Mention Proton, and more often than not the “power window issue” will crop up from both detractors and those who have experienced it themselves. Proton MD Datuk Seri Syed Zainal Abidin admits that he has been obsessed with the power window issue since he came in five years ago.

The man points out that Proton has long turned the corner in this, and current gen cars are no longer bugged with power window problems. Generally, Defects Per Unit (DPU) has dropped to 0.26 in August 2011 from 8.0 in 2006/07.

But one can only do so much to convince 28 million people, as Syed Zainal said, so Proton has come up with the Power Window Promise to put this issue to rest. The main component in this promise is the Power Window Lifetime Warranty. A very unique warranty for a very unique situation in a very unique market!

Here are the terms. The Power Window Lifetime Warranty (PWLW) is applicable for all new Proton models registered from 1 September 2011 onwards. The warranty is for 10 years from the date of registration, or 250,000 km, which Proton takes as “the lifetime” of a vehicle. Also included in this scheme are current Proton cars that were still under manufacturer’s warranty as at 1 Sept 2011.

For instance, if a Proton Waja is two years and 10 months into its three-year factory warranty at 1 Sept 2011, it will be eligible for PWLW. The 10 years will be counted from the car’s date of registration, and if it has already done 100,000 km, the warranty will last for 150k km more, whichever comes first. But the said Waja won’t be eligible if it has been serviced outside of Proton’s service network at any time in its life.

The same goes for new cars. To be eligible for the warranty, cars must be serviced at an official Proton service centre throughout the duration. I also found out that from now, cars brought in to Proton SCs for regular service will also undergo some “power window servicing” which involves silicone spray to reduce friction, among other measures. Previously optional, there’s no extra charge for this, and is part of Proton’s efforts to improve itself.

Applicable to both private and fleet owners, PWLW covers four main components in the power window mechanism, namely the PW regulator, PW motor, PW switches and PW run channel. If your case complies with the T&Cs, Proton will absorb all labour and parts costs. There’s no limit on how many claims can be made per car.

Eligible cars that are in the “still under warranty” category explained above need to claim their Power Window System Warranty Registration certificate from any Proton service centre. Take note that prior appointment must be made. This process is not necessary for Proton cars registered from 1 September 2011, since the Power Window Promise is already included in your car’s service booklet.

“Correcting this perception is a challenging but necessary task, and PWLW is one of the initiatives that is being undertaken to put to rest this particular stigma. It saddens us that our customers purchase Proton cars whilst questioning the quality of our power windows, to the point that they refuse to use it for fear of damaging it,” said Syed Zainal, recalling a story we shared with you before.

“Our message is simple: Should you buy a Proton car today, please know that the power windows are working, they are working well and you have our Power Window Promise to back you up,” the boss confidently added.
