   Left turn signal can activate by itself after right turn. Details: Driving and making a right turn with the right turn signal active, after the turn when the signal cancels, the signal sometimes activates the left blink-to-pass feature causing the left signal to blink 3 times. This appears to be because the turn signal arm falls too hard. When turning onto a multi lane road this causes confusion to drivers coming up behind where they think I am moving into the left lane, but…

   After getting the recall repaired (which I was never informed of and I had the parking brake engage as I was travelling 30 mph causing me to skid down the road) I got the vehicle back and the very next day it was the same issue and the abs and traction control light came on and it began making loud clicking noises every time I would engage the brake.

   The right side tail signal light module needs to be replaced. I was having intermittent issues with the right turn signal, I took the car to the dealership and they told me that the module needed to be replaced. The car has been in the dealership since March 19th, more than a month ago waiting for the part. I contacted Chevrolet and they keep telling me that no ETA for part is available, and they do not provide any more details on what is causing this delay.

Thankfully, there were no other vehicles involved. The dealership as well as GM were notified of…

    I’ve had intermittent issues where the one pedal driving feature would disable itself. Last night I narrowly avoided a T-bone collision as the OPD deactivated and as I approached a junction it took me a second to realize the car was not stopping and it was only by sheer luck that the other vehicle stopped abruptly so we didn’t collide.
