    Buying advice for a 2017 Denali - what to look for?

    yes i decided against buying this one. it was a good clean and looked after. the gear shift from 1st to 2nd was rough and there was a grinding sound from the back (maybe the diff?) at around 60mph. all fluids had been changed at regular intervals but i guess the model year is problematic in...

    Hi all, i am looking to buy a 2017 Yukon Denali. It has around 60,000 miles. Still with the first owner. I will do a test drive tomorrow. What are the known issues with it? I understand it has the 8L90 which is prone to issues? What should I be looking for and what immediate things are to be...

    2015 Tahoe LTZ - intermittent brake assist loss at low revs - vacuum pump?? - SOLVED

    i am based in Riyadh, Saudi Arabia. I went to the GM dealer I bought the car from. It was not covered by GM (should it be??). I paid USD 406 for parts and labor. It was a 45 minute job.

    thanks everyone for the inputs. got the vacuum pump replaced from the dealer. the problem has been solved. its been almost 2 weeks now and no brake-related issues. in fact the brakes feel much better.

    Thanks for this. Just wanted to know what are the symptoms of a faulty vacuum pump? Also, the location of these abs sensors? How to check and replace

    Checked the lines, no fluid. Also fluid inside the booster is clear, no oil there.

    Do you suggest getting the vacuum pump changed or not? The issue is not that frequent. But when it happens in traffic its alarming

    Got it. So you're suggesting tightening the belt first before replacing the pump?

    So the booster and the vacuum pump are two different things right? I am assuming the booster is fine and its the pump thats going. The belt seems to be in good shape. But I will change it regardless.
