Sonata I45 (YF - 2011+) :: Parking Brake Light Stays On At Startup Randomly
Dec 1, 2016
Sometimes 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.

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.

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.

So here is my issue, my parking brake light stays on. Ive checked my parking brake pads, the cables and the switch. They are all servicable and operational yet the light stays on...

I just installed a stereo in my daughter's 2010 Accent and tapped into the emergency brake wire to disable the DVD option when the emergency brake is engaged. Everything works fine except that the emergency brake light on the dash stays on dimly after releasing the emergency brake.

My son parked the car and I noticed the brake lights were on. After depressing and releasing the pedal a few times the lights go off, then 2 or 3 seconds later, they're back on even when the pedal is released. This happened all of a sudden. I'll pull the switch in the morning and test it, but what else could it be but the switch, right?

Why the parking brake light in my dash stays on, 2004 F150. Fluid in master cylinder is full, has no signs of leaks anywhere.

My vehicle: 2013 Sonata Limited - 4500 mi. When I park on an incline, set the parking brake then release the foot brake, hear a 'creaking' noise from rear. Dealer says "it's normal and nothing can be done" ? I don't think so...

I have a f250 super duty. I blew a brake line the main going to the rear. So the genius that I am I replaced the line an simple enough I decide hell why not replace the master cylinder too, so I did an I bleed the brakes an everything works jst fine but now the the brake light won't turn off I have tried everything not sure what could possibly cause the light to stay on. I will eliminate some suggestions, I bleed the brakes, the brake fluid is full, the level sensor is completely attached, the parking brake is not on, I pulled the parking brake completely out, even completely disconnected the sensor thinking it would turn off bu it didn't.

At first the passenger side front parking light would randomly not turn on until you gave the light assembly a hard tap. Now I am having the same problem with the driver side low beam light. I checked the harness connector and it clicks firmly into place. So, I am guessing there's something not grounded properly somewhere on the light assembly. I'm hoping that a light film of dielectric grease will work but I can't tell where to put it.

My father has a 2003 Mercury Sable. Earlier this month we took it in to have them check out a burning smell. They said the oil pan gasket was leaking and needed to be replaced. This led to an entire week's worth of work to get the exhaust system down to get to the oil pan gasket. Since that repair, the parking brake light will come on at random times while driving. It doesn't stay on too long and I can't seem to find a pattern to what triggers it to come on.

The 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?

TPMS 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.

Just 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.

I 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.

My parking brake light came on while driving. The car would coast at a low speed OK, so I think the brake was not on.
This happened in Yellowstone National Park at altitudes above 7,600 ft. and happened 4,000 miles ago and hasn't happened since. Taking the car in for an oil change today and I am going to ask about it.

On my '06 Sonata GL the third center brake light does not work all the time. I say all the time because it has a mind of its own; it works when it wants to. I have changed the bulb and it was working perfectly fine for months and months until recently when it suddenly began to act up.

So my May 2007 V6 Sonata with 143,000 km (89k miles) had the red parking brake light come on. Master cylinder level was low and there was evidence of something leaking on the driveway. Below the very back of the driver seat.
At the dealership they say I've got a leak in my brake lines. Say that the fuel lines should be replaced too since they are in the same compartment. So if one goes the other may not be far behind.
I was out of town and the car couldn't be driven safely so I was pretty much stuck there.When the dealership did the work a rusted bolt snapped near the fuel tank and they said that added an additional hour of labour to the work. In the end I wasn't charged for it. Tech said he had never seen a Sonata have the brake lines rust out like that. I got the brake and fuel lines done cause I plan on owning it for 6+ years.

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?

So 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.
