Vehicle Reliability References
What owners actually report — straight from the public record.
These pages are built from the NHTSA Office of Defects Investigation databases — the complaints owners file and the recalls manufacturers issue. We don’t score cars or guess. We show you which systems get reported most on a given vehicle, then link you to the exact trouble codes and repair guides that cover those systems. It’s the diagnostic-first version of a buyer’s guide: here’s what tends to break, and here’s how you’d confirm and fix it.
Dodge Ram 2500 (2003–2007)
The 5.9L Cummins common-rail era
2,690 complaints · 10 recalls
The famously bulletproof 5.9 barely registers — the complaints are steering “death wobble” and the truck around the engine.
See the report →Ford F-250 Super Duty (2003–2007)
The 6.0L Power Stroke era
1,055 complaints · 10 recalls
Engine & cooling is the #1 reported area — the exact reputation the 6.0L earned. EGR cooler, oil cooler, and head studs are the watch list.

The LML Duramax era
962 complaints · 10 recalls
The LML’s CP4.2 fuel pump is the headline risk. The high airbag count is the industry-wide Takata recall, not a truck-specific defect.
See the report →Data source: U.S. National Highway Traffic Safety Administration (NHTSA), public-domain complaint and recall databases, retrieved June 2026. Complaint counts reflect what owners chose to report — they are not a scientific failure rate and don’t account for how many of each vehicle were sold. Always get a pre-purchase inspection before buying a used vehicle.
