The vehicle experiences intermittent loss of power and unstable acceleration while driving at normal speeds (approximately 45–55 mph). The vehicle will surge, hesitate, and fail to maintain consistent speed, creating an unsafe condition in traffic. While driving, the vehicle does not consistently respond to throttle input and may unexpectedly lose acceleration. This creates a risk of being rear-ended or being unable to safely merge into traffic. The condition occurs during normal driving and has progressively worsened over time. Diagnostic testing indicates transmission-related faults involving pressure control and internal speed monitoring. This issue affects the safe operation of the vehicle and appears consistent with known transmission problems reported for this vehicle model. Supporting documentation has been provided, including manufacturer service program records indicating this vehicle was previously subject to a known transmission-related defect condition.

Transmission failing - when stopped and trying to go from a dead stop the car will not move for a minute the rpm's rev high and the car will barely move maybe two to five miles per hour while the rpm's just rev higher. When climbing a hill the car seems to lose power and not shift like it should. If starting in morning the car may shift for a few minutes then it seems to only shift like downshifting. Other times it seems to run ok and shift ok but the next time you could be trying to merge on the freeway and the car will not go will not get up speed. This dangerous when entering a freeway and trying to get speed up to match vehicles on freeway already. It is also dangerous when making left turns without shifting correctly and car just has little movement revs the rpm's but doesn't move enough to make the turn safely I front of other vehicle waiting to start forward on the green light. It is also dangerous when climbing a hill. I was stopped at a red light when light turned green I pressed the gas and car would not move at all. I continued to let off the gas then press the gas to.get movement to get to side of the road. I haven't been able to drive my car for the last 3 months. I just bought the car less thena year ago and am still paying my payments even though I am unable to drive the car. I really do like this car but have since read of the past transmission recalls on the same year and model and make. I love called Chevrolet asking about the problem and they just tell me my car does not have a recall for the transmission according to the vin. How can my car be failing like many others of the same year that have been able to get repaired under the transmission recall and yet Chevrolet can tell me that my car does not have a recall for the same exact issues I've read about on this site. I am angry because how do the makers tell me my car isn't on that recall for this problem when there seems to be many of the same car having the issue and gets the issue fixed ?

When accelerating (between 5-30mph), the vehicle stutters to gain power/speed-it almost feels like there's a delay in the execution when trying to accelerate. The vehicle will then lunge forward, then sulk back as if the engine has temporarily lost power. The lunge, sulk back and stutter are progressively worsening, to the point that the plunge and sulk are occurring at more varying speed changes more and more frequently (accelerating or lifting off the gas peddle to slow down).

The jug that holds my antifreeze developed a hole right where the hose connects to it and antifreeze was dripping onto a belt. My car would make a screeching sound and hesitate while I was driving. I replaced the belt but then other stuff started going wrong. The engine revs up while I am driving and the car will hesitate each time this happens, it usually happens several times in a few seconds then drives fine for a short while. No pattern, just happens randomly. This has been going on for a couple of months. On 08/07/1019 I was driving 320 miles to copperas cove, tx from lubbock,tx . After driving about 100 miles my car studdered real bad and I lost all power as I turned a corner. Then the check engine light came on. I stepped on the gas to the floor and my car would barley move. I managed to get to a gas station where I had to wait for a tow back to lubbock. Something about the device that puts oxygen into the gas as it goes into the engine is not working properly. I found several complaints about the same experience online. I only have about 54000 miles on my car. My alarm goes off 99% of the time if I lock my car, and my windshield wiper fluid does not dispense.

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.

On 17 sep 2018 while going 60 MPH on I-65, the vehicle started beeping, the check engine light started flashing, the doors started locking and unlocking on their own, the fuel gauge went from half a tank to empty and the vehicle started to lose power. Pressing the gas would not make the car go faster; my car slowed to 40 MPH and stayed at that speed for two minutes and then lost power completely. I had to cut over to the side of the road to prevent myself from getting into a serious accident (an idle car on an eight lane interstate would not have been a good time), turned the vehicle off and then waited 5 minutes. I turned the vehicle back on, and it ran for an additional five minutes before having the same symptoms. Repeat one more time and I was able to make it home safely. The next day, 18 sep 2018, I had it towed to my mechanic who said that based on odb2 scan on the vehicle that the engine computer wasn't talking to any of the other systems and that they couldn't fix this problem; it had to be taken to a dealership. The dealership said they have to run a wire trace to figure out which wire is shorting out the system.

From may 2015 to sept. 2015, my vehicle high-revved and died on the highway three times... The same three lights would come on: traction control, check engine, reduced engine power. Due to the timing of incidents, autonation refused to accept the vehicle although it was warrantied. I called gm corporate and explained that this was a danger to the safety of others and jeopardized my life, and they made attempts to remedy the situation at hand.. Autonation called and apologized for the lack of customer service, but they did not schedule an appointment to find the problem. On a day off from work, I took it to the same autonation to have them run diagnostics, and the turned me away. This happened a document three times. I took it to another chevy house, and they also refused the car. Driving it endangered my life as well as other drivers. Fast forward a couple months, I find out the throttle body is bad, and no recall has been put out. On a separate occasion, condensation had begun on the interior of my vehicle. Upon further inspection, my floorboards were sopping wet, and water began to fill the cab of my car. Autonation did find that a hose had been cut and had been leaking fluid throughout the cab. Today, 2-9-16 at appx. 0426, my vehicle began filling the cab with noxious fumes and smoking upon parking from underneath the hood for no obvious reason. No lights or chimes initiated inside the vehicle. This vehicle could have set fire at any moment had I kept driving. This vehicle is very dangerous to myself and those around, and no one at autonation takes it seriously. I hope by advancing my problems with the 2014 chevy spark will steer potential buyers the other way, and I also hope that gm will do the right thing and buy the car back. When a car dies on the most dangerous highway in texas for no reason and starts smoking, there is obviously something wrong.

Hello, below is an email detailing the issue I sent to hertz which I rented the car from hello, as a reoccurring hertz customer, I wanted to make hertz aware of a severe safety issue with a chevrolet spark that I recently rented. While on I-95 in connecticut, the car turned off completely and I lost power steering and power brakes. I was able to safely pull over and restart the car. If I as a driver had anything to do with the car turning off, the only logical explanation is that my knee touched the keychain which caused the key in the ignition to turn off. Such a light tap of my right knee while I am driving to potentially be the reason a car turns off is of great concern. I would like to keep renting with hertz but this incident has damaged my respect for hertz rented vehicles. Because of this incident, I would appreciate hertz inspecting this vehicle and providing reimbursement and other relief.
