The vehicle was taken to an independent mechanic where it was diagnosed that the manuel lever position switch needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 66,700.

When driving (at several different speeds), the motor (RPM's) shoots up, but the car does not accelerate; it also happens when the car is yielding, and as we accelerate into traffic, the car does not accelerate as it should; again, the RPM's shoot up, but the car is not accelerating. It is similar to driving a standard vehicle and accelerating and pushing in the clutch at the same time. The transmission (RPM) problem is extremely concerning to us. We had a 2010 Tucson, which we had exactly the same acceleration problems with. After many service visits to your dealership, the transmission was replaced. The original service visits went on for a period of several months; after the transmission was finally replaced, we were still experiencing the same problems. We expected that this was a one-time problem, and perhaps we just got a lemon. Now that we are experiencing the exact same acceleration problem with the 2012 Tucson, we do not feel safe driving this car. We know from the past experience that this transmission problem will not go away, it will get worse month by month over time, and the car will have to keep being returned to the dealership for diagnosis/repairs. The dealership test drove the car and did not find the problem, because it is an intermittent problem. We are forced to keep driving this vehicle, knowing that it is not safe, and that at some point an accident may occur.

Exiting freeway, decreasing speed, when it felt as though a tire had gone flat. Shimmy and sudden lose of power followed. Steering became difficult. Car had no power, increasing gas only revved engine, but would not move vehicle at all. Was able to roll to the end of the freeway off-ramp and pull near shoulder. Engine continued to run, but sounded like a cement mixer full of large rocks. Once transmission was placed in neutral, it would not shift into any other gear. Also refused to shift into park. Vehicle was flat-bedded to dealer. Mechanics determined the right trans-axle had separated from the wheel with spindle damage. Initially it was thought that the transmission was damaged, but that may not be the case.

Shift does not appear on dashboard, transmission shifts hard when this happens. When in reverse, the camera does not work. Have to shut car off then transmission works.

I should start by stating that this has been an ongoing issue with this vehicle since I got it last year. At random times, while driving, my vehicle will not allow me to go above 2500K rpms, even with the gas pedal fully depressed. This may happen while I am on a slow road or, as today, when I am on the highway. It is a safety concern because I will need to merge onto the highway or speed up for some other reason and suddenly I have no power. I will be going 30mph and entering a 70mph roadway. The only way to stop this is to pull over, turn the vehicle off, and then turn it back on. I have taken it to my Hyundai dealer multiple times and they have been unable to fix it or address it in any way whatsoever. It is a huge safety issue that they will not address.

  • Automatic transmission
  • 2,500 miles
This car has an automatic transmission and it pulls out of park very easily with no key in the ignition or foot on the brake. This led to my car rolling down a hill and hitting a tree with no one in the drivers seat. When I went to the dealer they tried this on another car in the lot and it did the same thing. I was told by Hyundai corporate offices that this is a "campaign" item. I can not find this problem listed and I think it should be addressed before it leads to injury or death.

A police report was filed and no injuries were reported. The vehicle was taken to the dealer who was unable to diagnose the failure until the other damages had been repaired. The manufacturer was made aware of the failure who did not offer any assistance. The vehicle was not repaired. The failure mileage was 700 and the current mileage was 950.

Brand new car- a few days after purchasing and driving the car, noticed car was not driving right. Several symptoms became noticeable. Car would jerk when accelerating and braking. Cars pick up was delayed and had a very uncomfortable vibration, while in idle and while driving, to the point of getting nauseous while driving in the car. Took car to Hyundai service and told them of symptoms and my concerns of something not right with the car. The mechanics felt the problems I explained above and said something was wrong, now had to figure out what exactly. Several tests were done on the car but nothing showed up on electrical grid. Service had to call a higher tech out in California to see what to do next. California tech made them run several tests, all this took more then 2 weeks until they finally figured out that the engines throttle assy was defective and not functioning properly. They said that this also caused the sensor to malfunction. They replaced the throttle assy and claim the car is repaired. No longer trust car is safe to drive due to the electrical and engine defects that where found after the original inspections by the manufacture and the dealership failed to find these defects with the car and sold it.
