2010 Hyundai Tucson: jerking or lurching

Filed Apr 8, 2016 · Transmission · 90,000 miles · NH

When traveling at about 35-40 MPH, the vehicle sometimes does not engage when trying to automatically shift to the next gear. This causes the driver to lose all acceleration and essentially puts the vehicle into a coast. Tapping on the accelerator does nothing to engage the transmission again. However, after a few seconds or more, the transmission will finally engage. If you happen to have the accelerator pressed this will lurch the vehicle forward. If you happen to be behind another vehicle this could potential cause an accident by ramming the vehicle in front of you. There have been a couple of 'close calls'. I have videos of the engine revving that I can supply, but the file sizes are too large to upload. This has been occurring since I purchased the vehicle new. They replaced the transmission at 5000 miles for a similar situation. The problem occurrence diminished, but over the years the problem has been happening more frequently. I have always reported this to the dealer when taking it in for service. The dealer has been unable to replicate the situation or offer any solution. They have been supplied with the videos. The exact cause of this is currently unknown.

For awhile noticed occasional but unusual increase in RPM's. Didn't think much of it until incident on highway when car made a loud noise, and lurched forward as if we hit something. Immediately pulled off road, and didn't notice any damage. Took car to dealer when they "reset" something and said the car was good. Problems with RPM's have continued, and took car to dealership 4 more times with identical faults. At one point they replaced a solenoid, which appeared to fix it for about 2 weeks. Were told they can not duplicate the faults, car is fine, and there is nothing they can do. They said the transmission learns your patterns and something might have gotten confused. I'm extremely frustrated with this. It's clearly a safety hazard, that will only continue to get worse. It's my wife's primary vehicle and I fear for her safety. Have read online, and we are not the only 2010 hyundai tucson owners that are experiencing these problems.

Purchased my 2010 hyundai tucson in may 2010. I have had three instances of transmission lockup at 50 MPH. As described by others it feels like you hit something in the road. The car lurches and there is a loud noise. I am very afraid to drive this car, it feels like I will lose control of it one of these times when it happens. The dealership is currently replacing the transmission as per direction from hyundai technical assistance. Not sure if this will fix the problem or just delay it. The vehicle has 8300 miles, it started failing around 6000 miles. Personally, I don't want this vehicle back and feel that an investigation should take place, this is definitely a safety hazard. These vehicles are having transmission failures before the first oil change!

I have had my hyundai tucson for about 5 months, about two months after owning the car the car made a loud clunk and lurched forward,like I got hit from behind or like I hit an animal. I pulled over to see if I did but nothing was there. This happened about three times before I took it to the dealer. They checked it and said everything checked out fine. They reset the transmission, they told me the transmission learns your patterns and something might have gotten confused. Its been about 2 months now since they "fixed" the problem but this morning it happened again and it slammed so hard it made my son and I lurch forward and the seatbelts locked. It is very scary when it happens. I have an appt. This week to get it serviced again, we will see what they say this time. I am very concerned about the safety of the car when this happens.

Sudden downshifting with loud clunk and lurching of vehicle at 35 MPH. Felt as if I had been hit from behind by another vehicle. Instinctively hit the brakes and pulled over to check for exterior damage, and found none. Continued down the road and experienced unusual increases in rpms. When I arrived at my destination, the vehicle would not go in reverse. Owned vehicle only 11 days. Incident occurred at 500 miles. Vehicle towed to dealership. Service center informs me that vehicle seems to be "performing normally," but they are "checking the codes."
