1. What component or system failed or malfunctioned, and is it available for inspection upon request? ANSWER: Engine failure due to overheating. 2. safety & indicators: ANSWER: During evening rush hour traffic on a 3 lane highway my car went into a form of engine power saving mode while i had children in the vehicle; this was almost catastrophic form my family and the other vehicles around me. there was NO warning. there were no previous issues with my vehicle, this was unexpected. 3. technician review: this is a known issue with no warning: The technician inspected your vehicle and found a concerning issue with the engine overheating. They scanned the vehicle and found a trouble code P111A, indicating the engine coolant reached a temperature of 251.6 degrees Fahrenheit, forcing the engine into limp mode. Based on their experience, the technician believes the engine likely reached much higher temperatures, potentially causing internal damage to the engine block. After a thorough in

I am reporting a serious safety issue involving a defective suspension part (lower control arm) manufactured by Dorman and purchased from an online auto parts retailer. On October 7, 2024, I ordered a Dorman lower control arm for my vehicle and had it professionally installed on November 7, 2024 at Johnston and Magwood Wheels & Tires. On November 8, 2024, at approximately 5:40 p.m., while I was driving and made a hard brake, I suddenly lost steering control and my front left wheel collapsed. Fortunately, I was the only one in the car and managed to avoid an accident. My vehicle had to be towed to a nearby shop (Kal Tire) and was later sent back to the original shop for further inspection. On November 12, technicians confirmed that the newly installed lower control arm had failed, which caused serious damage to the suspension. I paid $1,774.10 in repairs in order to make the car safe to drive again. This is extremely dangerous — if I had been driving on a highway or with passenger

While driving on highway I get a message on my dashboard "High Engine Temperature/Engine Output may be limited" warning message. I pullover and see that the cooland is low. I wait for thee car to cool down and fill with coolant. After 5 minutes of driving, get the same message on dash. I had car towed to Martin Mazda in Delaware. Diagnosis is that I need a new EGR valve and new engine $13,000. How coincidental it has the same symptoms as described in TSB and manifests itself differently and not covered? I even had my vehicle towed to John Kennedy Mazda in Pennsylvania and diagnosis is coolant is leaking into my engine. Too much of a coincidence and I am not the only Mazda owner experiencing this. My car is part of the VIN for the Mazda Powertrain Warranty Extension Technical Service Bulletin 01-002/23 (Feb. 10, 2023). The Mazda Techs are trained to not diagnose as such not to be covered under the warranty due to the enormous economic strain it will put on Mazda corporation. Mazda gets

Vehicle jumps while driving. And sometimes stalls.

Failed water pump, blown head gasket, major coolant leak, and warped head causing the vehicle to overheat and die when coming to a stop. Vehicle died when stopped in construction on a highway and we were nearly rear-ended. Vehicle never showed check engine light and temperature gauge never showed that vehicle was overheating but significant damage was caused to the engine from “excessive temperatures.” Failure of warning signals allowed us to continue driving the car with a significant engine issue. Now the entire engine needs replaced at only 83,000 miles. Car was diagnosed by licensed independent repair shop. Additionally, front struts went out at approximately 40,000 miles making the car wobble at higher speeds. Was inspected and replaced by dealership.

Car coolant warning light came on for a short time 5 min after starting car, then would go off. During severely cold days it would come on then go off once the car was warm. On 2/25/25 the coolant warning light appeared and stayed on. The car made loud rickety noise, as it warmed up. After driving 2 miles the car coolant light turned red and began blinking. An alert appeared saying car over heating. The car was stopped and smoke came out of the car. The car leaked blue/greenish fluid. Overnight the car cooled. The next day the car continued making loud rickety noise driving to dealership. Dealership would not honor extended warranty for coolant leaks at the cylinder. The water pump cracked, with coolant leak also causing the cylinder to crack and leak oil. Dealership is suggesting total engine replacement. The car has gone through its normal servicing with no reported issues of coolant leak or depletion. The engine overheated in a span of 2 miles after being parked for 8 hours. The car

I was backing out of a parking spot while watching the backup camera when I felt a bump as if I hit something but the camera was showing I have enough space to the cars behind me. It turns out the backup camera image was frozen on the display and I had hit a car parked behind my car. Please investigate and make the manufacturer solve problems with the hardware or the software. Make sure the display shows a warning when the camera fails and the vehicle drives backwards. There may be children behind the car. Shifting into park and then into reverse again caused the camera to work correctly.

2019 CX-9 GT, 30K miles, in August found coolant leaking under the car. This was 5 months past the warranty (but only 30K miles!). After doing research online, I found this is a massively common issue with all engines from several years encompassing 2019, where the coolant leaks due to a cracked cylinder head. There is a TSB from Mazda, which requires replacement of the engine, once the crack is developed. I immediately called Mazda corporate on 8/15/2024 and opened the case with them. They said they can try to assist, but first I have to take the car to the dealer for diagnosis of the problem. Had to wait 2 weeks, then leave the car, they did a full inspection and confirmed cracked cylinder head. Dealer opened up claim with Mazda (which apparently is separate from the case I made when I called the corporate). I had to go back because Mazda warranty dept. was asking the dealer to prove the engine was overheating, which it hasn't yet, because I kept adding coolant, so the engine nev

My 2019 Mazda CX9 when you turn the steering wheel it makes a clicking noise. I brought car to a mechanic and was told there is a loose bolt in steering column. Mazda has a TSB bulletin on this issue TSB# 06-001/24 dated 01/23/2024. When I brought car to Palisades Mazda two other customers on line with me have the same issue. I looked on internet and found alot of people are having the same issue. Mazda is aware of this problem and it is a defect. Mazda is fixing this problem for cars under warranty but charging customers past warranty to replace the complete steering column to fix a loose bolt,

I have a coolant leak that I have not been able to locate. Despite replacing the radiator, the leak persists. When I contacted the dealer to inquire about estimates for changing the water pump and timing chain, they advised that it would be more cost-effective to replace the entire engine, which would require removing the existing engine at a starting cost of $5,000, with a new engine costing approximately $6,000. They suggested that if I'm already experiencing issues, it might be better to either replace the engine or consider selling the vehicle and purchasing a new one. This response implies that the dealer might be aware of a larger underlying issue and prefers not to address it directly. Experiencing a coolant leak while on the freeway can lead to serious consequences. It can cause the engine to overheat, potentially resulting in significant engine damage and a complete breakdown. This not only poses a safety risk to the driver and passengers but also to other motorists due to th

2019 Mazda CX-9 Coolant Leak. 1st warning light just discovered on June 10, 2024. Dealership quoted not under warranty and will cost $14,000 to replace engine. Mazda has an open TSB Technical Service Bulletin for this and many other Mazda's with the same engine- TSB-Coolant Leaks at Cylinder Heads, Bulletin # - 01-013/21 issued 10/15/21 (CRACKED CYLINDER HEADS). Need Mazda to stand by their product and remedy impacted owners.

Started with rough idle then got overheating msg on dashboard. After the diagnostics they found cracked cylinder head and quoted $6000 for replacement. Called Mazda USA and they denied our claim. Car is under 5yrs old & around 74k. While working on the car they noticed the turbo needed it to be rebuilt. Another $2k. There is TSB out for this and it’s a known problem, lot of others having/had same issues. Never had a car that needed an engine replacement even before car is paid off.

In June of 2022, Mazda issued a TSB for an engine flaw that cause coolant to leak in to the engine and significant overheating occurred. This overheating causes the head to warp. The TSB states that the only repair for this is a newer model engine. This happened to my Mazda CX9 and quite a few more. There are class action suits currently ongoing. Mazda never made its owners aware of the TSB. The car can shut down on the highway which is dangerous to all.
