Won't start

Chevrolet Cruze 2013 Manual, 90000 miles
I hop into the car to leave for work but the engine won't start. No sparks so I know it's not the battery. The engine light is on.

I found that the cable connection between the fuse box and the battery was loose.

The car doesn't start at cold weather

Chevrolet Cruze 2013 Hatchback 80000 miles
Hi! I have a Chevrolet Cruze J305 Diesel-2013. The car doesn't start at cold weather. I went to a service and they checked the spark plugs and it seem to be fine. They changed the car relay, the temperature sensor, the battery, water pump, the diesel filtre. The problem is still there. Is there anyone who had this problem? What can I do? Thanks.

If it's a diesel and they charged you to change the spark plugs then you need to find another shop to go to and I would also get a lawyer. Diesels do not have spark plugs. They have glow plugs. If your glow plugs are bad then that's why your car will not start in cold weather. Glow plugs preheat the cylinders so the combustion process is easier. It will still run with bad glow plugs. It will only be harder to start if bad.

Persistent P0420 Code

Chevrolet Cruze 2015 LT, Turbo 111000 miles
My check engine light keeps coming back on with the code P0420 on my 2015 Chevy Cruze LT. I've replaced the front catalytic converter, both O2 sensors (one is aftermarket and one is GM made based on advice from a Chevy mechanic), replaced all the spark plugs, replaced coolant hoses, the coolant container, did a smoke test and found no leaks... I'm out of ideas on how to fix this code. The car drives just fine unless I ride it hard (fast accelerations and/or high speeds for long distances), then it will stutter and the check engine light will flash. If I back off and give it a few moments, the… Read complete

Have you fixed it yet I have the same problem

No, still haven't fixed it. I asked on Reddit and some people think the fact that I replaced the original catalytic converter with an aftermarket one could be the issue. Did you replace yours with a GM cat or aftermarket cat?

I got a 2013 Chevy Cruze mine stuttered too at one point I would check your coil pack because if one of those things goes out I will make your car misfire and stutter that’s what my issue was. As for the p0420 code I have the same thing I’ve replaced my catalytic converter and my o2 sensors but this whole time the problem has just been a small exhaust leak

Rough idle, sluggish acceleration.

Chevrolet Cruze 2016 hatchback, 1.4l petrol, z series, automatic 97350 miles
Rough idle at idle, but fine when driving; acceleration feels sluggish; suction when removing the dipstick; slight fuel smell. My theory is either PCV, spark plugs, or coil packs. I've ordered an OBD scanner, but want an opinion.
There's also no check engine light yet

Vibration when in park or and stop light

Chevrolet Cruze 2014 1.4 Turbo LT 2258458 miles
Vehicle will vibrate and rock back and fourth when in park or at stop light, it's especially bad when damp/wet conditions.
Ive replaced the starter I thought that was issue (it was corroded). Currently working on coil pack and spark plugs... could it have to do with anything else? Maybe fuel pump? I have one i have yet to get replaced. Thought it was battery had that replaced, checked the mount thats still good. But of a leak under the hood cant locate where coming from could do that have to do with it? Electrical??
