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 the cooling system. I asked about a recall and he told me to make a complaint. Whenever the issue arises again there is always a strong smell of coolant in the cabin of the car. Then the car stops blowing heat and air, or blows it intermittently.

I've had several issues with the car. The main one being that my engine has warped and the car is junk now as I can't afford the 5400 to replace it. The coolant kept leaking and after water pump and thermostat repairs did nothing it finally broke down. The shop says the engine is so badly warped they can't even identify where the original problem may have been.

The Sonic now runs very spotty, poor acceleration, and slow bumpy idle. Prior ball joint was replaced and the cv axil , entire engine replaced. Believe it or not, water pump replaced. These repairs, with receipts, constitute a lemon law breach. I should be entitled to a new car or compensated. Yes, the suspension issue did happen while I was driving, as well as the engine. Will upload documents soon. Oh, one last thing, very difficult removing key from ignition, been going on 4 months.
I recently purchased a 2014 chevy Sonic with 70,000 miles. Shortly after receiving the vehicle, it began dropping coolant while stationary overnight after being driven during the day. The dealer replaced the water pump. After the repair, it started to leak again. This time, the dealer's repair shop could not find the source of a leak, despite my showing evidence of a leak (photos and collected coolant). Several internet postings from different sources indicated possible problems caused by dexcool coolant specified by general motors. My own mechanic recommended replacing this coolant because of problems with the cooling system.
The water pump was leaking.
