Whenever I start my 2011 Sonata Turbo after it has been resting overnight, the brake warning light comes on and stays on. It's not immediate—it usually takes five to ten seconds, and whether the emergency brake was on when I started has no effect. Once it goes on, it cannot be shut off without shutting off the car and restarting—at which time it acts normally. The braking system is fine.
View 4 RepliesSometimes when I start my car, parking brake light fails to go off. I know this is usually indicative of low brake fluid, but mine is not low. I rarely use the brake so I don't think it's the parking brake switch either as it only happens if the parking brake is not engaged. Never happens on the occasional use of it.
Restarting doesn't seem to work unless I set the brake, restart, then disengage it. Very strange problem. Not a big deal but is a bit perplexing. I never see a CEL or any codes generated at all.
I recently (July 2016) bought a 2012 2.0T Limited with 14K miles. Got an awesome deal on it and really love the car. About two months ago the car had a total loss of power/boost. I took it into the dealer and they performed a wastegate actuator adjustment (something I will be doing on my own now if it becomes a problem again). Now at about 21k miles I'm having a different issue. Here is what's happening:
Accelerating from a stop the car feels as if it's falling out of gear intermittently. Once it happens and I press the gas more/floor it, the car doesn't respond. If I let off the gas and then press it again, the car will then start to accelerate again. On the highway cruising at 70ish, the same thing happens and it even oscillates with constant throttle like its down/up shifting. The ESC light came after a 20 mile highway trip of this oscillation. No CEL. When I got off the freeway, the navigation screen said there may be a problem and I should press the bluelink button.
When this is happening the cruise control either doesn't work at all or the "cruise" light will come on but I can't set a speed. Tonight I noticed in the rear view mirror that the brake light stays on or even flutters after I brake which corresponds to when the cruise is or isnt working as well as when the car intermittently falls out of gear/oscillates falling out of gear with constant throttle. If I notice the brake light is on without actually braking, I can take my foot and pull the brake pedal towards me which turns off the brake light and then the car seems to work correctly as well as the cruise control. The car is driveable but definitely something is wrong.
I should mention that I checked the voltage for the wastegate actuator and it is 3.97v which I believe is within tolerance. All of these issues with no CEL.
Over the past 4 months I've had the brake warning light, the one that comes on when you press the parking brake on, come on randomly. In each occasion turning the car off and then starting it back up clears it for the rest of the day. I had it happen 5 months ago, a couple months ago, two weeks ago on new years and then this Saturday and Sunday. Took it to the dealer today and it shows no codes but they managed to get it to come on once. They think its an electrical issue which makes no sense to me.
View 21 RepliesHaving issue with the hand brake? It works fine, just when I want to release it, the brake light stays on and when you drive away hand brake warning comes up and I have to play with the handle to make the brake light go away after release...
View 8 RepliesI have had this 2008 ES 350 since 2010. Best car I have owned. EXCEPT for winter driving as the wheels stop spinning and it leaves you stuck. give me the old rear wheel drive any day. The main concern right now is, my dash has a red "brake" light that has been on for a week now. sometimes in the afternoon it goes out for a while. I have almost 42,000 mi. would that indicate I need to change the brake pads, which in turn lowers the fluid?
View 1 RepliesThe air bag light in the dash came up, and stays up. I checked for connections under the seats, and tried the battery disconnect thing. N/G. It's my son's car, and until he brings it in to get the code read, is there anything I can do in the meantime?
View 4 RepliesMy 2008 has the airbag warning light on - the dealer wants to replace the whole passenger seat bottom. They also say as long as the light is on no airbags will work. Is this true and do I have to just cough up the money and replace this?
View 5 RepliesTPMS sensor has recently came in and stays on. However i checked all 4 tires and the pressures in them are at the appropriate values. I am assuming this could be related to maybe the system just not "seeing" one of the sensors or something. I heard if you use an OBD2 adapter you can see the values reported and it will show exactly what tire is reporting the problem.
View 13 RepliesJust purchased the 2012 GLS this past Saturday and everything is good except for one thing. My dome light even in the "door" position stays on after starting the car and driving. I have to manually switch it to off to turn the interior light off, which is annoying. I called the dealership today and they had no prior experience with that problem. BTW, I did have a sunroof installed.
View 4 RepliesI have a 2011 Sonata and my overhead light stays on in the DOOR position. I didn't have problems until I took it to a car wash a few months ago and I think one of the workers did something by accident because it hadn't worked since. I have to keep it OFF at night but I hate entering my car at night and no light comes on.
View 1 RepliesI'm driving a 2010 Hyundai Sonata and just recently one of my brake lights has been acting up. Everything works perfectly fine as long as the head lights are off; however with the head lights on, when I depress the brake pedal my driver's side tail/brake light goes out. The center brake light and passenger side brake light work just fine regardless of the head lights being on or off. With the headlights off, all the brake lights operate normally when the pedal is depressed.
View 6 RepliesMy 'check engine' warning light just came on after only 12,000 km on my 2011 GLS. What emission control part would be the first to fail? I ran my 06 Sonata 100,000 km+ and never saw any warning lights! And no, it's not a loose gas cap!

Only thing working on instruments on steering wheel is the left side is the radio and phone and volume and mode right side of steering wheel not working but nothing is illuminated!!!!???? On wheel
Today I drove about 250 miles, round trip. About 75 miles from home, my TPMS warning light started flashing, then came on steady. I also received the Blue Link message about problems with the TPMS system. We pulled off the interstate at the next service station (about 3 miles) and checked all of the tires. All 4 read exactly 33 psi.
Restarted the car and continued on. After about a mile, the light turned off. About 10 miles later, the light started flashing again. It flashed for about 2 minutes then shut off again. We continued home without seeing anything more from the light.
The only thing at all out of the ordinary, is that the temperature has changed from a high of 35F earlier in the week to 70F today. There is a lot of moisture on the ground. Is it possible condensation may have affected a sensor? I have a 2013 GLS with 2800 miles on it.
The light flashes then turns solid. I checked the pressure to find 32lbs in the tires. I pumped them back up to 36 front, 35 rear (per suggestions here to minimize steering wander).
The light remains on. Knowing the pressures were fine, I have driven it several days to see if the light goes out on its own. No dice.
While driving last week, the wife asked about this and we pressed the Blue Link connect button. The service rep who responded said she saw no pressure warning on her remote panel.
Over the weekend, I tried inflating the tires to 40psi, thinking that the higher pressure would reset the light and then I could lower the pressure to normal levels. That did not work, either.
So yesterday, I called the dealer and the service rep said the system warns of BOTH under pressure and over pressure. She suggested setting the tires to the "sweet spot," at 35psi. I did this, and the light remains on.
I guess I will need drive to the dealer and let them piddle with it. I like the system, or at least the idea. But I hope I don't have to drive to the dealer after every attempt to maintain the tires.
My driver side brake light keeps going out. I replaced the bulb couple of months ago and had to replace it again. Switch the socket? Switch to led bulbs?
View 5 RepliesSo I was told I had a brake light out? Went and bought new bulb and replaced. Turn on headlights and the single filament lights. so when brakes are applied the second filament should light up that give the brighter affect.
Well when brakes applied the bulb goes out completely? Take foot off brake and the single filament comes back on. The other tail light operates as it should. Even used bulb from working tail light with same results.
I have a 2014 Hyundai Sonata that is giving me a "Low Tire Pressure" warning. I have checked the air pressure in all of the tires and I still get the error. How I can find the tire pressure that is giving me the error?

View 6 RepliesA month ago my ESC light started coming on and the dealership replaced the brake pedal switch per the recall.
Here in the last week or so, I've noticed the brake pedal is very sensitive now and will sometimes stick causing the brake lights to say on after the car is turned off.
Pushing on the pedal just a little bit (pushing down maybe less than 1/8") will cause the brake lights to turn on and also kick the cruse control off.
