The problem I am having with my vehicle is that the engine stopped while I was driving down the road without any warnings at all. There was no check engine lights, no oil lights, or any sensors that popped up for that issue. This has been a known problem after doing some research with this engine. I had it towed to an independent mechanic who diagnosed him with a engine problem and said the engine needed to be replaced. I had it then towed to a dealership Hyundai dealership and they have had my car for a week without giving me any information on what is actually wrong with the engine. I cannot receive a loaner car because it is out of warranty and my aftermarket warranty is still trying to investigate what is wrong with the engine and no one else is helping me. I've been out of work now for almost 2 weeks with no vehicle no explanation, but yet there are numerous complaints all throughout the internet about the engine for this vehicle. There is no engine available anywhere for this vehicle probably because of the known issue. They are telling me they will have to order it piece by piece if the warranty will cover it. I personally think there should be an inspection on these engines and a recall done because what has happened to me has been happening for years since the vehicle has at the market. I have read over 30 different complaints about the engine just dying and seizing while driving the car.

This has happened many times since I purchased the veh. In 2016, with 16,000 + or - miles on the odo. When I turn off the "eco" mode, the problem still happens, though not as often. I left the car at vandergriff Hyundai for a day with N.P.F.

2015 Tucson engine blew after only 70,000 miles. It did not show any signs of failure but as I was driving the engine made a bang noise and just stopped and would not start again. After I did some research I found out that this is not the first Tucson to have engine failure after 70,000 miles.

- Brick, NJ, USA

I was taking left into my drive, in front of oncoming traffic, the engine sounded like it was revving, but I had absolute no power. Luckily I got enough power eventually to get into the driveway without getting hit. I have had this happen repeatedly in this car. It has been into the deal once and they said they updated the software but it has started happening again. This is so dangerous. I never know exactly what I'm going to get when I step on the gas. The dual action clutch is awful and I was not informed about it even having this when I bought it. Otherwise, I would not have bought it.

- Miami, FL, USA

When taking corners in the city I can't accelerate the car just revs for about 15-30 seconds and won't move. I have to try to pull over to get off the road. Also when accelerating from a stop the RPM's like to shoot up but the car won't take no gas. I have almost been hit twice because of this problem. Hyundai just says learn how to drive it. Learn what how to stall?

I purchased this car November 8 2014 with 99 miles on it. We've had severe issues with it in the last year. We've had it to the dealership where we purchased the vehicle and they've been in communication with Hyundai in order to fix it. There was no solutions, just "try this & see if it works." In July 2016 I started having medical issues, we've had issues with the vehicle not wanting to start. At first it wasn't wanting to start & then the check engine light came on. We took it to our local dealership and there was a recall on it for the exhaust system, they claimed that was the issue. So that recall was preformed and the light went off. Low and behold the issue was not corrected, the car still had episodes where it would not start. The issue was not something the service department could re-create. Second trip to the dealership for the same issue and they replaced the inhibitor switch, and that also has not worked. Now the check engine light is on again but the code is coming back as the purge valve. The car currently has no power and feels as if the motor could die at any second. I travel away about twice a month for various specialist doctor appointments. My vehicle has left me stranded there several times. I no longer feel my vehicle is safe or dependable for myself or any of my 3 children to be transported in it. I have contacted the Hyundai company directly but no response from them as of yet. For a 2015 model vehicle this may issues is ridiculous!! my husband and I are very disappointed and will never own another Hyundai vehicle!
