When I attempt to start the car the engine turns but won't turn over. The car does this more often in very cold weather. Even in warm weather it will start sometimes and sometimes I have to try multiple times and sometimes it will not start at all. There are no check engine or other indicators that there is an issue with the car. The only other thing that may or may not be related that is different from what I normally expect is that sometimes the while driving, the car will not accelerate in a timely manner. There is a bit of a hesitation as if the fuel output is not increasing. This happens while I'm already driving (for example when I'm going from the access road and entering the highway or when there is a speed limit increase of some kind). I was told by a mechanic that the part affected is connected to other systems in the car that have an electrical component such as the fuel pump.

2/22/2019 car has 55,000 miles but for past year have had problems with braking on uneven surfaces [cracks, potholes] on highway, streets. When braking car feels like you are braking on full metal and bottom of car feels like it is coming apart. Another issue from the beginning of owning the car are issues with car hesitating upon lifting foot from the accelerator. My sister who owns the same car/year, has the same issue. Problems reported: suspension/acceleration.

When I first purchased my car, I was given a different car than the one written down on my paperwork. I had to come back in to get the car that matched my paperwork. Since receiving this car, I noticed a slight hesitation when accelerating. Recently, it has gotten worse to the point where it will jerk repeatedly when I have to constantly accelerate and then break when there is traffic. When I am just driving freely on the highway or side streets, it seems to get stuck in one gear and no matter how hard I push on the gas pedal, it will not go any faster. I have to press extremely hard on the gas to make it go and then it will jerk forward and make a really loud accelerating sound as if I'm a monster truck. This is very unsafe on the road and it makes me nervous to drive it. This car is my only vehicle so I can't afford not to drive it, but I really need something done with this.

This 2016, hyundai elantra sport suffers from dangerous hesitation when accelerating from a stop. This is dangerous because when pulling out into traffic there is an expectation of have acceleration from a stop. This has occurred on numerous occasions since the car was new. I called the dealer about a year ago and asked if there was any transmission reprogramming or anything else the factory had developed to cure this problem they said no. Today it was particularly dangerous when I pulled out and it just would not go for several seconds. Barely missed being involved in a head on collision. I believe it is time this gets reported as a significant safety deficiency. We had bought the "sport" version of the car to get better acceleration from its larger engine, because some owners had complained that it was weak of acceleration, but this did not cure the problem. It is only a problem on accelerating from a stop. Moving acceleration is pretty good.
