There is a problem with the passenger presence module according to our mechanic. When an adult is seated in the passenger seat with the car turned on and stationary, sometimes, the airbag system does not turn on as if it does not recognize a person there. If the car is then put into drive, the airbag system still remains off. Other times, the air bag system will turn on at the beginning of the drive and then turn off randomly during the drive while someone is still sitting in the passenger seat. This seems to be an obvious issue as the airbag may not activate in an accident when there is indeed someone in the passenger seat.

Vehicle alarm sounding. With all doors shut properly. I push the lock door control on the key 2x to enable the horn to sound indicating the vehicle is locked and secured with alarm as it should. As of 28 oct 2015 I do the same and now alarm is going off as if a door is open or someone is breaking in. All fuses have been checked and are good. Vehicle is parked in garage on level surface. Checked with both car keys to make sure it wasn't a key electrical issue. The red signal light in the car indicating alarm is on flashes more brightly than usual. I would like to be able to secure my vehicle. Thank you for you time.

The driver, and front passenger interior door handles the metallic chrome coating starts to lose its adhesive. When opening the door from the inside it cuts your hands if you don't notice it.

I have had my vehicle in the shop multiple times since I had it. First there was a smell of coolant in the cabin. Although misdiagnosed initially, the meachanic later found that there was truly an issue with the car. But in the last year I have had to have the thermostat replaced, the housing of something was replaced a month later (I do not remember the name of the part). And a third repair was also done. All for thecoolant that continues to find a way toleak out. Now I am being told again, by the dealer, that the coolant is leaking again, this time from the water pump. I have paid a nice chunk of change to and being told I need to spend yet another $400+. I have owned many cars and never had this issue. I was also told by the dealer that many people with sonics are having the issues with

I have a 2015 Chevrolet sonic. Every time I've been into the Chevrolet service center to have the oil changed, the Chevrolet service center underinflates my tires. The Chevrolet manufacturer calls for 38 PSI in all four tires. The Chevrolet service center sets the PSI in all four tires at 35 PSI. Now, I'm questioning all oil and lube service centers. Are they also underinflating tires? This happened last about 7 months ago. I've used three different service centers since I"ve owned the car. Service centers in wichita, ks; oklahoma city, ok; gulfport, ms.
