Throughout november 2019, my 2012 hyundai accent hatchback with automatic transmission( VIN [xxx] ) has been experiencing unintended acceleration. I have taken it to a mechanic who cleaned everything between gas pedal and computer, and the problem ameliorated for a week or so. Now the problem is back. In normal driving, lifting my foot off the accelerator sometimes slows the vehicle and other times it maintains speed or accelerates. (this is without cruise control engaged). When stopped in traffic, it will lurch forward when brake is released. When parking it often red-lines as soon as [ut into neutral. So far my remedy has been to turn the key off. However, my wife is now too frightened to ride in the car. I see all the other complaints of unintended acceleration in your database. How many deaths will it take for you to wake up to a serious defect? Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

My car was parked in my driveway. I went out to pull it into the garage. When I took my foot off of the break to excelerate, the car lunged forward (without me giving it any gas). I returned my foot lightly to the break. The thrust threw me into the steering wheel. I called the tow service and had my car taken to the dealership for repair. During the ride to the dealer the tow driver said that he had to hold his foot on the break in order to control the car and get it on the truck. The dealership kept my car for three days and told me that there was nothing wrong with it. She told me that the diagnostic showed no numbers that would indicate there was anything wrong with the car. She stated that there were some codes that came up but they were erased because they didn't matter, they came up on their own. The diagnostic was done on day one. What was being done on the other two days? This is not the first time that I have had to take this car in for this type of repair. They always tell me that there is nothing wrong with the car, however when I get the car back it drives like new. Not so much this time. The breaks are still a little off. Is a dealership allowed to repair your car and not tell you what was wrong? I ask this because of the above and during one of my visits on of the workers told me that "they will do anything to stay #1".

We purchased a 2012 hyundai accent on october 19, 2011. From the very first day we started having issues where the brakes would not brake at times and would have bouts of unintended acceleration. From the first day of purchase we advised the hyundai dealership and even brought in our vehicle to be looked at. They refused to do any kind of diagnostic and said that I was being a paranoid woman and new moms tend to worry too much. My husband and I have both driven this vehicle and experienced this issue. We advised hyundai, the dealership and our insurance company of the issue. Each time we brought the car into the dealership the acted very cavalier as it was "not a big deal" and would send us on our way. We had various communications and have paperwork where the dealership noted we were complaining of the brakes not working and then they would state they did not/will not do a diagnostic. I would not allow my children to ride in this vehicle further as it became apparent that this was not only going to keep happening but as time passed it happened more frequently and caused me to fear for my life. In december 2013 I advised my husband I feared for my life. One week later 12/16/13 I was in an accident where I was slowly turning, went to brake and the brakes felt empty as they did when this would happen and the car revved loudly and accelerated at an extreme speed. These bouts of unintended acceleration are documented yet hyundai and the hyundai dealership will not respond appropriately,. They dismissed my claim stating our floor mat protector which lays flat and has plenty of clearance is the cause however I must advise and have responded that the floor mat protectors were not purchased until the following year and did not get put into the vehicle until july of 2013 so the documented incidents were mostly before and one in july 2013 after they had been placed in the car.

What is wrong
Vehicle description: passenger vehicles equipped with 1.5 liter or 1.6 liter engines that were originally sold in or currently registered in the states of alaska, colorado, idaho, illinois, indiana, iowa, kansas, maine, massachusetts, michigan, minnesota, missouri, montana, north dakota, nebraska, new hampshire, new york, ohio, pennsylvania, south dakota, vermont, wisconsin, and wyoming. While driving at a steady throttle opening for an extended period of time during extremely cold ambient temperatures (below approximately -5 degrees fahrenheit with high humidity), moisture in the combustion chamber blowby gases can freeze and block the positive crankcase ventilation (pcv) valve and hose. If the pcv hose freezes, combustion chamber gases are forced through the breather hose into the air intake hose and then into the throttle body.
Risk
Moisture in the combustion chamber blowby gases may freeze inside the throttle body bore and throttle body idle speed control circuit resulting in the throttle valve not closing fully and a higher than normal idle speed when the accelerator pedal is released.
Remedy
Dealers will install a new, relocated pcv hose and will additionally install a heated throttle body on the 2000-2001 accents equipped with 1.5 liter engines that were produced through january 31, 2001. Owner notification began april 15, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact hyundai at 1‑800‑633‑5151.
