Hyundai Sonata owners have reported 27 problems related to alternator/generator/regulator (under the electrical system category).
The contact owns a 2006 Hyundai Sonata. While driving the vehicle, the contact heard an abnormal noise. The vehicle was taken to an independent mechanic who stated that the drive gasket was leaking onto the alternator and the alternator needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact referenced NHTSA campaign number: 14v415000 (engine and engine cooling); however, the VIN was not included. The failure mileage was 59,158. The VIN was not provided.

While driving the seat belt light came on. About a minute later the radio shut off. Next most of the dash lights came on , the engine would not make power/accelerate, and the braking seemed weak/jerky. Pulled into a parking lot as soon as I could. Now all dash lights were on/blinking and the radio, sunroof, windows etc would not work. Thinking it was an electrical issue I left it running to investigate. Next thing I know the car is overheating even though the gauge isn't showing it. Steam everywhere and the overflow popped the cap off. Shut the car off. Once the car cooled I was able to see what happened. Oil has been dripping on to the alternator from a leak in the valve cover gasket. This killed the alternator which in turn caused the control/braking/acceleration issues one it was on battery only. I'm assuming the fan was not cooling either which resulted in the overheating.

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.
Intermittent flashing and blinking dashboard and exterior light while turn signal or wipers are engaged after this incident happens the battery is drained of power. Battery test full load and alternator test good. The battery is wearing down because of this malfunctioning electrical problem. Last night (8/21) something new happened. When I went to start the car I found it dead again; yet the " lights on" indicator light was visible on the dash buy the light switch was in the off position. I have others witness this crazy malfunction over the past 4 months and yet the Hyundai dealership cannot replicate the problem and therefore will not replace the combo switch (as diagnosed by my corner mechanic).

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.
Engine died while driving. The cause was alternator failure due to oil leak from front valve cover. This is a 2008 Hyundai Sonata 2008 with 3. 3 liters v6.
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.
The front valve cover gasket leaked oil down to my alternator, causing it to malfunction and making my transmission shift awkwardly.

I am reporting this because I see other models with the same engine having the same problem. My valve cover gasket leaked oil onto the alternator and caused it to fail prematurely. This has happened in April of 2014 and has now happened again in June of 2015. Other models utilizing the same engine have been recalled due to this problem. Will this model be recalled?.

My 2002 Hyundai Sonata radio comes on and off when ever it wants to and I notice when it rains it makes a really loud noise. I have to replace an alternator 3 times within the last 3 years. Not sure what could be causing this but it is very annoying. Please help!.

Headlights dim momentarily, radio goes off momentarily, passenger seat side kick panel relay goes "ticking" momentarily, car jerks momentarily when gas pedal is applied and gear is changed from 1 to 2 or 2 to 3 when I just start my journey (I. E. Just start the engine and start driving, usually). If gas pedal is released while any or all of these are happening, abs, brake and esc warning lights come on and stay on the dashboard. These warning lights remain on till the next time I start a new journey and will only go off if the problems mentioned above don't happen as the gear changes from 1 to 2 or 2 to 3. I've been to a Hyundai dealer countless number of times. Alternator and battery has been replaced. Ground wires have been checked. They have no clue what is wrong with the electrical system. Please fix this. It has been a known problem and still is creating problems for Hyundai Sonata owners.
Several times I have had the alternator and battery fail shortly after and during a rain fall. When it rains the electrical system starts given problems by turning lights off both outside and cluster panel lights, it also starts giving warning light failures such as abs, esc and the hazard lights will not function during this time of failure making it very dangerous to be run into in the dark of the night. The dealer is useless as all they do is put the VIN # in their computer and say there is no recall nor know problems as these problems and it is working fine after the alternator is replaced. The car was bought used and in less 10 months the car has had 3 alternators and 2 batteries and the problem has not been resolved.
I have a 2000 hyandai Sonata. I have had several sensors replaced in this car already. It is somthing electrical or another sensor, go figure. My wipers stopped working, and my wiper fluid pump also went out. Had local auto shop replace wiper fluid pump, they tried whatever they could, then the wipers would not stop working,so they took out the relay switch. Then my wipers start working and I can turn them off/on with out the relay switch in. My car power locks are not working either, which they did before. Then my car would not start for next three/four days, had to have it jumped each day. So I thought it was my battery or alternator, had those tested, it is not either of them. Then my car the next couple of day starts a little better, but still barely starting, and sometimes when I start my car, the power locks lock automatically. My radio has always acted up by turning off and on when it wants and not saving the stations I save everyday, but now it goes from a station to my cd turning on, just by itself. I have seen other complaints about this on the internet, there is seriously something wrong with the electrical wiring or the senors of this car, there needs to be a recall this could be real dangerous. You never know what is going to happen. Please help!.

When the brake was applied or excel pedal was not applied, all electricity function(radio, a/c, and headlight) went down for a second and came back again. It started happen when the vehicle marked over 100,000 miles and occurred frequently during driving. Even after changing battery and alternator which dealer pointed as reasons of the problem through whole electricity check-up, it happened again and again. The dealer couldn't point out the reason. I appear this problem here for serious potential accident possibility.
Electrical system outage including interior and exterior dimming lights, radio turns off/on, ac shuts off/on, dashboard lights come on and eventually turn on (engine, abs lights, etc. . . ). This occurs every time I drive my car, 4-5 times in a 10-15 minute drive. Usually happens at lower speeds, when decelerating/accelerating, but not consistently. Air bag light has been on for last 3 months. Air bag light issues couple yrs ago and took to dealer for recall issue, attributed to a sensor issue, which seemed to fix it until recently. Had alternator replaced 3 months ago, without improvement. 3 mechanics unable to identify cause. Very frustrated! otherwise car has done well. This should be recalled and fixed, as I've noticed many other similar complaints.
During cold starts battery & seat belt lights come on. Also, power steering seems to not work. This happened several times. The alternator & battery were replaced, but did not correct the problem. Dampener pulley replaced & corrected the problem.
After attempting to call Hyundai, I am absolutely fed up with everything they are doing. I have "repaired" my vehicle on numerous occasions to no avail. After at least 5, definitely more, trips to the mechanic I have repaired the alternator twice, the idle air control valve, brakes, motor mounts, done a transmission fluid change, and have had to repair 2 flywheels in the transmission. That list does not include the general maintenance of plugs, filters, and oil. I can't deal with this anymore. This is not actually my vehicle, this is my mothers vehicle, but regardless of who's vehicle it is, this is not acceptable. What it basically is doing is when it reaches a certain mileage it will basically "kick/jerk/push forward" (for a lack of terms) when it reaches 12 mph and 32 mph and I'm certain of others but my mother virtually never drives above 45 mph so anything above that I'm uncertain of. It also has a very hard time accelerating to 20 mph. Once it's above 20 mph it's easy and accelerates very fast. My mother has nearly been hit twice due to this inability to accelerate as fast as it should. I have taken it too Hyundai and they refused to look at the vehicle saying it is out of warranty, so I took it too numerous different mechanics. I am getting 3 different answers, something in the fuel/air line, engine computer module, and transmission. I do not want to have to pay for any of these repairs so I haven't done any of them, but I am thinking that this definitely needs to be reported. There are transmission and electrical items being reported which may be related to this. If this is as numerous as I'm seeing on here, you may want to issue a recall on this vehicle. Once is a coincidence, 5 times is phenomena, but over 20 times is an explicit failure by the company, no matter if the vehicle is 30 days old or 30 years old.

At first it was the radio, turning on and off by itself when I would try to lower the volume it would be louder. My headlights would go out and turn on again, my emergency brake light will turn on as my car would stop in the middle of the street. Air bag deployment sign is on and the bag it is not deployed. The abs, esc and other glow lights will turn on; sometimes I cant roll down the windows or lock the car with the button. Now my car will not start, no power and it resets my clock. I have gone to the dealership twice and they are greedy money hungry !@#$% who do not care for their customers, I replaced the battery and the alternator and its been through diagnostics and the alternator was the only thing found wrong. I have issues with the car at least twice a day and three times its died completely. This is an 2006 Hyundai Sonata it should not give me these problems.
Car stalls out in low speed driving, idling, and or when back up. I have been able to avoid an accident with passengers in the vehicle or not in the vehicle while I was driving. I have had oil changed, fluids checked, alternator changed, spark plugs and wires also checked. The car has also had fuel system flushed and problem with stalling persist.
The contact owns a 2006 Hyundai Sonata. While driving at night, the radio and the headlights shut off without warning. The dealer was able to duplicate the failure, but could not provide a remedy. They have inspected the vehicle on five different occasions. The following parts have been replaced: the alternator, fuse box, computer, electrical harness, and the battery. The failure continues to occur. The current mileage is 15,000 and failure mileage was 9,000.
After driving my car and shutting engine off for as little as five minutes the car would not start again. This has happen several times and it has been in the shop for repair eleven times. On one occasion my car lost power, engine died and would not start again. Car would have to be towed to the dealership. I have been through three alternators and one battery. They is a major electrical problem with the car. Hyundai will not replace this lemon. Car is in the shop now.

While driving at an undetermined speed, the battery light came on and the vehicle stalled. The problem was caused by alternator failure. The dealership indicated that there was a TSB for this issue. Houser dealership replaced the alternator with a different type and configuration. Another dealer replaced the battery, alternator and drive belt. All work was covered under warranty.
I had my bearings replaced, my rear hub bearings. Now it is making to same noise and they now say it is not the bearings-they do not know what it is! my car idle sounds like is going to stall all the time when I am stopped. The car pulls around 5,20 and 50 mph like it just cannot get gas or the transmission is bad. I brought it in 2xs. They say they do not know what it is and cannot get anything on the diag machines. Now I am passed 60,000 miles. After having my car for 2 days (giving me no lender or rental) they found a problem at the last minute. Oil leaked from the valves into the spark plug wires into the coil pack and that is the car pulling problem. They say I have to pay $600 to fix it. This was on June 6,2003. I brought the car in for the idle which was not fixed and brought it in for this engine hesitation 2xs. Both times they did not and couldnot fix these problems. I have the receipts that they could not fix nor repeat these problems, but they are noted. I should not have to pay for these repairs!!!! this is not daily upkeep!! this must be defect!! I have a real problem with this car! I need to be contacted on this matter for Hyundai to pay for these repairs! I am having a difficult time on this matter. These parts need to be replaced now and I cannot and shouldn't have to pay for these parts or labor! I also have had my front driver window regulator fixed 4 times, my front passenger side regulator fixed once, my rear regulator fixed once. I had to buy a new battery for my car and a new headlight in the first year(Hyundai said I had to submit paperwork to see if they would vote to repay me for my cost of the battery). I had my air bag light going off(which now I never trust for it to go off when needed or even go off when not ). My paint is chipping everywhere! my front passenger window leaks all over my carpet inside floor. And many more problems! thank you, darlene liddane dliddane@earthlink. Net 941-637-0802.

Collision occurs, acceleration continues, car spins out of control across two lanes and into a grassy field. I put it in park and shut off the ignition in order to stop the car from continuing into the fencepost. Patrolman said the throttle was open. Insurance company valued the vehicle a total loss. Recall campaign: the consumer could not slow down the vehicle. After impact the consumer stated that the engine was still racing and she was still pressing the brake. The emergency brake had to be pulled to stop the vehicle. The officer on the scene started the vehicle and the engine was still racing. Yhe battery and alternator were replaced.
Alternator went out which made the electrical system to go out. Entire dashboard was not working, also, abs brakes and engine check lights kept blinking. There was an electrical smell. Dealer replaced alternator.

The power-steering pump s leaking down into the alternator, and shorting it out. Dealer looked at it three times and replaced the high psi line going into the pump, as well as the crush washers. That was accomplished the second time it happened. The third time they replaced the high psi line again, and it occurred three more times and they told us there was nothing that they could do because the vehicle was out of warranty. Therefore we have replaced the alternator three more times to correct the problem. I, the owner, built a guard over the alternator to prevent the fluid from leaking into the alternator. Since then we have had no problems, but it took the engineering of myself to fix the problem.

When driving on the highway at 65 mph transmission stopped changing gears, causing vehicle to decelerate, and losing all power. Consumer has contacted dealer. Dealer replaced transmission. Also, having other problems with the starter and alternator. Axle broke , defrost malfunctions and cassette player failed.
