25V6850002025-10-10

EQUIPMENT

Ford Motor Company (Ford) is recalling certain 2016-2019 Lincoln MKC, 2016-2023 Explorer, 2019-2020 Fusion, 2019-2024 Ranger, 2020-2022 Lincoln Corsair, Escape, 2021-2024 Bronco, Bronco Sport, and 2022-2024 Maverick vehicles. The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.

Consequence

An electrical short circuit can increase the risk of a fire.

Remedy

Owners are advised not to plug in their block heater until the vehicle is remedied. Dealers will replace the block heater, free of charge. Interim letters, notifying owners of the safety risk, were mailed December 3, 2025. Additional letters will be sent once the final remedy is available, anticipated February 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25SA4. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on October 15, 2025.

25V4550002025-07-07

FUEL SYSTEM, GASOLINE

Ford Motor Company (Ford) is recalling certain 2021-2023 Bronco, Explorer, Lincoln Aviator, F-250 SD, F-350 SD, F-450 SD, F-550 SD, 2021-2022 Lincoln Navigator, Mustang, F-150, and 2022 Expedition vehicles. The low-pressure fuel pump may fail, which can result in an engine stall while driving.

Consequence

An engine stall increases the risk of a crash.

Remedy

The remedy is under development. Interim notification letters notifying owners of the safety risk were mailed July 16, 2025. Second letters will be sent once the remedy is available, anticipated March 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S75.

25V4420002025-06-27

A software error may cause the rearview camera to display a blank image, or the image may remain on the display after the backing event has ended.

Consequence

A rearview camera that displays a blank image can reduce the driver's view behind the vehicle. A rearview image that continues to be displayed after the vehicle is shifted out of reverse may distract the driver. Both of these situations can increase the risk of a crash.

Remedy

Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed September 4, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S72.

How We Calculate Reliability Scores

Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.

Key Ranking Factors

1

Complaint Severity

NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

Recall Impact

Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.

4

Issue Diversity

Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.

Scores are grouped into four tiers:

  • 80–100: Excellent — Top-tier reliability, minimal issues
  • 60–79: Good — Reliable with some minor concerns
  • 40–59: Mixed — Notable issues, research before buying
  • 0–39: Risky — Significant problems, proceed with caution

Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
