My Aveo’s been reasonably maintained (oil, coolant, thermostar, timing belt etc.) The last year or so cracked 3 coolant reservoir tanks, boiling over and now missing a little at highway speeds. 3rd owner with 109, 100 miles. Runs very well otherwise. Thanks.

Try replacing the pressure cap on the coolant tank.
