P0A43 fault code: what 27 Chrysler owners reported

…Problem code is P0A43-00. This is the SECOND transmission failure since ownership. I've had the vehicle serviced only at the dealer where purchased. The dealership confirmed the FIRST incident with the same problem code was diagnosed on 1/30/24. The transmission was replaced at this time. The van had 12,134 miles. The 2024 incident also was triggered at highway speeds. If my memory is correct, I believe I reported the first incident to the nthsb at the time.

Vehicle suffered sudden loss of motive power due to Diagnostic Trouble Code P0A43 (Drive Motor A Position Sensor Circuit Intermittent). The failure is caused by thermal and chemical degradation of the internal transmission wiring harness, resulting in an internal electrical short submerged in transmission fluid. The vehicle is able to be powered on again and driving can be continued however certain speeds trigger the issue. The check engine light appears and remains for a short period. The vehicle was purchased through CarMax of Naperville, IL [XXX]. The vehicle began to experience the defined issue the last week of May 2026. The vehicle was brought to CarMax [XXX]. CarMax transferred the…

…In an email I was told: "what was found was a stored fault code P0A43-00 Drive motor "A" position sensor circuit intermittent. There is a TSB 21-037-26 for that fault code and vehicle going into limp mode and the repair is a rebuild kit for the transmission. " Despite this they also said in an email: "cleared codes and perform test drive. Code never came back and it states in the procedure you must verify the problem meaning it happened or is happening via active fault code which it is not." They refuse to fix the problem, despite acknowledging it happened. I was told to take the vehicle back and drive it as normal until it happens again, which I refused due to safety concerns. The vehicle…

…On the way home, I stopped at both an Advance Auto and an Autozone where both read the only code present as P0A43, see attachment. I also noted that the Emission Ready status was showing "NO". I then drove the vehicle less than a mile to our home where it has remained in my driveway. Mileage is now 24972 on the odometer. I plugged in and charged the vehicle to 100% high voltage battery state. Two days later on XXX, I started the vehicle and the MIL is no longer illuminated, still at 24972 odometer. The dealer promised me that the code would remain and could be read later, but it did not and nobody erased it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C…

This vehicle has experienced three separate powertrain failures stemming from the same transmission defect (DTC P0A43 — Drive Motor Position Sensor, eFlite transmission). Incident 1 — April 19, 2026: Complete sudden loss of motive power on the highway with family aboard. Vehicle towed to Castle Rock Chrysler CDJR. Failed Repair — May 8, 2026: Chrysler corporate mandated a software flash rather than a hardware repair. Vehicle failed identically within 10 miles of pickup in live highway traffic. Towed back same day. Incident 3 — June 6, 2026: A replacement transmission was installed. Within one week of pickup, a progressive transmission whine developed followed by visible smoke from the engine…

…(Woburn, MA), authorized Chrysler dealer, confirmed fault codes PA121-00 and P0A43-00 on 8/4/25 and replaced the PIM.

My vehicle has been saying engine will shut off soon, and loses power . Transmission is the issue as I have had it diagnosed 3 times with the code P0a43. Mazda dealership which I purchased the vehicle verified by running a diagnostic.engine light comes on after the vehicle shuts off. Me and my children’s safety is at risk due to it stopping multiple times on freeway also stopping at a stoplight that was around a curve with blind spot . Has stopped on a two lane road with no emergency lane. Stopped at another light and had to wave traffic around.

This submission supplements my prior NHTSA ODI complaint regarding the same vehicle and loss-of-motive-power condition. On Nov 8, 2025, the vehicle experienced a loss of propulsion at highway speed, creating an immediate safety risk. The vehicle could not maintain speed and required evasive action with no propulsion to avoid traffic hazards. Following the incident, the vehicle was inspected and stored diagnostic trouble codes P0A3F-00 and P0A43-00 were retrieved, relating to drive motor position sensor / resolver signal loss or degradation. These fault codes are associated with loss of propulsion and indicate a propulsion control signal-path fault, rather than a condition resolved by…

Vehicle went into limp mode three times while driving on the highway, forcing us to pull over to the shoulder. Luckily there was a safe place to pull over but created a major safety concern. It triggered code P0A43-00. The dealer initially couldn't recreate the code on 12/18/25 at which point they cleared the code and returned the car to us. It happened again on 12/30/25 at which point the dealer followed Chrysler instructions to conduct pin drag test but no problem was found. Dealer drove 60 mile test and didn't recreate the fault and returned car to us. The same issue again occurred on 1/9/26 at which point Chrysler authorized invasive transmission repairs. This issue directly aligns with…

…I have screen shots of them from my personal OBDII reader: P0A43 "Drive Motor 'A' Position Sensor Circuit Intermittent", C2225 "Status: MIL - PCM Disabled EDU: No Sub Type Information". After doing my own reading, it seemed many others have experienced the exact same symptoms and it has required a transmission repair/replace. I also learned most people had a battery charge on the high voltage battery (as this is a plug-in hybrid) when the vehicle shuts down. I charged my van, took it for a ride at 75MPH and it occurred within the first mile. I took it back to the dealership, and at this point, I refuse to drive it until the hardware fix happens. It seems like this should be a recall for all…
