If there has not been a 'key on' ' key off' cycle with the right front passenger seat empty prior to installation of the crs.
Risk
The possibility of misclassification of a crs as an adult may allow the right front airbag or side impact airbag to deploy in a crash and could result in injury to the right front occupant.
Remedy
Dealers will reprogram the vehicle's ocs electronic control unit (ecu) to remove the feature that may cause the crs to be recognized as an adult. The recall began on november 15, 2005. Owners may contact hyundai of puerto rico at 1‑800‑981‑0188.

Rapid rusting of rear subframe cross member. Car rarely gets driven in snow or even bad weather. Went from minimal signs of rust to looking pretty rotted within the past year. Saw recalls on similar Hyundai vehicles. Maybe possible the same steel was used, or same lack of corrosion preventative.

Srs (airbag) service reminder indicator came on. I went to an auto parts store and they ran an obdii report on a bosch scanner. A b1448 oc (occupant classification) - passenger sensor mat defect came back. This is the same problem that the 2006-2008 hyundai sonatas have a recall on. The front passenger seat sensor, to detect a child seat or adult in the seat, may recognize a small adult as a child seat. If this happens and the front passenger air bag is deactivated, the risk of injury in a crash may be increased. I went to hyundai motor america headquarters in fountain valley, california at 3:45 on january 17, 2019 and left my contact information on a card at the front desk regarding this problem. I was told that I would be contacted but to date have had no reply from hma. The federal safety agency campaign id number 08v161000 as this presents the same danger to elantra occupants as the sonata recall, hyundai should be required to offer the same repair extension (15 years) as the sonata has.

Tl* the contact owns a 2004 hyundai elantra. While driving various speeds, the throttle positioning sensor failed on more than one occasion. Upon deceleration, the vehicle accelerated without warning. The contact depressed the brake pedal and the vehicle accelerated rapidly. In addition, the contact described the brake pedal as having a "dead spot", thus the vehicle accelerated on its own after the brake pedal was depressed. On one occasion, there was an increase in the rmps that was directly related to the worn position sensor. The contact independently replaced the positioning sensor. Millennium hyundai (265 north franklin st, hempstead, ny 11550) was made aware of the failure and acknowledged the failures. The vehicle was not diagnosed. The manufacturer was made aware of the failures. The failure mileage was 105,000.

Any assistance with this company will be much appreciated and to be clear there is a active air bag light on with a code the relates to occupancy detection for passanger front and side air bags

The antilock machine is locking the wheels so much that stops the car completely right in the midle of the traffic and the tires smell like burning tires. I had the car towed twice. I am so afraid that this happens while driving in the highway, that I do not drive there, only the streets.

I went to get a safety check and they told me that I couldn't get it because my air bag light was on. I live on a isolated island that doesn't have a hyundai dealership and the car dealership where I bought the car isn't giving me a call back while in the mean time I am riding around with a expired safety check and is fearful of getting cited.

Air bag light is on. This car should be under the 15 year extended warranty for this problem. The hyundai dealer will not look at the car without a fee.
