2017 1.0L Ecoboost Issues. I own a 2017 Focus 1.0L SE Ecoboost. The auto start/stop has stopped working no matter if you have it on or off, and now it's also slow getting up to speed but once your at speed it's ok. Are these related or what could be the problem. No engine light or faults pop up.
According to Ford, the two problems are unrelated issues. The coolant hose on the 1.0 Ecoboost engines of cars built between October 2011 and October 2013 can potentially fail at high temperatures

If your fuel injected, you have a pesky computer and oxygen sensors. They have what is called "upstream" and "downstream" oxygen sensors.
Ford Focus 1.0 EcoBoost engine failure - Graham Bartholomew As an update to this topic I would add that in the last six months no fewer than 26 cars fitted with the 1.0L Ecoboost engine have suffered engine failure almost all related to cooling problems but not all related to the degas hose failing.

While this is a possibility, the most common problem is a faulty catalytic converter. Do not overlook other codes that are paired along with P0420. Codes like P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, and P0308 are misfire codes, and these codes require misfire diagnosis.
