Unknown Regular oil changes, cranked my car up one morning and it started knocking, I have been in a rental for 2 weeks now and paying out pocket as a single mother in grad school. The dealers excuse of not diagnosing the car sooner, is that their schedule is busy after arguing with the extended warranty company about my coverage. I booked their next soonest appointment to be told we'll see if we can get it looked at that day. I believe they're hiding the fact that my bricks falls under recall 198 and do not want to admit it.

Unknown Vehicle stalls and misfires

- Mccomb, MS, USA

When I first bought my car it seemed to have some sort of transmission problem because it's a dual clutch I was told they do have problems sometimes when I'm trying to pick up speed it seems like it won't switch gears so it won't pick up speed which is extremely dangerous especially when I'm on the beltway or highway and I've already had Hyundai replace the first transmission because it was faulty now my second transmission is already acting up and it's only been 2 years

Cruising on freeway ~70 mph when car starts slowing due to lack of power- for unknown reason car went into "limp mode", with turbo boost pressure and power cut off, barely enough power to keep car at 60 mph in order to make it to freeway exit to pull off. This could have caused serious collision. Turned off car, let it sit 1 min, turned it back on, and problem seemed to go away. No Check Engine Light, no OBD2 codes. Limp mode sometimes occur during harsh shifts but releasing throttle and reengaging usually fixes it but this time needed to shut off the car. Has been reported to dealer but they can't reproduce consistently and no CEL/codes so they won't try to find a fix. But losing power for no apparent reason on freeway definitely dangerous situation.

- When it shifts from 1st to 2nd or 2nd to 3rd gear, the RPMs will keep going up until I take my foot off the gas. So if I need to merge onto a highway quickly and it stalls in one gear, it can go up to 6k or 7k RPMs without shifting. I never let it get past it because I take my foot off the gas to let it shift because I'm afraid it will blow something. - When in automatic and at a stop, if you go, it will sometimes rev up a little high before shifting and also pull a lot faster versus other times when it shifts normally. To keep me on my toes, it will sometimes do the opposite and not accelerate very well at all. Almost like I press the gas and nothing happens until it's pressed all the way and then it will go. - The tachometer will lag on what RPM the engine is actually on. So you'll know it's clearly at 3k but it will only read on 1k for a few seconds before quickly going up to what it's supposed to be on. - There's also a knocking noise when my car is idling for a little while. It's every 5 to 10 minutes there's a loud knock coming from the engine. - I also understand when driving slow, for example like a drive-thru, DCT don't typically like that. But when I am in a line like that or traffic, it will stutter as if it's about to stall or shut off completely. And not like a light shake, it was very noticeable that everyone felt as if it was going to sputter and turn off. With these multiple issues, it makes me and my passengers feel extremely unsafe and it's concerning that anytime I've taken it to the dealership it's shrugged off by saying the DCT transmissions sometimes "act weird". I'm not sure how that's an answer to something that is pretty dangerous.

My driveway has a slight incline to get out of and every morning when I start to leave the car will start to jerk- like it isn't gong into gear and i have to back off the gas pedal to stop it. It is hard to describe. But it definitely should not be making that sound. Yes I can take if for inspection. When I am at a stop light or just stopped and whenever I turn the car wants to hesitate and sometimes jerks me. Transmission issue here I believe. About got hit on several times because of the engine not performing when I press the gas. When I drive on the highway for 2-4 hrs, when I get off and stop the car is like it is still on the highway. Meaning when I push on the throttle it takes off. As far as I know, when I take my car to Hyundai for oil changes and maintenance work they haven't inspected my car. Ever since I purchased the car- it has never ran right. Something for sure is wrong with the motor- When I need the turbo to work- it kicks in around 40 mile an hr- not when I put on the gas. The car just runs terrible. There is also a horrible blind spot on both sides where the mirrors are. Horrible.

My car hesitated from a stop sign, then launched forward causing it to uncontrollably jump forward very fast. When I went to hit the brakes they failed to active, and had to pull the E brake. The car has had a software update for the tcm on my dct transmission but the problem seems to not be able to be fixed. This is very dangerous, and could cause a major accident or death.

- Jeffersonville, IN, USA

I was stopped at a stop sign and upon stepping on the gas, I noticed that the car would not accelerate. It was making a humming sound similar to if it were in neutral. I cannot seem to have any power when shifting into sport mode getting onto the highway and does not accelerate at all. It makes an odd noise. I felt car hiccup at first when accelerating. This could be a dct issue and could be safety issue also. Car is at approx 77,000 miles at this time. Similar acceleration issues reported with this vehicle by myself prior although not this severe and sport mode was working fine.

Veloster Hyundai's 7-speed dct contains a design defect in the transmission control module (tcm) that causes, among other problems, failure to shift, stalling, delayed acceleration, or loss of power. 'these conditions are hazardous because they severely affect the driver's ability to control the vehicle during normal driving conditions and prevent drivers from accelerating to maintain safe speeds in traffic, '

I was sitting in a line of cars to get on the freeway I merge into traffic to have the car stumble and jump and wont go, I was almost rear ended when the car decided to take off like a rocket and I almost hit the car in front of me, this has been an ongoing issue since I bought the car new in 2016 and has continued to get worse, this was the first incident about 6 months after I got it, I took it in the dealer, they had a recall and fixed it for a while, then this same thing happens all the time on a daily basis, under normal driving conditions its dangerous because you dont know what the car is or isnt going to do, will it go when I need it to ? or stall thats the huge question, I have had it to the dealer 4 times to have them tell me they all drive like that and they don't know how to fix it or what to do, I have gotten reluctant to drive it only when I have to because im afraid it will stall or leave me stranded, this morning im coming to work and stopped at a sign, then when it was clear I go well no I dont because the car acted like it was stuck, I was in the middle of the street and it finally caught and took off, I am a very cautious driver so all of this happening im extremely careful in heavy traffic, but something has got to be done

Upon turning and going over any kind of significant bumps or uneven surfaces the vehicle fish-tales from the back. I have tried it on different streets to ensure its the same issue and the issue is still present. I almost lost control of the vehicle on the freeway due to a small patch of uneven road. I have driven other vehicles over the same freeway spot to ensure it wast just my vehicle but did not get the same issues as I do with my vehicle. Also when coming to a full and complete stop and then putting my foot on the accelerator to move the vehicle forward the transmission does not engage correctly, either it waits to engage after the car reaches 4,000 RPM or jerks suddenly into gear both occur are on a daily basis. Another key problem with this vehicle happens when taking my foot firmly off the brake and pushing the accelerator on a hill, per the manufacturer the vehicle is suppose to wait about 15-20 seconds on a hill to allow me time to step on the gas to get the vehicle moving and prevent rollback into traffic or obstacles behind me however it is either not working correctly or defective.

While driving home from work, car stalled and would not go over 5 mph. Had vehicle towed to dealership where they diagnosed a failed catalytic converter (19,038 miles). Unit was replaced under warranty. Recently, same exact problem happened again. Driving home from work, stalled, had vehicle towed. Dealership says failed catalytic converter led to lower engine failure. Reported unit under warranty, but would be over a month to get a short block for replacement. After reading about other models with excessive exhaust temps causing failures, I am concerned that this problem is going to reoccur. I have never heard of catalytic converters failing on new cars and certainly not twice with under 30,000 miles on the vehicle. Second failure happened Saturday Feb 16, 2019. Car is still at the dealership.
