Quick answer

Altec has learned that on certain AT37ME/PE/SE, AT41ME/PE/SE, and AT48ME/PE/SE units built from August 2021 to June 2022 due to a missing valve driver calibration, the estimated output current for certain functions may exceed the digital fuse setting resulting in the unit stopping operation in cold temperatures. This may occur several times until the coil warms or until the ambient temperatures rise above a threshold. The customer should request a firmware update to remedy the issue.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
