U0164: questions drivers ask

What does code U0164 mean?

U0164 is a generic OBD-II network code. Its standard definition is "Lost Communication With HVAC Control Module". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 6 car models.

Which cars get code U0164 most often?

In NHTSA owner complaints, U0164 is mentioned most for the Jeep Cherokee (2), Chevrolet Cruze (1), Chevrolet Cruze Limited (1), across 6 models and model years 2015 to 2020. Popular models collect more reports because more of them are on the road.

Is there a recall for code U0164?

No NHTSA recall text names U0164 directly. 5 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 U0164?

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 U0164. The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis.
