Service campaign 26TC01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

An electrical connection for the rear window defogger may not have been installed correctly during vehicle assembly. Overtime, this can cause the rear window defogger to become inoperable, which could reduce visibility through the rear window when moisture or condensation is present

The document
