I think that is a big problem honestly. When do we stop considering common problems as acceptable problems? These issues started in 2011 on the Cruze and should have been engineer corrected LONG ago. These owners of 2015 and later models should in no way be seeing any of these issues.
But both seat heaters, AC, rear defrost and shifter button too? The car spent 99% of it's life on a 25 mile round trip work commute for my wife. Parked in a shady parking deck at work and a shady garage at home. The roads driven on are smooth and we'll maintained too.
Again. The car really has had more real failures than pretty much everything else I've owned combined. I'm not mad. Just disappointed. I had hopes that GM of old was gone and forgotten. Seems they were just reincarnated in a different form.
I understand the frustration and disappointment. The truth is, many of the parts are sourced from the same vendors across different brands including foreign transplant brands. Not saying anything should be acceptable. . . . just that it is common and in the case of the PCV valve and intake manifold it has become a maintenance item. I know and realize it was also a problem with the Cruze. Same engine after all.
If you haven't kept up with the forum references, here is a thread with links that can help proactively with PCV maintenance.
PSA: 1.4L PCV System Maintenance IS Required
These are cheap, low cost cars and ALL car makers have one kind of chronic issue or another. Do some searches on Honda Fit, Toyota Yaris or Nissan CVT Continuous Variable Transmissions. I've been associated with the automobile industry for+30 years and keeping cost down is primary for all car makers whether we agree with it or not. It is not just GM.
Rather than be a victim we can look at the issues and see what there is we can do to proactively deal with it. Cleaning the PCV valves (yes 2 of them) or replacing the intake about every 50K miles is not that expensive. Cleaning the PCV valve every year with some CRC MAF Sensor cleaner would lengthen that greatly.
I did not like that and is one reason I bought the 1.8L in the Sonic. It's just that more parts on cars these days fall into the routine maintenance or replace category. The good news is that for a few hundred dollars or 3 to 6 years the cars can be kept running well.
And the good news also is these parts are user serviceable, unlike some things on Toyota, Honda, Mazda and others.
I looked at these things before even buying a Sonic. It behooves all of use to do some diligent research before buying any vehicle.
I did before buying our Sonic in 2017 and found that the often mentioned thermostat, water outlet, water pump, and PCV not a big deal. In the 1.8L there is also the timing belt, but many go even past the 90,000 mile point of recommended replacement. I wouldn't .
I agree, the heated set elements is another bother, but those often went out with use and age in vehicles of past years as well. Also, those can be user replaced if so inclined. The shifter button spring also is a nuisance item, but cheap repair.
I think I can say that if you bought some other small economy car you would be dealing with much more costly ans serious repairs and maintenance from engine issues to transmissions and more.
Our daughter has a 2014 Sonic LT 1.8L with about 80,000 miles on it. I replaced the Evap Purge solenoid valve on it $22 Amazon, changed the auto trans fluid, and it will need brakes and the timing belt. Maintenance items.
She has had a couple warranty repairs. . the thermostat was still covered no charge. And I think sway bar links . . no charge.
From the way she drives her car, frankly I am amazed at the few repairs she has had.
I do not know how many newer cars you currently have, but you will likely find that any car made starting in 2010 or so, will have more repairs than what we are used to going back before that. Reasons for this are many. One is, IMO, the focus is to supply more "tech" in cars which is not necessarily cheap, so cost are cut elsewhere. And most newer cars have GDI engines and more complex engine tech is coming soon. These cars are likely to be subject to costly failures. Why? Because this is a time auto makers are forced to obtain even more stringent MPG figures than 10 or 20 years ago. So the growing pains of putting newly developed engine tech into practice will show up. That technology stresses cars in ways not seen before.
One place I see people taking short cuts is simple oil changes. I do not and would not use the oil % display as a reliable means for telling me when the oil should be changed. Many wait till very low or 0% before changing it. Some have even gone 10,000 miles and never check the oil level.
Synthetic or not, I will change my oil every 4K to 5K miles or less if it is during winter months with cold starts and short trips.
Whether you see and agree with these things or not. . . it is the reality of the automotive world today. I don't like it either, but I try and choose carefully what I buy now more than ever and realize cars have more maintenance/repair items now that in past years. It's not just GM. I have worse experiences from Toyota, Nissan and Chrysler/Dodge products.
