I’ve got a 2010 Tahoe LTZ with 144k miles and wondering if I should take the this car or rent a car on a 3000 mile road trip this summer. I do all the basic maintenance; Mobil 1 oil, already changed power steering fluid, flushed brake fluid; tranny and radiator flushed; all spark plugs replaced. Has original engine belt, starter etc. It has been very reliable since bought new. Just finished a 1000 trip no issues. If I take this Tahoe, what preemptive service or part replacements are recommended?

Three thousand miles at high speed is what 50 hours or so? I think she'll go another 50 miles without issue.

How's your suspension, steering, brakes and tires? How old is the battery?

There are guys on here who make such runs with over 200K miles, mine's at 185K and we're doing a 4K mile trip this year with it.

Last July, I took my 2005 Z71-150k miles on a 15 day 5500 mile trip and had absolutely no problems. Up and down passes at full accel. Performed flawlessly annd I do all my own maintenances. I say take it. I would do the belt(s). If is close to next oil change time, do it before you go.

Ditto to my brothers above. 2008 with 165K at the time. Did (2) 3000 mile trips out west last year. Off road trails, mtns, etc. Still ticking at 176k now. Just make sure you're up to date on fluids and filters. Tires all balanced, let her rip

The only time I've ever had a catastrophic vehicle failure has been new vehicles (had a Denali toss a harmonic balancer at 1k miles / ecoDiesel went into limp mode at 2k / latest Denali lost a turbo at 20k).

The high milers seem to be less catastrophic, more so issues that build over time and warn yah as they get worse.

Unless you're the driver that just turns the radio up louder......

From a preventive perspective
- check the usual's (air/oil/coolant/etc); basically all the fluids
- check the suspension (lift it up, yank on the wheels, up/down and left/right); this will find hub/bearings/tie rods/etc
- check the u-joints

Beyond that, maybe take a scan tool with and simple tools if you are feeling ambitious.

Welcome from Miami Beach&NYC Rick!

I vote for you to take it on your 3K miles trip. I have 150K miles and still go back and forth to NYC 2-3 times a year. No plans on selling it anytime soon.

If you put more then 2500 miles on since your last oil change I would change it out before you hit the road. I generally change oil every 5K miles but do it before that if I am going on a long trip.

I know you do the basic maintenance yourself but I would let a good independent mechanic change it out before you leave just to do a once over just to play it safe in case you missed something. But that is just me.

Moved you over here from the 2021 section.

If your belts are original, replace them for sure before you go. If you haven't replaced your coolant tees at the firewall, that's another good item to have done. They get brittle and fail and you're are due if they haven't been done already.

I have 231K on our '07 and have 8K miles worth of trips planned with it for the spring already, with the first one starting this weekend.
