NOTE: This recall applies only to the above front wheel drive vehicles equipped
with a 2.0L engine (sales code ECN) or 2.4L engine (sales code ED3).
NOTE: Some vehicles above may have been identified as not involved in this
recall and therefore have been excluded from this recall.

IMPORTANT: Some of the involved vehicles may be in Dealer vehicle
inventory. Dealers should complete this recall service on these vehicles before
retail delivery. Dealers should also perform this recall on vehicles in for service.
Involved vehicles can be determined by using the VIP inquiry process.

Subject
Some of the above-involved vehicles may exceed NOx (Oxides of Nitrogen)
emission level standards due to loss of catalytic converter efficiency due to the
combination of precious metal usage, washcoat technology and sulfur levels in the
fuel.

Repair
Replace the catalytic converter and update the Powertrain Control Module (PCM)
software.
NOTE: Perform the Inspection Procedure to confirm that the last eight digits
of the Vehicle Identification Number (VIN) matches the engine identification
number before proceeding with the Service Procedure. If the engine has been
replaced (numbers do not match) do not perform the U67 recall, unless it is a
certified MOPAR engine built specifically for this vehicle application.
Updating the PCM software on a vehicle with an incorrect replacement engine
will result in a no-start condition which cannot be undone. U67 cannot be
completed on a vehicle with an incorrect replacement engine until the vehicle
is returned to the original equipment configuration.

Special Tools
The following special tools are required to perform this repair:
➢ NPN

Inspection Procedure
NOTE: 2.4L engines ONLY, confirm that the last eight digits of the Vehicle
Identification Number (VIN) matches the engine identification number before
proceeding with the Service Procedure. If the engine has been replaced
(numbers do not match) do not perform the U67 recall, unless it is a certified
MOPAR engine built specifically for this vehicle application. Updating the
PCM software on a vehicle with an incorrect replacement engine will result in
a no-start condition which cannot be undone. U67 cannot be completed on a
vehicle with an incorrect replacement engine until the vehicle is returned to
the original equipment configuration.
1. Raise and support the vehicle.

BELLY PAN

2. If equipped: Remove the engine
compartment belly pan (Figure 1).
3. Compare the engine identification
number to the last eight digits of
the VIN (Figure 1).
NOTE: The engine identfication
number is stamped on the
bottom rear of the engine near
the transmission.

Pan

LAST 8 DIGITS OF VIN

4. Does the engine identification
number match the last eight digits
of the VIN?
➢ YES: If numbers match, leave
the belly pan off if removed,
lower the vehicle, then continue
with the Service Procedure.
➢ NO: If numbers do not match,
do not perform the Service
Procedure. Install the belly pan
if removed then lower the
vehicle. Claim the inspection
LOP.

Service Procedure
A: Replace Catalytic Converter:
WARNING: The normal operating temperature of the exhaust system is
very high. Therefore, never work around or attempt to service any part of
the exhaust system until it is cooled. Special care should be taken when
working near the catalytic converter. The temperature of the converter
rises to a high level after a short period of engine operation time.
AIR CLEANER INLET

1. Open the engine compartment hood.

2. (MK) Jeep Patriot, Jeep Compass
and (PM) Dodge Caliber vehicles:
Remove the air cleaner inlet in order
to access the battery (Figure 3).

3. (MK) Jeep Patriot, Jeep Compass
and (PM) Dodge Caliber vehicles:
Disconnect and isolate the negative
battery cable from the battery.
