Sonata I45 (YF - 2011+) :: Gas Gauge Level Will Go Up And Down While Driving
Apr 18, 2016
I have a 2011 Sonata Limited. I have issues with the gas gauge. At times when I start the car I can literally watch the fuel level go all the way down to Empty and the low fuel light will go on. I can leave the car running for a few mins then it will go back up. I can also be driving and the gauge will go up and down. I have gotten to the point where I just reset the trip counter and monitor the miles that way.

I was auto crossing yesterday with about half a tank and I noticed my fuel gauge read 40miles to empty after one of my runs. I filled it back up to the top and it still reads almost empty. Im out of warranty so Is there something I can check before taking to the dealer?

I was wondering if there is a dipstick for checking the automatic transaxle fluid. I have searched my car and the owner's manual but have yet to find anything that addresses the auto transaxle. If I have managed to overlook it just give me a page number in the manual.

My 2012 Sonata has the erratic fuel level indication. I've read enough posts here to pretty much assume I need to replace the sending unit.
I could go with OEM, but it seems this has plagued Hyundais for many years and across many models.
While I have the (fuel pump, filter & sender) assembly out (of the tank), when (miles) is it recommended to replace the fuel filter?

OK Wife has been coming home and the car smells like coolant. The tiny hose from the rad cap to the reservoir isn't pressurized and popping the res cap does not release pressure. Do they are supposed to pressurized?
The coolant level is in the exact middle of high and low just after a 25 minute highway drive. I cant see any puddles or leaks anywhere on the tray; but I have pulled the tray anyway to see if leaks show up on my floor. Temp gauge never wavers at all from what she tells me.
This is a bit perplexing. Maybe a bad rad cap?

For the last 60 miles, my fuel gauge is showing major usage,for every 6 miles it is using 1/10 of gauge.
When I go to fill gas it takes only less than 1/3 gallon of gas then it clicks full.
So I have driven 24 miles and it is showing 4/10 gauge used up.
No smell of gas

I just bought a 2014 Sonata GLS two weeks ago and have a question about the car icon below the engine temp gauge inside the tachometer. Looking for description of its function? It shows the card doors open. I believe it also shows the trunk open. But the owners manual doesn't mention it and I can't find any information online about everything it shows.
Specifically, I'm getting a low tire pressure indicator (we just started getting temps below freezing here). When the car is driving, the little car icon shows the tires, but the back driver's side tire is missing. Does that mean that that's the tire with the issue? Not a big deal, but I'm still figuring the car out and that would be a really cool feature. Also, does the little car icon show anything else?

After a cold spell this past winter 3 dots appeared on my car's temperature gauge LCD display. The dots are also displayed when the ignition is turned off and a door is opened .

Yesterday in the pouring rain the low pressure tire gauge in my 2014 Sonata lit up in the middle of traffic. I drove to the nearest gas station and checked the pressure of all 4 tires, even though the diagram on the dashboard pointed to only one tire. Filled and checked all the tires again (still in the pouring rain) and drove off, only to find that the low pressure light was still on.
I was told by a mechanic-friend that I should bring it in for service and have the sensor reset. I didn't have this problem with my 2011 Elantra. Maybe if I just kick the dashboard it will reset the sensor...

I don't have any lights or gauges working at all. The sonata car picture comes up when I get in but once the car is started this goes away too. Headlights and interior lamp is about the only thing working on the car. 2013 Hyundai Sonata?

I was driving to work but Sonata stop in the middle of the road acting like ran out of Gasoline. But the fuel gauge showed 1/4. I was tried to crank few more times but didn't start. Called road side assistant, tow truck took it to nearest Hyundai dealer. After they inspect, your fuel gauge sensor is wrong, fuel tank is empty.
My 2013 sonata is showing 61500 miles on it. They asked me $450 to replacing the sensor because bumper to bumper warranty covers up to 60,000 miles.
I decide to fix it later, put little bit of gas and than fueled up all the way to the top at nearest gasoline station. Fuel gauge works again, it is now showing full tank. I do not know how long it will last but it is scary.

2011 Sonata GLS, 95,000 miles.
This just started yesterday. While driving, the RPMS suddenly drop off. Depressing the gas pedal doesn't command any power output, even if I floor it, the RPMS continue decreasing and there is absolutely no power. The only way to keep moving is to completely release the pedal and then depress it again.
The transmission has been serviced twice by me and shifts smoothly. Should I plug a scan tool in ?

I was driving my car on Sunday and twice within a span of 30-45 minutes the car stalled while I was driving and just shut off. I had driven 70-80 miles earlier in the day without stopping, and after about an hour, went back out to run some errands. After a light turned green, I proceeded through the intersection and made it halfway before the car stalled. Luckily, it was on an incline and I was able to coast to a parking lot out of the way of traffic. I tried to immediately restart the car, but the engine would attempt to start, but not fire, like the alternator was faulty.
After waiting 10 minutes, the car started up, and I immediately tried to make it to an auto part store. I made it about 10 minutes down the road and the car stalled again in front of the auto part store. They came out to check the battery, alternator, and started, and said all were fine and they were not showing any issues from their test. After waiting another 10 minutes, the car started up and I was able to make it home.
I dropped the car off at the local dealer on Monday and was told they are not able to replicate the problem, and the computer is not showing any codes, so they are not sure on what to do or fix.

My mother has a 2012 sonata. She told me that her drl will shut off when she turns her headlights on. Is this normal or is something maybe wrong. She also mentioned that they will sometimes shut off at random while driving.

I have an issue with the transmission not allowing me to shift from Park if I drive for couples of minutes unless I re-start the car. Also, if I drive for couples of minutes while I'm putting the cruise control on Standby mode or ON, it will shut off by itself along with the light for the economy driving mode.And again if I re-start the car everything will work.
This video will show you what I'm talking about : [URL] ....
My car is GLS 2011 and has 85,000 miles.

I have a Sonata 2012 limited version. Lately its been loosing power while driving. It will going around 60 for instance and as I am pressing the gas all of the sudden the rmp begins to drop and the car doesn't respond to the acceleration of me stepping in the gas. It is not until I completely get my foot of the gas and re-engange again that it will recognize it and continue accelerating. It will doing whether I am going 60, 40, 20 mph.

About a year ago I was driving along and ran into some traffic. A few minutes later I noticed the AC stopped working, (it was about 85F out), and then I noticed that the engine temp was getting much warmer. Had never seen this before. The car had about 70k miles on it.
Turned on the heater and was able to get the engine temp down. Immediately took it to my local mechanic, who checked that the compressor was running, but was unwilling to tackle this diagnosis and recommended I take it to the dealer.
Took it to the dealer the next day and they diagnosed a bad compressor which they replaced for $1200. However the very next day after I picked it up the very same thing happened. Engine overheating and the AC turns off.
Pretty disappointed in this - I expected the dealer to be able to fix this, especially for $1200. So I left it with them for a week, and still they were not able to diagnose or duplicate the problem. Asked me to come in when it is happening, but since they are about 30 minutes away and it only happens once in a while I gave up on that.
However, ever since then it will occasionally have the same issue. I can usually resolve it by parking for a while, or by turning on the heater for a while. The AC does work most of the time, but of course this problem usually occurs only on very hot days.

So I have a 2012 Sonata with about 80k miles on it. I bought it used a few months ago. It has recently started having issues with the brakes.
When the car is cold and I start driving, every time I push down on the brakes they will do a quick grab after a few seconds. Sometimes its a slight grab and other times its a jerking grab. After I drive 10-20 miles or so and it warms up this goes away.
