6.7L Cummins Recalls
Released October 2007, the G30 recall of the 6.7L Cummins diesel recommends replacement of the engine's oxygen sensor module and reprogramming of the ECM (engine control module). The G30 recall affects 2007/2008 model trucks built August 20th, 2007 & earlier (approx. 74,000 trucks affected). The oxygen sensor module on these trucks was found to be prone to premature failure, and the on board diagnostics (OBD II) system often does not detect the failure. The new ECM tune also enhances engine performance & driveability while reducing the accumulation of soot in the diesel particulate filter (reduces risk of DPF clogging).
Cummins/Dodge released the J35 recall for the 6.7L Cummins to address a variety of issues, including:
• Soot build up and clogging of the turbocharger, EGR (exhaust gas recirculation) valve, and DPF (diesel particulate filter).
• Poor fuel economy, lack of performance caused by clogging of key emissions components.
• Failure of emissions components due to clogging & excessive soot production.
• False illumination of the check engine light (malfunction indicator light).
When emissions components become clogged by soot, they function incorrectly & can negatively impact fuel economy & engine performance. The J35 recall affects 6.7L Cummins diesels model years 2007 thru 2009. The recall requires reprogramming of the ECM (engine control module), a simple procedure that can be performed at your local Dodge service station. The new ECM program alters, amongst other parameters, the active regeneration strategy.
If your engine has not received the updated ECM program or oxygen sensor module, contact your local Dodge dealer. If your truck is suffering from poor fuel economy or you have had to replace the DPF, EGR, or turbocharger, contact your local Dodge dealer to confirm whether or not your truck requires the update. Dodge diesel owners who are affected by the recall should have received an official notice, but we have found that not all owners were made aware of the recall.
