The engine started consuming large amount of oil 10 months ago when it was about 170,000 miles in it. That is, the oil goes below the low mark when the car is driven about 800 miles after the oil change, and keeps going down to the empty level when the car is driven about 1,200 miles. I also hear of rattling-like sound when accelerating. I have to check and add oil every 500 miles. I was recently told that this issue may lead to the fire on the engine and noticed that Kia recalled regarding this similar issue for many other cars. I didn't see any signs of leaking when I checked several times the floor in a spot where I parked. I'm not sure if this was related, but the engine died, about 4- months before I noticed that the engine started consuming oil, when I drove up hill. The car was towed in to a Kia dealership in that area, and what a technician said is that there was a problem with fuel line or pump. They charged $700 for this job.

- Folsom, CA, USA

I am driving through an intersection and just as I get through, while still in motion, all the lights on the dashboard flashed or turned on. I lost complete control of the gas pedal, lost power steering, and I was forced to pull off into a parking lot where I couldn't get to a parking spot and was left stuck at the entrance of the establishment. I put my car in neutral and pushed it away from the entrance after trying to turn it off and start it back up several times. I was forced to call a tow truck to get towed to my repair shop and the diagnosis was that the engine blew a bearing and will need an engine replacement.

- Byfield, MA, USA

While driving on interstate at 3:30 am, oil light flickered occasionally, vehicle started slowing down, and engine eventually stalled, and would not restart. Had aaa tow it to a trusted repair shop near my home, and they determined that the engine had siezed. Had vehicle towed back home, pending decision on what to do next. The vehicle had been previously inspected by a Kia dealer under the SC147 engine recall on 9/22/2017 (16+ months earlier) at odometer 89,547 miles and evidently passed the inspection procedure per Kia's tsb. I believe debris from the engine manufacturing process blocked oil lubrication passageways not only to the engine bearings, but also to the oil pressure sensor. I do not believe the inspection procedure developed by Kia to determine whether the engine is ok or needs to be replaced is 100% effective.

The contact owns a 2011 Kia Optima. The contact received an unknown recall notification regarding the engine. The vehicle was taken to sunset Kia of bradenton (4770 14th St w, bradenton, fl 34207, (941) 752-1000) where the engine was tested and passed. The contact stated that the engine had been sputtering prior to the test. The dealer stated that the failure was due to lack of oil, although the vehicle recently had an oil change. The dealer also stated that they did not find metal shavings while conducting the test and the check oil indicator was not illuminated. Approximately one week later, while driving, the engine seized in the middle of the road. The vehicle was towed back to the same dealer who stated that a new engine was needed due to the recall. The check engine indicator illuminated and the vehicle was towed to another unknown dealer where additional recalls were discovered. The unknown dealer found a deteriorated clamp that caused the hose to become loose and the engine to jolt. The vehicle was repaired, but there was no mention of the deteriorated clamps on the invoice. When the contact retrieved the vehicle, the air bag indicator illuminated. The dealer stated that the indicator was illuminated when they received the vehicle. The contact also noticed a fuel odor and noticed that the fuel pump was gushing fuel.

Vehicle will not start. Engine and ignition replaced due to bearing wear recall. Transmission replaced 2 weeks ago for rebuilt one, and now car won't start. It's been 2 days and Kia has not been able to tell me what is wrong with it. The reason I wanted to submit this complaint is because I believe there should be a recall on transmissions installed in these vehicles. Kia wanted me to wait from 10 Sep to mid Dec because these transmissions are on back order. Which means there's so much demand that Dec is the earliest they could receive it. Their shop is full, mostly of these cars (Optima). They expected me to wait 3 months without a car in order to give them time. It just boggles my mind that they could do this. The craziest thing is that expect everyone to wait this long. I talked to 3 different costumers who are all having the same exact problem with the same cars, and they were told the same thing. I purchased this vehicle in 2014 used, only one previous owner, never had any accidents, now has 111,000+ miles. Always did all maintenance checks, oil & filter changes, tune ups, fluids change and yearly inspections. Only used for going to work and coming home 5 days a week (approx. 54 miles per day). I decided to repair transmission at other place & ended up saving $1100. Kia wanted to charge $2,700 for rebuild transmission & found a guy that charged me $1,600 for rebuild one. Kia never gave me quote copy. Just told me over the phone. How convenient! guy told me the way these transmissions were built it's simply bad engineering. And showed me the part of the transmission that broke. Would upload the documents, but I left in my car! can still provide them though! the safety issue was that the transmission went out while driving at 65 mph on a busy highway in houston! the car simply died on the middle of the highway. So I can only assume you know what that feels like!

The dealer said their was no visible leak and performed a consumption test which showed my car was consuming oil at an alarming rate. This issue has been identified as a know problem with Kia motors and has yet to addressed.
