Hello everyone. I knew there were many people having this problem despite the dealers and Mazda saying they never heard of this before. Evidently it has been happening for years. Thanks to those that sent me measurements, but what I needed was measurements of your actual trunk mat and then of the cargo area with the trunk mat removed. Here is what I accomplished Saturday. We went to 2 dealers in my area and compared 6 CX-30s. They ALL had the same fabric bunching problem. ALL of them. And, to make things more interesting, we also checked a CX-50 which has a MUCH better cargo floor that is heavily reinforced versus just our cardboard cutout. Well the CX-50 had the exact same fabric bunching problem. As soon as we opened the tailgate it was right there and almost all the way across. When we put the rear seat down, the fabric just laid there in an ugly clumped up pile. We confirmed the CX-50 also used the same poorly designed fabric adhering system. The sad and funny part is while we were doing it, the dealership personnel which included Sales and Service Management who saw it all said they never saw or heard of this before. Nobody had any idea how to resolve it and they would all have to call Mazda about it. They all also said they had zero complaints about it. So we all guessed that people simply just jammed the fabric back down and chalked it up. One Service Advisor notes that all the CX-30s VINs started with a 3 which meant manufactured in Mexico versus Japan and maybe that was the problem if they installed all the rear seats too far back. FYI, they all confirmed this was a factory error that also was missed by the Factory Final QC, US port final QC, and the dealership PDI (pre-delivery inspection). All of the Service personnel agreed the fabric at the bottom of the seats needed to be secured better and that the velcros that was used was too weak and in the wrong location (too high). Just to confirm, all 6 of these CX-30s had the same cargo mat measurement of 31 and 7/8 inches long. The empty cargo areas all measured 31 and 1/2 inches long for a potential gap difference of 3/8 inch. Based on that we tried simply lifting the rear of the cargo mat and moving the mat back approx 3/8 inch which created an approx 3/8 inch gap. That did allow the seats to be raised and lowered with no bunching. The fabric does still make some contact with the black styrofoam but since it is soft and pliable it did not jam the fabric. I did also install additional velcro strips and double-side tape near the lower area of the seat fabric and that helped to keep the fabric where it should be but only with the cargo mat not installed. I provided all this info to Mazda including pictures of the CX-30 and CX-50 bunched up fabric and photos showing how the sharp edge of the cargo mat leaves clear indentations on the fabric because of how tight it is. Since there is no reinforcement under the cargo mat up near where it makes contact with the lower seat I am concerned that if we cut the cargo mat down to create the gap that the front edge of the mat will potentially get bent down if something is placed there with the seats up or down. Mazda said they never heard of this issue and had no other complaints in their system. Please also call therm at 1800-222-5500 to complain about this. I told them that since we had proof of 6 additional CX-30 and the CX-50 (which was a 100% trial score) that this was not a one-off problem. It is a manufacturing design flaw that was also missed by all the final QC checks and the dealership PDI procedure. It is a problem that is easily and seen and obvious. If Mazda and dealership personnel are simply shoving the fabric back down hoping the customers don't notice that is shameful. Especially since customers with CX-30 of multiple years are having this same problem. So I gave Mazda all my measurements and photos and asked them to please let me know what are the actual factory measurement so we can all confirm if the cargo mats are cut too long or if the rear seats are installed to far back. I don't want t be subjected to any trial-and-error attempts to remedy this. They have my measurements of 7 CX-30s and they know what are the actual factory measurements. That should be enough. FYI, my qualifications include being a tester for Audi where we would drive and test all pending Audi models searching for defects, design errors, etc... but more importantly also providing ideas to the factory how to remedy the defects and design problems. I let Mazda know this because they have similar field testers who I am guessing missed this problem (or maybe didn't miss it). Perhaps we will confirm this is a Mexico manufacturing problem, but that means it was also missed by US Port final QC, and multiple dealers PDI. So fr now, we have to move our cargo floor slightly before raising our rear seats. And Mazda tries to brag about their quality? I have als passed this along to Car and Driver magazine and Edmunds who said the CX-30 was their #1 choice by far in this segment. Shining bright lights on this problem will hopefully get it fixed faster.
