At railway parking lot, first car blocked when backing out of space. After 3 tries, able to move on, exiting lot and about to turn right into street, car swerved hard right by itself and loudly hit curb. Passenger side wheel and tire totally damaged. I had to get it towed to collision shop. It is still at the shop where am told repair at minimum will cost over $ 1400.00! I found 2 recalls emails that same night and trul Y believe the car malfunctioned. Am just thankful no one was involved but me. Could have been dramatic if car was on the road and malfunction made me hit another vehicle instead of a curb. Have had to rent a car, and cost is mounting. Found thru online research that other Spark owners had same problem. This could cause fatal accident. Even when fixed, I will be petrified to drive this car again with fear of recurrence of same problem.

The following has now happened on 3 separate occasions when driving on a highway: When driving at highway speeds (50 -55 mph) and hitting a bump that jolts the car (not necessarilly a huge bump), the entire engine and electrical system cuts off and shuts down. This happens only on the highway and has not happened on street driving yet. The car power turns off and this can be very disorienting to an unskilled driver. It requires that I put my car in neutral (my car is a stick shift), turn off the ignition and then turn it on and restart it, while moving at 55mph at night on a wet highway. The last time this happened it was at night and raining. This has happened 3 times over the past 6 months.

There was a recall for the Chevy Spark to reprogram the transmission control module, however that does not fix the problem. It does not need to be reprogrammed, because all that did was leave the check engine light on. They have fault control modules. My car is 3 years old and nothing but issues fixing this. The dealerships say that they fixed the recall by reprogramming it, but the light stays on, the rpms drop suddenly and cause the car to jerk when you try to give it gas. This needs to be looked into further. I would never recommend thus car to anyone I know, much less now I'm trying to get rid of it because of the transmission issue

We purchased a 2017 Chevy Spark with 40,000 miles on it and within the first two weeks the car will not accelerate for about 2 seconds and then will leap forward. When you come to a complete stop the engine will rev up and not go forward for about 2-3 seconds. This becomes very un safe since you can not depend on this vehicle to go forward when needed. I have taken it back to the dealer and they said there was an software upload to the transmission that should help. It did not help and I have researched that this is pretty common with these cvt transmissions. I will take it in again this week for them to possibly change out transmission. The complaints that are on this vehicle are the same having to do with acceleration problems. GM needs to look at this issue as a recall to help save lives.
