P07E4
4 owner reports and 203 manufacturer filings across 117 model years from Acura, Alfa Romeo, Chrysler, Dodge and others.
Where P07E4 shows up
Source: NHTSA manufacturer communications and complaintsShowing the 60 model years where P07E4 appears most; it is on file for 117 in total.
A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.

What owners said

When we took it to be looked at by the dealership we were told that it was related to code P07E4
The failure terminated in codes P073D (unable to engage neutral), P07E4 (unable to engage gear 7), and P07E6 (unable to engage gear 8) which locked the powertrain
I know that my car is not tied to the recall regarding transmissions in the 2018-21 Navigators, Expeditions or Explorers, but the dealer gave me an error code of P07E4 which sounds VERY SIMILAR to this issue with these 2018-21 cars…

What P07E4 means
Source: SAE J2012 / OBD-IIP07E4 sits in the generic range of the OBD-II standard, so it means the same thing on every vehicle sold in the United States — but WhichTrim does not carry a definition for it and will not invent one. What is on this page is the record: who named it and on what.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P07E4
Source: NHTSA files and the OBD-II standardCan I keep driving with P07E4 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
