Highest Mileage Thread
2011 GL 450 44k miles. Front strut replaced and ignition replaced.




Well maintained to that point, but don't have a complete list of work.
Since I got it:
Glow plug controller
Rear brake pads
Tires at 20k (Goodyear LS Eagle), Tires again at 45k, went with Dunlop 5000 non run flat and really like the ride...way better than run flats.
Do all my own maintenance including the big 40k

Other than usual maint items, most of which I do myself -
Hitch receiver reinforced, just to be sure...
Parking sensors in front failed and replaced
Blind spot indicator in drivers side mirror failed and replaced
Security module that detects proper ignition key died and replaced
Spring loaded claws in cup holder broke and replaced
Roof rack cover broke and replaced
Engine sensor (forget which one) failed and replaced
Recently Started to feel and hear vibration in rear of truck when backing up under load or uphill at around 1,800 rpms. Watching...
Stock run flat tires are about done.
Front brake pads are ready to be replaced. Rotors are still in spec.
Planning to do the 40k mile service except transmission myself. Quote from dealer is around $500 for the tranny service.
