  • 58,000 miles


The contact owns a 2005 Hyundai Sonata. The contact was informed that the brake lights were illuminated without the brake pedal being depressed. The contact stated that the battery had to be disconnected in order for the brake lights to turn off. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure and stated that the VIN was not included in NHTSA campaign number: 09V280000 (exterior lighting). The failure mileage was approximately 58,000.

Electrical issues began a month after driving the vehicle. Front and rear light bulbs continue requiring replacement, the dash light also will flash when brakes are depressed. The trunk leaked the first christmas, dealer claimed to repair it, but failed, still leaks. Air bag indicator came on, went off eventually, and is back on again. Finally, car began losing power last year and cutting off sporadically in traffic, and now the rear and window brake lights remain on when lights are on but not when turned off. Recall info points to defective stop brake switch that failed even after repair/replacement, however, my VIN does not appear on the recall list and the dealer will not repair or replace. Curious, since my car is of the make, model, and year reported! greedy and irresponsible !

This is the first date that I reported to the dealer that the air bag light was on. Since that time, the light has gone off and come back on a many times. It was checked again by the dealer and also by a local, certified mechanic. It usually stays off for about 6 months, but comes back on. It is now on again. In addition, I've had to replace the door jam switch in Jan. 2014. The door chimes (seatbelt sound) goes off randomly. Now, this sound is back. The car randomly locks itself and the radio randomly goes on as well. I feel that the car has electrical problems that may make it unsafe. I am especially concerned about the air bag issue. The car has approximately 57,000 miles on it. I find it hard to believe that this vehicle hasn't been recalled for any number of reasons.

Your probe into the Hyundai Sonata airbag issue should be expanded to earlier models as we have a 2005 and what you are initially explaining affects our vehicle also. We have had the airbag light reset a few times by the dealer (zimbrik Hyundai in madison, wi). They initially stated that it was just a wire under the seat that needed to be reattached. They'd do that and turn off the airbag light, it'd be ok for a few months, then the light would come back on. They eventually stated they wanted to repack the airbag for thousands of dollars, seemed somewhat like a scam, so we no longer go it fixed and have been driving with the airbag light on.

There is an electrical problem in my auto, which manifest itself when I switch on the electrical system. My headlights would come on normally, but inside the cabin the dashboard and all the other lights would start blinking on/off like the hazard light. The power door locks would also come unlock and when I checked on the external lights, the headlights would be steady, but the indicator (amber) lights and brake lights would be blinking. I have taken the car to a dealer but they were unable to diagnose the problem, because as they say, there are no diagnostic codes showing for electrical faults. I would appreciate any help you can give. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The 2005 Hyundai Sonata gls has several problems that should be under warranty and recalled, close to the 2006 recalls. We own a company and have purchased over 12 to 14 Hyundai. We have found that the Sonata gls 2005 has problems with the airbag deployment, seatbelt restraint, the front tires are closer to the back & not centered on the wheel well (has been this way since purchased, but they do not correct.), have electrical problems & that unibody type frame & so on. In an accident where a truck left the tail gate down & a ladder hit the windshield, the car was then parked, turned off, the keys taking out of the ignition & then began looking for the cell phone then proceeded to open the door to get out infer all that the driver's side airbag deployed which also caused the front driver's seat belt to lock up & can not be pulled out to wear. Hyundai states that this is not warranted even though it was deployed after the accident occured. Hyundai had a great warranty 10 years ago. They do not stand up to their warranty as before & I have found that some of the warranty has changed. I have switched to Toyota. Hyundai has done nothing so far to correct.

The contact owns a 2005 Hyundai Sonata. When it rains, water enters into the vehicle and collects on the step plates. As a result, the screws have rusted. The contact stated that the paint has removed from her vehicle in three different places. She also stated that the steering wheel cover has detached and her door is experiencing electrical failure. If someone were to lean against the door, all of the interior lights would illuminate. The dealer had to change the switch inside the door. The contact stated that the hood smashes the headlights and also contains a gap. The vehicle fails to start intermittently and the turn signals and interior lights on the instrument panel illuminate due to electrical failure. The dealer does not know why all of the failures are occurring. The current mileage was 26,000 and failure mileage was 22,000. Updated 02-01-08 the consumer stated no one is able to inform her about the defect due to the fact the vehicle being in hurricane katrina. The consumer stated the vehicle's windshield has been replaced but to no avail. Updated 02/01/08
