1 Other Fuel System Pump problem

Failure Date: 07/28/2020

My 2012 Optima was taken to imperio kia in dana point for a mandated engine inspection. After the inspection, I noticed the adviser acting strangely. My car engine started to hesitate, and began to smell rubber burning. The dealership did not ever answer the phone, and with 4 weeks they closed down. My car was inspected at kia of irvine, who determined the engine was damaged beyond repair, it had metal pieces and rubber pieces in it, the hoses were disconnected and there was rubber melted onto the exhaust manifold. There were missing clamps and numerous other probems. Kia replaced my engine and turbo with rebuilt parts, after a wait that lasted 4 more weeks. Kia provided me a 5 year extended warranty on all the components that were replaced and damaged in this case #12538291. In 2019, another mandated inspection occurred for the fuel pump system and fuel pipe in the vehicles that previously required a replacement engine, because there was a danger of fire. On July 28, 2020, the Optima started to lose its power, and choked and hesitated upon startup while I was in traffic. It was very dangerous. I reopened the engine claim and took the Optima into the irvine dealership. They clain there is no extended warranty, that it does not exist! they accept no responsibility for the inspection or lack there-of for the fuel pipe, and claim that the warranty and recall do not cover the fuel pump. Agents are working from home due to covid-19, and there is no customer service to speak of. The quote from the dealership is extremely high and they want to charge me a high diagnostic fee as well. I have been through enough trauma because of kia, and I want them to be held accountable. Their warranty records are a disgrace.

2 Other Fuel System Pump problem

Failure Date: 03/07/2020

There's a recall on low pressure fuel hose defect for 2013 and 2014 kia Optima (kia recall #sc187) but my 2012 also has similar fuel smell. I took my car in to kia of irvine (CA) for diagnosis on March 7, 2020 and was told high pressure fuel line connector to fuel pump is missing a small tab and may need replacement. I was also told that since I recently replaced the valve cover gasket myself which would involve disconnecting and reconnecting the fuel line to the fuel pump, they're not responsible for the line missing tab. But the issue is there was no fuel smell after I replaced the gasket. The smell was right after they replaced the turbo which also involved disconnecting and reconnecting the fuel line to fuel pump. Interestingly, there's another similar recall (kia recall #sc172) where it invlove kia's service technician damaging the same fuel line after engine replacement work on numerous vehicles. The fact that kia has had recalls due to fuel odor on same make/ model, and the fuel smell was after they serviced my vehicle, they should be responsible for vehicles fuel line issue. Furthermore kia should take this issue seriously as the car could potentially spark fire. Please help!.

Failure Date: 04/11/2017

My car started smelling like burning plastic and then it completed shut off. Thankfully I was already in a turning lane when this happened. I only had 60k miles on the car at that time. Seemed like after my engine was replaced my windows stopped rolling up. Then my fuel pump went out. I noticed that it felt like someone was pressing on my brake as I was trying to go and then my traction control light would come on. We fixed this. Now it not even a year later and its doing it all over again. This is not safe as people are behind me when this happens.

8 Other Fuel System Pump problem

Failure Date: 03/10/2016

"takata recall" I have a rather new kia Optima. At 70,000 miles my high pressure fuel pump completely went out. This affected my ability to start the car and accelerate as it ws very hesitant and shaky. The car was stationary when I realized the problem. I was attempting to start the car and realized that it took a very long time to start. After realizing this, I immediately took my car to a mechanic to have it inspected and told that the high pressure fuel pump went out. I asked how it happened and he informed me that it had nothing to do with my driving and that it is very likely the product of a faulty fuel pump because that usually doesn't happen with a car with only 70,000 miles on it.

10 Other Fuel System Pump problem

Failure Date: 01/14/2016

Im having intermittent electrical and suspension problems along with sudden increases of power increase and decreases. I was driving to my local mall before my evening class and noticed my car radio and instrument cluster where not operating no lights but car was running fine. I hit the brakes while coming to a stop light in a busy intersection hit a small bump the car decided to accelerate and it felt as if the suspension was loose on the left front side I heard it rattle now this bump wasn't big by any means as I hit the break I could feel the brakes fight with the engine the brake pedal also shook at my feet. I quickly put the kia in neutral and shut the car off still at the light. Put it in park and restarted my car all light and instrument cluster came on along with radio. My Optima felt ok . But later I went to class got into my car and she wouldn't turn over I had to press on the gas to get it to start. I took it to the dealer they said they couldn't find anything besides my high temp fuel pump was giving low pressure codes. I only have 80k on this vehicle but kia said they will not cover it. This a serious safety issue why if my kids where in the car and I did get into a serious accident with them . This needs to be addressed. Something needs to be done before there is a death no after the fact.
