Massive coolant leak. Been happening on and off since I bought the car in nov2019. Taken to several shops and have had replacement done and it goes right back to leaking. This time the shop believes it's leaking into the engine itself.

I've had my encore for almost 2 years. It is a 2015 and just under 50000 miles. For the last month its been saying awd off. This is as soon as the car starts. It also dibgs and comes up again every 10 minutes while driving. I've.consulted the manual and it says overheating and to turn back on. This does nothing. It's been icy here and I'm starting to feel unsafe. I don't know what.to do. I cant shell out hundreds to have it looked at.and have someone not be able to fix it.

There is a constant coolant leak appears to be coming from the turbo area. Coolant smell is constant as the coolant is being burned off by exhaust manifold. Loss of cooland can lead to overheating and engine failure.

Driving on freeway, approx 74 MPH in a 75 zone. About 1.5 hours in to a 2.5 hour trip. All systems were functioning and no warning lights were on. Car suddenly lost power on gas pedal , power steering light came on, check engine light came on , all gauges are functioning erratically and then all gauges stopped or went to zero. Light indictating the transmission gear kept changing. But the cars tranny didn't shift or change just the light for the gear indicator wasflashing. Car slowed to approx. 40 MPH, with the RPM's racing to approx. 4500/6000. Engine was still running and not over heating or any other lights except check engine and power steering light. Stopped car on shoulder to take inventory of situation, car running and idile RPM's seemed normal chk. Engine and power steering light still on, proceeded to drive again . No leaks or overheating . All gauges came back up/ on. Proceed to drive ... Car had no acceleration , very little , like the car was still in a higher gear . Speed up very slowly until it reached approx 55-60 MPH. But the RPM's were at 5500/6000 , felt like the tranny needed to shift but wouldn't. Slowed down to approx. 35-40 .. To get RPM's in line or more in line. Drove home last hour on side roads and frontage roads with flashers on. Can't drive that slow on a freeway. All of car functional were normals , AC , radio ,windows , lights . Just the power steering and check engine light stayed on with no acceleration power or power steering ....called dealer monday morning for a tow into the shop .
