Four days after Onward Manufacturing of Canada announced a recall of three models of gas grills after the firebox of two samples melted in tests conducted by Consumer Reports, the U.S. Consumer Product Safety Commission followed suit today with its own recall. In the recall notice, the CPSC said the recall involved 4,800 Signet, Sovereign and Sovereign XL series gas grills.

Consumer Reports encountered the problem in a routine test to determine how well a grill handles flare ups from fatty foods. In the tests, a Broil King Signet 90's firebox melted, dripping molten metal onto the area beneath the grill. We subsequently tested two other samples of this grill: The firebox of one melted and that of the other grill had begun to crack and deform by the end of the test. Because we believe that the Broil King Signet 90 is dangerous and poses a serious safety risk, we judged it Not Acceptable.

Our earlier report on the recall details our testing, includes a video, and outlines the steps that Onward is taking to correct the problem.
