Hey guys, my first time on here. Bought my CX30 in Aug 2021 and recently took for diagnostics as during heavy rain, the rear floor behind the passenger seat has gotten soaked twice. Car was not in use and parked on a flat surface. The second time I put a towel down overnight and it was absolutely soaked by the morning. Mazda ‘tested’ the seals with a hose and came back inconclusive, unable to find the leak. They tried to charge me for the testing but I refused and managed to get out of it, but they found ‘evidence of water having been present’ under the carpet on that side all the way up to the passenger footwells. Car has less than 6K on the odometer so very nervous about finding the problem getting it rectified. Any ideas?
