Engine and engine cooling

23V41100080,629 vehicles affected

The problem
Chrysler (FCA US, LLC) is recalling certain 2014-2019 Ram 1500 and 2014-2020 Jeep Grand Cherokee vehicles equipped with 3.0L Diesel engines. The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
The risk
An engine stall can increase the risk of a crash.
The fix
Dealers will update the powertrain control module software to maintain vehicle propulsion, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed August 3, 2023. Some owner notification letters were mailed October 31, 2023. The remaining owner notification letters will be mailed at a future date, anticipated July 2024. Owners may contact FCA US, LLC customer service at 1-800-853-1403.

Engine and engine cooling: diesel

20V47500058,016 vehicles affected

The problem
Chrysler (FCA US LLC) is recalling certain 2014-2018 Ram 1500 and 2014-2016 Jeep Grand Cherokee vehicles equipped with 3.0L diesel engines. The crankshaft position sensor tone wheel may delaminate causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.
The risk
An engine stall can increase the risk of a crash.
The fix
FCA US will notify owners, and dealers will update 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, free of charge. Owner notification letters were mailed on May 13, 2021. Owners may contact FCA US customer service at 1-800-853-2002. FCA US's number for this recall is W58.

Engine and engine cooling: gas recirculation valve (egr valve)

The fix
Chrysler will notify owners, and dealers will replace the EGR cooler, free of charge. Dealers will also inspect and, as necessary, replace the intake manifold. The recall began April 16, 2020. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is VB1.

2014-2019 Ram 1500 EcoDiesel trucks. The court-approved settlement provides coverage relating to the EGR cooler issue. I contacted Ram/Stellantis and the dealership and requested that they review my VIN and the applicable recall and extended warranty information. I was told that the applicable coverage was not showing or was not being honored. I was also given manufacturer case number [redacted]. I am requesting that NHTSA review whether my VIN is covered by the applicable EGR recall, warranty extension, or court-approved settlement and whether my previous January 2023 EGR repair affects eligibility for later applicable coverage. My vehicle currently has approximately 168,000 miles. I can provide repair orders, recall documentation, dealership communications, and other supporting records. I respectfully request that NHTSA document this complaint and investigate whether Stellantis/Ram is properly complying with applicable recall and extended-coverage requirements.

dealership for diagnosis. Service department has informed me that the root cause of this catastrophic failure was the crankshaft tone wheel. Furthermore, I was informed that this specific issue was an unaddressed/unfixed defect on my vehicle by Stellantis. What I learned is that the fix for a broken tone wheel required dropping the transmission to physically press a brand-new tone wheel onto the crankshaft. Because this was incredibly expensive and time-consuming, Chrysler rolled out a recall remedy consisting of a Powertrain Control Module (PCM) software flash.This should be unacceptable for trucks that cost $70,000 or any vehicle. Imagine that software failed what would have happened and yet we had no idea about this.

There is a known issue about exhaust manifolds for my year model truck. A ram technician said in 2019 mopar created a new exhaust manifold for my truck that would be less likely to create soot buildup and warping in the exhaust manifold. In 2021 my EGR was replaced because of a recall but now my exhaust manifold has failed and needs to be replaced out of pocket even though it's been a known issue and there was a remedy already made to alleviate the issue. Now because of soot buildup my throttle is limited until I have it fixed. But driving to a dealership is too far to be diagnosed as there has been cases of fires occurring when this issue occurs.

There is a recall for Ram 1500 manufactured between January 2015-September 2015 regarding failed power steering. My truck was manufactured February 2015 and was not on the list of specific Ram 1500s to have this recall done. I was with my kids getting an oil change on the truck. When I was leaving the maintenance bay my power steering suddenly failed and left us stranded to get towed. Chrysler stated that there was certain conditions that led for certain models to have recalls for this part, but not my truck. They could not give me a clear reason why mine was not included on the list.

In writing complaint against FCA for not fairness for some VINs with Ecodiesel doesn't include W68. Following with recall W58 vs W68, my VIN was picked for W58, but never pick for W68 because my VIN is not included. Just complete service for crankshaft throttle failure and spent $2000 for this. I am very disappointed that crankshaft failure recalled do not cover because W68 was not included. I think those W58 for computer update failed to prevent break down due to loose magnetic issue. My VIN is suppose to add recall for W68 because FCA missed this. W58 failed to cover the damages with crankshaft which is mean computer doesn't solve the problem.

This was one of the most terrifying experiences of my life. Losing engine power with a loaded trailer on a busy highway could easily have resulted in fatalities - not just for me and my animals, but for other drivers on the road. I was horrified and shaken, and I continue to suffer PTSD from the event. This is the second time the vehicle has broken down under dangerous circumstances. The failure was life-threatening, and it is obvious to me that the engine has now suffered catastrophic internal damage (likely a thrown rod). Recall Issues: I had already received a notice of Recall 22V-406, but when I contacted Chrysler, I was told the parts were not available and they would not buy back my truck. The repair was not released yet, leaving me to continue driving a vehicle I already knew had a serious defect. This delay put me, my animals, and the public at unacceptable risk.
