2016 RAM 5500

The Office of Defects Investigation (ODI) has received 14 Vehicle Owner Questionnaire (VOQ) reports and 6 EWR Death & Injury (D&I) reports describing post recall remedy failures of the brake transmission shift interlock (BTSI) system in certain Model Year (MY) 2013-2018 RAM pickup trucks.The subject vehicle models include 1500, 2500, 3500, 4500, and 5500 trucks equipped with a column mounted shift lever.The failures of the BTSI described in the VOQs occurred on vehicles that had all previously been repaired under recall 17V-821 or 18V-100.Both recalls address a potential condition which can cause the BTSI locking pin to become stuck allowing the transmission to be shifted out of Park without depressing the brake pedal and/or without having a key in the ignition.Shifting the transmission out of Park when not having the brake pedal depressed can result in a vehicle rollaway. ODI is opening this Recall Query (RQ) to review the effectiveness of the 17V-821 and 18V-100 recall remedies, understand the root cause of additional vehicle rollaway incidents, and identify any other possible root cause that may affect the performance of the BTSI system.

On December 12, 2019, NHTSA's Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE) 19-017 after receiving three Vehicle Owner Questionnaire (VOQ) reports alleging failures of the front driveshaft and/or transfer case, resulting in conditions of 1) a loss of engine power, 2) loss of steering assist, 3) loss of foundation brakes, 4) unintended air bag deployment and 5) engine/cab fires from combustible fluids striking hot exhaust components. The VOQs involved model year (MY) 2015 through 2017 RAM 4500 and 5500 vehicles. ODI received information from the vehicle manufacturer [Fiat Chrysler Automobiles (FCA)] via information request letters dated February 28, 2020, and April 21,2020. Supplemental information was received on March 17, 2021. A review of the responsive manufacturer information, and related meetings and presentations, showed that the transfer case failures in 97.5% of the claims did not disable the vehicle. Since analysis showed that a failed driveshaft could result in catastrophic damage to the transfer case as well as other safety risks (i.e. steering/brake failures etc.), ODI shifted the investigation to focus only on the front driveshaft failures. The double cardan universal joint design requires maintenance lubrication within every 8000 miles. Despite an under-hood maintenance reminder label and professional servicing at both dealers and independent repair facilities, the driveshafts were often found to be unlubricated due to lack of awareness, difficulty of the operation or the lack of the special tools needed to perform the work. To increase the maintenance lubrication rates, in the summer of 2021, FCA launched a communications campaign, circulating awareness bulletins, training information, special tool options and instructional videos through more than a dozen channels covering both dealer and independent repair facilities. Additionally, in the fall of 2021, FCA mailed a VIN-specific letter to each registered owner reminding them of the maintenance needs, and also sent a special grease gun adapter to every FCA US dealer and fleet operator with an FCA US dealer code. Since January 2022,NHTSA has not received a complaint of front driveshaft failure due to lack of lubrication that can lead to failure conditions such as loss of engine power, loss of steering assist, loss of foundation brakes, unintended air bag deployment and engine/cab fires. This drop in complaints, the communications campaign launched by the manufacturer, and the absence of reports from the manufacturer, support the closing of this Preliminary Evaluation. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

The contact owns a 2016 Ram 5500. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from underneath the vehicle. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the transfer case. The contact stated that the transmission was loud and vibrated abnormally while driving. The contact previously owned a 2014 Ram 5500 with a noisy transfer case which caused the vehicle to vibrate abnormally, and due to the failure, the contact was given a newer model vehicle. The contact stated that the current vehicle was not repaired and remained with the dealer. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 156. The VIN was invalid.

We have sent this in for recall repairs and Dodge either did not have the parts or said it would be weeks before they got the parts and we, as a company have had three dodge ram 5500's in the last week that have broken all the wheel studs off, snapped a single stud, or the the lug nuts have gotten loose even after torquing them to the newly recommended 129ft/lbs. We have 30 plus of these trucks and we are worried that if dodge does not get this fixed that there will be an injury.

The contact owns a 2016 Ram 5500. The contact stated that while driving at approximately 15 MPH the driver's side rear outer wheel suddenly detached from the vehicle. Upon inspection, it was discovered that all ten lug nuts securing the wheel had sheared off causing the failure to occur. The vehicle was taken to the local dealer who serviced the vehicle under the NHTSA recall campaign number: 21V398000(Wheels). The lug nuts were replaced and the recall was completed. Approximately 3 months later the same failure occurred on the front driver's side wheel. The contact stated that while driving 70 MPH the wheel suddenly detached from the vehicle causing the driver to lose control of the steering and crash into a concrete barrier. Upon inspection, it was discovered that the 10 lug nut bolts had also sheared off causing the wheel to detach from the vehicle. During the crash the front driver, front passenger, and rear passenger side occupant all sustained neck and back injuries that later required medical treatment. A police report was taken at the scene and the vehicle was later towed back to the local dealer. The vehicle was not repaired under the previous recall campaign. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 120,000.
