When the temperature outside is high (upper 90s and more), after coming to a stop or slowing down, the engine seizes. It seems the engine doesn't engage or the transfer from the battery to the engine power doesn't engage or something. Also sometimes when coming to a stop and the brake is engaged, the car lurches forward like it won't stop. This started last summer and I took it in and they worked on it and it was better for a little while, not completely fixed, but now it has started again (with the heat) and it is worse than before.

I bought this 2013 hybrid new about 6 months ago. There are 2 main issues I have had with the car. First: the problem is the car sometimes goes about 3 MPH for approximately 25 feet before lurching with great acceleration. I drove with the 'energy flow' mode on the display to see what was showing when this problem was occurring. According to the owner's manual the display was showing the "engine generation/motor drive" (to decelerate the vehicle, engine braking is used while the regenerative braking is applied and also charges the hybrid battery. [engine>battery>wheel]). This sounds like a deceleration mode, but should this be happening when my foot is pressing the gas pedal? It has occurred when I have slowed to make a left turn and also when accelerating from a dead stop. It happens when I am applying steady pressure or pumping the pedal. This can be a huge potential problem/accident waiting to happen if I am attempting to turn or cross a road with oncoming traffic because I may not be moving fast enough to cross before the traffic gets to me. Even if they were over a hundred feet away when I started the turn/to cross the intersection. Second: as has been previously mentioned by others, there is a 'thump' felt at times while braking. It is felt in the driver's seat and through the brake pedal and also felt by the passenger's through their seats. The best way to describe it would be the feeling of being rear-ended and pushed forward several inches. As driver, my head is usually an inch or two away from the head rest and when this happens my head hits the headrest or the headrest hits my head. The brake pedal itself is not affected, as there is no feeling of losing the brake/not slowing down. It's just a 'thump' felt.

The vehicle lurches forward during deceleration thus pulling pressure off of the brake pedal and causing you to put even more pressure on the brakes to compensate. Vehicle will slide on icy roads at this point. Vehicle also has little to no acceleration on electric motor after the vehicle is hot. Making a left turn from a stop with oncoming traffic is hazardous since the vehicle can take up to 7 seconds before it accelerates enough to complete the turn and clear the oncoming lane. Both problems seem related. The first would appear to be free wheeling with no engine type braking applied while switching from engine to electric. The second would be from no electric motor engagement during initial acceleration from a stop or slow to turn maneuver.

27 dec 2013: hybrid battery drained without any warning and car could not be accelerated more than 20 miles/hr while driving. Eventually the car stopped on the road. Dashboard showed "park safely and do not drive" with loud beeping warning sound. Turned off and restarted the car, the engine wouldn't charge the battery. After towing to the service, the car started as normal; the tech could not duplicate the problem so nothing was done. 16 jan 2014: the same problem happened while driving. After I parked the car on the side of the road, the hybrid battery started to recharge to a quarter strength on the dashboard; started to drive again and car jerked twice without being able to accelerate more than 30 miles/hr and eventually had to stop the car on the side of the road. The engine would not start again and same warning on my dash. After being towed to the dealer again, the tech could not duplicate the case; suspected the computer system problem and changed bms control module.4 feb 2014: similar situation. Hybrid battery would not charge more than 1-quarter and the car would not accelerate more than 35 m/hr obtained a case number from hyundai and identified a possible problem of the hybrid battery by the engineer. New hybrid battery was installed.14 feb 2014: started the car, the main screen showed discharge warning for a few seconds then the car runs normal. Turned off the car and tried to restart, the engine wouldn't start. After a couple hours, the car seems to running normal.the problem: hyundai seems to give us an answer 'we cannot duplicate the problem, therefore keep driving it until it happens again. This is a lemon and hyundai needs to accept it and negotiate with us to make things right. I do want to say that the local dealership should be commended on their service, its the management above them that needs to get things done.
