When I put the car in drive today, after having an ECM update at the dealership 2 days prior, the car went backwards down an incline and would not proceed forward.

Purchased car on 5/5/2012 with 6 miles on it. Within less than a week and 200 miles the transmission began clicking. Took it into Hyundai and they stated it needed a new transmission. After 2 1/2 weeks the transmission was replaced as Hyundai refused to give me a different car. Since then the car cannot accelerate, sounds "clunky" and when going at low speeds sounds like the gear isn't engaging and sounds/feels like it would if you released a clutch too early. Car loses power and sounds like it's about to die. A hissing and rattling sound under the hood happens as well. After taking it in to dealer, dealer states they could not find the sounds or noises or loss of power I was having. Rpms rev really high before engaging in first gear. Dealer still won't do anything since they can't diagnose it. I have almost been in multiple accidents for failure of power and car not accelerating. Takes about 3-5 seconds before it goes. Brakes grab too easily as well. Loss of gas mileage (around 6-7 mpg) was reported to dealer but dealer told me it was due to "winter gas." I can understand 2-3 mpg difference but 6-7 is too much. Car has also been in the shop for a week for the car alarm going off constantly for no reason. A piece of the windshield plastic also fell off for no reason when car was 3 weeks old. Dealer duct taped that part down until a new part could be ordered.

Bought the car brand new in Jan of 2012, started having "issues" with the duel clutch within a few months of driving. After getting use to the new car and how it drove, putting a few thousand miles on the car, something was still not right with how it drove. Not getting the speed it needed and tacking out the rpms to change into the right gear and at times, was the wrong gear. We had taken it to the dealership in which we got the car, told them of the issue and they said there was nothing wrong and that it was "normal" with the duel clutch and that we had to drive it more in manual mode, which made no sense to me. After a few months, the car got progressively worse....could not even merge out into traffic that was going 30-35 mph. Had to always drive the car in manual mode as opposed to automatic, adhering to the dealership. Well, one thing lead to another and now the car is barely driving and becoming a massive safety issue, as we have to use this car to go to and from work and that only. We had brought it to the attention of the dealership, once again in Dec and now... they are having "issues" with the duel clutch and that this car was...a "guinea pig" and being made a complete mockery of this particular dealership. We have escalated the issue to corporate office and I will never purchase another vehicle from this maker ever again... nothing but a horrid experience.

The car does not accelerate properly. When at a full stop and I press on the gas the car does not move however, the rpms are high but the car takes 5-6 seconds to go and it doesn't go very fast and there have been times I was almost hit. My car jerks when I try to accelerate from a slow speed, it is the same movement as if you were running out of gas and actually jerks my neck. My rear driver's window shattered for no reason. It was in the drive way and when I went out to work in the morning, it was shattered. There is no impact sight as evidence that something had hit it. I am very unhappy with the car and wish I never bought it.

Vehicle downshifts to fifth gear when passing but does not return to sixth gear upon releasing accelerator. Vehicle continues at same rate of speed when releasing accelerator as if it were on cruise control. While passing an 18 wheeler on hwy 169 North, I noticed that there was another 18 wheeler approximately 100 feet in front of the one I was passing. With an oncoming vehicle I could not pass both trucks, so I passed the first one and pulled in behind the other one. When I let off the accelerator, the car continued at the same rate of speed forcing me to slam on the brakes to avoid rear-ending the other truck. This vehicle (and subsequently another vehicle on the dealership lot) exhibits this characteristic every time the vehicle goes into passing mode. However, if you back off the accelerator slightly, after about 5 seconds, the car will shift back into sixth gear [but all the while accelerating]. I noticed that you can manually shift the vehicle back to sixth by moving the shifter to manual mode for a split second and then shifting back into "D". the engine rpms will fall back down immediately indicating the shift. Otherwise, the vehicle remains in fifth gear without decelerating for approximately 8 seconds. In my case, the car did not do what I "told" it to do: Decelerate by releasing the pedal. I've spoken to Hyundai and to the dealership and have filed a complaint with the better business bureau because of this design flaw. "control" is the key issue behind the wheel of a vehicle. If someone is not expecting the vehicle to continue at the rate of speed when they let off the accelerator, they could crash into someone as I almost did. Thank you.

Original email sent to Hyundai motors usa "dear Hyundai motors usa, I have visited the dealership with my new Veloster for two issues on the car. I was advised to contact you to open a case as the dealer would not attempt to fix the issues as there is no recalls or service bulletins. Here are the following problems I have notified the D ealer of and those that need to be fixed. 1) serious issue! when braking under heavy conditions, both ABS and non ABS cases, the car swerves and/or loses it's 'rear' to either left or right. I've braked hard several times and it feels like the rear end is giving out. During ABS conditions, the car swerves like it's a rwd driven vehicle. This is not only scary as a consumer but dangerous to others. If there is any condensation on the road while braking and the leaning to one side occurs and/or swerving, I could hydroplane and cause a major accident because of a mechanical defect. I have done my own research and spoken to other Veloster owners as well. They have mentioned they have the same problem and their dealer has ordered and replaced one of the rear brake calipers to solve the problem. I informed my service advisor & the mechanic of this issue on 3 separate test drives. 1 test drive with service advisor in my Veloster, 1 with the mechanic in my Veloster & 1 in another new Veloster with the mechanic. In all cases the vehicle swerved or felt like the rear end was coming lose. Please have this issue fixed and provide customer service. I was very disappointed to learn that I have to write you prior to the dealer servicing my vehicle. I will be cooperative in this issue and look forward to a solution.
