Kia Optima Hybrid jerking problems

Filed Aug 10, 2020 · Brakes, Engine · 35,000 miles · MD

My vehicle has had multiple issues with its hybrid battery management system since purchase. It has been towed 4 times. While driving my car will start to jerk and a warning system telling me there is a problem with the battery management system (bms) and the power train. It will tell me to pull over or to contact the service department. This car has had its battery replaced and software upgraded numerous times, but I keep having the same issue. I'm concerned the battery system is faulty and it's dangerous to drive at this point, as nothing preceeds the issues - they happen out of nowhere.

I literally just had my engine replaced (blew in august at 85k miles, dealership had my car for six months while I waited on an engine, cost $7k). I got my car back in mid-february. On march 25th, I was at a stop light, and when I accelerated, the car lagged and lurched forward. This continued any time I shifted into d or r, or came to a complete stop. I was out of town and the car was parked for two weeks. My partner drove it yesterday (4/11/19), checked fluids, and observed the lurch. As he was arriving home, the car lurched to a stop and gave a "hybrid system warning! Safely stop and do not drive! We dropped it at the dealership. I bought the car for $9k, sunk another $7k into the car, and am now expected to pay $5k more on a transmission that didn't have any issues before. Kia has already stated that repairs at their dealerships aren't being performed correctly. This is getting ridiculous. I had to vdeal with massive economic hardship over the six months I didn't have a car, and now its going to start all over again and I will be $20k in the hole on this car. This is not how good, safe vehicles are built.

Engine sounds like it is going to blow up. Valves are very loud and it lurches under acceleration.

At 116,000, while driving in city car would decelerate and jerked "hybrid warning system-do not drive" light came on. When backing out of parking space, car would jerk backwards. Took to dealer who diagnosed that it needed new transmission. Took car to my mechanic who provided better warranty on transmission work. Replacing transmission has not fixed car.

While driving on a 4 lane highway, my car jerked and loss power, going from 60 MPH to 20 MPH. I had the car towed to the dealership and they said a threw an engine rod! The car had 108,189 miles on it. There is a nationwide recall on the kia optima already, but mine is not. It should! The bearing rods go out prematurely and that is exactly what mine did.

When driving my kia, as I approach a stop and the automatic transmission downshifts, the car will lurch forward - almost as if a car is hitting us from behind. It is forceful and happens frequently. Now, after only 5 years of ownership, the car has serious transmission problems. It is no longer safe to drive on the streets.

Over the last month, I have been experiencing many transmission issues where the my 2012 kia optima hybrid is hard shifting between gears 2-3 and 5-6; same when down shifting. I have had to break extra long because of the downshifting, the car 'lurches' forward, and I fail to get sufficient power in the proper gear when I accelerate.

Takata recall--I was involved in a motor vehicle accident with my 2011 kia optima hybrid. As the impact was pretty hard, the air bags did not deploy. My daughter was jerked forward and hit her face on the dashboard.

Approaching a stop light, the automatic transmission started downshifting. As it went through each gear there was a short pause followed by a jerking car motion. Accelerating through the intersection, the engine started to rev like the clutch was out on the transmission. As I was on a busy state highway, this put me in danger of being hit. I managed to pull my car onto a side street, and the transmission continued to behave in this manner. There were no warning lights on the dash, or any sort of indication there was a problem with the car. I put the shifter into manual mode, and found that I could control the gear shifts well enough to get the car to the dealer. After 3 days at the dealer, they tried a reset to the relearn system and updates to the ECM/ecu as suggested by kia. The problem remained. Now they are talking about replacing the transmission, but kia cannot tell them when the transmissions will be available. The dealer has another car that has already been waiting for more than 3 weeks to have the transmission replaced. Failing transmissions are a serious safety issue, and when drivers have no warning that the system is failing it makes it even worse. The lack of available transmissions would indicate to me that they have a known problem that should be investigated.
