When driving at highway speeds, when there are strong crosswinds, as there are prone to be in my area, depending on which way the wind is coming from both doors will make a screeching/howling noise. This noise is very loud and extremely distracting. When it first happens it is very jarring, and depending on the wind conditions can go on for miles, making it very hard to hear anything else. I have taken the car to two dealers who refuse to fix it because they state they cannot reproduce it but it is not something that can be reproduced without specific conditions, but they are aware it exists as they have a TSB indicating how to fix it.

The rear camera and warning system has failed numerous times. On one occasion I hit a vehicle because of the failure. Also, the windshield has a leak that sometimes is like a waterfall causing serious visibility problems.

THE RED PAINT IS CHIPPING PRETTY BAD. THIS CAR IS ONLY ABOUT 1 YEAR OLD. THE CHIPPING IS MOSTLY ON THE HOOD OF THE CAR.

THE AUTO LIFT GATE OPENS ON ITS OWN. WE JUST BOUGHT THIS IN JULY AND HAVE FOUND IT OPENED ON AT LEAST 4 OCCASIONS. ONCE OUTSIDE AND THE OTHER TIMES IN THE GARAGE. IT OPENED IN THE GARAGE AND DID NOT REALIZE IT WHEN I PUSHED THE GARAGE DOOR OPENER. IT WAS ABUTTED AGAINST THE DOOR AND CAUSED DAMAGE TO THE LIFT GATE. IT IS NOT THE FOB, BECAUSE WE TRIED IT INSIDE WITH THE DOOR SHUT AND THE LIFT GATE DOES NOT OPEN.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Mazda Cx-50 verdict →
