Certain 2014-2020 Jeep Grand Cherokee and 2014-2019 Ram 1500 vehicles equipped with 3.0L diesel engines, could experience high-pressure fuel pump failure. If the pump fails while the vehicle is being operated, drivers will experience an unexpected loss of engine power and an increased chance of an accident.

In February 2022, Fiat Chrysler Automobiles (FCA) Technical Safety and Regulatory Compliance (TSRC) organization started an investigation into Jeep Grand Cherokee and Ram 1500 trucks, after receiving field reports that the fuel pump in some vehicles were prematurely failing. An investigation of the stall patterns and vehicle histories showed that the affected trucks were equipped with Bosch CP4.2 high-pressure fuel pumps (HPFP).

According to the defect report, a failure inside the fuel pump could introduce internal debris that could build up and cause fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which could contribute to a vehicle to crash. The suspect period began on June 12, 2013, when 3.0L Diesel engines with suspect HPFPs were introduced into vehicle production, and ended on December 13, 2019, when 3.0L Diesel engines with suspect HPFPs were no longer used in vehicle production.

Warning signs that your vehicle may be experiencing this problem include:
Drivers may notice a Malfunction Indicator Lamp, a service Electronic Throttle Control indicator, a fuel leak at the HPFP, or excessive noise from the HPFP.

FCA US is aware of 215 customer assistance records, 1,061 warranty claims, and three field reports that could be related to this issue.

Owners receiving notices will be asked to return to their dealers to have the HPFP replaced. Dealers will also inspect the entire fuel system and replace components as necessary. FCA’s number for this recall is Z46 and the NHTSA campaign number is 22V-406.

Chrysler (FCA US, LLC) will be contacting owners of certain Chrysler, Alfa Romeo, and RAM vehicles for a problem affecting the fuel system. In total, approximately 236 000 vehicles are being recalled.

2020-2021 Alfa Romeo Stelvio and Alfa Romeo Giulia vehicles fuel line sensor housing may crack and leak fuel. NHTSA Campaign Number: 21V-878

The problem was traced to September 11, 2020, when defective fuel sensors were introduced into vehicle production, and ended on May 25, 2021, when the fuel sensors from the suspect batches were no longer used. The suspect population was determined using part traceability and vehicle production records.

According to the defect report, a leak in the fuel line sensor may cause fuel starvation of the engine and in rare circumstances, if the leaked fuel comes in contact with an ignition source, a fire could occur. A vehicle fire can result in an increased risk of occupant injury and/or injury to persons outside the vehicle, as well as property damage. Fuel starvation could also result in an unexpected loss of motive power.

According to the defect report, the high-pressure fuel pump could fail and introduce debris into the fuel system. Fuel starvation and an unexpected loss of motive power could result without prior warning. Vehicle occupants may notice an illuminated Malfunction Indicator Lamp, a fuel leak or smell, abnormal engine noises, or a change in drive quality.

The NHTSA Office of Defects Investigation (ODI) have opened up an investigation into certain 2019-2020 RAM trucks after receiving 22 complaints and 2 field reports alleging incidents of stalling and loss of engine power. The vehicles affected are equipped with 6.7L Cummins turbo diesel engines. According to the investigation report, the complaints found that most stall/loss of motive power incident allegations occurred at speeds above 25 MPH and resulted in permanent disablement of the vehicle.

The Vehicles Affected Include:
2019-2020 Ram 2500
2019-2020 Ram 3500
2019-2020 Ram 4500
2019-2020 Ram 5500

In November 2019, FCA issued Warranty Bulletin D-19-02 to announce to its dealers a Fast Feedback Program wherein they were notified of a campaign to collect, monitor, and correct quality issues on certain 2018-2020 Ram trucks equipped with the 6.7L Cummins engine. As a result of this campaign, high-pressure fuel pumps have been collected and inspected by the manufacturer and pump manufacturer.

ODI is opening this investigation to further assess the scope, frequency, root cause, and potential safety-related consequences of the alleged defect leading to stall/loss of motive power on 2019-2020MY RAM heavy-duty trucks.

Our client purchased a 2016 Ram 1500 and was quite excited.

He had to bring in the vehicle fairly soon after purchasing as the airbag light kept coming on. It first happened at 90 miles, then 93 miles and then at 136 miles. He made a video of the light coming on to show the Ram Dealership. There was also a wind noise coming from the top of the driver door. You could hear this noise more on acceleration. The date of this visit was June 6, 2016.

The next visit was on June 22nd as he was still having the wind noise coming from the top of the driver door. There was also a problem with the center console lid not latching. They also did a software update on the PCM.

Our client was back at the dealership on August 3rd. At that time the driver’s seat would not move backwards all the way. He was also hearing a whistle in the weatherstripping on the driver’s door.

September 12th he was back in due to the air bag message coming on. The check engine light came on the touch screen and the air conditioning turned off. He is disappointed as the vehicle never gets over 23 MPG.

The next visit was on November 20th because while driving the throttle control light came on and the check engine light, too. He could not go over 30 MPH.

The air bag light coming on intermittently is the reason he drove the vehicle to the authorized dealership on January 24, 2018.

It was at the point that he called the Law Office of Barry L. Edzant, a California Lemon Law Attorney with over 30 years experience. During the free consultation, Barry, requested that some documents be emailed to him so he could review them. Soon thereafter our client signed up with our firm. A letter was send to FCA, USA demanding they buy back the vehicle under the California Lemon Law.

FCA, USA agreed to buy back the 2016 Ram 1500. They reimbursed our client for their down payment, all monthly payments, their registration, the payoff on the vehicle minus a mileage deduction allowed under the Lemon Law. FCA, USA also paid the attorney fees.

Our client was very pleased with the outcome.

Some 2014-2016 Jeep Grand Cherokee and 2014-2018 RAM 1500 vehicles equipped with 3.0L diesel engines may have been manufactured with crankshaft tone wheels that could experience magnetic signal material delamination.

The magnetic material attached to the tone wheel provides a signal to the crankshaft position sensor. If this material delaminates, the engine will lose its ability to synchronize injector pulses and cam timing. Loss of crankshaft position can result in an engine stall and the inability to restart. The problem can occur without prior warning.

The remedy for this condition is not currently available. Dealers will stop the engine from stalling by updating the powertrain control module software to maintain vehicle propulsion by reading the camshaft position signal in the event that the crankshaft position signal is lost. If tone wheel failure occurs, the engine warning light will illuminate but the vehicle will not stall.

The recall to update the powertrain control module software is expected to begin in October. FCA’s number for this recall is W58 and the NHTSA campaign number is 20V-475.

Chrysler will be contacting the owners of certain 2019-2020 Ram 2500 and 2019-2020 Ram 3500 pickups equipped with six-speed automatic (68RFE) transmissions, because of a problem affecting the transmissions in their trucks.

According to the defect report, these vehicles could experience a build up of pressure and heat inside the transmission strong enough to expel fluid from the dip stick tube. If the fluid comes in contact with the turbocharger or other ignition sources within the engine compartment, it could lead to a fire. Vehicle occupants may notice odd smalls, noises or transmission surging prior to a vehicle fire.

Dealers will fix the problem by replacing the transmission valve body separator plate and reprogramming the powertrain control module. Chrysler’s number for this recall is W03 and the NHTSA campaign number is 20V-043.

Chrysler will be contacting the owners of certain 2014-2019 Ram 1500 and 1500 Classic Pickup trucks equipped with 3.0L Eco Diesel engines because of a vehicle safety problem.

According to the defect report, the Exhaust Gas Re-circulation (EGR) coolers are susceptible to thermal fatigue and could crack over time. Th crack could allow pre-heated vaporized coolant to enter the EGR system and could combust inside the intake manifold, causing a vehicle fire. Drivers may be alerted there is a problem through a noticeable loss of coolant, lack of heater function and potentially a Malfunction Indicator Lamp.

Owners receiving notices will be asked to return to their dealerships to have the EGR cooler replaced. Dealers will also inspect and replace the intake manifold as necessary. Chrysler’s number for this recall is VB1 and the NHTSA campaign number is 19V-757.

Chrysler will be contacting a small number of 2016-2017 RAM 1500 owners regarding a problem affecting their vehicles power train. According to the defect report, the differential retaining screw pin could become loose and contact the bearing cap. If the pin comes out of position, the differential pinion spider gears, the loose screw or the pin itself could make contact with components inside the differential and cause it to break and/or lock up.

Dealers will inspect and replace the differential pin retaining screw in all affected vehicles. If the inspection finds the retaining screw loose or damaged, the entire rear axle assembly will be replaced. Owners wanting more information about the problem are asked to contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is T20 and the NHTSA campaign number is 17V-198.
