I was driving on the highway when my jerked twice, check engine light started blinking, and i could not accelerate. i was able to get off the highway safely, my car was towed to a kia dealership nearby and i was told it could take 3-4 days before my car is looked at. this problem has happened twice while i was on the highway. it happened on october 3rd, my car was towed to a kia dealership and i was told the knocking sensor went out. the issue was supposedly fixed and i picked my car up on october 8th.
On the evening of may 17, i needed a jump after work. i went home, turned off my car but was unable to start it again so i replaced the battery. i thought i had fixed the problem until the next day when i was driving 65mph on a local interstate with my daughter in the car, all my dash lights came on, i lost navigation & radio and my power steering locked up. i went to turn on my hazards and those did not work either. i checked my mirrors to make sure no one was going to hit me and i was able to get off the highway and pull onto the shoulder. i was extremely fearful as i had minimal steering capability & was unable to notify other motorists of my disabled vehicle as my hazard lights were not functioning. i was able to get it towed to a dealership where i was told i needed a new alternator for my 3 year old car. while my mileage was at 66,500 miles, i definitely had not anticipated need to replace that part of a while. despite that, i was more upset that i lost function of my car and was not able to warn other cars with working hazard lights.
Intermittently car will shudder (jerk forward and slow, jerk forward and slow) many times when accelerating, either from a stop or while accelerating from low speeds (less than 45mph) it seems possible gear changing is not smooth. and can be dangerous when attempting to merge into traffic as car does not accelerate as it should. have taken the car to kia who report that nothing was wrong with car when they test drove it. problem seems worse when it is hot or cold outside.
The car stumbles to start and when i accelerate it flutters until picking up speed. this happened on highway 43.
