Parts supply issues. New vehicle production takes priority… Just because it’s hard to get parts doesn’t mean they can’t keep up with repairs. My son had to wait 3 weeks just for a heater hose for his RAM. Does that mean all the hoses are bad? Same for a rear shock, 1 month wait for that.
Heater hose, Get the f' out. The camshaft backorder has been going on since march, part suppliers are saying the first of the year, maybe. I had to purchase a cam thru a dealer and have it "expedited" thru Jeep cares, We will see where this goes. You believe what you want to believe.
Very, *very* few recalls are issued because of engine stalls. The 2.4L multi-air had excessive oil consumption that caused a stall for half a decade before they finally got around to making a recall for it, and even then most of them are expired by now.
Do you have any sense of what the defect rate is? Does .5% sound reasonable or is it worse or better? Is it fair to say that if the engine makes it 60k miles failure as described in the TSB is unusual? As far as recalls go if not forced by NHTSA it could be forced by company lawyers or a class action lawsuit. I don't know of the later which causes me to believe this problem is fairly contained.
I don't drive it like a performance vehicle, I didn't with my 2021 3.6 6mt either. I was responding to someone's question about if it was faster than the 3.6. I can say without question yes it is, but again that's not how I drive it or why I bought it.
That makes a lot of sense! I think the 3.6 is an awesome motor and I’ve seen some WILD things done to the 3.6. I think the folks who absolutely hate it are those who abuse their engine and then expect it to last. I have buddies like that. Those that refuse to change fluids and then get pissed when it’s smoking and the motor all of a sudden locks up cause it burned all the oil out of it. And yeah the 392 and LS are crazy prices. But I agree with you that folks hope their last 3.6 was junk and their newer one will be better!
I know I’ve seen videos of testing and the 3.6 is faster on 87 octane 0-60 but the 2.0 does better on 91 octane.
I'm pretty sure the 3.6L in a stock 2-door Sport without doors and top at sea-level is ~4 seconds faster than the 2.0T in a 4-door Rubicon X on 37s
I hear ya. I was 100% happy with my stock 1980 CJ-5 and had no issues until I just had to sell it and buy a JL. I swore I would never do that, but thought I'd be better off in my later years with some "modern" creature comforts like A/C, stereo, cruise control, and uh...doors. Never realized it would also come with a ton of "Jeep things" that make for a pretty disappointing owner experience. Good luck with your repair and please keep us posted!
2.4L Multi-airs had a near 100% defect rate. The concern came from how *much* oil was being burned. In a normal world the owner would've checked their oil once in awhile the issue would have never been noticed in any severity. Instead we had ~7500-10k oil change intervals and the engine was running low on oil around 5000 miles. Some would burn half a quart every 1000 miles and some nearly 1.5 quarts. Capacity of 5.5qrt, at 3qrts low it can exhibit stalls during forceful maneuvers. At 4 qrts low it'll stall just coming to a stop light. This is because it used oil pressure to actuate the intake valves in leu of a camshaft (hence the multi-air part). Without pressure the valves don't open and the engine stalls from lack of oxygen.
