GMC Acadia tire blowout problems

Filed Feb 19, 2025 · Engine, Fuel system · MI

I am experiencing a recurring P04FB diagnostic trouble code on my 2023 GMC Acadia, related to the crankcase pressure sensor. GM issued Bulletin No. PIP5841C, which attributes the issue to moisture buildup freezing inside the sensor. Their recommended fix is to remove the sensor, blow out any moisture, and reinstall it. However, this is not a permanent solution—the code returns within days, suggesting an inherent design flaw in the PCV system. Additionally, the replacement sensor (Part #12718935) is on national backorder, making it impossible to obtain. Many owners across multiple GM models using this engine (such as the Chevrolet Blazer and Cadillac XT4) are experiencing the same problem, yet GM has not provided a real solution. A properly designed PCV system should not allow excessive moisture to accumulate in the sensor. Instead of addressing the root cause, GM’s bulletin merely delays the issue by temporarily clearing the moisture. This approach does not prevent the problem from recurring, and it does not fix the underlying defect. If the sensor fails or provides inaccurate readings, it can affect emissions and engine performance. The fact that the replacement part is unavailable suggests GM may be restricting access to it, possibly because they know it is defective. This raises concerns that GM is quietly managing a widespread issue rather than issuing a formal recall or warranty extension. I am requesting that the federal safety agency investigate this issue, as GM's current approach does not resolve the problem. Owners should not be forced to repeatedly clear moisture from a sensor that is failing due to a design flaw. If GM has internally identified a better solution, it should be made available to affected owners instead of delaying action with ineffective temporary fixes.

The front passenger tire blew out causing me to run into the ditch. I was the only person in the vehicle but all the rear airbags deployed in the back but not in the front. The front seatbelts locked but not the back....

On november 8th, 2018 took vehicle into cappellino gmc buick, for oil change, tire rotation and inspection even tho inspection was not due until december..was told tires on these vehicles were waring unusually fast..notices were posted all over the dealers facility, told we could buy new ones for slightly less than new price because they were pro rated..this 2017 acadia was leased new, less than one year ago..we believe we should not have to pay for faulty product..at that point called dealer we had purchased from and questioned what was going on..we were told "if it passed inspection, tires should be good for another year." on 11/25/18, while pulling into driveway, the left rear drivers side tire blew out and was flat within a few seconds.. We then called dealer back again and was told to call roadside assistance then bring in asap tp dealer to get new tires. These tires are not safe. On 11/27/18 went into dealer with spare that we were told not to go over 40 miles on. They said they would split price of 4 new tires..we said ok. They then tried to put 4 new faulty tires on vehicle. We refused to purchase more of the bad tires they then gave us the option of buying a different tire that had to be ordered and sent us off with the spare still on car.. We were told it will take at least 3 to 5 days to get the other tires..we have used 20 of the miles just getting back and forth from dealer. We do not feel we should be responsible for faulty equipment on leased vehicle. These tires are not safe..there are children in this car on a daily basis. This weekend we were to be at a hockey tourn. For one of the children, rooms have been booked and he is the teams' goalie. We have no way to get there now. We were not offered a loaner or any kind of help. Had this happened on a highway of any kind there is no telling what may have happened. We hope you will check into this asap

I have a concern with all 4 of my tires on my 2016 gmc acadia. These tires were manufactured on the 10th week of 2016. I purchased my truck 4/12/2016. I have taken my truck to good year service station and gmc as instructed by gm to no avail. They are saying that this is wear an tear. All of my tires are dry rotted. My truck is only 2 years old and has 22,509 miles. The life expectancy for tire wear and tear is approximately 6 years. I do not agree with this outcome because my fianc has a cadillac escalade 2015 which he purchased in 2014 and he drives and haul's car and his tires are in better condition then mine. I have my grandbabies in my truck and now worry of a tire blow out. If I experience a blow out I will sue both good year and gmc. I don't feel safe driving in my truck and I don't feel that I should pay out of pocket when these tires are clearly defective. The batch pervious to my tire batch were recalled. Who's to say that these tires are also defective. I have attached photo for verification. I am ashamed of gmc for not taking this serious as I have. It just doesn't make sense that in just 2 tires all 4 of my tires are dry rotted! This is unacceptable to me. All I wanted was peace of mind and that they would replace these tires. Thank you for your time. I hope this doesn't happen to anyone else.
