I have a 2017 Volt and the lock on every door has failed. I had the front door lock replaced at a cost of $500. Each door is the same cost. If I have passengers I have to open the doors from the inside to use them. I am waiting for a recall. This is ridiculous. Also had to replace a bad sensor under the dash that took out the infotainment screen for $1000. Other than that I love the car but it will probably be my last GM purchase.
