Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

While driving, the damper pulley seperates and the power steering fails along with the water pump and the alternator. This damper as it is called is a device that drives all the belt powered devices on the engine. I asked the dealer if there was a recall on this and the reply was no. How can a power steering failure not be a recall? when you are turning and the power steering fails I would say the majority of drivers would not be able to steer the vehicle out of this situation. Look online and view all the places that list this problem. This is a big safety issue the vehicle steers very hard and is difficult to control.

My Sonata 3.3L V-6 engine with what appears to be a very common and dangerous problem. This vehicle seems to begin stalling and slamming into 3rd gear fail safe mode, luckily I have not been rear-ended due to this yet! I have read up extensively on this and found many with the same complaint on website. It appears many dealerships are aware as they have had vehicle in to be problem solved with what appears to be an electrical problem more so than a mechanical problem. After having my car into 4 different shops including a dealership the first time it happened with no fix and only a ¿if we can¿T replicate the problem we can¿T fix it¿ response I get mad. We have ruled out everything possible; transmission, engine, relays, etc. For 4 months it has been in and out of shops trying to diagnose the problem. Which is happening so often now it is not safe and I am having to take out a loan to try and buy a new care. I cannot trade this in due to the problem. When it is running it runs great, until it slams into 3rd gear with no warming and you loose all acceleration or it dies completely. You can shut it off and restart it and it runs as if nothing happened, until it stalls again. The last mechanic having verified everything he was told to check has determined it must be in the computer. Some individuals said early on they had the computers replaces (at a big cost) only to have it happen again. My car is 10 years old and only has 118,000 miles on it. I hate having to get rid of this car but there is no way it is safe to drive in this condition. Hyundai seems to be ignoring this complaint as no recall has been issued and no help in repairing the problem. Too many cars at the aprx mileage with the same problem and leads me to believe a recall is in order or financial reimbursement for the months of repair to fix it should be made. Elaine huska

My 2006 Hyundai Sonata has a design problem. The cup holder is level and next-to the gear shifter. When I brake, occasionally fluid from a beverage may fall onto and into the gear shifter. The shifter enclosure allows fluid to flow into it and collect around a connector providing electrical signals that end-up communicating to the car's computer¿and then onto the transmission that I downshifted when I did not down shift. The result is I have to flip over to 'shiftrionic¿ mode because the car is performing like I put it in that mode when I did not. I try to upshift but it does not work properly¿I end up being distracted trying to put the car in the right gear and the car ends up going faster than I intended. I generally don¿T notice the downshift until the engine starts roaring¿.dropping into second gear especially on the highway is very unsettling. Again, I try to maintain my speed by pressing on the accelerator and attempting to upshift and it's very distracting. I have had a ¿plus 5¿ driver rating for over 2 decades and I own two other cars and I never been ticketed with either car. But I recently have been ticketed twice with the Sonata and in both cases the car down-shifted without my knowledge. The problem started sporadically about 2 years ago and initially I did not know the cause of the problem. It takes a little while for the beverage spill to create a shifter malfunction, so it's not obvious what is happening for a while. The problem is so common that there are videos on youtube to identify and address the issue. It is a simple but potentially dangerous design flaw.

The parking lights will automatically come on by itself when the car is off and there's no key in the ignition. I have returned to my car from work and the lights would be on draining the battery. In addition, while driving the parking lights will come on and go off as well as in the dash when the switch is in the off position. I have video but it's not downloading.

I own a 2006 Hyundai Sonata, at 100,000 (hwy miles) the front upper control arms became squeeky and detatched from the rubber bushings, making a horrible ride and clunking sound when I would put the car into gear. This problem makes the car bouncy and unstable. There is also a knocking or loud clicking sound in the engine at crusing speeds, when I barley push the gas pedal. It sounds like the air intake control valve. It goes away when I accelerate. The radio and cruise control electornics seem to work only when they want too!

Oil leak from engine valve cover - left (front) side of 3.3 V6. This is directly above alternator. Eventually alternator fails due to severe oil/dirt contamination. First noticed when battery light comes on at idle, showing charging problem. By then damage is done. Valve cover must be replaced along with alternator or problem will quickly recur. *there is currently a recall for Hyundai veracruz with same engine for the same problem. Sonata is not included, but a quick internet search shows this to be a common, well-known problem for many years.

Burning smell likely electrical appears to be coming from under the dash board. Car checked by mechanic all around exterior- not from any components there. Burning smell identified by mechanic as electrical likely plastic insulation that is burning. Only electrical work done was by hyudai recall to correct air bag warning light that airbags were not operational specifically the defect was to have necessitated removing the passenger seat and fixing/replacing a sensor. Since that was corrected the inside light does not go on when the car door opens. The burning smell comes on after the car has warmed up -been running ten-15 minutes. So far no other effects. I had hoped the burning smell would go away. Today is three weeks and burning smell has not diminished forcing me to open windows to vent while driving. Now I must make a appointment to have the dashboard removed to locate defect.

This Sonata had electric problems from the very beginning (climate control, light bulbs, brake lights, side mirror control, window control, cabin lights, etc.). most of the light bulbs have been replaced many times either by the dealer when it was still covered by warranty or by myself. The most recent round of replacement was on July 3 for the passenger side headlight, driver's side turn light (yellow) and rear left back off light. I finally started to question if the fuses were misplaced. After checking carefully the fuse types and labeled specifications of both the engine and cabin fuse panels, I found three fuses in the cabin panel were not the same as the owner's manual described. They are (wrong fuses in the parentheses): FS19 20A (25A), FS6 10A (15A), and FS5 25A (20A). I rearranged all three fuses according to the specification on the owner's manual (P. 6-41). Hyundai should be legally and financially responsible for these problems, which occurred during the assembly but led to countless frustrations and even safety problems when those lights were down frequently.

I turned on ignition and, as usual, all dash lights came on then disappeared, as usual. However, the "passenger air bag off" light returned on and the warning chimes have been ringing ever since.if a passenger sits on the passenger seat then the light stays off. Jiggling of wires underneath the seat do not fix the problem.

This is the second repair of buckle assy- front (first repair was performed in 2009). I paid for the second repair on 6/25/14 as the maintenance manager said it was a one-time recall and would not be covered under warranty. (part: 88840-0A000-qs) needed it done for safety so I paid; but, it bothered me that it was a recall and I had paid nearly $260. I called the dealership after the first of the year (2015) and after talking to a couple of people found there was an extended warranty that should cover the cost. After numerous calls, mailing invoice with check number, faxing same on 3/20/15, I got a phone call today requiring me to upload a file to a particular website. I called and went thru 2 more people, one of whom had my hard copy invoice document in hand, could not enter my personal info. (phone #, address, email address) and, was not in the dept. That handled the "campaign" refund; she transferred me to "sweetie" who still insisted I must create a jpg file of my invoice to post to the new website. (I am 62 but figured it out, others won't. I have doggedly pursued my refund but Hyundai is making it nearly impossible (which I told them). Today is 4/20/15. Waiting for next ridiculous requirement. Too many phone numbers and websites to list here. Also had valve cover oil leak repaired on 6/25/14 and based on a complaint seen on this site, I am waiting for a second occurrence. Installed 22453-3C110 gasket-rocker cover LH, replaced valve cover gasket. We can complain all day but nobody is streamlining the recall repair process. At least I finally discovered this website which I am saving to favorites.

Driving on my way to an early lab appointment 645 am. When I got about 2 miles from destination doing 40 mph, when the check engine light came on. Followed by the ESC light, battery light, airbag light, seatbelt light blinking, and lights on dash dimming., when I stopped at the traffic light, the speed odometer still read 40. When light turned green, I went to step on gas, and car would hardly move, I was able to get off road safely. I turned car off, dead. I walked from where I left car, to appointment almost 2 miles each way.I am a heart patient[ have an artificial valve and a defibrillator\ and this episode upset me. I read today, that this happens to Hyundai Sonatas. When I got back to the vehicle, I arranged it to be towed to a mechanic. Is there a recall on this, if so we have never received one, this vehicle has been owned by us since 2009.

Under regular driving conditions the brake pedal would become so hard that they could not be pressed down, the speed would decline to 5 miles per hour and the car would start smoking. The ABS and ESC light would come and wouldn't go off until car is turned off. This S due to a faulty ABS hecu unit (hydraulic and electronic control unit) and the right front upper control arm. I contacted Hyundai who wouldn't pay the dealer to fix my 2006 Hyundai Sonata gls V6 with 65,263 miles. They advised that the isn't under warranty, however, the ABS hecu unit is faulty. This is a safety concern for myself and fellow drivers.

Oil leaked from valve cover onto alternator. Engine stalled and left me stranded on rural mountain road. Finally got towed home. Mechanic says it will cost nearly $1000 to replace valve cover gaskets and alternator. Car is 2006 Hyundai Sonata with 3.3L 6cyl engine. I believe that this is the same engine and same problem that prompted the recall on 2007 Hyundai veracruz NHTSA campaign number: 14V415000. The existing recall should be expanded to include more Hyundai vehicle models that exhibit the same problem.

The system warning lamps illuminated, then the engine shut off and would not restart. Evaluation showed that the alternator had failed and was covered with engine oil which had leaked from the front valve cover gasket onto the alternator. This failure is the same as NHTSA campaign number 14V415000, which covers another Hyundai vehicle.

In 12/21/09 airbag system light kept coming on. Took it to the dealer. They stated chip related to air bag system under the passenger seat was broken and I was not covered under warranty. Invoice # [xxx] (dennis Hyundai of dublin) repairs estimated at $500 to $900. Called Hyundai with a complaint. The service manager then called we had a meeting. I paid $ $175.03 to replace the chip. They also repaired passenger seat per NHTSA recall 13V-354 (note the recall repair only worked for about a year). After the warranty expired I took the vehicle to both the dealer and local repair shops. The airbag light would come one and then sometimes when I stopped reset its self or the dealer/repair shop could reset the light. The electrical wiring system started to act up after the 60,000 mile warranty period expired. The ABS light comes on then goes off the radio will come in loud the get quiet. The constant however is the airbag system light. I had the seat belt (driver side) changed (twice) in 2011 as the first replacement in did not work. The airbag light was off for a short time and then came back on. It will not reset so the airbag light is always on. I have always felt this problem should be covered by Hyundai.

Airbag light is on and the authorized service centre diagnosed that it is the driver seat belt problem hence need to replace the seat belt for around $500. When I searched on internet I found that this is the factory problem hence I think it should be company recalled and should be fix for free.
