Dodge K30 problems
The third generation of the C/K series is a range of trucks that was manufactured by General Motors from the 1973 to 1991 model years. Serving as the replacement for the "Action Line" C/K trucks, GM designated the generation under "Rounded Line" moniker. Again offered as a two-door pickup truck and chassis cab, the Rounded Line trucks marked the introduction of a four-door cab configuration.
Marketed under the Chevrolet and GMC brands, the Rounded Line C/K chassis also served as the basis of GM full-size SUVs, including the Chevrolet/GMC Suburban wagon and the off-road oriented Chevrolet K5 Blazer/GMC Jimmy. The generation also shared body commonality with GM medium-duty commercial trucks.
In early 1987, GM introduced the 1988 fourth-generation C/K to replace the Rounded Line generation, with the company beginning a multi-year transition between the two generations. To eliminate model overlap, the Rounded Line C/K was renamed the R/V series, which remained as a basis for full-size SUVs and heavier-duty pickup trucks. After an 18-year production run (exceeded only in longevity by the Dodge D/W-series/Ram pickup and the Jeep Gladiator/Pickup), the Rounded Line generation was retired after the 1991 model year.
From 1972 to 1991, General Motors produced the Rounded Line C/K (later R/V) series in multiple facilities across the United States and Canada. In South America, the model line was produced in Argentina and Brazil, ending in 1997.

Common Dodge K30 problems
Dodge K30 owners have reported several common problems with their vehicles, which can be categorized into engine, fuel system, and emissions system issues.
- Engine Issues: The main bearing web crack is a common problem in both 6.2L and 6.5L engines. This issue is reportedly fixed with a combination of improved higher nickel cast iron alloy and lower block re-design, including a main bearing girdle. This feature is present in the new-for-2007 AM General GEP P400 6500 Optimizer enhanced 6.5L diesel. Crank failure is also a concern, which can be attributed to age failures of the harmonic balancer, the vibration-damped accessory drive pulley, or the dual-mass flywheel.
- Fuel System Issues: The fuel system in Dodge K30s is a simple design, with a mechanical or electric fuel lift pump feeding a Stanadyne rotary distributor injection pump at low pressure. The distributor injection pump controls both metering and high-pressure fuel delivery to the fuel injectors via internal precision hydraulic pumps. However, the pump-mounted driver (PMD) can overheat due to thermal failures, which can be resolved by relocating the PMD to a lower-heat environment or using an extension harness and heat-sink kits.
- Emissions System Issues: Dodge K30s with the 6.7-liter engine have experienced problems with the Variable Geometry Turbocharger (VGT), which can cause turbo lag and issues with the exhaust brake. Additionally, the introduction of the Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) emissions systems can lead to problems that can cause the truck to go into limp mode until a repair is made. These issues are common in trucks with under 100,000 miles, and it is essential to ensure that any remaining factory warranty covers emissions equipment up to 50,000 miles. Removing federally mandated emissions equipment from any vehicle is illegal and voids the remaining factory warranty.
It is crucial to address these common problems when considering purchasing a Dodge K30, ensuring that any recall work has been completed and that the turbo, exhaust brake, EGR, and DPF systems are working correctly.
