severe NHTSA 17V007000 January 6, 2017

Kia Motors America (Kia) has recalled one 2016 Optima vehicle

In the event of a crash, an air bag that does not inflate fully increases the risk of injury.

Fix: The affected vehicle was remedied on January 10, 2017. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC143.
critical NHTSA 16V231000 April 21, 2016

Kia Motors America (Kia) is recalling certain model year 2016 Kia Optima vehicles manufactured November 10, 2015, to February 12, 2016

If the second stage air bag does not deploy it increases the risk of injury or death.

Fix: Kia will notify owners, and dealers will replace the driver's frontal air bag module, free of charge. The recall began on May 6, 2016. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC131.

The failure pattern owners describe

Buyer takeaway: This model has documented patterns of airbag non-deployment in real collisions and unexplained dashboard cracks over airbag modules that dealers won't diagnose under warranty. Check the dashboard carefully, confirm recall work was completed, and get a pre-purchase inspection focused on airbag system integrity.

Owners report airbags failed to deploy in frontal, rear-end, and head-on collisions at impact speeds of 15–49 mph, with some incidents resulting in serious injury. One fatal case involved an owner filing recall numbers (16V7050000, 16V231000) and claiming the manufacturer refused to honor them. Several owners sustained facial, head, and torso injuries when airbags did not cushion impact, and at least one accident resulted in a fatality. In one rear-end collision at 49 mph, the passenger seat detached from its hinge while airbags failed to deploy simultaneously.

A separate, widespread issue involves spontaneous dashboard cracking directly above or along the outline of airbag modules—approximately 4-inch straight-line cracks on driver and passenger sides that owners report seeing in online forums across the model population. Owners note vehicles were stored in climate-controlled garages with minimal sun exposure when cracks appeared, and dealers have refused warranty coverage, claiming the damage falls outside warranty or demanding diagnostic fees without confirming any safety impact.

One owner reported complete airbag module electrical failure that disabled multiple dependent safety systems (blind spot warning, auto-hold, adaptive cruise control, lane departure warning, automatic emergency braking) simultaneously. The cascading system failure required module replacement.

Failure modes owners describe

Airbag non-deployment in frontal and rear-end collisions

Airbags failed to deploy or partially deployed in multiple collision scenarios (frontal, rear-end, head-on impacts). Owners reported crash impacts ranging from 15–49 mph with no or incomplete airbag response despite impact severity, resulting in serious injuries.

When: During collisions at various mileages; one reported at 42,000 miles, another at 34,202 miles

Symptoms owners cite: No airbag deployment in frontal collisions; No airbag deployment in rear-end collisions; Partial airbag deployment (steering wheel deployed but not front passenger; side curtain failed); Airbag sensor separation upon impact damage

Codes mentioned: 16V7050000, 16V231000

Repairs/costs cited: Recalls issued (16V7050000, 16V231000) but owners report manufacturer failed to honor or perform recalls. One vehicle was sent to independent mechanic and deemed destroyed.

Recalls/TSBs owners mention: Recalls 16V7050000 and 16V231000 issued; however, owner allegations include manufacturer refusal to honor recalls, failure to inform owners of defects, and claim that airbag 'was not meant to deploy' in one fatal case.

Dashboard crack along airbag outline

Straight-line cracks (approximately 4 inches long) appearing spontaneously on the dashboard directly above or along the outline of both driver and passenger airbag modules. Cracks described as clean slits forming squares around airbag placement. Owners report the vehicle stored in garage with minimal sun exposure, yet cracks appeared suddenly.

When: Multiple reports on vehicles purchased new in 2016; cracks appeared after purchase with no specific mileage correlation

Symptoms owners cite: 4-inch straight-line crack on dashboard above driver airbag; Clean slit on dashboard along passenger airbag outline forming square pattern; Cracks appear spontaneously despite vehicle storage in garage; Multiple identical complaints across owner forums

Repairs/costs cited: Dealers refused warranty coverage for crack repair, quoting warranty exclusion. One owner reported dealership demanded diagnostic fee without confirming if crack affects airbag function.

Recalls/TSBs owners mention: No recalls issued for dashboard cracking. Dealers declined warranty coverage citing non-warranty condition.

Airbag module electrical failure

Airbag control module malfunction disabling the airbag system and cascading failures across multiple vehicle safety and driver-assistance systems. Owner reported replacement was necessary.

When: Occurred at unspecified mileage

Symptoms owners cite: Multiple warning lights illuminating simultaneously (passenger airbag warning, blind spot warning, auto-hold, adaptive cruise, AEB, lane departure); Loss of communication between airbag module and other vehicle systems; Complete system malfunction requiring module replacement

Repairs/costs cited: Airbag module replacement performed at dealership; no cost information provided by owner.

Passenger seat hinge failure and airbag non-deployment

Front passenger seat detached from hinge during rear-end collision while airbags simultaneously failed to deploy. Vehicle sustained $10,000+ in damage and was deemed a total loss.

When: At approximately 42,000 miles during collision

Symptoms owners cite: Passenger seat separation from hinge upon impact; Airbag non-deployment during 49 mph rear-end collision; Multiple injuries to driver and passenger

Repairs/costs cited: Vehicle towed to independent mechanic who declared it total loss. Airbag sensor partly separated in collision damage.

Recalls/TSBs owners mention: Manufacturer instructed owner not to allow vehicle inspection by third parties and dispatched investigator to perform inspection.
