“Gas pedal has lag to it. Almost every time you go to take off sometime it doesn't respond till your quarter way into pushing petal must push petal farther in before it will accelerate causing it to jerk hard. My friend has same car and problem also servos in dash for heater keep clicking and malfunctioning after multiple replacements, my other friends 2010 Impala does this as well.”
NHTSA complaint #11402517, filed 2021-03, 180,000 miles“Loud clicking noise. I think it's somethings to deal with the air conditioner when the button is on the blue area. Actuator? The clicking sound would come and go. When I press the key button on my keychain. Pop the trunk and sometimes it just goes off through the the day when the car is off and park.”

I have read online where people have crashed from this I feel Chevrolet needs to do a recall. I live in atlanta and if my car reduces speed while I'm on 285 this could potentially cause I very bad crash.”
