My 2016 Chevy Sonic seems like someone is tapping the brakes on and off from when it hits 26 mph down to about 18 mph and then it stops. It goes in and out about 5-6 times while coasting. I think I feel it a little even when I’m braking throughout those speeds as well. Any ideas what could be causing that to happen?
P.S. The ABS light came on when driving it earlier today for a little while and then turned off. Thinking it could possibly be related.
P.S.S I just drove it and I noticed that the RPM when coasting jumps from 1,000 to about 1,200 when the “braking” feeling starts and goes back down when it feels like it’s being released.
Likely a stability control problem. A bad sensor or a weak battery can confuse the stability control into thinking you are ready to spin out so it applies the brakes. A tech needs to ride with you with a scanner connected to the car’s ABS system to read what is happening when it occurs - as well as read out any error codes the systems have stored.
Modern, computer age cars are easy to diagnose if you have the tools and the smarts to interpret the data.
Wow! 36 month 36,000 mile warranty on a 2016! I checked and it was the same for 2018 GM vehicles! Warranty is a huge selling point indicating the manufacturer’s confidence in their product. My 2010 Kia and it’s cousin Hyundai have 60 month/60,000 mile standard warranties and 10 year/100,000 mile powertrain. I guess GM is counting on being bailed out as many times as needed.
