4/19/21–THOR Ind. engages Exponent Engineering to conduct analysis of regulators to determine source of oily substance.

 

5/10/21–Safety Committee Meetings conducted at KZ RV, Keystone RV and Jayco RV, to update them on regulator investigation. All committees request further investigation of specific claims and confirmation of Exponent findings.

NHTSA was informed that more confirmation testing was required to definitively establish a population.

 

7/7/21 – Exponent provided Thor Industries draft testing results of the interaction of the second stage seal with various plasticizers found in hoses used on the regulators from the last five years of manufacturing. Only one sample per year was available to test. This testing confirmed similarities in several years.

 

7/8/21 – Exponent’s draft testing results reviewed with Thor Industries companies. Due to small sample size, it was requested to see if more samples could be secured for confirmation testing.

 

7/16/21 – Thor Industries conducts meeting with Dehco, UFP and Winnspec to discuss the regulator recalls.  Winnspec agrees to provide further second stage seal discs to confirm earlier testing.
