The picture
Is the Mazda Millenia or Honda Accord more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Mazda Millenia
The Mazda Millenia is an older luxury sedan that, based on NHTSA data, shows a moderate rate of owner complaints concentrated in the engine and cooling system, with additional reports of transmission and electrical gremlins. Owners describe stalling, surging, and erratic shifting, which suggests the car may require frequent mechanical attention. While it has no recalls, the nature of the complaints points to a vehicle that could be costly to maintain and potentially unreliable for daily use.
Honda Accord
The Honda Accord is a popular midsize sedan with a much higher volume of complaints, but this is partly due to its longer production run and larger owner base. The data reveals significant issues with the engine, electrical system, and forward collision avoidance features, including reports of sudden power loss and false braking. Despite its reputation for reliability, the Accord in this dataset shows that modern electronic systems can be a source of frustration and safety concerns.

What actually goes wrong
The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.
Mazda Millenia

- 02POWER TRAIN13
- 03AIR BAGS8
- 04ELECTRICAL SYSTEM7
- 05SUSPENSION6
Owners report persistent fuel system problems, stalling at speed, and the need for repeated decarbonization and sensor replacements. This suggests the engine may suffer from carbon buildup and sensor failures, leading to poor driveability and potential stalling.
Transmission issues are described, including the car unexpectedly going into reverse or lurching forward at full throttle when shifted into drive. This indicates possible transmission control module failures or internal mechanical problems that could be dangerous.
The airbag warning light frequently illuminates, and dealers have replaced multiple components without a permanent fix. This points to an intermittent electrical fault in the airbag system, which could mean the airbags may not deploy in a crash.
Battery acid fumes have corroded engine components and entered the cabin, indicating a possible battery or charging system defect. This can lead to electrical failures and health concerns from fumes.

- 04UNKNOWN OR OTHER725
- 05SERVICE BRAKES592
Owners report unusual noises and sudden loss of power with multiple warning lights, including brake and ABS alerts. This suggests possible engine or drivetrain failures that could leave the driver without propulsion.
There are reports of tire pressure monitoring system (TPMS) warnings followed by tire failure, and rodent damage to wiring harnesses. These issues point to potential vulnerabilities in the electrical system that can lead to safety-critical failures.
The system has triggered false alerts and even applied brakes unexpectedly on open roads, and there are intermittent problems with adaptive cruise control and lane keeping. This can be alarming and may increase the risk of rear-end collisions.
While not detailed in the sample, the high number of complaints in this category suggests issues with braking performance or the antilock brake system, which is critical for safety.

Buyer analysis
Mazda Millenia or Honda Accord: which should you buy?
The Mazda Millenia has far fewer complaints per year (24.0) compared to the Honda Accord (443.8), but the Millenia's issues are more likely to be mechanical and potentially dangerous, such as stalling and unintended acceleration. The Accord's higher volume is partly due to its popularity, but the nature of its complaints, especially with electronic safety systems, indicates that modern features can be a double-edged sword.
Key differences
- The Millenia has no recalls, while the Accord has 38, indicating that Honda has acknowledged more widespread defects.
- The Millenia's complaints are mostly about engine and transmission failures, while the Accord's top issues involve electrical and driver-assistance systems.
- The Accord has a much higher rate of complaints per year, but this is partly due to its larger sales volume and longer production run.
- The Accord's forward collision avoidance system has been reported to activate falsely, which can be a safety hazard, whereas the Millenia lacks such systems.
- Inspect the engine for signs of carbon buildup and check for any history of fuel injector or knock sensor replacements.
- Test the transmission for smooth shifting and be wary of any hesitation or unexpected gear changes.
- Check the forward collision avoidance system for any warning lights or previous repairs, and test it in a safe area.
- Look for any signs of electrical issues, such as intermittent warning lights or problems with the TPMS.
Before you buy
- For the Millenia, have a mechanic perform a compression test and inspect the fuel system for leaks or contamination.
- For the Accord, verify that all recalls have been performed and ask for service records related to the engine and electrical system.
- Test drive both vehicles at highway speeds to check for stalling, surging, or unexpected braking.
- Check the airbag warning light on the Millenia and the forward collision warning on the Accord during the test drive.
- Consider a pre-purchase inspection by a specialist familiar with each model's known issues.
