Check Engine Light On problems of the 2014 Chevrolet Spark

While I was driving the car, the check engine light starts comes on, and the car loses its ability to accelerate properly and shakes all over like it's about to fall apart. This is particularly dangerous when I'm on the highway and the car suddenly forces itself to go slower and won't accelerate beyond 25-30 mph.

Car lost power and took longer to accelerate than normal while I was driving it. My car's dashboard showed the check engine light, reduced engine power light and a loss of traction control light. A car diagnostic recommended to change the throttle position sensor which I have done with no success. A dealership diagnostic said there was faulty wiring which would cost $600 to fix. I have not gone through with the repairs as of yet. I have met at least 2 other people that have this problem.

While trying to accelerate from stopped position car will hesitate and stall out. Check engine light came on. Took to dealership and had 1400 misfire codes in history. Has been back to dealership 5 more times and cannot duplicate concern. Now while driving down the highway car has lost acceleration and stalled out a total 4 times in 85 miles. This is a huge safety concern for me. I've been lucky so far to avoid being hit but I shouldn't be playing russian roulette when I'm driving a vehicle with less than 30k miles on it. I've had the car since 12/2016 and it's been a complete nightmare. Gm needs to recall all these cars before a class action lawsuit against them is filed. I'm paying for a car that I am scared to death literally, to die!!!.

The check engine light starts flashing and the traction light comes on, then the car loses its ability to accelerate properly and shakes all over like it's about to fall apart. This is particularly dangerous when I'm on the highway and the car suddenly forces itself to go slower and won't accelerate beyond 20-30 mph if I'm fully revving the engine. It is an unpredictable on and off issue that the dealership has yet to see and is not related to temperature as the issue has occurred in all 4 seasons. As of last week, the acceleration and shaking issues have started occurring without the check engine or traction lights to warn me it's happening again.

I purchased a 2014 chevy Spark on 2-26-2014. 40 hours later the check engine light came on and vehicle was struggling to shift. Returned to dealer and they said that a sensor was not plugged in all the way and the transmission issue was because a new vehicle "needed to be broken in. . . Which takes about 1000 miles). Service manager decided to keep vehicle because transmission didn't seem right. They kept vehicle until 3-7-2014 and still did not shift right. Had 4 days, and check engine light came back on. Returned car to dealership on 3-14-2014 and they had vehicle for 13 days before any contact from them. Called on 3-27-2014 & they stated that they had to change pistons and other engine components and vehicle would not be ready for about a week. To further my suspicion, they want me to come in on 3-28-2014 to sign papers to refinance vehicle from gmac auto finance because they "found a lower interest rate"!! and to further my disgust with this situation, they never sent the payoff to my finance company of the vehicle that I traded in and now they have adversely affected my credit. I have only had possession of this vehicle for 9 days in a 30 day period. Any suggestions??.

24 hours after purchase of a 2014 chevy Spark, the check engine light came on and car is slow to accelerate. The check engine light was not on when arriving at dealership, but the diagnostics showed a knock sensor code. They decided it was a loose gas cap as the vehicle was filled up the night before and they sent me home. The next morning the check engine light came on again. They kept the car for over a week because the knock sensor was on backorder. It was replaced and less than 24 hours later the check engine light was back on. They told me they wanted to replace the engine in a brand new car. I purchased the car 2/2/14. It is now 3/10/14, the car only has 300 miles on it, and has been at the dealer for service 3 times for the same issue. The car has been at the dealer for over 30 days. I am now working with someone from gm and asking them to buy it back from me under the lemon law.
