I wonder what Holden would do if some vehicle with a 7 year warranty suffered such a fault at one year old. Would they provide a recoed box with a six year warranty? I'd want the box warranted for 7 years in such a case
The business I work with sells heavy duty construction equipment, i.e. yellow goods such as wheel loaders, excavators, articulated dump trucks etc as well as on road and off road prime movers.
Any defect rectification work undertaken during the warranty period is warranted for the
remainder of the original warranty period.
This also applies to spare parts purchased by a customer that have a defect and are replaced under their applicable warranty.
So applying this principal to your scenario, the box replaced at the end of year 1 would be warranted for the next 6 years, being to expiry of the original 7 year warranty period. If it cacked itself at say year 3, the replacement under warranty would be warranted for the remaining 4 years. Cacked itself at say 6 yrs and 11 months, then you would get 1 month warranty from the manufacturer.
This can obviously be blurred late in the 7 year warranty period when the manufacturer (or their dealer) is outsourcing the warranty work as is the case with the Holden box with the sub-contractor providing their own separate warranty, in this case 2 yrs.
Of course this doesn't stop purchasers trying to contract us into warranty rectification work for a period equivalent to the original warranty period, but starting from the completion of the rectification work. Again using your scenario as an example, this would mean the customer has a defect rectified at say year 6 and expects another 7 years warranty on that rectification. This is what we call warranty on warranty which simply won't fly.
In my experience, many other goods apply the same principal.
Best to check the wording of Holden's warranty doc to see if it contemplates this scenario. If not, contact HCC on live chat and get their response in writing.
