ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
As reported by others, Engine Malfunction light came on. Car running rough. Mazda dealer says corroded wiring harness and $5k to replace. They bypass the conventional repair and splice it in. Within a hour of driving after pick up, same engine malfunction light and rough running returns. This time they said I need a new transmission. Electrical issues and faulty transmission are both dangerous. With as much posted online regarding the transmission, I would hope to find a recall. $10k in repairs for a barely 4 yr old car!

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST
None of the features dependent on the Forward Sensing Camera (FSC) of my 2024 Mazda CX-30 are working. I have videos and corroborating statements to confirm that the headlights will not automatically switch from high to low beams, the lane assistance is not working properly, and the "Smart brake support with pedestrian detection" is not working. These defects have been present since I first received the vehicle. The dealer has refused to repair the issues by applying the remedies available under recall number 6824H because my VIN is not included in the recall. I emailed Mazda asking them to contact me and to call the dealer and authorize them to replace the Forward Sensing Camera. I am still awaiting reply from Mazda.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION
When driving the vehicle incorrectly thinks there is an object in front of me and engages the emergency braking function. This has happened 3 times since getting the vehicle. The vehicle also occasionally incorrectly indicates there is a vehicle next to me when I turn on my turn signal. This has happened on a clear, sunny day. The incorrect emergency breaking could put me at a collision risk if another car is behind me and/or if engaged when driving at a high speed. This could endanger my life. I took my vehicle in to the dealership to explain the issue and they “could not replicate the issue” thus it was not fixed. There were no other warning signs indicating something is wrong with the vehicle.

EXTERIOR LIGHTING
The driver side front headlight bearing has failed. Noticed after 43K miles driven. This is a known failure due to a manufacturing defect (see technical bulletin issued by Mazda) however they won't cover the repair (~$1700) beyond 36,000 miles or 36 months. This is a manufacturer known safety issue which could impair visibility while driving at night and could result in a very dangerous situation. The only "warning" is a temporary fan noise after the vehicle shuts down. As a known manufacturing defect for the manufacturing years referenced in Mazda's technical bulletin, Mazda should cover replacement of the headlamp unit (the bearing is unable to be replaced in isolation) for at least through the life of the powertrain.

AIR BAGS, SEATS
The air bag warning system shows "passenger air-bags not engaged" If involved in any accident that requires passenger air-bags to inflate, they will not. Causing serious to deadly consequences. January 28 2025 the Mazda service department had our vehicle to recalibrating the system. Checking the problem after the service still show the same problem. Another Mazda CX-30 was brought over, and the same problem existed. Also a Mazda CX-5 was tested and no problem was found. This was the second time this problem has been returned to the Mazda Dealership. This problem has existed since purchasing this vehicle.

VEHICLE SPEED CONTROL, SERVICE BRAKES, HYDRAULIC
The contact owned 2021 Mazda CX-30. The contact stated while attempting to park the vehicle in the parking garage at her workplace, the contact reversed and then straightened the steering wheel; however, after shifting to drive and attempting to drive 6-10 feet forward into the parking space, the vehicle unintendedly accelerated and crashed into a pillar before coming to a stop. The contact stated that the engine had revved up, and the vehicle made an abnormally loud sound before the vehicle unintendedly accelerated. The contact stated that the brake pedal was depressed but the vehicle failed to respond, and the vehicle failed to stop as needed. There was no warning light illuminated. The contact stated that the air bags deployed as intended; however, a warning light indicating an air bag malfunction illuminated afterwards. The contact stated that the front driver's side and knee air bags had deployed as designed. The contact sustained pain and bruises on the left side of the chest, on the upper part of the left breast, on the left leg, and on the right wrist and right arm. The vehicle automatically called 9-1-1 for Emergency Assistance, but the contact declined to receive medical assistance. The contact was able to walk away from the scene. No Police report was filed. The contact was unsure whether there was any property damage. The vehicle was towed from the scene and totaled by the Insurance Company. The contact stated that the failure had occurred once before while driving at approximately 60-65 MPH, and the vehicle unintendedly accelerated with an abnormal sound coming from the vehicle, but the contact was able to depress the brake pedal and regained control of the vehicle. The dealer and the manufacturer were not yet notified of the failure. The failure mileage was approximately 31,000.

VEHICLE SPEED CONTROL, STEERING
I am writing to report a serious safety issue with my vehicle, which resulted in a crash. While driving, I suddenly heard a loud sound, followed by an unexpected and uncontrollable shift of the steering wheel to the right. At the same time, the car unexpectedly accelerated, causing me to lose control and crash into a parked vehicle. The airbags deployed, and my car was totaled as a result of the collision. There were no obstructions on the road at the time of the incident, and the vehicle veered to the right without any prior warning. The car was purchased recently, with only approximately 3,000 miles on it and had been driven for just two months before this occurred. There were no warning signals or indications of any issues before the incident, and the car was in nearly new condition. This sudden loss of control, especially with such low mileage, strongly suggests that there is a serious mechanical issue, likely with the steering or related systems. I am requesting that Mazda thoroughly investigate this matter, as it clearly poses a significant safety risk. The vehicle has been towed to AAA Insurance for inspection, and I would appreciate your immediate attention to this claim. Please let me know the next steps in the investigation process. Thank you for your prompt attention to this critical safety concern.

UNKNOWN OR OTHER, SUSPENSION, POWER TRAIN
I purchased a brand new 2023 Mazda CX – 30 from Cooley Mazda on September 27, 2023. I was excited to upgrade from my 2011 Mazda 3, however I have had issues early on. On June 7, 2024, I brought my 2023 Mazda CX – 30 in for diagnostic testing for front end noise and a shifting issue. I went out for a drive with the Technician and was told the noise I was hearing was from the weight of the car on the suspension, I disagreed. The Technician also experienced the shifting issue I spoke of, and I was told that the car needed to learn my driving technique, again I disagreed. At this point the vehicle only had 4014 miles on it. On July 25, 2024, I brought the vehicle in for its 1st oil change and tire rotation, as well as for the same noise and shifting issues. This time they found an issue with the front driver side front wheel bearing. They did not have the part in stock, so I had to wait for a call to schedule to come back once the part came in. Again, they claimed there was no shifting issue with the vehicle. At this point the vehicle only had 5079 miles on it. On August 7, 2024, I brought the vehicle in for replacement of the front driver side front wheel bearing. On my drive home I heard the same noise I brought it in for repair for. At this point the vehicle only had 5468 miles on it. On September 4, 2024, I brought the vehicle in for a NYS Inspection and for diagnostic testing on the noise and shifting issues, again they took the car out, did not experience the issue, but put it on the lift and did some testing which determined the car needs a new rear differential. At this point the vehicle only had 6219 miles on it. The rear differential was replaced and the vehicle still has shifting issues. It hesitates, sometimes doesn't advance when the gas pedal is pressed. The vehicle also hesitates at 38-40 and 58-60 mph while just holding your foot steady on the gas pedal.

LATCHES/LOCKS/LINKAGES:HATCHBACK/LIFTGATE:LOCK
Upon opening rear hatch, loud banging/knock developed that happened on every opening. Sounded as if it were damaging the body or latch. Did online research of problem and found through Mazda owners forum Mazda TSB #09-009/23. The TSB notes the rear latch has an "internal fault in the liftgate latch and/or loose bolts." Dealers are advised to confirm the issue and replace with new latch and bolts - "This repair will be covered under Mazda's New Vehicle Limited Warranty term." My vehicle had 71,500 miles at the time of the issue, just beyond the warranty limits. I took my vehicle to the local dealership (Whitten) along with the TSB where the problem was confirmed and I was requested to approve replacement. I argued that this should be considered a recall and covered by Mazda given the language of the TSB. The dealership advised that I would need to pay for the repair and could take up the issue directly with Mazda. Therefore, I paid $512 for the latch repair because I considered the problem a potential safety issue - either it would stop opening or would not close leaving the hatch open during driving. I contacted Mazda USA requesting reimbursement for the repair given their admission that the latch was "faulty." They refused saying my vehicle was beyond the warranty period and I had approved and paid for the repair. They added that I should contact them in the future if there is a question about coverage of broken parts. Given their admission that the part installed at the factory had a fault and that this fault could result in a safety issue such as a non-closing hatch, I request that this issue become a recall, or that the warranty period be extended for this specific issue. (I would also like to be reimbursed for the cost of repairing this manufacturer's problem.)

ELECTRICAL SYSTEM
For 4-5 weeks the car often would not start. Jump the battery and it would start. Run fine 1-2 days then require another jump. At end required jump nearly every time it was to be used. Presently at Mazda dealer. They confirm the problem. They cannot find the cause. Car has been there two weeks. Waiting for assistance from manufacturer. I researched this on the internet. Visited many Mazda forums an 'do it yourself" forums. This seems to be a common problem. NO where have I read about a satisfactory solution. In fact, it sounds like there is none. Dealer's proposal so far has been to replace rear wiring harness at $7000. It sounds to me that there is a manufacturing problem. Who ever heard of a wiring harness go bad? I believe this to be a poor electronic sensor/device, or perhaps poor wiring. Either case it would be the manufacturers fault. And I believe that the manufacturer should repair it at their expense. I grew up in a garage and never heard of anything like this. The car approximately 21000 miles. All of them are easy highway miles with no abuse or offroad/dirt road use. Yesterday my wife heard about a Subaru that was doing the same thing. Maybe someone in Japan is manufacturing faulty parts. If so that is the manufacturers problem, not mine. So far the car has not stalled going down the highway but one drives it with an uneasy feeling. Stopping without warning on the roadway would be very dangerous. Also, one could get stranded in poor conditions or environment, and that makes this a safety issue. I have attached file regarding battery etc. test I performed. These test have been confirmed by the dealer.

I purchased the 2024 Mazda CX-30 from Werner Mazda in Manchester, NH on 12-16-2023. It came with defect(s) that cause interior water buildup on inside windows & roof that also caused the air bag deployers to rust & corrode & for toxic mold to develop in the car. Was obvious soon after I drove the car off the lot on [XXX]. I have taken many pictures & videos of it. Werner Mazda failed to fix the defect(s) / leaks even with video support from Regional Mazda. I filed a Demand For Arbitration with NH New DMV Arbitration Board for a vehicle buyback plus reimbursement of my out of pocket expenses which remains pending as of the date / time of this post (09-14-2024) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
