The picture
Is the Mazda Millenia or FORD F 150 more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Mazda Millenia
The Mazda Millenia, a late-1990s to early-2000s sedan, shows a moderate complaint rate of about 24 per year over three years, with no recalls. Owners report persistent engine and fuel system issues, including stalling and hesitation, as well as transmission anomalies like unintended reverse or sudden forward lurching. Airbag warning lights and electrical gremlins, such as battery fumes and self-actuating door locks, add to the ownership burden, suggesting a vehicle that may require frequent repairs and careful maintenance.
FORD F 150
The Ford F-150, a full-size pickup spanning a decade, has a much higher complaint volume (over 11,000) and 145 recalls, reflecting its popularity and long production run. The dominant issues are transmission problems, particularly hard shifting and sudden power loss, along with electrical system failures like camera malfunctions and battery cable issues. Exterior lighting and engine problems also appear frequently. While the F-150 is a workhorse, these reports indicate that certain model years, especially those with the 10-speed automatic, may have significant reliability concerns.

Owners report stalling at speed, hesitation, and a need for repeated decarbonization and fuel injector cleaning. One owner experienced a shorted knock sensor, indicating potential engine management issues that could lead to performance problems and costly repairs.
Transmission anomalies are described, such as the vehicle continuing in reverse when shifted to drive, and a sudden full-throttle lurch forward when the brake is released. These are serious safety concerns that could cause unintended movement and accidents.
The airbag warning light frequently illuminates, and dealers have replaced the airbag, cable harness, and control module without a permanent fix. This suggests an intermittent electrical fault that may leave the airbag system unreliable in a crash.
Battery acid fumes have been reported spilling onto engine components, causing corrosion and sometimes entering the cabin. This indicates a potential battery or charging system defect that could lead to electrical failures and health concerns.

The 10-speed automatic transmission is a major source of complaints, with owners experiencing hard and delayed shifts, jerking, clunking, and even sudden loss of power and shutdown. These issues can be dangerous in traffic and may require transmission replacement.
Electrical problems include warning messages for front camera malfunction and pre-collision assist being unavailable, which appear every time the truck is started. This suggests a persistent sensor or software issue that could disable safety features.
Headlight-related recalls and complaints are common, with owners reporting failures that reduce visibility at night. This is a safety concern, especially on dark roads.
Engine issues are also reported, though less frequently than transmission problems. Owners have experienced stalling and other performance issues, which can be alarming and lead to breakdowns.
“I started noticing hard and delayed shifts from 7th into 8th gear. My RPM's were not increasing when this happened, and then on a very crowded major road I lost all power, vehicle shut off and drifted, then started up and jerked again very hard. This failure…”

Buyer analysis
Mazda Millenia or FORD F 150: which should you buy?
The Mazda Millenia has far fewer complaints per year (24 vs. 1,131) and no recalls, indicating a lower frequency of reported issues. However, the Millenia's problems, such as transmission lurching and airbag failures, are serious safety concerns. The F-150's high volume reflects its popularity, but the transmission and electrical issues are widespread and may affect many vehicles.
Key differences
- The Millenia has no recalls, while the F-150 has 145, indicating a higher rate of factory-identified defects.
- Transmission issues on the Millenia involve unintended movement (reverse or lurch), whereas F-150 problems are more about harsh shifting and power loss.
- Airbag warning lights are a common Millenia issue, while F-150 electrical problems often involve driver-assist systems like cameras.
- The F-150's exterior lighting problems are a safety concern, but the Millenia has no such reports.
- Check for a history of repeated engine decarbonization or fuel injector cleaning, which may indicate a chronic fuel system issue.
- Test the transmission carefully, especially for any hesitation or unintended movement when shifting from park to drive or reverse.
- Look for any transmission shudder or hard shift during a test drive, especially between 4th and 6th gears, and ask if the transmission has been serviced or replaced.
- Check if the front camera or pre-collision assist warnings appear on startup, as they may indicate a persistent electrical problem.
Before you buy
- Have a mechanic perform a pre-purchase inspection, focusing on the engine and transmission for both vehicles.
- For the Millenia, ask for service records related to fuel system cleaning and airbag repairs.
- For the F-150, check the vehicle's recall status and ensure all recalls have been addressed.
- Test drive both vehicles at various speeds, including stop-and-go traffic, to feel for transmission issues.
- Check the electrical system by starting the vehicle and observing any warning lights or malfunctions.
