Recently I was informed about a possible engine failure involving a "Grid Heater Bolt". Upon my query, I learned the following: The RAM grid heater bolt failure can lead to serious engine damage. Here are some key points: 1. The grid heater nut can melt and fall off inside the intake plenum, often due to the grid heater relay sticking "on". Or fall off due to vibration. 2. A bolt in the 2007-2023 RAM 6.7L intake air heater can cause severe engine damage, and a warning code (P2609) may indicate this issue. 3. The grid heater bolt/nut can wear from heat or vibration, potentially dropping into the cylinder and destroying the engine. The risk related to this can be minor to catastrophic. Any potential engine failure during operation could cause damage, fire, injury or death. Upon researching this issue, I found the Internet full of warnings, but yet since 2007 to 2023 no factory solution or recall has been made. A recall has been made for simuliar issue. See attached. As a preventive measure, I am replacing mine with a aftermarket device. Something Ram or Cummins engine should have done since 2007. I have not been in a collision or a engine failure. But I am sure since 2007, someone has. There are two or three aftermarket repairs that the manufacturer should have resolved.

While test driving a 2017 RAM 3500 6.7L Cummins diesel at Cherry Hill Dodge Chrysler Jeep Ram in Cherry Hill, New Jersey, both the check engine light and the regen warning light came on simultaneously. I returned to the dealership, looked up the regen warning, then retrieved my BlueDriver OBD2 scanner from my own vehicle. I scanned the truck on-site and ran live data. The scan confirmed the diesel particulate filter (DPF) was 100% full, and the regeneration system was not functioning. Permanent fault code P242F was stored, and the exhaust backpressure reading was over 25 PSI at idle — indicating a severely blocked system. These faults were not disclosed by the dealership, and no inspection or documentation from a diesel technician was available. I later discovered the truck also has an open safety recall (Manufacturer Recall Number: C4B / the federal safety agency Recall Number: 24V‑896) for a potential failure of the Brake Hydraulic Control Unit (HCU). This recall involves the loss of ABS, Electronic Stability Control, and Traction Control, and the recall status is listed as incomplete with no remedy available as of the test date. I offered to purchase the truck for $35,000 out-the-door on the condition that the emissions system was repaired and certified. The salesperson spoke with the manager, then returned and told me the vehicle was no longer for sale. I then overheard the manager say they planned to wholesale the vehicle, likely without disclosing these active safety and emissions system failures. I am filing this report to ensure the vehicle is flagged for unresolved safety and emissions violations before it is sold or auctioned in its current condition. I have full diagnostic scan data, photographs, and written communication from the visit available upon request.

P2609 check engine code for a component in the diesel fuel intake chamber. The relay failed, melted a bolt and attached nut that fell into the intake manifold. The part then traveled into piston cylinder destroying the valves and the engine. The truck then is powerless on the roadway. This is a known issue for all Ram diesel’s manufactured 2007-2024. This should be a major recall and Ram has done nothing for vehicles out of warranty. Please help.

In my case engine warning light came on before the bolt dropped into cylinder and was repaired before damage occurred. Also see the following Utube link for video on issue.
