2019 MAZDA CX-5 Complaints

Oftentimes when driving at speeds of approximately 80mph or more, a loud whining/whistling noise appears. It appears to be coming from the area of driver side front door, passenger side front door, both front doors simultaneously. The issue has an earlier onset in the presence of crosswind, or headwind. I was able to record several videos where the noise can be heard very clearly. Some of these videos have been posted online: https://vimeo.com/547826873 https://vimeo.com/manage/videos/580602909 and the links have been shared both with my local Mazda dealership (Oak Tree Mazda by DGDG in San Jose, CA: 4250 Stevens Creek Blvd, San Jose, CA 95129) as well as with Mazda of North America. However, my complaints have been ignored as the dealership keeps stating that they are "unable to duplicate problem". There are several threads on two Mazda owners forums that describe this very issue with Mazda CX-5 in USA, Canada, as well as in Europe. This video from an owner in Germany shows the very same issue: https://www.youtube.com/watch?v=zykyoCIsItc&t=204s https://www.mazdas247.com/forum/index.php?threads/2019-cx-5-signature-whistling-noise-on-highway-or-high-speeds.123868506/page-2#post-6727077 https://www.mazdaworld.org/threads/cx-5-2018-version-high-pitched-squeal-whistle-like-noise.337073/#post-754625 According to one of the forum members, a Technical Service Bulletin (TSB) R084/20 to address this issue has been issued by Mazda in Europe and Russian. The root cause has to do with door trim seals. Under the "CASUE", this TSB reads, "When driving under following conditions, a negative pressure generated on the doors pulls them outside. The counterforce exerted by the weatherstrips mounted on the doors is lower than the sucking force, resulting in weatherstrip vibration. -The vehicle is exposed to a side wind while driving at a speed higher than 160km/h -The vehicle is exposed to a strong side wind while driving at a speed higher than 120km/h."

The contact owns a 2019 Mazda CX-5. The contact stated that on five separate occasions, intermittently there was an abnormal grinding noise detected underneath the hood. The contact stated that while driving 65 mph, the vehicle inadvertently decelerated to 20 mph. Additionally, while accelerating the vehicle slowed down without warning. The vehicle was taken to an independent mechanic where no codes had been detected. The vehicle was towed to the local dealer where they were unable to duplicate the failure. The vehicle was not diagnosed nor repaired. Additionally, the vehicle was towed to Sport Mazda North (400 N US Hwy 17 92, Longwood, FL 32750, (407) 339-4777) where they were unable to duplicate the failure. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was approximately 17,000.

When the system think there might be a collision and initiates a hard braking even when there might be enough space in front of you. Multiple times, the car behind me had to do a hard break as well not to hit me from behind. This also happens when switching lanes. As you are in the middle of switching, if sometimes thinks you are getting to close to the car in the original lane and it starts a hard break. Since I’m in between lanes, it causes the car on the other lane to do a hard break also, almost causing a chain accident. A google search revealed multiple people complaining of that. The system is too aggressive even at it’s lowest setting. Mazda informed me I can only turn it off one drive cycle at a time. This system has almost caused more accidents than it protected me from them.

Driving on highway, cruise control ser to 82, no cars in front. The car suddenly jolted twice, engine light and battery light comes, lost of power. Pulled over to shoulder in the middle of nowhere in Nevada. Tried to start the car, engine won't turn on, starter just kept cycling. Veh temp was just below 210 with a 1/4 tank of gas. Called dealership and service person asked is to use key to turn on car, no change and provided no other solution other than to take to dealership with the closest one being over 300 miles away. We decided to unhook and rebook the positive side of battery. Car restarted and currently driving it home as I write this complaint. 600 miles overdue for maintenance (by date due on July 26, 2021) and was scheduled upon return from trip which at the time should be approx 1000 miles over due.

UNDER SHIELD FELL OFF AND NEEDED TO BE REPLACED TWICE.TIRE PRESSURE WAS GOING OFF AND BROUGHT IT IN TWICE FOR THEM TO SAY THEY CANT FIND WHERE THE SLOW LEAK IS OR WHY SO THEY WOULDN'T FIX IT EVEN THOUGH I HAVE THE MAZDA INSURANCE FOR TIRES.

I HEARD A VERY LOUD BANG, SOUNDING LIKE A GUNSHOT THAT WENT OFF, WHEN THE SUNROOF ABOVE MY HEAD VIOLENTLY SHATTERED WHILE I DRIVING TO WORK. I ALMOST LOST CONTROL OF THE CAR AND GOT COVERED WITH PIECES OF GLASS. THE GLASS SCRATCHED ME ON THE FACE, CLOSE TO MY EYE. I AM IN SHOCK AND I AM STILL FINDING SMALL PIECES OF GLASS ALL OVER MY BODY EVEN AFTER TAKING A SHOWER.

REAR PASSENGER SEAT REST BEHIND DRIVER SEAT IS RATTLING AND DOES NOT LOCK TIGHT. THIS HAPPENS WHEN PASSENGER IS SEATED.

VEHICLE HAVING SIGNIFICANT DROP IN POWER OUTPUT IN 1ST AND 2ND GEAR WHEN AMBIENT TEMPERATURES BELOW FREEZING. ISSUE RESOLVES WHEN FINALLY SHIFTING TO 3RD GEAR, BUT LACK OF PREDICTABLE RESPONSE WHEN MERGING IS UNSETTLING.
