"I love the size and drive of my suburban but it has had some issues. When you spend $40k on a brand new vehicle you don't expect things like this to happen. We have had this 1 1/2 year and we have put just under 28,000 miles on. First issue:
the driver side & rearview mirrors are always dim at night and still has a problem after having the rearview mirror replaced due to a sensor and the driver side mirror replaced.
The thing has died 2X's while being on accessory for 10minutes. Had to have it jumped both times.
Fuel mileage is nowhere near what it said it would be. The only time it goes to 4cyl. is when it coasts.
Now it is using oil. After last oil change we drove 2500miles to texas and back and had to add a quart when we got back. Just 1200 miles after that we had to add another quart. We are now doing an oil consumption test on it.
I think we got a lemon. Not what I want when I need something more reliable to haul my family around."
"My '07 is setup with the 6.0 and the 4.10 rear end towing a 27 foot boat back from southern california up baker grade and cajon pass with the air on, was a breeze.As a matter of fact i blew the doors off a new tundra v-8 that was towing a much smaller boat coming up baker grade... As far as safety goes I am a walking miracle I was hit in the driver door of my 2004 at over 90 m.p.h. and walked away without a scratch on me, plus the onstar automatically called for emergency help and they were there in no time at all. This truly is the ultimate all around SUV!! Reliability has been superb on this vehicle with nothing more than basic maintenance needed to keep her happy."
"Love my '07 LTZ. 6 kids, 3 big teens, we needed the room. Lived at the end of an unpaved steep hill, needed the power. It delivered it all. Only complaints are at the gas pump, and w/the 3rd row seats. At 5ft2'' I have to climb in teh trunk to lower or fold. Power button would be great. Still love it!"
