What's wrong?
The intake air grid heater on the 2007-2011 heavy trucks in this recall sits in the engine's air intake path. Its job is to warm incoming air before it reaches the diesel engine, which helps the engine start and run in cold conditions. On affected trucks with MBE900 EPA04 and EPA07 engines, that heater is part of the engine and cooling system.
The problem is inside the heater. Excessive internal temperature can cause the intake air grid heater to short circuit, which means electrical current travels through the wrong path instead of through the heater element as designed. When that happens, the heater can fail and no longer do its job in the intake system.
There is no warning sign before failure. An owner is not told to watch for a sound, smell, warning light, or change in how the truck drives before the heater shorts and stops working.
