UPDATE: Transmission problem NOT resolved by gasoline change. Tranny got worse and almost rear-ended when it hesitated to pull into moving traffic. Dealerships either denied problem (played dumb) or acknowledged and said there was no solution. After a near collision, I traded it in (took a huge loss of $$) and bought a new Ford C-Max. The C-Max (also having a CVT transmission) runs smooth as silk, accelerates without an ounce of hesitation, gets better MPG, more room, and much better build quality. Good trade, though too bad about the transmission on the Spark as otherwise, I like the car as a commuter vehicle and the inexpensive price. Don't know if this problem has been resolved on later models as I've not been following this since getting the C-Max.
After numerous trips to 3 different Chevy dealerships to fix horrendous hesitation issues that appeared to be associated with the lousy CVT transmission, and almost getting hit trying to pull out into traffic, I got rid of this car for safety reasons. The Good: roomy for a little car, comfortable overall, fun handling, nice stereo unit/Bluetooth, flat-folding rear seat. The Bad: TRANSMISSION PROBLEMS, driveability was scary and got worse as time went on, Chevy dealers cannot fix their own cars (no more GM vehicles for me!), paint scratched easily. I would have kept the car if Chevy would have fixed the problem instead of stupid remarks like, "yeah, I've heard that from other people..." when discussing the horrendous driving characteristics. No one seemed to know what to do... so traded it for a loss for a Ford C-Max. Have now over 15,000 miles on the C-Max, getting better MPG than the Spark (avg. 45.5 MPG mixed driving with a/c on), never returned for any repairs or problems... reliable, comfortable, roomy, handles nice (except large turning radius, but can't have it all), great voice-activated radio/nav., very happy with the Ford!
I've had the car for a few months and put almost three thousand miles on it. I tried the automatic but man, was it lousy. Floorin' it and nothin'. The manual though, fun stuff. I feel like a kid again with my go cart. It's no frills like my go cart but it has AC (not the best but I don't live in Phoenix so whatevs). The sound system ain't that great but I don't care. I got it super cheap and brand new. I love zippin' around town in it. Recently I drove it into the mountains and it was fun! I can imagine the automatic would have sucked up there though.
I thoroughly enjoy the interior cloth or whatever it is.
Best of all, 38.5 MPG in town.
Still love this car. No repairs have been needed. The MPG's have only improved and right now I'm sitting at about 40.5 average.
I test drove a 2014 Spark at my local dealership, I noticed the "check engine" light was on when the salesman and I returned to the dealership.
I like the car's build so I purchased another Spark, one with more up grades on it, It had only 11 miles on it.
I bought the car and after just 3 1/2 weeks, the "Check Engine" light came on in my new Spark while on my way home from work white smoke poured out from under the bottom of the car.
I am very disappointed because I was so proud of my little car.
I am in a rental waiting on GM to send a new motor
This car is a complete piece of junk. There have been at least 4 recalls since I got it. It's had problems from the A/C compressor needing to be replaced, to the coolant compartment needing replacement because it cracked from the heat due to being made out of plastic!! The battery needed replacement during the first 6 months of purchase and now I'm having transmission and acceleration issues that are serious. If you look http://www-odi.nhtsa.dot.gov/owners/SearchSafetyIssues you'll see how dangerous this car is and GM is going to have a serious lawsuit on their hands if anyone gets seriously injured.
