I purchased my car a couple of years ago and have had the check engine light on almost since then. I was told it was a leak in the emissions system but was not actually affecting the performance of the car (not needed to be an immediate fix). I've struggled to have it diagnosed since then. The transmission has been replaced when it went out, the oil pressure gauge, the thermostat, the gas cap, and a valve somewhere in the emissions system. Each time the light was off and came back on within a couple of days of normal driving.
What started several months ago though appears to be a slow coolant leak and eventual overheating (no fluid is visible under the hood or on the ground). The coolant is disappearing from the tank, but refilling the tank won't fix the issue, I have to put it directly into the radiator hose. Then the car is fine for several weeks until the same issue occurs again. I've consulted multiple mechanics and they seem stumped. Could this cause the CE light? What should I look for?
have the same problem?
