about 4 months after we got it it started that Reving thing! We took it in to the dealership and they coudn't find anything wrong with it. so they made a report but said there was nothing they could do if they couldn't find a problem. Now it's doing it Again!

Hyundai tuscon: petrol. after about a 100 miles the revs start to limit to 4000 and reduce to about 3200. This makes driving tricky especially when overtaking. changed timing belt,pully,fuel filter,c


I'm not familiar with your Hyundai, but the symptoms could be several things, I am thinking 1 in particular. Change your coil pack. I think you have the single coil pack that runs all cylinders. They can break down inside and not create the 20,000 volts or so that you need consistently. When you get to running temps, the coil gets extremely hot and can start breaking down and losing it's power.

Try to rev the engine while at neutral if you get the same vibration to pinpoint if its from the engine or the drive shafts. If the issue occurs at a certain rev it may likely be the variable valve unit. Check if possible if you can get errors from the computer.

What gear can I used for highway D3 or D4


use d4. d4 is for normal driving. d3 is to down shift the transmission in case you wanna pass. use d3 only if you want to down shift because if you leave your car in d3 on the highway, it doesnt allow the 4th gear to engage, causing your engine to run at higher revs, not only wasting more gas but also making your engines life last less. hope this helps. if you need more help, let me know. goodluck

Car stalls when driving


Take notes , when this happens.
For instance : engine warm or cold , outside conditions (cold , hot) , car driven for a while , long or short distance when problem occures etc.... , that may help for diagnosis.
It very well may be temperature relaited , sience it has to sit (cool off) for 5 min.
Ignition coils sometime do that.
I'm mechanic shop owner and intermittent problems are the hardest one , so any piece of iformation on above mentioned events may give a clue.
Good luck.
