2015 Chevy Spark- RPMs Jump, Squeals and Jerks

40

Asked by LilSpark Mar 27, 2018 at 09:51 AM about the 2015 Chevrolet Spark

Question type: Maintenance & Repair

Hi!

Around 8 months ago, I noticed that when I would be about 45 minutes into a
trip (highway speeds), my Spark's RPMs would suddenly jump (usually from
about 2000 to 5000, without any prompting (foot at a consistent pressure on
the gas pedal), it would make a squealing sort of sound and would slightly
jerk. At first, it would only do it occasionally and once during a trip- making it
seem almost as if it were a fluke. Over time, it started to do it multiple times
in a row, usually 6-8, and, once done, would be smooth sailing for the rest of
the ride. That said, during that little sprint of it, I had the feeling that it could
almost lose power at any moment.

I have brought it to the attention of my Chevy dealer (even providing them a
video of the dash when it occurs)- I bought every warranty that I could, in the
case that it needed repairs, but because the check engine light isn't on, they
tell me that they can't figure out what is wrong with it, since the computer
won't pick it up. Because it has been going on for so long, my getting closer
and closer to my extended power train warranty running out- which will be
absolutely terrible if it does run out and that was the issue.

Over the course of the last week and a half, it has become even worse-
beginning about twenty minutes into my drive. I have noticed that it seems to
be occurring more and more as I am accelerating (it occurs so much during it
that I'm barely able to get up to speed). It will level off for a minute or two,
then, once again, do it almost non-stop.

Has anyone ever experienced this? Or have any suggestions as to what may
be occurring? Thanks so much!

Thanks for answering my question. How did you find out it was your transmission? I’ve heard the transmission on these cars are not that great.

Look up all the recalls for this vehicle. Ours (2014) burnt oil and had similar symptoms and a free recall made all the difference. It was something like a pvc valve. Best of Luck, Kevin

It is definitely the transmission. I am going through this right now. Powertrain warranty ran out 2 months ago and GM will not cover the $5000 new transmission bill. It only has 69,000 kilometres on it! Disgusting!

Mine did the exact same thing but luckily it was 1 month under the warranty ran out. I only had 80000 miles and the warranty ran out July 14 2020. Talking about luck.... So now i have a brand new transmission. GM gave me a 2 year warranty on the new transmission.

Brought car in to Paul Sadlon Barrie May same problem RPMS to 4000 or 5000 jerking feeling like transmission will fall out. Kept car for the day response "could not duplicate customers concern at this time" invoice statement. Work shift day and night on highway 200km per day. Explained if car breaks down in live lane at 1AM with transporters going 120 to 130 km on highway no lights on this highway my chances to survive would be 0. My husband drove today July 17 2020 to toronto and could not believe that they gave this car in this condition to me he actually said I am scared to drive home. Called them they will check again the car Monday?
