POWER TRAIN
7 NHTSA complaints · 2018-08 → 2025-07
“Lots of indecision with the car about whether to upshift or downshift. Sometimes violent jerking back and forth. Normally. Especially bad between 4th and 5th and 5th and 6th in the upper gears”
“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”
“When the car reaches a certain speed (50 mph plus) it jerks and jolts. The engine light is on and a P-code is present. Each mechanic says something different”
