I’m the original owner of a 2012 Hyundai Tucson and have owned the car for 2.5 years; mileage is under 15,000. About 14 months ago, the car started lunging (for lack of a better term) and I’m wondering what could cause this. It happens only in stop & go city traffic, from a stopped position. Lightly depressing the gas pedal will see the tachometer zoom to 3,000 rpm but the vehicle doesn’t respond. Additional light pressure on the gas pedal will then produce a jerk accompanied by a loud THUNK. The first time this happened, I thought the truck behind had rear-ended my car.
I’ve had the vehicle to two different dealers and they both have said the same thing. “We can’t reproduce it; bring it back if it happens again.”
I’m getting very nervous about driving this vehicle and really would just like to get rid of it, but it would weigh heavily on me unloading a lemon on an unsuspecting buyer or dealership.
