This sounds like an early run manufacturing issue. Later engines haven't been having this issue.Just wondering if GM has a fix that is all. We here people having the issue and getting there vehicle fixed, but no real reason why it happening.
17's have had it happen too. Not sure whether there's any correlation between Mexico/US assy for the 17 model year.This sounds like an early run manufacturing issue. Later engines haven't been having this issue.
GM's TSB for piston replacement specifically calls out looking for leaks or conditions that may cause it to run lean. I haven't yet had an O2 sensor issue on my 16.5, but I could see that as doing it.Thats interesting because we do have people on here with 2016.5 with no issues and have close to 40000 miles. I am at 14000 and my car runs great. Just had the O2 replaced for the P015B code that seems to be popping up. Was the O2 sensor and this code causing this issue of running lean and burning up pistons?
12.5 or so.Do you have a copy of the TSB? Also how many miles do you have on your 2016.5? Mine runs great, it has had a little rough idle a few times but nothing big.
How many miles on the car?We had a 17 Cruze towed into the shop Thursday with damaged pistons. Teardown and repair will happen this coming week.
Wow, not much milage. Good luck on the repairs!I can't remember, I think it was low, like 20-30K miles. If I remember, I'll look on Monday.
may I ask what octane grade of gas used and when vehicle was made (early or late) just curious!We had a 17 Cruze towed into the shop Thursday with damaged pistons. Teardown and repair will happen this coming week.
