Engine Failure

[TruckeeTaurus]

Our Lexus RX350's engine just blew up with only 77k miles. Religious oil changes done every 5k miles. Mechanic said he's seen 2 of the same thing happen to the 3.5V6 2GR engines. So yeah, Toyota/Lexus is not impervious. But GM V8's are having a bad time right now. Wouldn't touch one at the moment.

Meanwhile my 2008 RX350 will outlast me and become an heirloom.

I hope GM has gotten the bugs worked out for us that own the 5BW. Seems like they should now that they’ve had a few years to see the problems that have been occurring, and how much it is costing them to cover warranty issues. I paid an extra 1k to extend it to 10yr/100k bumper to bumper.

Porsche had issues with the M96 and M97 engine used in multiple years of 911s and Caymans that could result in catastrophic engine failure (google IMS Bearing). Although the aftermarket came up with some solutions, Porsche simply redesigned the engine on newer models to eliminate said bearing. They made no effort to rectify the older cars. I'm guessing but the failure rate is probably comparable - Rennlist has many similar back and forth threads about how IMS is either end of the world or a total nothing burger. Consensus us a ~2% failure rate. If Porsche did nothing, I wouldn't be getting my hopes up that GM is going to do anything either.

True, now even in the 992 GT3 and GT3RS.....there is an issue of the small steel puck, that sets the valve clearance, that sits on top of the vale stem popping off...getting into the oil system and grenading the engine. On the 991 GT3 and RS, the DLC coating coming off the cams and also destroying the engine. Then add in bore scoring to the M97 and the 91A1 engines as well The V8 Panamera S also had cam issues where the little thingy that held the cams to the cam's gears, popping off......ruining the engine.

When I worked in the Porsche shop as a technician we had a boxster with that engine come in for an oil change and as it was driving into the shop, the bearing went. Porsche ended up goodwilling the engine and the customer only had to pay for labor. Not bad considering it was a couple years out of warranty.

This makes me very glad I paid the extra 1k to make the bumper to bumper 10/100k!
