What is the 2011-2012 Kia Sedona Air Bag Control Unit May Short Circuit, Disabling Front Air Bags and Seat Belt Pretensioners?
Kia recalled 2011 and 2012 Sedona minivans because the air bag control unit (ACU) may short circuit during a crash. If that happens, the ACU cannot fire the frontal air bags or the seat belt pretensioners, so those restraints stay inactive in exactly the collision they exist for. Severity: high.
What is the 2011-2012 Kia Sedona Fuel Rail Heat-Induced Cracking and Fuel Leak (2011-2012)?
On 2011-2012 Sedona vans the fuel rail develops a small heat-induced crack from sustained under-hood temperature, leaking pressurized gasoline directly into the engine compartment. Kia recalled all 51,465 vans built 3 March 2010 through 14 August 2012 under NHTSA 20V-101 (Kia SC1… Repairs typically run $0-$0. Severity: high.
What is the 2006-2012 Kia Sedona Front Lower Control Arm Corrosion Fracture (Salt-Belt Recall, Twice Expanded)?
On 2006-2012 Sedona vans the front lower control arms corrode from prolonged road-salt exposure and can fracture at the arm body, dropping the front suspension and causing immediate loss of steering control. Kia recalled the vans twice: NHTSA 13V-550 (Kia SC133) in December 2013… Repairs typically run $0-$700. Severity: high.
What is the 2006-2014 Kia Sedona Power Sliding Door Cable Fraying and Failure?
The 2nd and 3rd generation Sedona (2006-2014) is notorious for power sliding door cable failures. The steel cable that drives the power sliding door frays and eventually snaps, leaving the door inoperable or stuck partially open. The cable routing puts excessive stress on the cab… Repairs typically run $200-$700. Severity: medium.
What is the 2002-2014 Kia Sedona Sliding Door Latch and Roller Mechanism Failure?
Sliding door upper and center rollers wear out, causing the door to bind, squeak, and become difficult to open or close. The latch mechanism also fails, preventing the door from fully closing or opening. Common on both manual and power door versions. Repairs typically run $150-$450. Severity: medium.
What is the 2002-2014 Kia Sedona Alternator Overheating and Premature Failure?
The alternator is positioned in a heat trap near the exhaust manifold, causing premature failure. The voltage regulator overheats, leading to undercharging or overcharging. Multiple alternator replacements within 100,000 miles are common. Repairs typically run $250-$500. Severity: medium.
What is the 2002-2014 Kia Sedona Front Bank Valve Cover Gasket Oil Leak That Soaks and Kills the Alternator?
On the Sedona V6 the alternator sits directly below the front cylinder bank. When the front valve cover gasket hardens and weeps — a routine age-and-heat failure on these engines — the oil drips straight down onto the alternator, saturating the windings and brushes and destroying… Repairs typically run $200-$900. Severity: medium.
What is the 2002-2021 Kia Sedona Rear A/C Line and Rear Evaporator Refrigerant Leaks Plus Compressor Clutch Coil Failure?
The Sedona carries both a front and a rear evaporator, and the rear circuit is what makes its A/C failures distinctive. Long refrigerant lines run the length of the van underneath the floor, where they corrode and leak; the rear evaporator and its O-ring connections are additiona… Repairs typically run $200-$1,600. Severity: medium.
What is the 2002-2014 Kia Sedona Front Wheel Hub Bearing Failure — Humming That Rises With Speed, Sometimes Total Hub Separation?
The Sedona is a heavy van on a passenger-car front hub, and front wheel bearings are one of its recognized weak points. Owners on the Kia forums report replacing three of four bearings on a single van, with the failure showing first as a hum or grind from one corner that gets lou… Repairs typically run $250-$700. Severity: medium.
