U023A: questions drivers ask
What does code U023A mean?
U023A sits in the generic network range (network: communication between the car's control modules), but its SAE definition is not in CarHooq's list, so CarHooq shows only what owners reported. 3 owners reported it to NHTSA, most often for the Ford F-150 (2), Ford Escape (1); their reports describe what happened.
Which cars get code U023A most often?
In NHTSA owner complaints, U023A is mentioned most for the Ford F-150 (2), Ford Escape (1), across 2 models and model years 2020 to 2024. Popular models collect more reports because more of them are on the road.
Is there a recall for code U023A?
No NHTSA recall text names U023A directly. 3 recalls on the cars that report this code concern the same component owners name most (Power Train); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows U023A?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
How this page was made
CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of U023A. The code is in a generic range but its standard definition is not in CarHooq's list, so CarHooq shows only what owners reported. Nothing here is a diagnosis. More answers: the fault code FAQ. Data: NHTSA Office of Defects Investigation (public domain), retrieved November 9, 2026. How CarHooq reports are made.
