2017 Hyundai Sonata Vehicle speed control Problems

“Steering- will lose control of steering as the steering wheel will lock up and become to hard to turn. This happeb while in the middle of a turn. Also while driving at 65mph. I had to kill my car and turn it back on. Speed control-will take off or slow down as it wants. Car changes between eco mode or sport mode and I have no knowledge of when it will do it or when it has. Car will jump when in park and foot on brakes.”

“Issue: cruise control speeds up too much going uphill, and slows down too much going downhill. Description: I set my cruise control to 75mph, the car will go over 77mph when going uphill, and slows down below 73mph when going downhill without any driver input. This doesn't occur on other gasoline only Hyundai I drove such as santa fe. It only happens on my Sonata hybrid. I guess Hyundai may need to look into how the electric motor works with cruise control.”

“While going down the highway, the vehicle's check engine, ABS, TPMS, traction control, air bag, electronic steering & emergency brake lights all came on simultaneously. & at that same time the speedometer & tachometer both dropped to 0, the digital display of the engine temp guage, gear setting & other onboard displays went down while the car was in motion on the highway. I was able to safely pull over to the shoulder but once the car was placed in park the shifter locked & I was no longer able to change gear settings.”

“I was driving very slowly to make a turn into my garage when the car accelerated on its own and hit the side of my house breaking through a patio guard rail. The front wheels of the car went over the bulkhead. Insurance company sent a wrecker to retrieve the vehicle. The insurance company totaled the car. This unintended acceleration had occurred once when I was driving on a state road in cruise control when the car accelerated beyond the set cruise control speed. This occurred again on the day before the accident. …”

“Had open recall ,, an ECM update and wile Hyundai in columbia ct. And after it was done the car worked fine for about a week , now I'm lacking acceleration for miles per gallon has decreased 50% burning gas quickly plus is burning about a quart of oil a week, but there's no check engine light, change the spark plugs and air filter still the power has decreased 30%. I noticed that decrease in power when entering on to a highway and I tried to accelerate into traffic but it did not have any power at first until it started bucking and then it's finally getting some momentum. …”
