2018 Ram 3500: shudder or vibration when accelerating

Filed Jul 18, 2023 · Steering, Wheels · PA · crash

I was driving on the interstate highway. While driving at 60 mph towing a fifth wheel RV the front end shuddered for several seconds. Then the drivers side front wheel assembly broke off at the wheel studs. I was able to safely get to the breakdown lane. The drivers side front wheel assembly struck another vehicle traveling the oncoming lane. I was told that the vehicle that was struck was totaled. The police on scene documented the incident. The insurance representative has been notified and approved the repair. The collision repair facility documented. I also have pictures indicating broken front wheel studs.

Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

The Bosch CP4 fuel pump internally disintegrated sending metal shavings throughout the fuel system. On the highway accelerating out of a toll both without warning, the truck lost almost all acceleration power and began to shudder. There weren't any preexisting warning lamps or messages. Any time after that when accelerating up to highway speeds quickly or attempting to maintain highway speeds the truck would lose acceleration and begin to shudder. When I took it to a mechanic, they informed me the CP4 fuel pump had "grenaded" and the whole fuel system needed to be replaced. If this had happened when merging into traffic or crossing at an intersection, I could have been hit because I couldn't accelerate as needed. The manufacturer (Ram) is aware of the malfunction and has issued recalls for the 2019 and 2020 years, but not 2018s which have the same exact part. The repairs have been completed on the truck and I have copies of the invoice.

When hitting bumps or uneven pavement at speeds above 50 MPH the truck will sometimes start shuddering and vibrating violently almost causing total loss of control. The only way to stop it is to come to a complete stop. It does not do it on all bumps or rough roads. It seems to be more frequent when hitting a bump in a curve or hitting a bump with first one wheel then the opposite wheel hits one. It does this loaded or unloaded and has done it while pulling a 16000 pound fifth wheel rv. The truck only has 16000 miles on it and has done it about 10 times since it was purchased. I have had it in the shop and was told they could not find any problem. I have it back in the shop at a different dealership and have started a ticket with chrysler. So far they have done nothing.
