Fire

On 02/27/2026, a 2024 Mazda CX-50 (20700 miles) exhibited a severe burning smell following a 3-hour highway drive and a subsequent steep, 2-mile mountain climb to a restaurant in Jasper, TN. The smell was strongly observed by multiple occupants upon exiting the vehicle. On 03/02/2026, a technician at Mazda of Knoxville confirmed via video a 'flat grease ring' slung onto the undercarriage, indicative of a centrifugal lubricant leak from the driveshaft/CV assembly. The proximity of this flammable grease to the hot exhaust system during high-torque operation (mountain climbing) presents a critical fire hazard. Despite visual confirmation of the slinging grease, the dealership issued a blank service invoice, omitting the defect from the official record and returning the vehicle in an unsafe condition. This represents a documented safety defect being suppressed by the manufacturer, posing an unreasonable risk of vehicle fire or catastrophic driveline failure.

Crash 1 injured

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.

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.

The vehicle jerks while slowing down/low speed.

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 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.

upon inspection cracks were found in both rear brake rotors

The contact owns a 2024 Mazda CX-50. The contact stated that while reversing at approximately 2 MPH into a parking slot, the rear back up sensor warning was illuminated. The contact stated that the sensor was designed to alert the driver whenever the vehicle was too close to an object. The contact stated that the rear collision braking system warning was also illuminated. Additionally, the contact stated that a factory installed trailer hitch warning was also illuminated intermittently. The contact stated that the electrical failure was intermittent and occurred at various speeds. The contact stated that while depressing the brake pedal, the front brakes were making an abnormal rubbing sound. The contact stated that after releasing the brake pedal the sound stopped. The contact stated there was no warning light illuminated. The contact had taken the vehicle to a local dealer, who was unable to duplicate the failure. The contact stated that the vehicle had been taken to the same dealer several times. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was 13,522.

The vehicle hood has an angled section near the windshield that causes sunlight to beam intensely, directly into the drivers eyes when driving with the sun in front of the vehicle.

The Air-conditioning Compressor is programmed to shut off at 50% throttle position, this creates a situation that causes the inside of the vehicle to get very hot & uncomfortable during normal driving activities.

I purchased my vehicle early August 2024 at Knudson Foothills Mazda in Spokane, Washington. Within the first five hundred miles of use, I noticed that my steering wheel would not maintain center alignment. I took it into the shop explaining my issue and they were fast to acknowledge the alignment was off and that they realigned the vehicle. The steering was off center alignment within 20-40 miles so I again, contacted the dealer and told them I expect a more thorough inspection. They took a brief inspection and realigned the vehicle again. At pickup, the service advisor said "the suspension is settling, this is normal. If it happens again, don't bring it back for 5K miles." They also proceeded to tell me they could not determine the cause, so they called the Mazda Technician hotline which is where they claimed to have got their answer for me. The center alignment did not last more than 20ish miles and has gradually gotten worse. If this were "normal", they would have been able to tell me on the first visit instead of two and having to call their own tech hotline. If this were "normal", I would be able to find reputable sources online confirming this. If this were "normal", I would not have been told to endanger my life for an extended 5K miles before asking for this to be fixed again. I do not feel safe in my car. Each time I call the dealer they tell me to wait until 5K miles. I have filed a complaint with Mazda USA but have not heard anything since. I'm currently looking into attorneys to go after Mazda USA as I feel the vehicle is UNSAFE to drive and they are being NEGLIGENT on their approach with total disregard to consumer safety. Searches online indicate this is likely a result of faulty parts used when the vehicle was manufactured. I do not know what else do to besides file this complaint so a large entity can question Mazda on this SAFETY ISSUE. 1st service/realignment: 9/16/24 - approx 750 miles 2nd service/realignment: 9/25/24 approx 1251miles

While driving on a highway, a small pebble impact caused a windshield star on a Mazda vehicle. Within hours, this star developed into a full crack from the left driver A-pillar to the center of the windshield without any further impact. A few days later, two more pebble impacts on a 50-55 MPH roadway immediately caused another vertical crack from behind the windshield mirror mounting area straight downward. The windshield, a critical safety component, appears to be failing under minimal impact, potentially compromising the structural integrity of the vehicle and putting occupant safety at risk. This could lead to reduced visibility, increased risk of injury in the event of an accident, and potential for the windshield to fail completely while driving. The manufacturer (Mazda) was contacted and initially issued a warranty claim number, recommending the windshield be replaced and retained for inspection. However, after replacement, Mazda declined to inspect the glass, citing inability to examine it before replacement, despite their initial instructions. The vehicle owner reports no prior warning lamps, messages, or symptoms before the failures occurred. The owner also notes that they have extensive driving experience with multiple vehicles over 40 years and have never experienced such windshield fragility, suggesting a potential systemic issue with Mazda windshields. Similar experiences have been reported by other Mazda owners on message boards, indicating a possible widespread issue with Mazda windshield integrity. The manufacturer's reluctance to investigate this potential safety concern, despite initial assurances, raises questions about their commitment to addressing this issue. This complaint is filed to bring attention to what appears to be a safety concern regarding the integrity of Mazda windshields and their ability to withstand normal driving conditions and minor impacts without catastrophic failure.

The contact owns a 2024 Mazda CX-50. The contact stated while driving at an undisclosed speed, the steering wheel detached from the steering column. The vehicle was taken to the dealer where it was diagnosed with a stripped steering column bolt. The contact stated that the bolt was torqued back onto the steering column; however, the failure reoccurred. The vehicle was not diagnosed or repaired by an independent mechanic. The contact stated that the vehicle was purchased in January 2024. The contact stated that the failure began shortly after the vehicle was purchased. The contact stated that the vehicle had been taken to the dealer seven times due to the steering failure. The contact stated that the vehicle was scheduled to be taken to another dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 3,200.

Vehicle steering failed and caused the vehicle to go in opposite direction than intended, ended up almost hitting a streetlamp due to this. Issue had happened before and ended up on opposite side of traffic but had attributed it to loss of traction and wet weather at the time, but likely related to this. reported to dealer and they were unable to recreate or find any issue

Window shattered while idle.

Automatic transmission failure, engine malfunction, safety driver function. My car will not accelerate, or move out of 1,2,3 gear.

I rinsed off the car yesterday and a day later I noticed water spots/lines in the inside of the trunk area. I wiped them down but we have another cx 50 and when I checked that one out of curiosity it has the same leaking area.

Water leaking to right rear cargo area after rain that makes the roof trim wet, the cargo floor and spare tire compartment flooded. The water seems to flow out from seat belt opening.

Two things here. One is when using adaptive cruise control; when there is a car in front that is going slower than your speed your car will slow down. But when it goes out of the way the car will just rev up as much as it can and just catch up to speed. My Camry before this had two options of speeding up; one slower than the other so it saves the transmission. Also, my engine would randomly be at higher rpm’s than usual when at park. It would idle higher than go lower than back and forth. I’ve experienced it during cruise control when randomly my engine would be revving up and down; car being a little jerky. I’ve read online that Mazda is known for transmission issues with also their transmission sensors. Something needs to be done ASAP and fix the issue

This feature is only able to be turned off by going through 3 or 4 submenus in settings. This is extremely distracting while driving at highway speeds and poses a safety risk. This change does not persist every time you restart the car like other safety features such as lane keep assist. This leads to needing to then navigate through multiple menus while driving if you forget to turn it off every time you start your vehicle if you prefer not to use this feature.
