Jeep Grand Cherokee diesel EGR cooler can crack, causing fire

NHTSA campaign 20V699000 · Reported 2020-11-12 · Chrysler (FCA US LLC)

critical How serious is it? About this label

Serious — a fire can start inside the engine, and while the notice does not tell you to park the vehicle, you should get it repaired as soon as parts are available.

What's wrong, in plain English

On Grand Cherokees with the 3.0L diesel engine, the part that cools exhaust gases before they are routed back into the engine can crack. Hot coolant then turns to vapor, gets pulled into the engine's air intake, and can catch fire inside it. Dealers will replace the cooler and inspect the intake manifold, replacing it if needed. Parts were not available when the first letter went out, so owners were sent an interim notice and a second one later.

What you should do

1. Look up your VIN at nhtsa.gov/recalls to confirm your diesel Grand Cherokee is covered. 2. Contact your Jeep dealer to check parts availability and book the repair, or call FCA at 1-800-853-1403 (recall W79). 3. The EGR cooler replacement and any intake work are free.
