Nothing came of the LB7 injectors problem except extending the warranty and part redesign, I doubt anything comes of this other than that.

You never know. Back then social media and capability of information sharing was in its infantry. Now, a brand reputation hangs in the balance of public perception. Depending on how this is played it could mean interesting things for the company. Iíll be curious to see what happens.

I have one with 590,000 on stock cp4. I always make it a point to let the truck warm up before a drive it.

They should do a recall and change the pump.

More likely they will add it as a warranty for some specific mileage.

It would be nice to know the numbers. Out of all the LML's made, how many failures?

Since 2011 when LML came out, my dealership has repaired approximately 10 with grenaded pumps. I’ve also replaced 2 that did not grenade, just couldn’t put out the pressure. Keep in mind, we only hear of broken ones on this forum, yes it is more common than a CP3 pump failure, but still not THAT common.

interesting perspective, would be interested to know the actual percent that have failed.
