You can find out more about all the Kia Forte has to offer, as well as details about these common complaints, in the article below.

More about the Kia Forte

Kia’s five-passenger compact car, the Forte, made its debut in the North American market for the 2009 model year. As of 2020, the Forte remains in production and is a top-seller for the Kia brand.

All Kia Forte models are equipped with a standard four-cylinder engine and can seat five passengers.

However, specific features and trim levels can vary from one model year to the next.

The 2010 Forte, a popular model, comes in three trim configurations with standard equipment, including Bluetooth® connectivity, a four-speaker sound system and 15-inch steel wheels.

Meanwhile, the range-topping SX trim boasts such features as larger 17-inch alloy wheels, a leather-wrapped steering wheel and shifter, exclusive cloth upholstery, and a sport-tuned suspension for a more composed ride.

Common Kia Forte Problems

2010 Kia Forte: Engine Knocking Sounds

NHTSA Complaint IDs: 11351648, 11302387

There have been a number of complaints about the 2010 Kia Forte’s engine. Specifically, these complaints are related to strange “knocking” noises that come from the engine while it is running.

In one NHTSA complaint posted in August of 2020, the owner of a 2010 Forte reported that the motor had been making strange noises for a “period of time.”

However, on the date of this particular incident, the vehicle’s engine stalled out in the road. Even after getting the engine re-started, the owner reported a persistent knocking sound.

In another NHTSA report from January of 2020, another 2010 Kia Forte problem involved the vehicle making a knocking sound while running after it was taken in for a scheduled oil change.

Upon taking the vehicle back to the dealer for inspection, metal shavings were found in the engine, and the owner was told the engine needed a $6,000 replacement.

2011 Kia Forte: Overheating Exterior Lights and Bulbs

NHTSA Complaint IDs: 11075198, 11171813, 11256490

Another troubling complaint that seems to affect the 2011 Kia Forte is related to its exterior lighting. Specifically, it seems that the rear bulbs and brake light bulbs can become overheated and, in some cases, burn out frequently.

In one 2018 NHTSA complaint, an owner claimed that the vehicle frequently needed its brake lights replaced and that the component in which the bulb is plugged became extremely hot, sometimes to the point of melting and causing the bulb to burn out.

In another NHTSA complaint posted in 2019, a Kia Forte owner reported that the brake light bulbs on the vehicle were “burning out every three weeks,” and that the plastic bulb connectors were getting “very, very hot.”

2014 Kia Forte: Airbag Light Illuminating

NHTSA Complaint IDs: 11352871, 11353495, 11352425

Car Airbag Warning Light On The Dashboard

Numerous NHTSA complaints bring up potential issues with the 2014 Kia Forte’s airbag system. Namely, the issue seems to be that the airbag warning light illuminates for seemingly no reason.

In a complaint filed with the NHTSA in September of 2020, the owner of one 2014 Forte reported that the airbag light on the vehicle frequently came on, shut off, and came back on again. However, there is no mention in the report as to whether the vehicle was checked out by a dealer.

Another NHTSA report (also from 2020) mentioned that the vehicle’s airbag light stayed on even though no error codes were found. The owner of this Kia believed that the issue was a defective clock spring based on online research, but had not had this diagnosis confirmed by a mechanic.

2017 Kia Forte: Rough Engine Operation

NHTSA Complaint IDs: 11349949, 11350053

Even the newer 2017 Kia Forte model does not seem to be immune to complaints. One of the most common complaints with this model year is related to the engine running roughly.

In one 2020 complaint filed with the NHTSA, the owner of a 2017 Forte reported that the vehicle was brought to the dealer multiple times for engine issues. Specifically, the engine began to shake while the vehicle was in motion, and in some cases, the engine then stalled. The dealer was not able to diagnose or repair the issue.

Another owner reported earlier in 2020 that his or her 2017 Kia Forte was having similar engine problems issues, with rough idling and rough gear shifting the main problems reported. Upon taking it to a dealer on two separate occasions, the mechanics were unable to duplicate the issue or determine the cause.

According to Vehicle History reviewer Joseph Mckey, these engine problems are caused by faulty ignition coils.

Brake light sockets inferior
What ever plastic the manufacturer is using for the brake light bulb need to look at another material to be used . My brakes lights stop working especially after sitting in traffic when your foot is constantly applying the brakes. This constant brake use causes the hot bulb to melt the plastic causing it loses contact with the metal bulb contacts in the plastic sockets . Gone through three sets of brake light sockets so far every one was melted at where the bulb tongs sit in the socket . Changed to LED bulbs seem to have gone away but now my radio gets static when applying the brakes.

Title: Continued rattling noise in engine 2011 KIA Forte EX 2.0L
When I first got it 2 years ago I had to tear the engine down and have the Head rebuilt because of its repeated engine overheating. Afterwards I've replaced sparkplugs twice and also the ignition coils. Had to replace map sensor twice and had to replace brake light sockets twice because of overheating. Now use plus grade fuel to optimize gas mileage. Runs great other than the rattle noise while idle.

Most important
When I brought my kia forte 2019 I was told to keep the transmission under 3 otherwise i would have a lot of trouble with the car. I have done that and the run has run like a dream. Great gas milage 30 or better even in the city Hwy anywhere from 43 to 50 miles to the gallon. You just have to know about the cars before you buy them.

A cute car with pep
I saved a 2011 Kia Forte from another owner' s abject neglect in 2018. Properly maintained, this little car will give you joy even with it's quirk of the ticking engine. The seats are comfy.The controls make sense. It is spacious inside and stylish on the outside. Parts are cheap. We have loved it.

Engine makes noises and brake lights wont cut off
When I purchased my 2015 Kia Forte is was wonderful at first. Then out of nowhere the engine started making some rocking sounds and then the brake lights refused to cut off. Change the switch for the lights n now they sometimes blink like christmas lights.
