Im still debating if I should get a 2017 sonic RS with the 1.4 turbo. My cruze has the 1.8 naturally aspirated engine and I'm close to 100k miles on it and it's been good so far. Should I be aware of any querks and defects from the 1.4 turbo? Also, the 2017 sonics have the 1st generation 1.4 ecotec 138 HP, not the same as the new cruze with stop start technology. Do you think GM fixed the defects on the 2017 sonic 1.4 engine since they introduced it in 2011? Like the pcv valve in the valve cover and the thermostat that are not durable. Thanks!
