I have a 2015 Cruze diesel with 8000 km so I checked the clamps on the intake plumbing. One was about 3/4 of a turn loose while the rest were fine.

How Many Under-tightened Diesel Intake Clamps
On the intake of the Diesel, there are 5 hose clamps holding together the various pieces between the air filter and the entrance to the turbo. These are the type that use a flat head screw to tighten them around the tube. When I checked mine tonight while changing my air filters, I discovered that 3 of the 5 were under-tightened--two of them so loose I could turn the screws by hand without a screwdriver. As un-metered air entering the intake has been proposed as a contributing factor to the sensor failures that some of us have experienced, this is something we should all probably check, along with visually inspecting for areas that could be drawing air. I would like as many Diesel owners as possible to check their hose clamps and report in the poll above how many were under-tightened. If you had any under-tightened clamps, post the age and mileage of your vehicle below. (2 years, 46,000 miles for me.

I put all five on the survey, but it was definitely 4 and the fifth I wouldn't call loose, but it turned a half turn, others were more like 2-3 turns
A pretty high percentage of people responding to this survey have found loose hose clamp(s). Interesting miss on the factory QC. Or is it? I wonder if they just work themselves loose over time due to the diesel vibration....
I think they work themselves loose after the factory due to vibrations, I have a couple clamps I have tightened a couple times and I have 8650 miles on the car.A pretty high percentage of people responding to this survey have found loose hose clamp(s).

I have 45,000km on my car that I bought new in 2012 and the clamps have been fine. Apart from the noisy high pressure injectors there really isn't much vibration that I have noticed. Noisier than petrol, yes, but not rougher.I think they work themselves loose after the factory due to vibrations, I have a couple clamps I have tightened a couple times and I have 8650 miles on the car.
The diesel engine in the North American Diesel Cruze is definitely rougher than the gas version. Not by much, but definitely noticeable. I test drove the gas before I bought my diesel. I notice the difference in feeling mostly in the steering wheel at lower RPMs.I have 45,000km on my car that I bought new in 2012 and the clamps have been fine.

Finally got around to checking mine, none of them were lose after 73,000 miles.
My first two were loose again about a 3/4 turn.

Sounds like a job for Loctite.
They worked themselves loose?
Ditto, I rechecked mine after three months and found them "starting" to get loose again. Not horribly loose, but enough to require another 1-2 turns .
I rechecked my clamps at 16k miles and all of them were loose, I have tightened them at least 3 times in 12k miles I have owned the car in seven months of ownership. It seems like it is a activity on my car that needs checked every couple months.
That reminds me, I am about due to check mine again.

Maybe time to replace them with a better brand of them lol
I don't think it is a clamp problem, I think this engine vibrates more than a gasoline engine and the clamps are going around a rubber hose that probably gives a bit, but mostly vibration. Not really a big deal, I just check every couple months and retighted the clamps.Maybe time to replace them with a better brand of them lol
thats a strong possibility. auto zone sells these clamps that have a huge butterfly on them so you can hand tighten if needed. if plastic breaks its a simple Philips or flat under it.I don't think it is a clamp problem, I think this engine vibrates more than a gasoline engine and the clamps are going around a rubber hose that probably gives a bit, but mostly vibration.

T-bolt band clamps might work better, than the worm-gear style.
Checked mine. 1 needed about 3 turns. The rest were good.
I check mine about once a week and sure enough, they start getting loosey goosey and need a turn or half to tighten them up.
