Electrical-wiring - Hyundai - Elantra :: 2008 - Accelerator And Brake Pedal Would Not Engage
Jul 23, 2013
On my daily commute in stop-and-go traffic, on a bridge, headed downhill, suddenly neither the accelerator nor the brake pedal would engage in my 2008 Elantra. Cars in front of me had sped up, then ground to a halt, and I was coasting downhill toward them, at a pace too fast for the handbrake to stop me. I couldn't downshift either (the car has automatic transmission, but shifting to low lets the engine slow you down). With nothing else to try, I shut off the ignition and then turned it on and, amazingly, all was back to normal. The dealer didn't find any trouble codes in the computer so they say the car must be OK to drive. But I don't feel safe driving the car. This might have happened and what I can do to fix it?

I need to know how to unplug the accelerator wiring. I lift the little red lock on the side, but then I still can't unplug it. I've tried pressing on different places like is so common with other plugs, but no luck.

Working on a 2002 Hyundai Elantra GT. 4 disc, no ABS. Problem is the brake pedal goes to the floor without much force. I bled all 4 lines, but no improvement. Rigid lines from the brake master cylinder to the rear wheels were very corroded, so I ran new lines. The old ones pretty much fell apart when I took them off the car. I also replaced the brake master cylinder. I tried to bleed the brakes again, but couldn't get much (if any) fluid pressure at any of the wheels. Yes, I found a couple leaks at the junction points for the rigid lines, but I re-flanged those connections and got rid of all the leaks. Still no real pressure when trying to bleed.
So, I tried a second, then a third master cylinder with a new attached resevoir. No improvement. I bench bled the snot out of this third master cylinder because the symptoms clearly suggest air was likely trapped somewhere in the system. I used a wood dowel to fully actuate the cylinder many times after all the air had been released while I had short clear hoses running from the master cylinder outlets into a little plastic cup filled with clean brake fluid. I wanted to make sure there was no way air could be in the MC, and no air drawn back in when I released the wood dowel.
Next, I quickly capped off the MC outlets and connected a hose to each brake line individually where they normally screw into the MC. I then let clear fluid drain through each line until it was spilling out clear of each caliper bleeder with no air bubbles. So, no lines are kinked, clogged, or contain air.
I took every precaution to keep air out of the system, yet when I push the brake pedal, there is still virtually no real pressure generated by the MC. The power booster rod is shoving the master cylinder in as it should. I don't think there's any problem with the power booster.
I've used gravity bleeding, manual "push & hold the brake pedal" bleeding, vacuum bleeding, and I'm certain there is no air in the lines or calipers. Still no significant pressure coming from the MC when I push & hold the brake pedal to the floor. It takes maybe 20-25 pounds of foot pressure, but always goes completely to the floor with all the bleeders closed. If the pedal is held to the floor, fluid slowly seeps from the bleeders. I'm used to it spraying when doing this on a healthy brake system.

My rear brakes developed a squeal when the brake pedal was released. My dealer replaced the rear brakes & disks at about 57000 miles. I had taken a salesman from the dealer to get an appraisal & he told me that it sounded like a simple adjustment would fix it. 2005 Elantra

I have a 2008 elantra. It has 71600 miles on it. New brakes, & tires. 2 tires were changed year and 2 more the previous year. I have been hearing a constant sound and starting to feel a mild vibration on the pedal. First I went to a mechanic and he said I need to change the belts. Got that done, no respite. Next went to another, he said i probably need to get the wheel alignment done as the tires seem 'cupped' on the inside.
Went to the dealership, they looked at it said the same abt needing wheel alignment and asked me to change the timing belt!. Still same sound. Went to Sams club to look at the tires & they said check the brakes, tires are fine, it cannot wear out so soon and its not covered under warranty. Brakes got checked out as fine. Went back to Sams again and was told to check Suspension and Struts this time. Went to a mechanic and he gave me an all clear this morning! I am going on a road trip and don't want to be in an accident!

After driving in the rain and starting the car again after a few hours (as in starting the car again after work, or starting it first thing in the morning) the following happens: As soon as I release my foot from the brake pedal to go into "drive," there is a "thunk" sound from the rear of the car as well as a lurch. A soft "thunk" may have a soft 'thunk" sound, but a louder thunk will have a pronounced lurch/jerkiness from the rear. The car drives OK and has no problem with braking when I apply the brakes.
It happens only after driving in the rain. The dealer says the sound and movement are the normal result with disc brakes wearing off the rust on the rotors. Other wet weather concern (happened once): while driving in a couple inches of snow, the brakes began to grind and eventually failed to bring the car to a stop. Dealer rotated the rear rotors (due to uneven wear, although I had the car only two weeks at the time) and installed new rear brake pads. He said grinding brakes on an Elantra are normal in rainy, snowy, and dusty conditions. Is my car really safe to drive? Is there a problem? I'm considering trading it it as I don't feel safe. It is an otherwise OK car.

My wifes 2011 Hyundai Sonata would not start yesterday at the clinic. I purchased a new battery went there today to replace the battery. Before I started the work I tried starting the car. When I turned the key to the on position the radio came on and the dashboard lit up like normal. As soon as I turned the key to start the car the battery went completely dead. The starter did not engage and the electrical went out.
I replaced the battery. When I turned the key to the on position nothing turned on. Not the radio or any of the dashboard lights. I tried starting the car and there was not response, exactly like a dead battery. I purchased a new battery and they tested it right in front of me before giving it to me so I feel like I can rule out the battery.
I double checked that he connections were tight. I tried jiggling the shifter, pushing the brake pedal, jigging the steering wheel around, jiggling the key in the ignition. The positive battery terminal connector has a fuse, it appears to be intact. I also checked the fuse panel in the engine compartment. All of the large fuses are intact (I only looked at the 3 or 4 of the large ones that were visible from the top). I didn't check the smaller fuses, I wasn't sure which ones to check.
A little background;For a couple days in a row my wife was noticing that the car was struggling to start (she didn't mention this to me right away). I noticed that when we were driving it the head lights had a very suttle flicker. When were idling at a stoplight it appeared as if the lights were dimming and getting brighter rapidly. I noticed it from the reflection of a license plate and dismissed it as maybe just the wind causing the license plate on the car ahead of us to wobble. It was suttle and not very pronounced. Yesterday my wife went to the clinic and when she was leaving the car would not start. Someone try with jumper cables but she was not able to get it started. Even after letting it sit for 5 minutes before trying to start it.
My buddy thinks it's the ignition switch itself, but that sounds quite a bit beyond my capacity. I suspected that since the lights were fluttering/dimming that it was an alternator problem. Even if the alternator is bad wouldn't the car still run on a fresh battery?

Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.

This morning, while looking into why the front drive wouldn't engage, and moving the plastic cover over the battery out of the way to check for any vacuum issues, the positive battery post cable to the battery post moved. There was some fluctuation engine-wise. After I shut it off and tightened down the cable, re-started the truck, and continued looking for vacuum leaks, a few minutes later the truck died.
What's been done thus far, re-checked battery connections, checked in-line mini fuse-20amp, checked both mega fuses-power both sides of each, checked 10 amp #4 in cab fuse block, removed alternator and took for check-checked ok. Would there be something else that would trip if there was an abrupt dis-connect from the battery with the truck running?

Weeks ago, I was waiting for someone with my car idling and suddenly it just stalled. The battery power was still on but the engine died. When I restart it, it starts up but then dies after a few seconds. After trying 3-4 times it no longer starts. I had it towed to the repair shop and by the time they went to look at it, it started up just fine. A few days later I was driving (like 1 min from my house) and the car engine died, again the battery was still working. Power steering was gone. I coasted off the road and tried to start it--again it would start up and then die and then after a few tries it no longer starts. I had it brought to the repair shop. Again, it started fine for them but they changed out the battery just to see. I also had fuel cleaner put in the gas tank.
Just to be safe, I brought it to a dealer since my normal mechanic couldn't find anything. At the dealership they ran codes and didn't find any. They said that sometime the lines to the cams or crank get corroded but that mine looked fine. Since it wasn't doing it for them, they didn't have any other recommendations. Everything has been fine for the last few weeks and then I went to start my car last night. It started fine even though it's really cold and hasn't been driven in a few days. While I was scraping the car, I could hear the engine turn off. When I re-started it the same pattern happened--restarted the first few times and then died and then wouldn't even start. I don't even know what to do at this point since it only seems to happen close or at home and not for repair places.

Let me start by saying electrical is something I really have no knowledge of....(never used any kind of an elec meter and don't have one) simple, Pos-grd and fuse, NP. I really don't want to fry something in these expensive new seats w/my normal trial and mostly ERROR!
The 08 (drivers) seat has 4 wires in the input clip.
GRN-RED (heavy gauge)
BLK-PURP (heavy gauge
BLU-RED
BLK-WHT
and my 01 whip out of the floor has a 3 wire setup.
GRN (heavy gauge)
BLK (heavy gauge)
BRN-BLU
I can wire PS side seat from fuse box and ground it NP. It only has a 2 wire set-up in the new seat.

I just bought an 07 Hyundai Entourage (Kia Sedona clone) a little over a month ago. We had our first storm last week and my wife tried to use the washer fluid on the rear and it didn't work (it was below freezing). I looked at it and the front didn't work either (no noise from pump motor either). So I found out it has a pump for the front and one for the rear but they are on the same fuse. Checked the fuse and it was blown.
I thought maybe it was due to the fluid in the car freezing (no anti freeze fluid probably). Put the new fuse in, tried the front for about 5 seconds and it worked. Tried the rear for 5, it worked. Tried the front again, nothing. Tried the rear again nothing. Pulled the fuse again accept it wasn't blown. Put a couple of different fuses in. Nothing. I did this while it was above freezing...? could both pumps have burnt up at the same time? Is there any other fusible link between the motor and switch?

I have a 1962 ford falcon ranchero. The driver side brake light, goes out when brake pressure is applied, but is on when lights are fully on, but even then brake pressure is applied and goes out. Right brake light is fine. And turn signal on right works. But driver side back light goes out when brake pressure is put on and when turn signal is put for left side. Right makes a turn noise left side doesn't. I recently replaced the turn signal switch. So its brand new. But older wires every where else. No cuts anywhere on wires. Fine. And replaced the bulb also.

I own a 04 Grand Cherokee and have recently had problems with my passenger side brake light. Now the light itself does work under normal running light conditions, but when I go to press the brake pedal it doesn't engage the bright brake light. Drivers side works fine and so do all my other lights, I replaced the bulb to no avail, and am now currently looking into replacing the bulb socket.

2010 F-250 14,000 miles, gas engine with Knapheide utility bed. Tilt wheel has been kept in the up position from day 1.
The problem:
No rear brake lights.
No high mount brake light.
No rear turn signals.
No rear hazard flashing lights.
All trailer lights work.
All other truck lights work.
Things checked: Fuses all OK. Visual inspection of multi-function switch. Looks clean. Brake switch at brake pedal has power on one wire. Jumpered the other wire-no brake lights.
I need to haul my trailer and am nervous when I see a Savannah, GA metro police car.

2012 Elantra - 105,000 miles 6 speed transmission
Throttle seems to be sticking and causing engine to rev between shifts, and staying slightly on after I let off the gas
Engine continues to rev up uncontrollably for about 10 seconds after feathering the gas pedal (between shifts). If I floor the gas pedal and release it quickly, it closes the throttle and fixes the issue.
Thought it may be a sticky throttle body, sprayed a generous amount of Carb and Choke cleaner into throttle body...did NOT resolve the issue. Its a Drive by wire, so no throttle cable to blame or to clean.
Turns out, the accelerator pedal assembly it self, is not returning/springing back to "up" or closed position and is sticking during the first few degrees of travel. It is very dirty, and gold.
How to clean/lubricate this thing? Its plastic. Or should I just order the replacement? I hope the pedal isn't programmed to the car itself? shouldn't be...but you never know

I've noticed when encountering a moderate hill at 60 mph in cruise the revs might suddenly increase from 2200 to 2700 rpm, then back down slowly as I crest the hill. If I'm in manual mode it stays in 6th gear, but almost feels like a downshift. I also feel no accelerator pedal movement. Is this a two stage intake at work?

My brake lights don't work. Turn signals, tail lights, hazard flashers work, but if I hit the brake, nothing happens. What could possibly be the problem? Could there be a wiring issue?

I did lower the steering column, onto the seat. Also lowed the dash and the wiring. Does it sound like the Multifunction switch could be bad? I can put it in drive, so I don't think it's the brake light pedal switch, that's bad.

I discovered today that I have no brake lights on my '02 Excursion. The center brake light works fine, but the two in the taillights don't come on. Stopped and bought new bulbs on the way home and replaced both, but the ones I pulled out were not blown. Checked the fuse - OK. Taillights and turn signals both work fine.
