An owner complaint on a 2016 Jeep Grand Cherokee says the wipers started on their own and the check engine, stability control and anti-slip lights came on. The scan showed U0212 as lost communication with the SCM. It is one owner report. Check the module connectors and battery connections first. The source is owner reports, so this is labelled vehicle data rather than a confirmed fix.

U0402 fixed by a powertrain computer update on the 2021 Wrangler

Supported by vehicle data

FCA bulletin 18-012-23 covers the check engine light with U0402 and possibly other codes on the 2021 Wrangler, and updates the powertrain control module software. Ask a dealer about the update before replacing the transmission computer. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U0404 fixed by a transmission software update

Supported by vehicle data

Jeep bulletin 21-011-16 reprograms the transmission computer for the check engine light with U0404, invalid data from the gear shift module, on the 2016 Grand Cherokee and Durango. Drivers may also feel bumps on 2-1 downshifts while braking and see a blinking M on the shifter and cluster. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U0404 with lost power and flashing gear lights

Supported by vehicle data

Owners of the 2006 and 2007 Jeep Commander describe lost power when accelerating with boxes or lights around all the PRND gears and U0404 stored, and one dealer replaced the gear shift control module. The 2007 Grand Cherokee has similar reports. The source is owner reports to NHTSA, not a bulletin.

U0415 fixed by a transmission computer update on the 2025 Compass

Supported by vehicle data

FCA bulletin 21-043-25 covers the check engine light with U0415, invalid data received from the ABS module, on the 2025 Compass. The fix is a transmission control module software update, so ask a dealer about it before replacing parts. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U0418 set falsely by low battery voltage

Supported by vehicle data

Jeep bulletin 18-078-22 reprograms the engine computer on the 2021 Cherokee for U0418, implausible data from the brake module, and says the code can set falsely when battery voltage drops below 10 volts. Bulletin 18-023-19 also covers it on earlier Cherokees. Test the battery first, then ask a dealer about the update. We have not confirmed the bulletins are still current, so this is labelled vehicle data rather than confirmed by bulletin.

U0422 in the driver-assist modules on the Compass

Supported by vehicle data

Owners of the 2023 and 2024 Jeep Compass quote dealer readouts of U0422, implausible data from the body control module, in the adaptive cruise and blind-spot modules. Blind spot alert was unavailable and lane-keep faults returned after the codes were cleared, over several dealer visits. The source is owner reports to NHTSA, not a bulletin.

U0423 with the electronic shifter

Supported by vehicle data

FCA bulletin 9100641 lists U0423 among the loss-of-communication codes on the electronic shifter of some 2024 to 2026 Jeep and Wagoneer models. It says to check battery health, system voltage and the transmission control module before blaming the shifter module. Only the NHTSA summary was read, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U0423 with an A/C that stopped working

Supported by vehicle data

An owner complaint filed with NHTSA on a 2018 Compass reports U0423 (invalid data from the instrument panel cluster) stored after a dealer oil change, with the A/C no longer working. The owner links it to a recall for invalid cluster data. The source is an owner report that has not been independently verified. Check for open recalls first.

U0428 with the steering wheel locking

Supported by vehicle data

An owner of a 2014 Jeep Cherokee told NHTSA that the engine and traction lights came on and the steering wheel locked in position, with U0428 among several network codes stored. The vehicle note adds that a 2017 bulletin summary lists the code. Steering is safety critical, so have the vehicle inspected by a qualified shop. The source is a single owner report to NHTSA, not a confirmed diagnosis, so this is labelled vehicle data rather than confirmed by bulletin.

U1110 and U1120 with ABS and brake warnings and a blank speedometer

Supported by vehicle data

One owner of a 2019 Jeep Compass reports ABS, traction, brake and service transmission warnings with the speedometer blank. The scan showed U1110 and U1120, lost vehicle speed and wheel distance messages, with other network codes. ABS and brakes are safety systems, so have the car inspected by a qualified shop. The source is owner reports, a single complaint that NHTSA has not verified, so it is labelled vehicle data rather than confirmed.

U1110 and U1120 with ABS, traction and parking brake lights

Supported by vehicle data

An owner of a 2015 Wrangler reports the check engine, ABS, traction and parking brake lights with U1110 and U1120 among codes for lost wheel distance, vehicle speed and communication, found by two shop scans. Because the ABS is involved, have it inspected by a qualified technician. This comes from owner reports to NHTSA, not a bulletin, so it is labelled vehicle data rather than confirmed by bulletin.

U1110 and U1120 with a loss of power on the highway on the Cherokee

Supported by vehicle data

One owner of a 2014 Jeep Cherokee reports U1110 and U1120 appearing together with another network code, then losing power on the highway, pulling over and being towed to a dealer. Losing power on the road is a safety problem, so have the car inspected by a qualified shop. The source is owner reports, a single complaint that NHTSA has not verified, so it is labelled vehicle data rather than confirmed.

U1267 with the shifter locked in park

Supported by vehicle data

FCA 08-051-17 covers a shifter locked in park for 2.5 minutes at start-up with the service shifter lamp on, on 2016 to 2017 Grand Cherokee models. It lists U1267 as no valid data from the electronic shift module on the CAN network. The fix is a flash of the shift module, and the display is replaced if corrupted. Only the NHTSA summary was read. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U1267 with a service shifter message

Supported by vehicle data

One owner of a 2020 Jeep Wrangler reports a service shifter message with U1267 and an ESS indicator. The engine starts but the transmission will not shift out of park. This is a single complaint. The source is owner reports, not a confirmed repair.

U1424 as an implausible engine torque signal

Supported by vehicle data

FCA 18-035-16 Rev. A is a PCM reprogramming for a warning light with U1424, an implausible engine torque signal received, along with other codes. It was written for the 2015 Cherokee, and one owner saw the code return after recall flashes. Only the NHTSA summary was read. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U1428 fixed by PCM software on automatic models

Supported by vehicle data

FCA bulletin 18-091-19 lists U1428 with a torque request code on some 2018 Jeep Compass automatics, with the TCM in limp-home mode, and prescribes PCM reprogramming. Owners report a lock-up feel, stalls and limp-home. We read only the NHTSA summary. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

U1428 with lurching, power loss and a stall

Supported by vehicle data

Owner complaints on 2018 to 2019 Jeep Cherokee report U1428 with a camshaft position or other engine code, lurching, a Service Electronic Stability Control message, power loss and a stall in traffic. One mechanic readout describes it as a received engine torque request signal stuck. The source is owner reports, so it is labelled vehicle data rather than confirmed by bulletin.

U1428 with power loss at highway speed

Supported by vehicle data

A NHTSA complaint for a 2018 Renegade reports power loss at 55 mph with the check engine light and U1428. The car restarted and kept driving, and no repair was recorded. The source is owner reports, not a bulletin.

U3006 with a low 12V battery

Supported by vehicle data

Jeep bulletin 0810621 covers a low charge 12V battery on the 2021 Wrangler. It says to test, and possibly replace, the battery after a check engine light with one or more listed codes, including U3006. Test the battery and its charge first. We only read the NHTSA summary, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
