My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.

Dashboard speed indicator dimming and getting brighter for no reason. no warning lamps. Check engine lamp turned on then after fueling vehicle engine won't start, or won't shut off. Vehicle is an automatic transmission. A button must be engaged to put vehicle in park, drive, etc. The Button often sticks and keys cannot be removed because the transmission won't go in to park. On July 17 the button popped out while driving. This could have stranded myself or my family. The cause of the issue is unknown, but drivers may become distracted when the end of the automatic gear shift lever pops out or as in my case when putting the vehicle into park it pops out and breaks off entirely. I believe it to be a defective part that can easily break. My vehicle has less than 70,000 miles. It has not been assessed by an insurance agent or dealership yet

I purchased my car about a year a half ago and it has been giving me non stop engine and leak issues. I have a 2015 Chevy Sonic turbo and so far I have taken it to the mechanic 8 times to fix coolant leaks, fix my fuel thermostat as well as replace a head gasket after having it blow.

I've realized and noticed in my vehicle; that some things aren't electronic set correct. My air bag light for passenger; does not turn on when I have a passenger. Some days it will be on and other times it will not. My screen glitches here and there and not working correctly even with touch. A few buttons on the steering will are not as well working for some reason. My fuel gage for miles changes and not set up correctly with pump. It will show 280 when full the. Move up maybe 15 minutes later then back down. Not like it was when I first purchase my vehicle.

June 2015 the dealer switched cars when we refused the options at the closing of the deal to a base/standard car. A week or so after purchasing the car a tire popped as we drove down the street. It is very loud in the morning. A high pitched squeaking sound. Next we have been smelling gas, oil/fluid leaking from the car. The driveway is stained from it. The thermostat has been changed 3 times. It has been jerking, stalking, sputtering. The antifreeze reservoir has boiled over several times. It smells like something electrical is burning. The air conditioner doesn't cool well. The windshield wipers tore up in less than a year.thealership doesn't know why these things have happened they want to do maintenancing to see if that fixes it. Over $1000. We got this compact car to save and survive. This has been an expensive cheap car.

Had the car less than 1-week after purchasing "used" with 19K miles.
