Sun visor will not stay in place, visibility obstructed and dangerous.

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.

My driver's side sun visor broke and cannot stay up. I have to put it to the side, but it blocks side view dangerously. This is a common defect for Sonata 2006-2008. The technician at the dealership noticed the problem, but never mentioned to me during warranty. Many complaints have been reported to Hyundai www.howtomendit.com/answers.php?id=157121, but Hyundai simply ignores it.

The safety labels on the visors have curled up and lost their adhesion to the visors making the labels unreadable. The vehicle was manufactured on 4/26/05. A NHTSA safety recall, campaign id no. 06V234000 was issued for this defect for vehicles built May 15, 2005 through August 2005. This recall was inadequate to include all affected vehicles. It should be expanded to include these earlier built vehicles.

Drivers side visor fails to stay in upright position and will fall to a position that can block the drivers visual field. This is apparently a common defect with this model of vehicle, but Hyundai fails to recognize the safety issue and will not repair or issue a recall.

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.

The sun visor of the drivers side recently fell and it won't stay up with the velcro stapled. It is very annoying and potentially dangerous while driving. It can obstruct my view and be distracting.

Dash board air bag light came on and remained on. Took to a mechanic who stated it was an error code that was not longer active. A sensor must have set it off, but there was no longer a problem. A few weeks later airbag light came on again. Took vehicle to Hyundai dealership who stated occupant classification system (OCS) or sensor that was part of system registered an error at some point in the past few days and that is why the light went on. They stated there was no longer an error, but that the sensor must be going bad and would need to be replaced before it failed. Reason being, once the sensor failed, the air bags (at least passenger air bag, potentially whole system shut off so driver as well?) wouldn't deploy in the case of an accident because system would shut off as a result of a sensor failure. Dealership stated that sensor could not be replaced individually, but that the whole passenger seat cushion would have to be replaced. The sensor is part of the OCS system. The quoted cost for the part (seat cushion with electronic sensing system) would be around $1500 total ($1350 for the part, $150 for the labor). As of now air bag light not on, sensor hasn't failed yet. Once it does, need to replace if want air bag system to deploy. This seems like a very serious safety issue that should be addressed by a recall. I have read hundreds of customer complaints online that have the 2006 Hyundai Sonata with this problem and haven't had it fixed. As a result there are a lot of people driving around in a vehicle that some if not all of the air bags won't deploy in (and most if not all of them don't realize it disables the air bag). This design flaw could result in serious injury or death. All information I received in regards to airbag light issue was from the service department at a Hyundai dealership. This issue needs to be investigated and a recall needs to be issued.
