Engine
6.7L Power Stroke Diesel
- Turbocharger Failure
- Description/Symptoms: Whining noise from the turbocharger, loss of power, excessive black smoke, and potentially a check engine light. Can be caused by oil starvation, debris entering the turbo, or general wear and tear.
- Solution: Replace the turbocharger. Thoroughly inspect the oil supply lines and air intake system for any blockages or debris that may have caused the failure.
- Estimated Cost to Fix: $2,000 - $4,000+
- Recalls: None Found
- Fuel Injector Issues
- Description/Symptoms: Rough idle, misfires, white or black smoke from the exhaust, decreased fuel economy, and potentially engine knocking. Can be caused by contaminated fuel, electrical issues, or general wear and tear.
- Solution: Diagnose the specific faulty injector(s) and replace them. It’s often recommended to replace injectors in sets, particularly if multiple injectors are showing signs of wear.
- Estimated Cost to Fix: $500 - $800+ per injector (parts and labor)
- Recalls: None Found
- Exhaust Gas Recirculation (EGR) Valve Problems
- Description/Symptoms: Rough idle, decreased fuel economy, black smoke, check engine light, and potential engine stalling. The EGR valve can become clogged with soot and carbon deposits, leading to malfunction.
- Solution: Clean or replace the EGR valve. In some cases, the EGR cooler may also need to be inspected and cleaned or replaced.
- Estimated Cost to Fix: $300 - $800+
- Recalls: None Found
- Diesel Particulate Filter (DPF) Clogging
- Description/Symptoms: Reduced engine performance, frequent regeneration cycles, check engine light, and eventually limp mode. Short trips and infrequent highway driving can contribute to DPF clogging.
- Solution: Attempt to force a regeneration cycle. If unsuccessful, the DPF may need to be professionally cleaned or replaced.
- Estimated Cost to Fix: $300 - $600 for cleaning; $1,500 - $3,000+ for replacement
- Recalls: None Found
6.2L V8 Gasoline
- Spark Plug Issues
- Description/Symptoms: Misfires, rough idle, reduced power, poor fuel economy, and a check engine light. Spark plugs can wear out or become fouled, leading to these issues.
- Solution: Replace the spark plugs. Consider replacing the spark plug wires or coil packs if they are also worn or damaged.
- Estimated Cost to Fix: $150 - $400
- Recalls: None Found
Transmission
6R140 6-Speed Automatic (Both Engines)
- Torque Converter Failure
- Description/Symptoms: Shuddering during acceleration, slipping between gears, difficulty shifting, and potentially a complete loss of power.
- Solution: Replace the torque converter. It’s often recommended to also inspect the transmission for any damage and replace the transmission fluid.
- Estimated Cost to Fix: $1,500 - $3,500+
- Recalls: None Found
- Harsh Shifting
- Description/Symptoms: Abrupt or jerky shifts, particularly between certain gears. This can be caused by worn valve body components, low transmission fluid, or software issues.
- Solution: Check and adjust the transmission fluid level. If the problem persists, have the transmission diagnosed by a qualified technician. It may require valve body repair or replacement, or a software update.
- Estimated Cost to Fix: $100 - $200 for fluid check and top-off; $500 - $1,500+ for valve body work
- Recalls: None Found
Suspension
- Leaf Spring Sagging/Cracking
- Description/Symptoms: Rear end sagging, poor ride quality, reduced load-carrying capacity, and potential cracking of the leaf springs. This is more common in trucks that are frequently used for heavy hauling or towing.
- Solution: Replace the leaf springs. Consider upgrading to heavier-duty leaf springs if the truck is consistently used for heavy loads.
- Estimated Cost to Fix: $500 - $1,500+ per side
- Recalls: None Found
Electrical
- Instrument Cluster Issues
- Description/Symptoms: Intermittent or complete failure of the instrument cluster, flickering displays, inaccurate readings, and potentially warning lights illuminating without cause.
