NHTSA Complaint #11607591 — 2017 BUICK CASCADA

A squealing sound was coming from the top of my engine and I had low/rough idle and it progressed to a low voltage output and check engine lights. I was able to use GM's Special Coverage Adjustment N232395320 Camshaft Cover (for the 2019 Cascada) and Special Coverage Adjustment N192291620 Camshaft Cover Replacement (for the 2016 Cascada) to CONFIRM that I had a broken/cracked PCV. The PCV vent constantly pulled vacuum (was stuck open to atmosphere) and the sound was only relieved by removing the dip stick. I took my car to the Buick Dealership for an official Diagnostic repair order and to contact GM. The dealership did a poor job of communicating the issue but eventually reported that my PCV was leaking. This is a $1800-$2000 repair(I'm outside my warranty period as I'm at 72K miles) that GM only offered $110 to the dealership as cost assistance. The offer does not cover the $170 diagnostic fee. The PCV in the Casada is integrated into the Camshaft cover and requires that then entire cover be replaced for the repair. There is NO part number difference in the Camshaft cover between model years 2016 thru 2019 Cascadas. I believe that the 2017 should be included in the same Special coverage as the 2016 and 2019 model years. This issue has been noted in several Casada forums and is also the same as NHTSA complaint IDs: 11593462, 11587414, 11574318, 11515179. Note: I would like to attach a video of the testing required to confirm the PCV issue per the Special Coverage Adjustments noted above, but it is not in your supported file submissions formats. Please provide me with an email, drop box, etc location and I will forward it.
