How Reliable?

[MaximusGTR]

I'm planning on adding a Tahoe to my collection of vehicles. I want to get the 2000 and up style. How reliable are these trucks? I'm gonna get it used. Around 40,000 miles...... With normal driving and maintinance how long will these trucks last? Are they really big gas guzzlers? Most likely I'll get dual flowmasters or just one, will this effect my trucks life? How about 22 inch rims? When I get them, will it effect my tranny. Once again, I plan to do normal driving. I own other cars and may use a car to go to work but I may only use this truck on the weekends only....... Please Help.... Thanks

I have been working on these trucks for awhile now they seem to hold up pretty good with the proper maintenance done to them.

As for being gas hogs anything made by GM with a V8 sucks gas the V6 are smaller use less gas and the base engine is the same design. It is up to you for what engine you want. What purpose you need get what will work.

As for 22" wheels the computer on these trucks needs to be programmed for the size tires you have. GM has many different sizes you can use as long as it is listed and apporved you can put that size tire and rim on. If you use an unapproved tire you can have trans, abs, engine problems so make sure it will work before you spend the money.

Thanks for the reply, your definition of "hold up pretty good". Is that pretty good over 100,000 miles? I see people still driving the 95 Tahoe's and the k-blazer so it seems these trucks last pretty long. So its recommended to get one of these trucks over an Explorer or Expedition?

The reason I say they hold up pretty good is because I work on them for a living and I only see them when they are broken or need serviced. Hardly ever do I need to fix anything that is above service work> Just for the record I only drive GM, I breathe GM and I only speak GM, just call it loyal to my job.

I own 2 Chevy's with 350 V8's, a '93 Ext cab p/u and a '99 Tahoe 4X4 and they both average 17-18 MPG's which is very reasonable for vehicles of their size and power. I've known owners of Blazer's with the 4.3 V6 that get the same mileage I do.

I don't know how reliable the newest style of Tahoes are. I can attest to the reliability and toughness of my '99. It is an ex-Ranger's vehicle and it has been off road 50% of it's life. It's been driven hard and it's been on some realy bad roads. The good thing is that it was serviced regularly. I bought it at an auction with 89,000 miles. I have had it for over a year now and it has just over 100,000 miles and is still running strong and the body is still tight. I have the all the service records from new and it never needed anything major. Knock on wood. I'm keeping my fingers crossed.

The 2000 & up are great except for the 5.3 litre engine. This engine is utter crap & will die long before 100,000 miles. Avoid it at all costs.

I haven't seen the type of problems you have had with the 5.3L! Lets hope yours was the exception! I work on these trucks everyday and I have yet to do any major engine work!

I think I'm sold, I'll be getting a black one within the next 2 months.....

Too bad I'm not located near you... I'd love to have an expert mechanic look at the thing to determine what the F is wrong.

I borrowed my friend's snap-on scanner & came out with two errors. We can't figure out why

Consider yourself warned, SPEEDER94. If you have a beef with me then send me a PM... otherwise don't waste my time

Researching the 5.3 engine in the Tahoe/Suburban will yield all sorts of concerns over an engine knocking/ticking noise, with no real resolution from Chevy.

Prior to owning my 99 Tahoe (127k miles), I did not own an american car for years. Of the big 3 automakers, I believe that GM has consistently put out the highest quality product. The Tahoe has been, accommodating and a pleasure to drive...not to mention fun!

All suv's have their idiosyncrasies, but I've found that the Tahoe's are easy to live with. Parts and service are affordable, and driven responsibly, the Tahoe gets decent gas mileage.

As with any vehicle, the key to longevity is diligent maintenance. I've an acquaintance with over 300k on his Tahoe, I'm aiming for the same. Good luck with your purchase.

I have 2 2000 GM vehicles, a Silverado Z71 and a Tahoe LS. Both are 5.3L V8. I see approx 17-18 MPG consistently, the truck especially so due to the cover I fitted on the bed.

The Silverado is an amazing vehicle and has been a complete joy to own, however the Tahoe has been lack luster to say the least. To put it mildly, I submitted it as a lemon because I was so disappointed with it and being continually fobbed off by the dealership. It runs fine now, but the power window reliability is poor.

I am not saying that other Tahoes are bad, only mine, but I would recommend you get the 5 year warranty if you buy one.

I have had no real probs with the engines, the Tahoe started knocking at start up, which cleared up mysteriously.

Any change in fuel brand/octane or motor oil?

I tried "top end cleaner", and a fuel system treatment from an auto shop... but that did nothing (other than drain my wallet). For now, I'm switching to Chevron super unleaded & adding an octane booster. Or maybe my knocking/ticking problem is a result of the engine being too clean?
