It won't catch up speed it slips on the freeway. Once I pass 60 miles per hour it excelerates very high and rpm get stuck after I hit 50 miles per hour. There's a knocking noise coming from the engine and burns oil fast.

Throttle control system vulnerabilities
The Office of Defects Investigation (ODI) of the federal safety agency received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. the federal safety agency's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in the federal safety agency's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, the federal safety agency does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing the federal safety agency?s reasons for denial of the petition will be published.

What 2012 Kia Sorento owners say
Most recent owner complaints, unedited.
(January 11,2024) my wife had an accident while driving a 2012 Kia Sorento vehicle. She was waiting to enter a parking space at the Laurel Mall that someone was backing out of, when the space was clear to enter, she took her foot off the brake and proceeded to enter the space. It seems that the Sorento went full throttle on it's own and proceeded to smash into 3 other parked cars. I read that Kia has a problem with faulty acceleration on 2009 thru 2015 with the Sorentos. I reported this incindent to my insurance and they recommended that I contact Kia Motors Direct. I have reported this to Kia Motors Customer Care, (January 12, 2024) I am waiting for their reply to this situation. There were no warning lights nor any warning of a failure with the vehicle. To date, the Sorento has not been repaired nor checked by a mechanic.
The abs brake light, traction control, and downhill assist lights all came on at the same time. This is being caused by a faulty speed sensor. This item was recalled on the two wheel drive kias, but not the all wheel drive models... hiwever.. looking for answers in the forums show that there is a systemic problem in the kia system, just Google search it and watch all the other car owners stories pop up.
The vehicle slows unexpectedly while driving and will not go above 2 RPM causing me to slow to below 40 mph on the highway without any warning. I took the vehicle to Kia for an airbag recall and suddenly I started to have these engine problems. They never informed me there was a recall on my vehicle or that this issue could occur. I am not the original owner and acquired the vehicle from my dad, which he purchased from someone else. I had the vehicle checked out by AAA and the knock sensor was replaced, yet the issue continued to happen. I took the vehicle back to Kia because AAA could not figure out why the car continues to have this engine issue. Kia cannot seem to figure out the issue as well but stated the engine needs to be replaced. We asked them about the recall because I suddenly received notice about the class action lawsuit, but the vehicle has 185,472 miles on it and they refused to correct the issue and said the new engine will cost $7200. The issue has almost placed me in several accidents because the vehicle abruptly slows down and I have to pull to the side of the road use a code reader to clear the code in order to drive again but it continues to happen multiple times while driving and I need to get to work. The problem has been confirmed by Kia, but they won't replace it. We were encouraged to file a complaint and see if Kia will take responsibility for their engine since it has been recalled for this issue and a lawsuit ensued. The engine light appears when the car fails to drive properly.
I was driving my car on the highway and entered a ramp to another highway and as I began to accelerate again it was like my engine shut down and there was no response to the gas pedal for throttle. I pulled my car over to the side, sat for a moment, and then turned the car back on. I was able to accelerate, but if I accelerate too fast the engine would shut back down. I contacted Kia and they said all recalls have been processed for my vehicle, but now out of nowhere it's hardly driveable. I am still forced to use this car for short distances under a couple miles for work, but the vehicle's engine will try to shut off over 2k rpms. I have maintenance records for every year with this vehicle and I don't get how this just happens. My mechanic says a Knock Sensor is telling the engine to turn off and my local kia store said there wouldn't be anything to do without a recall.
I have owned my 2012 KIA Sorento since 2014 and thoroughly enjoy my car. After 9 years of satisfactory ownership which include dealer servicing, my car scared me and now I question my safety. On Friday 24th, 2023, I pulled into my driveway and the car suddenly accelerated out of control. The brakes did nothing to slow its acceleration. By the time I reached the key and turned the car off it had accelerated thru 130 feet of a very muddy back yard. (The all-wheel drive is very effective) Fortunately, I just missed a huge 100-year-old pecan tree and stopped just short of the tree line in the back. This ripped the tire off one of my rims and I had a mechanic change the spare so we could retrieve the car. I am taking the car to the KIA dealer on Monday morning 27th. to find out what happened!!
was driving and no warning lights came on and then the engine seized up after buying it 3 months ago. then took towed to kia vw billings mt and they now have had the car for almost two weeks and none of my rights are being met and no communication back to me wont respond to several of my calls. i will be filing a lawsuit against either auto resource in billings mt for selling me a faulty vehicle or going after kia vw of billings mt for lost wages as i drive for a living and im disabled and have been treated very very poorly.
Engine suddenly lost power while on 125 mile road trip. Tachometer flat lined at 60 mph and speed and engine power rapidly decreased ( as if in creeper mode) and I was not able to accelerate above the 20 mph , enough to get to the shoulder. I was towed to the Kia dealership and after a day the couldn't replicate the problem as the vehicle returned to it's proper operational mode. This happened again 3 weeks later at 80mph in the center lane under cruise control with the same issues, sudden loss of power, inability to accelerate and no tachometer reading yet still running at idle. This time I pulled into a gas station and took the battery cable off for 5 minutes then replaced it. The vehicle became fully operational and I drove another 125 miles home. I bare was able to get over as I couldn't accelerate the vehicle and had to creep up the exit ramp. This being extra hazardous as it was nightfall and both times I had my 2 year old grandson with me. If I was in the left lane I would not have been able to make it across the highway and possibly would have caused a major back up putting myself, grandson and the other drivers on the road at risk of a collision...There are many blogs in line with Kia owners reporting this same problem and with no resolution if the dealerships can't replicate the problem while they have the vehicle.
On 03/22/21, at 8.00am was a regular visit for oil change, finally around 1pm my car was showing on the dashboard the "engine light", never happen before, I claimed verbally why, that happen now. I am driving because they told me is safe and I believe, and waiting the appointment for( recall 20v750) thanks to all.
I was driving on a busy street and my kia started making a rattling noise when I pressed on the gasand then my check engine light came on check battery life and the oil light and then it diedwhile I was driving
