2003 Dodge Caravan — 3.8L V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 Caravan 3.8L V6.

Body VANEngine 3.8L V6Transmission Automatic 4-spd

The 2003 Dodge Caravan is a full-size RS-platform van powered by a 3.8L V6 paired with a four-speed automatic transmission, delivering EPA-estimated fuel economy of 16 city and 23 highway mpg while requiring 5 quarts of 5W-30 API-rated oil for service. With 195 owner complaints logged—far below the model’s 1996 peak of 1,647—this year stands as one of the more dependable entries in the Caravan’s 1990–2017 run, though its nine recalls and recurring steering-related issues underscore the need for diligent maintenance to mitigate its most persistent reliability concerns.

From the factory this vehicle uses a BCI 34 · 500 CCA battery, OE oil filter 04105409AE. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 100,000 mi; coolant every 100,000 mi. The big-interval services (every 100,000 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 2003 Dodge Caravan records 195 complaints, 9 recalls, 1 investigation, and 70 TSBs, placing it in a clear downward arc of owner-reported issues that began after the mid-1990s peak (1,647 complaints in 1996) and continued through the early 2000s (526 in 2000, 260 in 2001, 256 in 2002). Compared to its immediate neighbors, 2003 is notably cleaner than 2002 across every category — fewer complaints, fewer recalls, and a sharp drop in investigations from 5 to 1 — and it outperforms the broader 1996–2000 stretch on nearly every metric, with recalls also well below the 15–16 issued during the 1996–1997 spike. The leading complaint clusters are steering (33), hydraulic service brakes (24), electrical system (15), and powertrain (13), with 13 crash-flagged and 5 fire-flagged complaints, but the data does not specify root causes for these categories. The 9 recalls still warrant pre-purchase verification, and the 70 TSBs suggest ongoing manufacturer attention to refinements even at this relatively quiet point in the generation. On balance, 2003 represents one of the stronger used-buy candidates within this generation's federal record — it sits near the low-complaint trough of the early-2000s arc and is a reasonable year to consider, provided the recall list and steering/brake items have been addressed.
