MAZDA Complaints

While connected to a level 2 charger, overheating caused both the charger and charging port of the vehicle to melt together such that it was very difficult to disconnect, and both were then unusable – needing replacement. (photos attached) We feel that there should be some safeguard in the vehicle to prevent this situation as it is a fire hazard. There were no warning lights, sounds, nor signals from the vehicle to warn of the problem. We were present when this occurred, so we could disconnect before a potential fire may have occurred. When we called for service, we had to wait two weeks for an appointment, and then were told that the car was not safe to drive until repaired. This was not considered a warranty item even though the car had fewer than 2800 miles and only owned by us for fewer than 7 months. We were charged $5000 for the charging port and cable assembly and $800 labor. (Copies of service receipts attached.) We contacted Mazda regarding our concern and were given Case #00182286. We received a reply by phone telling us that Mazda bears no responsibility for this (they feel ii was the fault of the charger) and that it is an insurance matter. In fact, auto insurance does NOT cover this. Our concern is that it very well may be a safety issue as people usually charge in their garages or near other cars and buildings in public. In either situation, a fire could be a serious hazard for many people.

I started smelling coolant after exiting the vehicle from a drive. Coolant level was very low. Adding coolant did not last long. I could not see where the leak was. The dealership evaluated and determined I had a cracked cylinder head and the car is leaking coolant near the rear of the engine. This could cause the engine to seize should coolant get into the engine. The dealer (New Rochelle Mazda) explains the cylinder head needs replacing. The dealer also observed bad rear sway bar links. One was detached. The car is serviced at the same dealership every 5k miles. The car has approximately 85k miles. The cylinder head has been repaired by the dealer under the extended warranty. Safety risk was moderate as the car could have stalled on the highway. The component was inspected by the warranty company and dealer only. The only warning lamps that showed up once were both brake indicator lights came on and the climate control would not warm the car.

My 2018 Mazda CX-5 had a rubber burning smell and smoke leaked into the cabin. I noticed the next morning, oil leaked onto my driveway. I brought the car to the dealership and they mentioned it was a cracked cylinder head. My car has approximately 49,200 miles on it and it about 5.5 years old. It is under the mileage limit for powertrain warranty but slightly over on the age limit for powertrain warranty. Mazda informed me that they would cover roughly 37% of the repair costs that the dealership quoted me. I've read online on various Mazda forums that many owners are dealing with the same issue and Mazda admitted that a batch of heads have a manufacturing defect. Owners on this forum mentioned Mazda covered 100% of the repair costs for cars that were out of warranty due to this being a known manufacturing issue. I think the proposed coverage that Mazda provided me is insufficient.

The contact owns a 2006 Mazda Mazda6. The contact stated that while the vehicle was at the local service center for maintenance, it was discovered that rust and corrosion was present on the front passenger’s side lower control arm. The vehicle was not yet repaired. The local dealer was notified of the failure and informed that the model year was not included in a Manufacturer's recall for the same failure. The manufacturer was not contacted. The failure mileage was 142,000.

At 3200 miles the vehicle had a major powertrain malfunction causing the vehicle to throw multiple error codes - Hybrid System Malfunction; Charging System Malfunction; Electrical Leakage Detected. Was instructed to pull over to a safe area immediately. Was unclear how long car would continue to be drivable. Once car stopped it became completely immobile. Repeated restart attempts would not let vehicle start ICE engine or shift into gear. Had to be towed via dollies to nearest dealer for diagnosis and repair. Dealer found a failed PTC heater unit as source of problem and replaced it (Mazda part- KMV6-61-FHX). Vehicle is once again drivable, but the dealer has no idea what would cause the unit to fail and how to avoid future problems. Dealer has heard about this with many vehicles and repaired several similarly. We are fortunate to have found a safe place to pull off the road before powertrain shutdown, but if not we would have been stuck on the road with no ability to move the vehicle and occupants to safety. I hope NHTSA can investigate whether a recall of that part or the software that controls it is needed. NHTSA should also look into the failure mode of the vehicle to see if a different approach is safer and more appropriate.

1st instance 12/06/2023- The battery was drained and it won't start so they changed the battery. Dashboard light says engine malfunction have the vehicle inspected. 2nd instance 02/10/2024- same dashboard light Engine malfunction and Hybrid malfunction. This time they said that DTC was P0E10. They also noticed low battery charge warning. Battery was charged with DCA8000 charger and they said that notif went away. 3rd instance-02/23/2024 same dashboard light. This time they had DTC's of 5. P0E10, P1739:12, P1B05:16, P1739:00 and P1B05:00. to think this is a brand new card purchased last october 2023 with less than 3000 miles.

My sunroof just suddenly explode while driving at the highway with my kids, we almost got into a car accident. It sounded like a gunshot. Never get crack or hit by stone before we travel.

My 2011 Mazda 6 rear suspension broke while my wife was driving our car on the highway. It could have killed my wife and son. The frame is rusted so bad that the lower control arm broke away from the frame, the rear wheel is barely hanging on it by one bolt on the front control arm. It is very much a safety issue and Mazda needs to take charge of the problem before someone dies in their vehicle. Our car has 106215 miles on it and we still owe alot of money on this thing.

The door locks and some of the settings like the lane departure & the blind spot monitoring all of a sudden do not work consisently. The door locks do not stay locked and lopen whilde driving or at night agter they have been locked. The setting are set for them tpo lock on their own-not consistent.

Started hearing a rattle in the mid console of the car that gradually got worse. When i checked under the car, there was a bolt missing and one hanging that was suppose to be holding the propeller shaft. When i took it to the dealer, they tried to lie and say that they were only loose which is what you will see on the paperwork but when i confronted them that i saw one was missing and the other bent, they said yes, they don’t know what happened but they fixed it.
