Car is now hesitating upon acceleration and sounding louder than usual as well. rpm is not moving up much and harder to speed up, even in sport mode. dangerous when needing to go at relatively high speeds (onto highway onramps etc)
Veloster turbo dct model. when the car isn't fully warmed up, the car suddenly loses power upon medium to hard acceleration. pressing the accelerator increases engine revs and transmission actually shifts, but no power is being put to the wheels. you have to fully lift off the accelerator and then depress again to get power back. for example, accelerating to merge into freeway traffic is dangerous as it loses power as you are merging and could easily be rear ended. or turning left across traffic, if the vehicle loses power mid turn you could be hit by oncoming traffic. happens every time you have medium to hard acceleration when the vehicle isn't fully warmed up. has happened too many times to number. there is video documentation on the internet of same problem.
Car sometimes accelerates by itself even when off the gas and on the brakes. lunges in stop and go traffic. passing gear sometimes revs up to 6500rpm's but stays in the current speed. sometimes car stays at a certain rpm even if not on the gas and wont slow down. bad lag and terrible dead spots in acceleration. i feel like transmission is not communicating well with control module and gas pedal position sensor is way off the mark. car has put me in life threatening situations but hyundai service says they cant reproduce the problem but only drove it 7 miles. i bought car brand new and just turned 5800 miles but has been back for this problem 4 times now.
Accelerating by itself, lunging in stop/go traffic.motor revs into passing gear all the way to 6500 rpm .but stays in the current speed, and sometimes will hold at certain rpm even if not on gas , very laggy in rev i feel i'm driving older car with messed up transmission
The vehicle has failed to perform multiple occasions. take off from a light and about 3rd gear the car will not accelerate but rpms will rise and will go all the way to red line, foot on gas pedal but no correlating acceleration, kicks in moment later with a jerk. car has had two dct updates, one engine update all have not fixed the jerk acceleration and sporadic unableness to get vehicle going but rpms rise. car has gotten stuck in gear when merging onto freeway, the car has had its rpms rise continuous to red line while foot was entirely off the gas pedal then rpms fell and acceleration fucntion resumed. no real help from hyundai as of yet or acknowledgement of a problem. issue has been reported to them since 2016. this issue has also occured on highways while in a higher gear as well as intersections at lower gear. gears shift efforltessly and smooth somedays and eradict and unreliable other days. also has failed to accelerate after red light right turns that could clearly be made, however when the vehicle gets stuck and wont accelerate the risk of getting hit or rear ended is of high probablility and concern. only a matter of time before a serious accident will happen. issue occurs sporadically (avg couple times a month) since june 2016 which makes it hard to duplicate but it occurs and is without a doubt a safety issue and the car is not functioning as designed. proud military family in this our sole vehicle, which is not getting the attention it needs from hyundai in regards to this major safety concern. cant believe they keep sending us off in this death trap saying they updated it and it should fix our issue. they are aware and they do nothing to make progress on this issue or ensure the safety of the families in their vehichles when this particular issue has presented itself in others velosters as well.
