2006 Hyundai Elantra Problems

What owners report

Owners of this model year most often write about brake lights that stop working or stay lit, and about the airbag warning light staying on or the passenger seat sensor misbehaving. Brake complaints describe weak or noisy stopping, and a smaller group reports lamp, throttle and rust problems. Reports in the sample cluster between roughly 40,000 and 155,000 miles, so many of these issues show up on higher-mileage cars.

1. 1
   Exterior lighting

   Brake lights don't come on (stop lamp switch)

   • 43 complaints (28%)
   • median 83,450 mi at 7.2 yrs old (37 state mileage)
   • filed 2009–2020

   Owners describe pressing the brake pedal and getting no brake lights, or sometimes lights that stay lit after the pedal is released. Several say fuses and bulbs were checked or replaced with no change, and that a mechanic traced it to the stop lamp switch. Some owners say the dealer told them their VIN was not covered by a stop lamp switch recall, while others report the switch was replaced at their own expense; in a few cases the same switch problem kept the car from starting or kept cruise control engaged when braking. Reported from about 40,000 to 155,000 miles, most commonly between roughly 60,000 and 110,000 miles.

   Recall 09V2800001 related service bulletin

   What to check: With the key on, have someone watch the rear lamps while you press and release the pedal, and check that the lights go fully out afterwards. Ask whether the stop lamp switch has been replaced and whether the car was included in campaign 09V280000.

   2 excerpts from owner complaints in NHTSA records

   “My passenger occupancy sensor no longer detects the presence of a passenger, so my passenger airbag is always on, when the seat is both occupied or unoccupied. Also, my brake light switch no longer works, so my brake lights do not turn on when I depress the brake pedal. Both of these issues occur incessantly.”

   NHTSA complaint #11074662, filed 2018-02, 155,000 miles

   “I have no brake lights in my 2006 Hyundai Elantra which I just discovered. I replaced the fuses but problem was not corrected. While researching the internet, came across a notification that the brake light switch in these models are being recalled. I called consumers affairs with Hyundai and was referred to local dealership. Today, 5/12 went to the new port richey Hyundai dealer and was told by the service rep there is no recall and all of this was internet garbage. I left with no brake lights. …”

   Air bags

   Airbag light on / passenger seat sensor trouble

   • 55 complaints (35%)
   • median 68,000 mi at 6.0 yrs old (42 state mileage)
   • 18 mention a crash, fire or injury
   • owner-quoted repair $1,400 (median of 7 quotes)
   • filed 2006–2021

   Complaints describe the airbag warning light coming on and staying on, or the passenger airbag indicator behaving incorrectly whether or not someone is in the seat. Owners say dealers diagnosed a seat mat or occupant sensor and quoted several hundred dollars or more, sometimes noting a changed sensor connector design that requires an extra seat cushion part. A separate group reports airbags not deploying in a collision, including frontal impacts where the front end was heavily damaged. Reported from very low mileage up to about 170,000 miles, with many between roughly 35,000 and 105,000 miles.

   3 related service bulletins

   What to check: Turn the key to on and confirm the airbag light goes out after the bulb check, then watch the passenger indicator with the seat empty and occupied. Ask whether the occupant classification system was ever reprogrammed under the 2006 service bulletin.

   “Passenger airbag light in the center has never worked properly since I've gotten the car, the light never used to go off when an adult was sitting in the passenger seat which means the airbags were disabled. Now the dashboard airbag light has been illuminated constantly for about 6 months and does not ever go off, meaning all airbags are disabled. It came on upon starting up my vehicle and has not gone off since. …”

   NHTSA complaint #11129314, filed 2018-09, 103,000 miles

   “I was involved in a motor vehicle accident while driving my 2006 Hyundai Elantra. My vehicle speed was about 45-50 MPH and upon impact with the vehicle in front of me which was stopped caused my body to jolt forward and strike my steering wheel. I was wearing my seat belt which did not lock and my air bags did not deploy. Later on in the afternoon I had went to the er for chest pain, neck and back pain as well as injuring my right hand.”

   Brakes

   Brakes weak, noisy or slow to stop

   • 20 complaints (13%)
   • median 35,000 mi at 6.4 yrs old (18 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2007–2015

   Owners describe the pedal feeling soft or the car taking longer than expected to stop, and some mention a thump or clunk when braking. Several report grinding or dragging from the rear brakes, including a rear drum that could not be removed because the shoes had over-extended. Others say the dealer replaced rear brake parts at low mileage and called it a common condition on these cars. Reported from about 14,000 to 163,000 miles, with several under 90,000 miles.

   2 related service bulletins

   What to check: Ask for brake service records and have the rear brakes pulled and measured during a pre-purchase inspection, since a stuck or over-extended rear drum can be hard to spot from outside.

   “I am 5' 1 tall or short!! The sun was shining in my eyes and I needed the driver side visor down. It would not open so I had to apply a little pressure. The triangular clamp and the visor rod broke. I read that there have been several complaints in this regard but Hyundai refuses to replace it for free. The mileage is less than 60,000 miles.”

   NHTSA complaint #10454366, filed 2012-04, 38,000 miles

   “Dealership had to repair my rear brakes on my 2006 Hyundai Elantra at 14000 mi.. They said this was a common problem with elantras. If this is true maybe this is a problem that Hyundai should need to address. Maybe this could cause a braking problem down the road.”

   NHTSA complaint #10228055, filed 2008-05, 15,051 miles

Buying note. Check the brake lights and the airbag warning light before anything else, since those come up most often in owner reports. Ask for service records covering the stop lamp switch and the passenger seat sensor, and budget for brake work on a higher-mileage car.
