2024 MAZDA CX-50

ELECTRICAL SYSTEM

The vehicle had the original OEM battery fail at 15 months. It dropped to 7v under light load. It's a bad battery. Upon being jump started, the power steering went in and out while driving and the dashboard blinked on and off...throwing a lot of errors that are unrelated to the battery problem. The failure state of the vehicle with a bad battery is unlike any vehicle I have ever seen and it is extremely dangerous. Furthermore, Mazda roadside assistance does not know about this issue and only offers jumpstarts, putting customers into danger by suggesting that the vehicle is safe to drive with a battery that is not stable.

VISIBILITY/WIPER

This update pertains to the original complaint (11613144) regarding windshield integrity issues on a 2024 Mazda CX-50. A new crack has occurred on [XXX], with cracks consistently radiating from the driver's A-pillar side. This pattern suggests stress fractures rather than impact damage, as initially assumed. The vehicle was taken to a Mazda dealer in Seekonk, MA, but the Mazda Service Manager denied warranty coverage without an in-person inspection, relying solely on photos taken by a trainee service advisor. These images clearly show a recurring pattern of cracks in the same area, which is concerning. Research into Mazda forums reveals numerous reports from other owners experiencing similar windshield failures, including unexpected cracking, chipping, waviness, visibility issues, and delamination. Many report quick denials of warranty assistance, similar to this case. The frequency and similarity of these reports suggest a potentially systemic issue that may be more widespread than the recent hitch recall. The manufacturer's reluctance to investigate raises serious concerns about windshield safety. After three cracks and two replacements, Mazda has not physically inspected the issue. This situation warrants a thorough investigation by NHTSA, including major glass providers and installers, to ensure occupant safety and address potential systemic failures. The lack of proper reporting and inspection by Mazda underscores the need for NHTSA intervention to protect consumers and ensure that safety standards are met. Furthermore, the consistent denial of warranty claims without adequate inspection may indicate a broader problem in how these issues are handled, potentially affecting many more vehicles than reported. This pattern of failures and lack of action by Mazda necessitates a comprehensive review to safeguard public safety.

FORWARD COLLISION AVOIDANCE: WARNINGS

Collision Prevention System is dangerous. I was nearly rear ended going 75 mph on the PA Turnpike. I was passing a truck that was in the right hand lane when all of a sudden the brakes automatically engaged hard and I nearly was rear ended by another vehicle that was right behind me. It braked so hard it made the tires squeal. I contacted two dealerships and told them what happened and both told me there haven't been any problems with the system that they were aware of and maybe a software update would help. Neither dealership checked if a update in fact was available. I turned the system off and will never turn it back on because it is so dangerous!

FUEL/PROPULSION SYSTEM

Fuel issues P0460 fuel level sensor circuit. Engine malfunction light comes on with fuel sensor issue. The car is full of fuel or not even close to be empty but the sensor reads off triggering a chain of event. Killing car mid of the highway when it got enough fuel. Average full tank ranges 280mi, this instance it only drove 202mi and the sensor reads 14mi to go with quarter Guage left in the tank. Then the needles drops by a notch. I can't upload the video but attached at the screenshot. Contacted dealer and they won't diagnos till 90days out. This is safety hazard and the car comes to halt in the mid of the drive. Where it's highway, parking lot, or anywhere; as if it's out of gas but the tank still good. Wait for few minutes and restart the car the garage read normal. The dealer doesnt want to listen or even consider this as safety issue. Multiple dealer reject to even make an appointment and request that I go to the dealer I purchased the car from.
