1993 Dodge Dynasty — 2.5L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1993 Dynasty 2.5L.

Body PASSENGER CAREngine 2.5LTransmission Automatic 3-spd

The 1993 Dodge Dynasty is an AC-platform passenger car motivated by a 2.5L engine and a 3-speed automatic transmission, returning an EPA-estimated 21 combined mpg. Routine maintenance for this setup requires 4.5 quarts of filter-inclusive oil across acceptable viscosities like 5W-30, 10W-30, or 15W-40, though ownership prospects are more complicated than its straightforward powertrain specifications suggest. Recording 111 total owner complaints—predominantly regarding hydraulic service brakes alongside a single recall—this model year sits just past the model's worst year in 1992, which saw 169 complaints, meaning researchers will find it improved but still carrying notable reliability concerns before the dramatic drop to just one complaint in 1994.

From the factory this vehicle uses OE oil filter 05281090AB. Note the factory engine air filter, spark plug, serpentine belt and thermostat are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 30,000 mi; coolant every 7,500 mi. The big-interval services (every 7,500 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1993 Dodge Dynasty sits at a turning point in the model's federal record. Complaints peaked at 169 in 1992, then dropped to 111 in 1993—still elevated but trending downward. Recalls fell from two in 1992 to just one in 1993, while investigations doubled to two, suggesting regulators were still scrutinizing the car. The high number of TSBs (42) indicates that Chrysler was actively issuing fixes for known issues, particularly in brakes (26 complaints) and powertrain (21 complaints). After 1993, complaints and TSBs collapsed to near zero, implying that the 1993 model year was the last to carry the generation's most persistent problems. Given the two crash complaints and the fact that later years are far cleaner, the 1993 is a riskier buy than a 1994 or 1995, though it is an improvement over the peak-problem 1992. **Unless you can verify that the major brake and powertrain TSBs have been applied, this is not a recommended year to purchase.**
