It’s now in the shop being torn down for further inspection but it looks to be a cracked cylinder head leak .

Engine
Filed Jul 10, 2026KY

The engine cylinder head developed an internal coolant leak, allowing coolant to enter the combustion chamber. This caused engine overheating and smoke coming from the tailpipe while driving. A dealer performed a coolant pressure test confirming coolant leaking into the combustion chamber, and wet/dry compression testing on all 4 cylinders showed low and inconsistent readings consistent with cylinder head coolant intrusion (Cylinder 1: 105/125 psi, Cylinder 2: 115/125 psi, Cylinder 3: 110/175 psi, Cylinder 4: 160/190 psi). Overheating creates a risk of sudden loss of power and potential engine failure while driving, including on the highway. The problem has been confirmed and diagnosed by an authorized dealer service center, and the manufacturer's technical hotline department reviewed the diagnostic findings directly. Warning symptoms (overheating codes and visible tailpipe smoke) first appeared at the time the vehicle was brought in for diagnosis. The manufacturer has an active technical service bulletin addressing cylinder head coolant leaks on this engine and model, along with a related warranty extension program, but has denied coverage for this repair on the basis that the leak is internal rather than external.

My 2019 Mazda CX-9 (VIN [XXX]) suffered catastrophic cylinder head failure on the SKYACTIV-G 2.5T engine at approximately 124,000 miles. The failure is consistent with Mazda TSB 01-013/21 (and successors 01-007/22, 01-010/24), in which Mazda acknowledged that cylinder heads on this engine can crack at the stud bolt hole and exhaust manifold flange due to manifold deformation and residual production stress. The first warning came in mid-May 2026, when the engine temperature warning illuminated during normal driving. An independent mechanic replaced the thermostat. The warning returned within a week, and the thermostat was replaced a second time with a higher-quality part. Four to five days later, the warning returned alongside more severe symptoms: the vehicle began jerking while in motion, a strong coolant-burning smell developed, and smoke was visible from the exhaust pipe upon shutdown. The vehicle became undriveable, had to be left at the failure location, and was towed. Safety risk: The jerking compromised vehicle control in traffic. Upon shutdown, smoke and burning coolant odor created fire and fume-exposure risks. Had this failure occurred at highway speeds or in heavy traffic, the sudden loss of engine power and erratic behavior could have caused a serious collision. Family members were in the vehicle during several escalating events. Confirmation: The vehicle was towed to an authorized Mazda dealership, where Mazda-certified technicians confirmed in writing that it is

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 inspection, they found no external coolant leaks, but upon using a digital borescope, they discovered evidence of coolant entering and being burned off in Cylinder 3. Given the severity of the issue, the technician recommends replacing the entire engine to ensure the long-term reliability and extended life of your vehicle. Services completed: - Scanned vehicle and found trouble code P111A - Inspected engine and found no external coolant leaks - Used digital borescope to inspect cylinders and found coo

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 passengers, it could have resulted in a major accident or injuries. When I contacted the retailer about the warranty, they only offered to refund the part itself and refused to take responsibility for the damages caused by this defective product. I believe this part should be investigated for safety defects. When I searched online, I noticed Dorman has had similar recalls on control arms, which makes me even more concerned. I am reporting this incident to NHTSA in hopes that you will look into this part to pro

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 around the class action suits by offering the Warranty Extension but not honoring it. Mazda needs to own up to their mistake and turn this Warranty Extenions TSB into an actual Recall. Will it take an actual stall of the Mazda affected vehicle on the highway causing deaths for some corrective action to be taken?

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.

Make sure the display shows a warning when the camera fails and the vehicle drives backwards. There may be children behind the car.

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 never overheated. But the dealer lowered the coolant and had the engine overheat a little bit just to generate the computer code the warranty dept was requiring. This itself was an unnecessary additional potentially damaging scenario, completely unnecessary when the crack in the cylinder head was already found, and the coolant leak is clearly present. After all this, Mazda lowered their original quote from $10K to $6K and expect me to pay this to replace the engine. I called the corporate (customer rel

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 the possibility of losing control of the vehicle.

I entered my vehicle one day to find what looked to be cracks in the top left hand corner of my center display infotainment screen. However, they appeared to be internal and could not be felt. After doing some research, I came across Service Alert SA-008/18 from Mazda which covered this issue on 2016-2018 CX-9s, among other models. I also found a memo dated May 6, 2020, which detailed an extension of warranty service for these internal display cracks. I took my vehicle to my Mazda dealership who inspected the vehicle and told me they would be filing a claim with Mazda for the repair of the screen since there wasn't a current recall for this issue on my vehicle. Mazda agreed to partially cover the replacement with me being responsible for a $543 copay. I have spoken to Mazda Corporate about this resolution being unacceptable. This issue is a known manufacturing defect on earlier models of the CX-9, and it is obviously still an issue on the 2019 models. I explained to them that this was in no way a fault of my own and I feel that the screen should be replaced at no charge to me, which was the procedure for those affected by this issue with 2016-2018 models. As of right now, the cracks only affect the top left corner of my screen but I have read of many instances where vehicle owners had the cracks continue to spread, which I feel is very distracting to the driver.

On the last week of May, my car started experiencing sputtering and stalling out problems. I made an appointment at Mazda dealership for june 6th.meantime my husband checked all fluids and coolant was low so we topped up. Car was being driven very limited due to safety concerns. Then While driving on the freeway my car displayed a “excessive engine temperature, engine output will be limited” immediately my car reduced speed from about 65mph to under 15 mph while having my whole family including myself and 4 children in the car. We almost got hit by several cars while trying to get over to the shoulder. Once pulled over to the shoulder my husband came and followed me home on the back streets. Once again checked fluids and coolant again was back low this time empty. So In a day it completely had no coolant left. When taken into Mazda dealership for the appointment, customer service was so horrible I ended up leaving and taking my car to a 3rd party service center. Was advised to have a Hydrocarbon test on cooling system that measured at zero, then advised to take it for a diagnostic due to the sputtering, stalling and coolant leak, where they ultimately determined the coolant was leaking into combustion chamber &/or intake system.

2019 Mazda CX-9 GT Infotainment Screen is spidering / cracking in the upper right-hand corner making it difficult to see information on the screen. This appears to be an ongoing problem with the design / components of the infotainment screen. I note a May 2020 TSB / Dealer Notification campaign which extended the warranty coverage period to 7 years for this exact same issue in 2016-2017 model year CX-9s. The 2019 model year cars have the exact same problem and Mazda is not covering the issue.

Hi, I have a 2019 Mazda CX-9. It is a certified pre-owned vehicle we purchased in October 2020. Upon going out to our car yesterday, June 12th, 20212, I noticed that the top left of the center console screen appeared to be damaged. I was perplexed because the car was locked and it wasn't there previously. As I touched the screen, I realized that cracks/peeling were all internal within the screen. I immediately decided to Google the issue to see if others have had similar experiences, and I found dozens and dozens of examples. Separately, there is a safety alert on the issue from Mazda (see here: https://static.nhtsa.gov/odi/tsbs/2018/MC-10134920-9999.pdf). Additionally, the issue has gotten so bad that Mazda has issued a warranty extension for this specific problem (see here: https://static.nhtsa.gov/odi/tsbs/2020/MC-10176061-0001.pdf). The extension only is covering cars made through 4/29/17, and ours was made after that so is not formally covered at the moment. I called Mazda customer service, where both my cars are formally registered, to discuss the issue. They told me the best they could offer was for me to take it to a dealer, have the dealer attempt to have it covered under warranty, and Mazda corporate warranty will respond, but their response is final. If they say it's not covered, there is no debating it. As you can see from the picture, this is the exact issue that is currently being covered free of charge in earlier models. A recall should be issued or Mazda shoul

Suspension
Filed Feb 2, 2022FL

The front end especially on the drivers side front suspension. The noise seems to be coming from the control arms and ball joints area. I have reported this to the dealership many times since purchasing the vehicle new. They continue to say that there is no issue but the noise is not going away. I believe it is associated with this TSB but no recall has been made. I am very concerned as the steering feels looser than usual and may cause an accident. TSB 10170655 - DESCRIPTION Some vehicles may exhibit one or more of the following noises from the front suspension: 1. A creaking noise from under the front of the vehicle (front lower arm bushing) when driving over bumps at approximate 12 - 25 mph (20 - 40 Km/h). The noise occurs when the road surface is wet or after the vehicle has been washed. The noise becomes more noticeable as the bumps get higher. The creaking noise is caused by the front lower arm bushing (A) making a stick-slip noise during wet road conditions. 2. A clunking noise from the front coil spring when driving over bumps. The clunking noise is due to stick- slip between the front strut bearing (B) and the coil spring (C). 3. A popping noise from the bump stopper (D) when driving through gutters.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
