Hyundai XG350 jerking problems

1) The vehicle idle is too high. It jerks forward every time I'm at a stop then I want to go forward. I have almost ran into the back of other cars while waiting at a stop sign. 2) The bolts and Subframe is coming detached from the car. It has been confirmed by dealership and franchise auto repair places (2 of them) that the car motor is knocking around and the subframe is loose! I've currently spent over $2000 alone in repairs on the suspension, rack and pinion & oil leak & manifold intake issues since purchase in 2019. Besides the check engine light turning on and off, there was no prior warning of the subframe and/or it's bolts being rusted out prior to purchase or prior to mechanics telling me about this dangerous repair needing done. Why is the 2001-2004 XG350 have recalls on this but not the 2005 year model that is exactly the same specs and materials used as the 2004????????????????????

I was almost parked at the curb in front of a drugstore with my foot on brake easing into spot when car lurched forward, jumped the curb and violently crashed into the concrete wall about 6-7 feet away. Wall, not brake, stopped car. People came out from store as crash was heard/felt inside. I don't know what would have happened to me if I didn't have seatbelt on. As it was, my chest was extremely sore for several weeks from seatbelt. Airbag didn't deploy. Car was totaled thank god as I would never drive it again. So many complaints with same issue no recalls or service bulletins. Hyundai line is can't find anything wrong when car was checked by them after accident so it is driver error. I've been driving for many years and never had an accident and still consider that I didn't have an accident but not sure of insurance company's stand if I buy another car, if I can find a safe one after all of the recalls. This situation is unacceptable.

I have a 2004 hyundai xg350. Many times when I leave the car overnight (or for a few hours) and then start it back again, the gear does not engage when I put it in drive. When I press the accelerator, after a few seconds, the gear engages suddenly and the car lurches forward. The problem persists for the first few minutes while I am driving. So when I am making a turn, again the car has to start from zero, so it wouldn't move for the first few seconds and just jump forward. This can be very risky at times, especially on turns. Once the engine is heated up, there is no problem. I have also found other people facing same issue but not fix for this problem yet. I wish a class action lawsuit could be filed against hyundai.

Tl*the contact owns a 2005 hyundai xg350. While driving approximately 70 MPH the vehicle started to jerk. The vehicle was taken to the dealer where the technicians stated there was a loose pin in the throttle body sensor. The technicians tightened the pin; however, the vehicle continued to jerk after the repairs. Prior to the failure occurring the dealer replaced the transmission for an unrelated failure. After the replacement of the transmission the jerking motion in the vehicle recurred. The vehicle was taken to an independent mechanic who stated that the transmission converter would slip out of gear and would not stay engaged. The contact stated that the warranty was valid; however, the dealer stated that until a service engine light illuminated they could not repair the failure because the computer was not reading a failure code. The vehicle was not repaired. The approximate failure mileage was 90,000.

2005 xg350 has had two specific problems related to engaging car in drive and acceleration. When car has been sitting overnight or for a prolonged period of time and it is placed in drive, the car just sits there in excess of 15 seconds and then transmission clunks into gear and starts going. This problem occurs daily when car is first started and reappears if car cools down for several hours after it has been driven. Related to this problem is acceleration of vehicle. After gear finally engages, the slightest pressure on the gas pedal can send the car lurching forward quickly. The other day while backing out of the driveway and then placing car in drive, was almost hit by another car coming down the street that no doubt expected us to be moving. Even though we had placed the car in drive, it went nowhere. Lucky the other guys stopped in time or we would have been hit. This could be a real safety issue. We have reported these problems to dealer on two separate occasions but they have been unable to replicate them and nothing has been done to resolve our problem.

Purchased xg350 in december 2005 on two occasions when first leaving the driveway noticed that when pressing the accelerator the car did not respond. After releasing and trying a couple more times the car then lurched forward. That was shortly after the purchase. Now have a little over 26,000 miles on several occasions when pressing the accelerator the car seemed to surge forward for the amount of pressure. On july 16, 2007 left the driveway and the car would not respond to pressure. Kept trying for about 1/2 mile pressing and releasing and just as I was going to turn around the car surged forward and drove fine for the last two days. I will be taking it to a hyundai repair service department soon as this could be very dangerous if pulling into or driving in heave traffic.

Car accelerates/lurches forward when idle or starting to drive from a standstill. This happens intermittently and my wife has taken it to the dealer twice for this. The dealer states they cannot find anything wrong. Well, by reading the complaints on this site about the same problem my wife is experiencing, there is a problem, and a serious one.

The engine has periods where it will accelerate on its own. The engine will run rough while at the same time the rpms will increase dramatically. The vehicle will lurch forward with only control of the brake preventing an accident. The vehicle has been taken to the dealership for the 6th time. This time was only two days after the vehicle was returned as "repaired". The vehicle was towed to the shop. Dealer has replaced several components to include electronics and the throttle body. I was told that the last repair involved actual rewiring of accelerator components based on recommendations from the manufacturer. The problem is a serious safety concern.

My 2005 hyundai xg350 has a very dangerous hesitation problem. This problem is generally encountered form a cold start out of a parking lot or garage. The gas pedal is slowly depressed to accelerate. Sometimes, it responds normally. At other times it just coasts no matter how hard you push on gas pedal. Suddenly it will lurch forward with enormous torque (depending on how the driver responds to the coasting problem). There are two problems with this hesitation: 1) pulling into traffic and than not accelerating can cause accidents 2) more importantly, the unexpected quick acceleration can cause loss of control, hitting something or somebody, or worse. Resolution to this problem is not considered by huyndai at this point. Denial of other cars having similar problems are common at factory level, but are admitted at dealership level. Incident date is first time.
