This car accelerates while unattended. Most likely due to an ECM malfunction and unable to properly respond/send signals to the motor. On 4 occasions, the car has accelerated, even if in park. It will go 25mph on its own and to stop I had to put it in neutral. I-??ve seen that my car isn-??t the only one experiencing this. Considering it-??s an ECM issue there should be a recall because that is not a part you change during the life of a car.
The contact owns a 2005 Hyundai Tucson. The contact stated that on several occasions while driving 65 MPH and attempting to accelerate, the RPM failed to raise, and the vehicle failed to respond. No warning lights were illuminated. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 105,000.
Initial issues on vehicle presented in January 2021 with various check engine light codes including P0133. Although vehicle passed emissions in 2020, various check engine codes for mass air flow sensor, oxygen sensors, misfire for various cylinders. After replacing indicated mass air flow sensor, oxygen sensors indicated via obd II tool, battery, alternator (more than once), both front cv boots, head gasket seals for both cylinder banks, more check engine light issues appear according to the vehicle. Currently another cylinder misfire check engine code has appeared after all spark plugs have been replaced with oem recommended brand replacements (nkg pre-gapped spark plugs). The misfire code has cleared at this time. The current check engine code from the obd II tool is error code for drive train driveability P0420 regarding catalyst system operating below threshold at bank 1. I have utilized local store catalytic cleaner liquids to clean the system, which has not resolved this issue. Additionally, beginning in January 2021, the vehicle was taken to the closest local dealship for a large majority of these repairs including a $150 dealership fee just to have these codes reviewed and additional fees for the labor to address for each issue for each repair.

The sensors were replaced however, ten days later the failure recurred. Laurel Hyundai located at 998 eisenhower blvd, johnstown, pa 15904 was notified of the failure.

The first time this happened I was pulling into a parking place in a shopping center. As I was turning into the parking place I very lightly tapped the accelerator and the engine reved up and I applied the brake only to have the car continue forward and go up the cement curb. I then pushed down on the brake pedal as hard as I could and only then did the car stop. If the cement block had not been there, I would have hit the car parked directly in front of me. The front tires had gone about two feet up on the cement block. The next time this happened I was once again parking. This time I was parking parallel to the curb. I pulled into and in front of the space I was going to park in. I put the car in reverse and began to back up slowly with my foot over the brake pedal. Suddenly, the engine reved up and the car lurched backward. This time I applied the brake very hard and I was able to stop my car before I hit car in back of me.

I was slowing to a stop and could feel that the car was going to die and it did. I took it to the dealer and they did a fuel induction service and it seemed to fix the problem.the dealer should have not charged me for a car so new, but they put under the service "maintenance" which I didn't find out till a couple years later when it happened again and I called the dealership. I have since had the same incident happen 5 times and after reading several people have had the same thing with no explanation I decided to put my incidents in so that more people would know it isn't just a single happening of the same thing. After this happens I take the car on the freeway and floor it meaning to blow out what I think may be stuck in the fuel line"??" it always works for a while. This thing doesn't occur for any particular reason and I have the car well maintained. I now have over 120,000 miles and the last time it did this was about 6 months ago. Thank goodness nothing bad has happened because of it.
Engine on our 2005 Hyundai Tucson turned off in the middle of a busy highway going approximately 40 mph. Managed to turn/roll off the road without power or power steering. Had to restart car several times as it would stall out on acceleration or when slowing to turn. Paid dealership $209 to "fix" the problem, but the problem still exists a month later and is getting progressively worse each day. Dealership did oil change, vehicle inspection and replaced "P0444 evap purge control valve connector." Clearly this did not solve the problem as this severe safety hazard persists. Hyundai has no answers and several other similar complaints we've read have been filed with the NHTSA. Something has got to be done.
Transmission keeps slipping out of gear when you put into gear and car won't move. You stop at a light and even though car is in gear it won't move. Flip it back and forth on auto gear shift sometimes it moves. Other times it changes gears or slips out.
While stopped at a light the engine revved up to a high rate. I tried to put the transmission into neutral but put it into reverse instead, the high rate of revs continued, finally got it into neutral and engine went back to normal idle speed. When light changed put transmission into drive and proceeded home (a few blocks) without incident. This happened about 13 months ago whereby the mechanic replaced the idle speed control and throttle position sensor. Also they did a throttle body and fuel injection service at that time.

No error codes came up this has happened three more times with the same results at different auto shops. I have contacted Hyundai they say they are not aware of any problems. Doing some internet research shows that many people are having the same issue this is a safety issue it could easily cause an accident.

Vehicle was traveling at approximately 40 mph when the vehicle suddenly stopped running and blocked the center lane of traffic on a busy thoroughfare during rush hour. Attempts to restart the vehicle were unsuccessful at first. After 15 minutes vehicle was able to start and stayed running. This type of incident has also happened in the past - vehicle will be traveling at speed and will just suddenly shut off and not restart. Vehicle has been taken to a service shop to be evaluated. Vehicle has a new coil pack, plugs, wires, throttle position sensor, A/C compressor, and timing belt. Vehicle, once repaired, is going be sold due to its continued unreliability and tendency to just stall at any time at any speed.
Misfire cylinder #5. this has been an ongoing problem shortly after my mother gave me the vehicle at apx. 24,000 miles. The car was transported from the East coast here to Arizona. It has been in and out of Hyundai dealerships and still no fix, with my father paying the bills, which is hard for him being on a fixed income, but my safety as well as his grand children are paramount. The vehicle will quickly slow down from a 70 mph speed to 35mph without warning and sometimes the engine light will come on (code P0305). I made a complaint once before (case #389816). This continuing problem with no fix has me have several near misses of a rear end collision, which so far I have been lucky not to have. The most recent repair was on June 14th thru 15th, 2013 and the problem was back on the Monday after picking the vehicle on Sunday, the 16th. When the problem first happened the vehicle was still under the extended service agreement and of course it's now expired will the same problem that wasn't researched during that time. I have seen many comments with owners having the same issues on Hyundai's forums, so it's not my imagination. Can someone please investigate these claims so that the problem can be solved? if I could afford a new vehicle it would solve my problem and pass it to someone else, but I don't have the money to do that. Please help, thank you.
