Addendum # 2 from original complaint and response through senator marco rubio office. 1st addendum dated August 9 2019. Husband arrived at courtesy Kia and as expected, no loaner vehicle. Finally I reached the sales manager and explained how disgusting it would be for a disabled man who is paying for a defective car and promised a loaner to have to call uber. He agreed to loan one under "test drive" guise. Friday 9,2019 heard nothing about our car. We called at 4:30. Fernando stated that they had it in back and did not know what was wrong with it. Saturday 10,2019..1:45, jenny the service advisor called and stated that our car was ready " we put a ksds wiring harness". no further explanation. Not even via email. The service ticket on states...engine noise pass, put wiring harness jumper. I looked at the protocol on NHTSA site. It states clearly. The car must be hooked up to internet everyday and a 21 step procedure to check for engine noise. On the service ticket, mileage was identical in and out. How do you really test a car without driving it. This was a rush job on their part... employees pretending to not know about this massive defect. The 26 page document attached speaks volumes. We asked for a photo of the wiring harness that was damaged. They refused, they also stated that it is being sent back to the manufacturer. Meanwhile...two disabled persons get to drive in fear, live in fear and pay for a defective engine/car and was scammed by citrus Kia, Kia motors, Kia America. Attorneys general, states attorneys, senators, please hold Kia accountable. Please make them actually show up in front of congress ♿ plant city....per the document. Everyday doesn't mean, day and half.

Addendum to the complaint dated January through senator marco rubio office. I received a letter from NHTSA dot that the investigation is open as to the "software upgrade", should be labeled recall and into the "theta engine", see attached. As I write this, my disabled husband is in a tow truck with the driver because he went to the dollar general store, turned the corner onto a busy highway and the car limp mode light came on, car shut down dangerously slow. Luckily he was not rear-ended. This is pathetic for Kia motors, Kia America to get away with this. These vehicles need to be bought back. They have no clue what is really happening. We took our car in a couple of months ago to courtesy Kia for an oil change. They said all was good. Clearly it is not ! Kia did us, two disabled americans wrong. Soul 1st, scammed into going more in depth because soul was bad... knowing there is a major defect. That is deceptive trade practice. Plain and simple and dealer's are complicit. Please get these cars off of the rode. It has been noted on forums that Kia is putting used motors. Please do something. We are not safe, our grandchildren are not safe. States attorneys, attorney general's, senators, etc. Help all of us. We lost our home to toxic drywall, now this. Plant city. ♿

Driving my Kia Sportage (GT line) at about 30-40 miles/hour, descending red hills (jamaica) and without warning the car went dead, all the light comes on on the dash and the speed cut drastically. It was scary and I can only imagine if it was on the highway. Afraid to drive it.

In motion ; vehicle does not accelerate properly, no pickup my life in danger several times. Kia has sent letter in which I followed instructions. Dealership updated system. Now my diagnostic system is not working putting me at even greater risk no warning light indicate engine trouble. According to Kia, the recall I received in the mail was specifically done so I would have warning light take asap to dealership.., cleaning out all my bank accounts- Kia finance never sent right title in my legal name after I faxed front and back end, with docs they requested. Called weekly & because of there mistake he has stolen 1000S of dollars from my accounts. He is not a citizen so he doesn┐T care about our laws. He con cpa to forge taxes now ihavetohelp irs straighten it out. The cpa ┐died I was told┐ I having medical issues from stress anxiety. I never wanted new Kia...but he sold it behind my back. Then bought most expensive car leaving me with -17;000 equity. On a car he ragged to hell and wrecked. Then canceled all extras including disabilty leaving me with no other choice but to trust owner. At the time ; my credit was 780; never missed a payment but had no work history due to tax fraud. The car has never ran correct I knew from day 1 it was pulling I realized Kia had put a 4 cylinder in a SUV that should be a 6. now the recalls ironically timed when you came out with same car but a 6 cylinder changed the name. I paid 8;000 total traded 2 cars. Kia finance stated I never missed a payment until now. Due to continued abuse from my ex spouse. Transunion has frozen my credit reports, labeled me a true victim of stolen identity.and financial fraud. Kia to buy my car back so I can buy the car I want. Transunion, police, lifelock, wells fargo, criminal investigation, emergency hearing for protective order and state farm's have protected me.

Vehicle suddenly decelerated to 20 mph on one way highway in a passing zone. Problem then diagnosed as engine failure. 5 weeks later, with vehicle still out of service, diagnosed instead as wiring harness problem. Wiring harness replaced. Brand new car, 11 months old, 5,925 miles, serviced with first oil change 5 days before problem occurred. Kia roadside assistance had no regard for my safety on the side of a dangerous freeway and had to be resolved two hours later with aaa service towing. Still no reimbursement from Kia.

2018 Kia Sportage. Consumer writes in regards to engine failure. Consumer sent additional correspondence. The consumer stated the dealer denied assistance with the failure due to an after market oil plug being installed in the vehicle. The dealer advised that the 3rd party who changed the oil should be held responsible for the failure. The engine failed and needed to be replaced. Metal shavings were found in the oil.

I had a total engine failure on I-75 with my 2018 Kia Sportage with just over 18,000 miles. My insurance carrier (usaa) person I spoke with said I was the third person she has spoken with in the last week that had the same make & model number that the engine failed. She said one person was told by her dealer it could be six months before they can get her an engine. I am in naples Florida and deal with airport Kia in naples, fl.

For the past 6 months or so, I've been experiencing an unknown issue. I'll be driving along, steadily and all of a sudden my engine and RPM gauge will rev up and then go back to normal. My speed doesn't change, no lights go on, just the rev-ing sound and the gauge goes up. It's very alarming to me. I've checked with Kia and they're aware of the issue but state that there is currently no recall or alert as to what exactly the problem is or how to solve it.

I purchased my 2018 Kia Sportage ex brand new 6-8-18. Less than 100 miles on the car and the dashboard instrument lights went dark while driving on the highway in the dark. I brought it back to dealer, they had to order a new gauge dimmer cluster because the original failed. Several weeks later the brakes began violently shaking the car when braking on the highway. Again, I brought it back to the dealer and they resurfaced the brake rotors due to warping. Several months later on 1-28-19 the engine died on the highway placing the vehicle into limp home mode. I almost got hit by a tractor trailer trying to get to the breakdown lane without ample engine power. I immediately drove it to the dealer and it has been there ever since. I got the BBB involved now and I am trying to get the lemon law in place. I am currently in a rental.

After 2 attempts to try and have the soul repaired properly as to steering and at least 30 emails and begging for help, and finding myself the reason there was a recall on a recall...we contacted senator marco rubio who in turn contacted NHTSA, a congressional aide etc. No help came for two disabled persons. I even wrote about the souls catching fire and [xxx] witnessed a soul crash due to steering. We begged citrus Kia, Kia motors, Kia America to refund our money. We lost our home built for our disabilities to toxic drywall, we were in propublica, huff post and tampa bay times. No recovery, we slept in our Kia optima which is why we purchased the soul. Two weeks later, the first recall. 2 yrs no one did a thing. In December at christmas, Kia America " challenge " the dealerships. To sell everything. We were once again duped. Citrus Kia called numerous times, what they did was brought us in under false pretense, they financed thru Kia, the 2018 Sportage. Now, we are in further debt with a car they all knew was defective. "software upgrade", oh and by the way", keep this letter in your glove box for ever "in case" the engine failes and if you, the customer who bought in good faith that it was safer than the soul, if you do not get it to dealer if and when light comes on. You will be considered "abusing the car" the consumer is supposed to drive and live in fear? NHTSA had not approved this bandaid. The 1000 Sportages need to be traded for 2019. This is a sad day when a gai, we have to live and drive in fear and pay money. I have read the news articles, the whistleblower. This "software upgrade" is not right. The fires are horrific. One person stated her car still had issues. This is criminal as to what Kia motors, Kia America, citrus Kia has and is still doing to two disabled persons. We need some help. Our auto insurance premium. Increased.[xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Engine was updated regarding software, but engine shut down while in hwy operation at accelerating speeds and immediatly shut down reducing speed to 20 mph may cause fatal accident if trator trailer rear ends you during this occurace since one was coming up or traffic in general considering people don't react anymore. Dealers seam reluctant to reports these occurances.

I picked up a brand new Kia Sportage sx turbo AWD with 34 miles on it today. It was driving kind of hesitantly, seeming like it was misfiring. About 30 miles later, the check engine light turned on. I immediately called Kia customer service as I have an established relationship with them. They advised to take it to the nearest dealership. I took my car to summit place Kia in auburn hills where the initial diagnosis based on a check engine light reading was an improper fuel/air mixture in cylinder 2. I am not sure what protocol will be followed from this point or what actions will be needed to rectify this issue. However, it is apparent that there is an issue with Kia's gdi turbo engines.
