    Drove the 'ol girl home 3.5 hours on Friday. Went to start her the next day, the engine turns over but doesn't fire. I noticed that the fuel pump isn't priming when turning the key to the 'on' position. Did some research and come to understand that 2014's control the fuel pump through a Fuel...

    TPMS relearn on 2014 Denali

    I've read a few threads on performing the relearn on 2014 Suburban/Yukons. Didn't see a lot of posts, so I thought I'd share my experience. Had tires rotated during a recent oil change. One tire has a slow leak (I believe it is the the valve stem) which I have not fixed yet. So the next day...

    Forget HIDs, I just want my headlights to work

    When I purchased by 2014 Yukon Denali (used) I noticed that someone had hotwired the fog lights to the high beams, essentially forcing the fogs to be available regardless if hi/low beams were active. One day I woke up to a dead battery, as the hack wiring job had jiggled a bit and forced the...

    Anyone else think the new suburban looks like Ford Flex's big brother?

    Still trying to warm up to the new body style. I like the 2 previous generations of Suburbans, but this new one still needs to grow on me. Here's the '07-14 for comparison. And the previous generation

    Reliability 2010 vs. 2007?

    I'm in the market for a new Burb or Tahoe. I have an '03 burb with 180K on the clock and aside from normal wear-n-tear it runs great, no leaks or major problems. From my reading, it appears that the '07 models have electrical issues (no start, battery assinations, etc.) Did these issues get...
