"the first vehicle to employ dual LED-based daytime running lights"? I've seen several current production cars with this, including my Toyota Venza. My wife calls it scary and ominous when I drive into the driveway in the evening.
While I am able to purchase this vehicle, I would never spend the money to keep it up. I would rather have fewer components, well styled simpler design, and good performance.
Off the show room floor I want to use LED's for a reason, not for effect. The aftermarket people are really good at deploying them for effect as options. Personally I do not want to drive more components with the attendant higher operating cost. How much more do we think the repair bill for a front end collision will run just because of the do-dads? Further, I suspect this car continues in the vein of mediocre American suspension tuning as well, so I cannot see the value.
I would rather drive an '88 LTD Crown Vic on the cheap with mediocre to poor handling, rather than consume capital needlessly on gaudy and unnecessary expense. In fact I do, so I guess Detroit has good reason to dismiss my viewpoint out-of-hand.
I recently attended a training where the 3rd brake light issues on the older Cadillac's was discussed. When GM introduced the LED 3rd brake light, they were very early adopters of the technology. They did due diligence reliability testing, but their design still failed in the field. They ended up running a HALT test and found the source of the issue. It was not the LEDs as components that fail, it was the wires that interconnected the LEDs.
By being early adopters of LED lighting in automotive applications, GM is ahead of the iterative learning curve. I would not hesitate to buy a GM product with lighting like this. I would, avoid most other automakers like Audi who have recently added LED accent lights.
And this is not an issue of LED reliability... the LEDs as components are extremely reliable. The issue is the circuit board design, solder connections, interconnect wires, LED cooling methods, ETC... It seems that engineers think, 'Gee, LEDs last a long time. Let's slap some on a PCB and throw it behind some glass and it will last forever.'
A fantastically reliable LED is useless in an open circuit.
We have a mandatory annual vehicle inspection and if, during that inspection, one LED is found burned out or not functioning, the car fails! Replacing a single LED is beyond most small garages and for the most part, single LEDs are NOT available at the dealer. Thus one burned out LED can end up costing you several hundred $$. Yes, LEDs are, by design, capable of lasting 20,000 hours, but unfortunately LEDs are connected to other 'stuff' which has the shelf life of bread! This is not progress.
