I bought a 2015 Cruze LTZ 1.4T in Oct '16 so I'm familiar with the '15 Cruze. The '15 is basically the last year of the 1st gen Cruze and so most, if not all, of the issues with the earlier models had been resolved (coolant leaks and turbo failure w/ the 1.4T). I've put 30K miles on mine since I bought it (I'm at 75K miles now) and the only issue I had was the HVAC blower motor failed. I've been averaging 39 mpg (90/10 highway/surface streets). I started having a rough idle @ ~70K miles but a new set of plugs fixed that (easy to do even for me). The 1.8 uses a timing belt but the 1.4T uses a timing chain. First gen cars are port injected, not DI. My LTZ handles well - I recently replaced the tires with a set of 225/45-18 Nitto NT555s. Oil changes are easy, the 1.4T uses a cartridge filter and about 3.5 qts 5w30 Dexos1. The 6 spd auto has a small drain plug so I've done a couple ATF d&fs; the fill level is determined by a plug in the side of the transaxle case accessible after removing the driver's side front wheel. I don't bother with that, I just measure the amount of fluid drained and replace with Dex VI - I've gone through a 12 qt case of CAM2 Full Synthetic Dex VI with some LG red so my transaxle has fresh fluid. The cabin air filter is accessible behind the glove box.
