For these exact reasons I have only gone to the dealer for my 5th gen oil changes except on 3 occasions. Them being Toyota and the seller of my vehicle builds in some accountability. So if they screw it up they will fix it. Jiffy Lube not so much.
So yesterday I braved a Jiffy lube experience for 3rd time on my 5th gen. I told the guy specifically. I wont go to your Murray Road location after they sent me out missing 2 bolts and left the drain hatch open, literally hanging by one bolt. Caught that once I made it home and inspected in my driveway.
So after telling the guy this and him saying inexperienced techs forget things. They sent me out with the same bullshit. This time I went right next door to Fred Meyer on Cornealius Pass/HWY26 and inspected and put a wrench on everything. Yep stripped skid bolt and drain hatch open hanging by one bolt. Mind you yesterday morning it was dead, I was the only rig there- so the rush excuse is out. Guy apologized a bunch, but what do you really say when presented with the failed results of the last Jiffy Lube experience only then to repeat it again.
So today I took off both skids tapped the stripped nut, but no dice, it's wasted. While under there I notice my front diff 10mm drain plug looks stripped. Yep put a wrench on it and the bite is shallow as the allen key wont fully seat. Diffs only changed once by dealer and lastly 30k ago at a Jiffy Lube. So another Jiffy lube created problem that needs to be fixed.
Moral of the story, Jiffy Lube hires from the bottom of the barrel. Toyota at least is accountable for the work they do.
I knew I was taking a risk by going to Jiffy Lube, but the idea of sitting at the dealer for 2+ hours was unappealing. So there you go kids I knew Jiff Lube was trouble, went to a different location, got same results.
If you love your rig, take your skid plates off - its only 4 bolts
