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!

@TruckeeTaurus You paid $1000? I'm, checking on extending a warranty on a low mileage 2023 and the first Cadillac dealer I talked to about buying/adding the extended warranty (not 3rd party!) quoted me $3800 for a powertrain 8yr/120k mile warranty to a platinum/everything 10yr/120k mile for $6k. This is from date of purchase of warranty (I'm skeptical if that is actually the case on date!). I'm love to hear from those that bought extended warranties, especially from those that added a warranty after initial purchase!)

Thanks!

Yeah, I paid cash for my ‘25 CT5 BW, and for some reason still sent me to financing. We chopped it up for a while, I told him I didn’t want any of the extra shit he was trying to sell… he offered to extend the warranty to 10/100 b2b for 5k, and I laughed. He asked what would make it worth it for me, and I told him if it were for a grand I’d do it. It worked.

Try MacMulkin Chevy in Nashua NH..more specifically Todd Sutherland.

One could possibly infer from this that the markup on these warranties is crazy high. Good for you, knowing how to negotiate.

I purchased 100,000-mile B2B warranties with no time limit on my '21 Corvette and '21 GMC Sierra 1500. The deductible is $100. Both were purchased with the vehicle and cost around $3K.

@TruckeeTaurus ...I agree, $1000 is stupid cheap. I can't believe you got it that cheap. Was it GMPP or third party?

I bought mine from Todd at MacMulkin. Great guy to do business with. $100 deductible, 96 month/80,000 from in service date, paid around $2200

That is easily the best warranty coverage for price paid I have ever read about on any car by any buyer. Incredible work, TT! It will certainly more than pay for itself.

 

[beamon]

I think he paid a few thousand over msrp so maybe the dealer recognized that with their kind heart.

Pretty sure it’s GMPP. It doesn’t show up on my app though, only in the paper work, so maybe it’s not?

 

[TruckeeTaurus]

Word… I did pay 2000 over MSRP I think.

They wanted 10, I told the sales guy to see what he could do for me because there was one at the dealership by my house for 7k less. I said that with the 17k I’d save not buying that one, I could get the cheaper one painted the color I want!

He came back the next day that he’d talked em down to 4K over, and I countered with splitting the difference. I just really hit it off with the sales guy and he made it happen for me.
