MAZDA Complaints

I was denied work on a network issue recall 3 separate times at the dealership I bought the car. The first time I was told it was because of a smell. If I clean the car, they will fix it. I noticed after they were in the car my backup camera didn’t work which I also thought might be a recall but found out it wasnt. I went ahead and cleaned it twice. I came back they alleged it smelled like cat litter and urine. I asked to speak to someone else because there was nothing in my car and I know it didn’t. There were also no stains, mold, anything like that. It smelled of cleaning products. But I took it home and scrubbed extensively even though I was confused by the comment. When I went there it was smelling like lemon. Zero stains, mold, nothing in the car but maybe a little sand and baking soda. The person went as far as to say wow the car is improved said but thry still sorta smell it and there’s stuff on the window (there wasn’t). At that point I knew I was being picked on because either they didn’t know how to fix it or didn’t want to work with me. It felt discriminatory and differential to others. I now have a super clean car but a network issue and no backup camera because of this. They claim now they fixed everything but a non-safety issue but I also still have two errors that say “telematics” and “networking issue have vehicle inspected.” I believe I have rights under NC lemon law as this is within 24 months of purchase with only 4600 miles

The car only has 70k miles on it. The engine started smoking under the hood. Immediately stopped to look. There was oil leaking but I could not see from where. I took it across the street to the Toyota dealership and had them look at it. They explained to me that there was a crack in the cylinder head and oil was leaking everywhere. Potentially causing a fire or even an explosion. The old was leaking all over the exhaust manifold and engine. I had my 2 toddlers in the car not long before this happened. This is extremely unacceptable. Currently Mazda is saying it will be 7200 to replace the engine and that cost is on me. I think that is absolutely absurd being there are only 70k miles on the car and I bought it brand new. I also kept up with all of the required maintenance.

Have a cracked windshield from a chip near the wiper area Mazda says needs to be replaced But they are on National back order Was told that when the windshield caves in or collapses Then an emergency order can be put in

This is a follow-up to my complaint 11754947, filed 8/5/2026 on the same vehicle. The defect has now been confirmed in writing by an authorized Mazda dealer. On 8/6/2026, San Francisco Mazda (repair order 1085786) diagnosed the cylinder head as the source of the engine oil leak on my 2019 CX-5 with the 2.5L naturally aspirated SkyActiv-G engine with cylinder deactivation, engine code PYUD. The dealer inspection report states: "CYLINDER HEAD LEAKING — FOUND THE CYLINDER TO BE THE SOURCE OF THE OIL LEAK." The repair estimate is $10,655.34, including a replacement cylinder head assembly, cylinder head bolts, and four gasket kits. Mileage at diagnosis was 51,483, approximately 7,000 miles per year, dealer-maintained since new. The technician inspection video shows engine oil actively dripping onto components below, and extensive burnt oil residue baked onto the metal surfaces above the engine. That residue is physical confirmation that leaking oil has been contacting hot surfaces repeatedly over an extended period. Still images from the dealer's own inspection video are attached. A burning oil odor is detectable both outside the vehicle and inside the cabin. Timeline. In April 2026 I found oil accumulating beneath the vehicle. On 5/18/2026 the same dealer (repair order 1079428) noted oil leaking from the cylinder head gasket area and from a plug near the firewall. The dealership replaced the valve cover, charged $1,218.26, and instructed me to drive 1,000 miles and return for reinspection. I drove 1,077 miles as instructed. During that period the leak persisted and progressed, developing the burning odor. On 8/6/2026 the same dealership confirmed the cylinder head as the source and confirmed the plug is not the source. I want to emphasize the safety implication of that sequence. An authorized Mazda dealer misidentified the source of an oil leak and instructed me to continue driving the vehicle for 1,000 miles. The oil was in fact reaching hot exhaust components duri

Have contacted Sport Durst Mazda in [XXX] about recall on air bags. Told me I had to drive vehicle to their shop. Told them the letter said Do Not Drive. They said they'd do the recall if I bring it to them. I live in [XXX]. I don't understand why I can not get repair done unless I drive my 2004 Mazda 6 station wagon with over 300 thousand miles on it to them. What do I need to do. This is my only vehicle since my 2017 Hyundai sonata was stolen and motor locked up with only 70 thousand miles on it 7-28-2025 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a recurring safety-related issue with my 2024 Mazda CX-90 Turbo S Premium involving the mild hybrid system. The first failure occurred at approximately 28,000 miles. While driving, the vehicle displayed multiple warning messages, including "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction." Shortly afterward, the vehicle entered a reduced-power (limp mode) condition. The loss of normal power made it difficult to safely accelerate and keep pace with surrounding traffic, creating a significant safety concern. The dealership diagnosed the vehicle and replaced the mild hybrid battery. My vehicle remained out of service for approximately one month while repairs were completed. At approximately 56,000–58,000 miles, the same problem occurred again. The vehicle once again displayed the "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction" warning messages and again entered reduced-power mode while driving. The repeated loss of power created another serious safety concern because the vehicle could not accelerate normally when merging into traffic or driving on higher-speed roads. After diagnosing the second failure, the dealership informed me that, in addition to replacing the mild hybrid battery, corrosion had been found in the wiring harness and internal wiring associated with the hybrid battery system. Those components also required replacement. Due to parts availability, my vehicle remained at the dealership for an extended period before repairs could be completed. This vehicle has experienced the same hybrid system failure twice within approximately 58,000 miles, despite the first battery having already been replaced. I am concerned that this is a recurring defect affecting the mild hybrid electrical system. A failure that causes multiple system malfunction warnings and forces the vehicle into reduced-power mode while driving increases the risk of a crash, especially when merging onto highways

The contact owns a 2015 Mazda Mazda5. The contact stated that while parked with the vehicle occupied, the contact became aware that the rear driver’s and passenger’s side seats were melting. A dealer was contacted. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 130,000.

While driving in the Interstate, a truck swerved towards my lane; I swerved into the next lane to avoid the truck hitting me and when I began to swerve my Lane Departure warning malfunctioned and caused my car to completely shut down. I immediately put my hazard lights on to hopefully avoid being hit; but, a car behind plowed right into my rear end. The police were onsite at the accident. My vehicle has been inspected by an independent service center and my insurance representative.

ISSUE 1 – UNINTENDED DECELERATION (Power Train): While driving at highway speeds (60–80 mph) with foot off accelerator for approximately 5+ seconds while coasting, the vehicle unexpectedly executes a sharp, single downshift causing sudden unintended deceleration and an RPM spike. No warning lights illuminate. Documented on 11 occasions between May 20, 2026 and July 29, 2026; incidents occurred prior to May 2026 but were undocumented. Occurs most frequently decelerating off highway exit ramps but also during general highway coasting in Houston, TX. A passenger was present during multiple incidents. Trailing vehicles are not anticipating the sudden speed reduction, creating rear-end collision risk. ISSUE 2 – FALSE BLIND SPOT / REAR RADAR ALERTS (ADAS): The Blind Spot Monitoring and Rear Radar Sensor systems generate daily false alerts — both audible and visual — when no vehicles or objects are present. Triggers randomly across varying conditions. False alerts have caused multiple aborted lane changes that were otherwise safe to execute. ISSUE 3 – LANE KEEPING ASSISTANCE (ADAS): The LKA system applies forceful steering corrections during intentional, signal-indicated lane changes, including in areas without lane markings. Occurs at highway speeds during on/off-ramp transitions. Corrections have triggered reactive maneuvers by surrounding drivers in dense traffic, causing near-collision situations. Dealer service appointment scheduled August 6, 2026.

My 2019 Mazda CX-5 with the 2.5L naturally aspirated SkyActiv-G engine with cylinder deactivation has developed a significant engine oil leak at the front of the engine, accompanied by a strong burning oil odor detectable both outside and inside the cabin. Mileage is approximately 50,000, averaging about 7,000 miles per year with all maintenance performed on schedule. The burning odor indicates engine oil is contacting hot exhaust components, creating a fire hazard. I have stopped driving the vehicle. I have taken the vehicle to two authorized Mazda dealers for this identical issue. One was unable to locate the source of the leak. The other quoted approximately $10,000 without providing a written diagnosis identifying the failed component. The vehicle is scheduled for a third dealer diagnosis on August 6, 2026. More than two weeks of dealer possession across two visits produced no identified cause. Mazda has acknowledged cylinder head cracking in this engine family. CSP11 extends powertrain warranty coverage to 10 years/120,000 miles for cylinder head repairs on the 2.5T turbo engine, and TSB 01-002/23 addresses cylinder head leaks. Mazda also revised the cylinder head casting for the 2021 model year. However, owners of naturally aspirated 2.5L vehicles with the same casting failure have been denied coverage on the grounds that the leak involves oil rather than coolant, or that their VIN falls outside the covered range. I request that NHTSA investigate cylinder head cracking in naturally aspirated 2.5L SkyActiv-G engines in 2018–2020 Mazda CX-5 vehicles. Numerous complaints describe the same pattern: oil leaking onto the exhaust manifold, burning odor and smoke, fumes entering the cabin, and failures at low mileage. This presents a risk of engine compartment fire and of sudden stalling from loss of oil pressure. The affected population appears substantially larger than the vehicles currently covered.
