So the 5.3L V-8 in the Saab 9-7x ( trailblazer ) went BOOM today.
Actually it went squeak, then silent.
We were in gridlock traffic leaving a baseball game. Truck was fine for a 3 hour ride there.
Next thing you know, the oil temp gauge falls off to nothing, and I get low oil pressure light on the dash. I'm stuck in gridlock traffic, moving zero mph.
Next thing you know, a few squeals and screeches later, the engine is totally seized.
Push truck off to the side of the road, lights out.
Truck has less than 50 K miles on it. Its totally old man owned and driven. He takes it to the dealership for oil changes. He may not be a car nut like we are, but the truck is NOT neglected and not driven hard ever. He changes the oil pretty regularly they put a 3000 mile interval on the sticker, he prob changes it every 4000 when he notices the sticker. The manual says 7500!!
So AFAIK the vortec 5.3 should be like bulletproof at this point right? I searched the interwebs, and I see nothing of sudden oil pump failures?
Is this common??
Tomorrow I start the warranty claims process, something I have not really done before on this scale. To be honest I was riding dads ass about the poor shift quality, I wanted him to get the tranny looked at before the warranty expired, but the engine failure is a complete surprise.
The entire reason I recommended this truck is because I thought it would be bulletproof and quite to my surprise, nothing could be further from the truth.
