2011 Kia Ray Problems: 2 Issues Every Owner Should Know

2011 Kia Ray Problems: 2 Issues Every Owner Should Know | Au7o

On the 2011-2012 Kia Ray, kia ran a public free-repair campaign (무상수리) in July 2012 covering 11,439 Rays built between November 28, 2011 and May 25, 2012 that were equipped with full automatic temperature control (FATC). A logic error between the ECU and the automatic climate control system could destabilize engine RPM — or stall the engine outright — when the driver braked while coasting with the air conditioning running and no throttle applied. The condition typically appeared at low speed in stop-and-go driving, exactly when an unexpected stall is most disruptive.

Common Symptoms

Engine RPM fluctuates when braking with the A/C on
Engine stalls while coasting to a stop in traffic
Idle becomes unstable at low speed with the compressor engaged
Problem only occurs when air conditioning is running

How to Fix

Kia reprogrammed both the ECU and the automatic temperature control unit free of charge at its service centers starting July 9, 2012. Any remaining unrepaired early-build Ray should receive the updated ECU/FATC calibration; used-car buyers should confirm the campaign was performed.

Typical repair cost:$0 - $0

On the 2011-2013 Kia Ray, rays built through roughly 2013 came with a solid (fixed) alternator pulley instead of an overrunning alternator pulley (OAP)/auto-tensioner arrangement. As the serpentine belt stretches with age, it slips on the solid pulley and produces a distinctive high-pitched chirping that Korean owners universally describe as a 'cricket noise' (귀뚜라미 소리), most noticeable during acceleration or when the A/C compressor loads the belt. It is one of the best-known quirks of early Rays in the Korean owner community. The noise itself is benign, but a badly slipping belt accelerates belt and bearing wear and can eventually affect charging.

Common Symptoms

High-pitched chirping or squealing like a cricket from the engine bay
Noise worsens during acceleration
Noise appears or gets louder when the A/C is switched on
Noise changes with engine RPM, not road speed

How to Fix

Replace the solid alternator pulley with the updated OAP-type pulley along with a new serpentine belt (roughly 200,000–500,000 KRW in Korea depending on whether alternator bearings are also replaced). On 2013+ cars with the updated pulley the noise is far less common; a belt dressing or tension adjustment is only a temporary fix.

Typical repair cost:$150 - $380
