Water can seep into a wiring harness and cut the power steering on 265,512 Ram ProMaster vans

Chrysler, the maker that sells Ram, is recalling 265,512 ProMaster vans because water can get into the electric power steering wiring harness and switch off the assist that makes the wheel easy to turn. The vans are model years 2022 through 2026, including the battery-electric ProMaster built from 2024. A driver who loses assist is left steering a loaded commercial van by muscle alone.

The filing puts the van count at 265,512 under a single campaign, and it separates a smaller group of loose parts: 8,378 replacement harnesses sold over the parts counter under their own equipment recall.

Where the water gets in

Chrysler’s report to the National Highway Traffic Safety Administration, filed Sept. 29, 2026 as campaign 26V621000 and carried internally as recall 92D, says: “Water may enter the electric power steering wiring harness, which can disable power steering assist.” NHTSA classes the component as the electric power assist steering system, and its stated consequence is that a loss of power steering assist can increase the risk of a crash. The owner letter filed with the agency repeats the same defect language and adds that the VIN lookup opened on Oct. 6, 2026.

The physical route is described in more detail by Mopar Insiders, which reported that water reaches the steering system’s electrical connectors and the steering gear itself, where it corrodes the wiring harness. The affected parts are body and jumper harnesses, supplied from Spain by Lear and from Mexico by Flex, according to that report. Corrosion of that kind is gradual, which fits the description of assist that can cut in and out before it stops altogether.

Which ProMasters, and how many of each

The record is slightly untidy about models. NHTSA’s vehicle entries list ProMaster and ProMaster BEV by year, while Chrysler’s problem description names the ProMaster 1500, 2500 and 3500 and the 2024 to 2026 Ram 3500 Electric. Mopar Insiders breaks the 265,512 into 44,391 ProMaster 1500 vans, 147,204 ProMaster 2500, 72,043 ProMaster 3500 and 1,874 of the 3500 EV, and those four figures do sum to the campaign total. The 2500 is more than half of the whole recall.

These are vans, not pickups. Every vehicle entry in the campaign is a ProMaster or ProMaster BEV, so the 1500, 2500 and 3500 designations in the problem description read as ProMaster weight classes, and no Ram pickup appears in the model list.

Chrysler estimates that 7.7% of the recalled vans actually have the defect, Mopar Insiders reported, but every one of them needs inspection because the company cannot tell from outside which harnesses are affected. The company said it knew of one accident and no injuries that may be related, across all markets, and the same report says there is no warning before assist goes: the power steering light may come on only once assist has been lost.

A repair that is not ready, and a parts recall beside it

The sequence of dates shows how long an owner may wait. Chrysler reported the defect on Sept. 29, the owner letter and the VIN search went live on Oct. 6, interim letters follow on Nov. 17, and the dealer notice cited by Mopar Insiders points to a repair in the fourth quarter. For a delivery or trades fleet running several ProMasters, that is a window of weeks in which vans stay in service on the strength of an inspection that has no part ready to follow it. The record offers no interim driving restriction.

The remedy in the NHTSA record is that dealers will inspect and replace the wiring harness and the electronic power steering gear as needed, free of charge. The replacement harnesses have improved sealing. A dealer notice cited by Mopar Insiders put the start of the repair in the fourth quarter of 2026, so the fix lagged the filing. Interim letters are expected to be mailed on Nov. 17, 2026, with a second letter once the final remedy is available. Customer service is at 800-853-1403, recall number 92D.

The companion filing is equipment recall 26E067000, which covers 8,378 Mopar body and jumper wiring harnesses, including the electric power steering harness, sold as replacement parts. The same defect applies: water can enter and disable assist. Chrysler will inspect and replace the harness and gear as needed, and uninstalled harnesses will be repurchased. Anyone who bought a Mopar harness for a ProMaster repair in recent years should treat that part as a separate item from the van recall.

NHTSA’s open dataset shows both filings among the reports received between Sept. 29 and Oct. 7, in the weekly recall data. Owners checking a specific van can use NHTSA’s VIN lookup, which Mopar Insiders advises doing by VIN and not by model year, since a given van may or may not sit inside the affected build range.
