Nov 2023 Fire

On 8/28/2022 my 2011 Kia Forte's engine caught on fire and it caused damage to my entire garage along with my personal belongings. I had contacted Kia multiple times and was put on hold for over an hour at a time and hung up on multiple times until a few weeks after the fire I finally got a hold of them and they put in a "work order". After following up with them a week later I come to find out that the work order was put in for a car pare (the engine in the car was burnt to crisp). I finally had someone help and a representative from Kia came out afterwards they conveyed that after "their investigation" that "evidence shows fire and heat attacking vehicle from outside and moving into the engine compartment". Which is completely false per fire department who where first on the scene they determined the fire started in the engine compartment of the vehicle". This was very disappointing Kia took no responsibility for this. Now I receive a recall notice dated November 14th, 2023 stating that "the Hydraulic electronic control unit may experience an electrical short circuit, which can result in an engine compartment fire while driving or parked. This is exactly what happened to my car at the time of the incident so now they are admitting they were at fault.

My daughters Kia Forte, started making a ticking noise. Them more she has driven the car, the worse the ticking has become. Looking on line to see what the problem may be, it appears that this is a very well known issues with Kia’s. Also reading on your sight there has been MANY complaints for the very same thing. If Kia has been made aware of the issue and did nothing about it. I feel that is negligible for them. My daughter travels out of state for college. I would hate for her to break down on the side of the road. Our mechanic said that we should use a certain type of oil of her car, her oil changes are done every 3,000 miles. They now coast us 70.00 each time we have to change the oil. I hope that you will investigate this issue with as many complaints that have been registered against Kia.

I have a 2011 Kia forte had 130,000 plus miles when I bought it. I've had the car for 1 year first 2 months motor sound it 100% 3rd month I started to hear a knocking sound coming from motor I took it to kia dealer today for recall service so I asked them if they could here the knocking sound they told me that the sound was normal. I told them that when I got the car it wasn't making this knocking sound and getting louder each month. They changed the conversation and told me that i was there for them to work on a recall matter for my car. i don't know what it could be maybe the engine pistons idk but I have read a lot of people with this problem as well car has 145,500 miles now I have the oil and oil filter changed every 5,000 miles. I really think that this needs to be investigated asap as this could cost an accident if car brakes down.

About 9 months ago, I started my 2011 Kia Forte up and it cut off. Happened on and off for the next 6 months or so, gradually getting worse and more often. Decided to take it to Kia, needed an oil change done at same time. Kia dealership said there is metal in my oil and means engine is failing. The stalling they said was a computer issue and reset it. Did another oil change about 3 months later at another facility, they did not look for the metal or notice any on their own. Today, vibrations started when sitting idle at a traffic light. No check engine light on.

The engine has had a ticking noise which has only become louder with more miles on the engine. The car has been serviced by Kia dealership regularly. The car started stalling during random times while drive. You release the gas pedal, it will almost stop. You push the gas pedal and sometimes you will regain power to the engine. This has almost caused me to have several accidnts. The car was taken to the Kia dealer and told the engine oil level was low. It was change 3 months earlier and had not been driven more than 1000 miles. The Kia dealer said it was an engine failure and would need to be replaced. I researched the car and discovered that it had 2 recalls. I have never received any information about any recall on this car ever. I was not notified of any recall when it was serviced at Kia for routine maintenance (oil and brake changes). I have owned the vehicle for 10 years now and it has 100,000 miles. I am disappointed in the engine failure which I was told $4600 to have a used replacement installed by Kia. I am seriously upset that I bought this car at the Kia dealership. Had it serviced at a Kia dealership multiple times and no one told me about any recalls, and I never received anything in the mail, email or by phone. Isn't Kia responsible to notify consumers when recalls happen etc?

I HAVE HAD A TICKING NOISE COMING FROM MY ENGINE FOR A WHILE AND JUST IN THE PAST 2 MONTHS THE TICKING HAS GOTTEN MUCH LOUDER. THE CHECK ENGINE LIGHT HAS COME ON AND WENT OFF- I HAD TO REPLACE THE CAMSHAFT SENSOR AND THE CRANKSHAFT SENSOR. THE TICKING SOUND STILL CONTINUES -BROUGHT TO KIA THOUGHT IT COULD POSSIBLY BE INTERNAL ENGINE FAILURE STARTING TO OCCUR BASED ON SOUND OF ENGINE BUT NOTHING DEFINITE. I HAVE FELT SAFE WITH THIS CAR BUT NOW NOT SO SURE. I HAVE FAITHFULLY CHANGED MY OIL EVERY 3 MONTHS SINCE I BOUGHT THIS CAR BRAND NEW IN 2011.

AFTER OWNING MY 2011 KIA FORTE FOR THE LAST 6 YEARS IT HAS DEVELOPED A TICKING SOUND IN THE ENGINE. IT IS VERY MILD WHILE IDLING, AND WHILE RPMS ARE UNDER 1500. AFTER RPMS GO PAST 2000 THE TICKING NOISE IS PROGRESSIVELY LOUDER. WHEN I BOUGHT THE CAR IT HAD ROUGHLY 85,000 MILES ON IT AND NOW HAS $125,000. I HAVE HAD REGULAR OIL CHANGES ON IT, EVERY 3000-5000 MILES. AFTER HEARING THE TICKING I TOOK IT IN TO MY MECHANIC WHO SAID THIS IS A REGULAR OCCURRENCE WITH KIA FORTES AND THAT THE ONLY FIX IS REPLACING OR REPAIRING THE ENGINE. I HAVE BEEN DOING A LOT OF RESEARCH AND READING A LOT OF COMPLAINTS ON THIS WEBSITE ABOUT KIA ENGINES GOING BAD AROUND 100,000 MILES AND I BELIEVE YOU SHOULD LOOK INTO KIA FOR THIS. THERE NEEDS TO BE A RECALL ON KIA'S ENGINES.

HI I BELIEVE U SHOULD HAVE A RECALL ON THE ENGINES FOR AN EXAMPLE WHEN I LOOK UP THE TIMING CHANGE ITS SAYS MOST HAD TO REPLACE THEN THE PISTON SLOP IS KNOCKING AND IT SEEMS LIKE MOST HAD TO REPLACE THAT. I HAVE BEEN LOOKING FOR A REBUILD KIT FOR MY KIA AND WOULD LIKE TO JUST REBUILD IT MYSELF BUT CAN'T SEEM TO FIND A 2.0 REBUILD KIT FOR A 2011 FORTE EX ONLINE... WHY IS THAT?

THERE IS A CONSTANT KNOCKING COMING FROM THE ENGINE AND LOUD NOISE WHEN ACCELERATING THE ENGINE. THE CHECK ENGINE LIGHT IS ALSO TURNING ON AND OFF. 2012-2015 KIA FORTE KOUPS HAVE RECENTLY BEEN RECALLED, BUT NOT THE 2011 MODEL. THIS CAR HAS THE SAME THETA 2 ENGINE AND THE SAME PROBLEMS. THE ENGINE IS SHOT AND WILL NOT LAST MUCH LONGER. I SINCERELY HOPE THE RECALL IS EXTENDED TO THE 2011 MODEL KIA FORTE KOUP. *TR

KNOCKING FROM THE ENGINE STARTED ABOUT 90,000 MILES, MAYBE EARLIER ALL SERVICE DONE TIMELY BY DEALERSHIP. KIA DEALERSHIP UNABLE TO HEAR ANYTHING UNUSUAL - STATES CAR'S GETTING OLD (7 YR). KNOCKING WHEN CAR STATIONARY AND MOVING. KNOCKING IS GETTING MUCH MORE PRONOUNCED. PROBLEM DIAGNOSED AS THE SAME FOR SO MANY KIAS - ROD BEARING. CAR IS SPENDING A LOT OF TIME SITTING IN THE DRIVE - I DON'T BELIEVE IT'S SAFE FOR ANY TRIP - OR FOR ANYONE. RECOMMENDED SOLUTION: NEW ENGINE. WHY WOULD I PUT A NEW ENGINE IN A, NOW 9 YEAR OLD CAR - SO THAT I COULD KEEP A KIA PRODUCT. NOT HAPPENING! WHAT IS HAPPENING IS ME LETTING EVERYONE KNOW TO STAY AWAY FROM ANY KIA PRODUCT!

MY MECHANIC DIAGNOSED THE PROBLEM AS THE ROD BEARING THAT'S THE CAUSE AND SUGGESTED I CONFIRM THE DIAGNOSIS WITH A KIA DEALERSHIP TO SEE IF KIA WOULD COVER THE COST. THE KIA DEALERSHIP DIAGNOSED THE SAME PROBLEM, REACHED OUT TO KIA TO DISCUSS COVERING THE COSTS, AND KIA TOLD THE DEALERSHIP THAT THEY WOULDN'T. I WAS TOLD EITHER REPLACE THE ENGINE WHICH WITH PARTS AND LABOR WOULD BE AROUND $4,500-$5,000 OR I COULD TRADE IT IN AND GET A FEW HUNDRED FOR IT. WHY ON EARTH WOULD I BUY ANOTHER KIA IF THEY'RE NOT EVEN GOING TO RECTIFY THE PROBLEM WHEN IT TURNS OUT TO BE AN ASSEMBLY DEFECT TO BEGIN WITH. WHAT'S EVEN MORE FRUSTRATING IS THAT THERE IS A ENGINE RECALL ON OPTIMAS AND SPORTAGES WITHIN THE SAME YEAR AS MY FORTE BUT THEY DON'T FEEL THE NEED TO OPEN UP A RECALL. READING ABOUT IT ONLINE THERE HAVE BEEN HUNDREDS OF COMPLAINTS ABOUT THE SAME (ENGINE NEEDS TO BE REPLACED) PROBLEM BUT KIA STILL WON'T DO A RECALL FOR FORTE MODELS IN THE SAME YEAR RANGE. IF KIA WON'T DO RIGHT BY IT'S CUSTOMERS, I DON'T SEE THE MOTIVATION IN CONTINUING TO GIVE THEM MY BUSINESS.
