    2012 XL Denali AWD steering shake over large bumps.

    My 2012 Tahoe LS 4WD started doing the same thing last year with about 62,000 miles. It does it with Mich. snow tires or Bridge. All Seasons. Took it in to a good front end shop and he said he has seen it before, but was not sure if it was the steering or struts. He said to let it go until it...

    2012 Tahoe 5.3 flex fuel will not start...Conclusion

    After chasing codes 0172 and 0172 for months, after trying new spark plugs and MAF, and after trying fuel system additives and checking wiring connections, my Tahoe developed a fuel leak near the gas tank. I took it in to the dealer and they replaced the fuel pump and some "nearby hoses". They...

    FUEL LEAK

    My 2012 Tahoe 5.3 flex fuel has developed a gas leak when running from around the gas tank. I'm not able to pull that tank out on my own, so it has to go in. Anyone in the Detroit area, have a dependable shop they can recommend?

    2012 Tahoe won't start

    2012 Tahoe won't start

    OK. I went out to my truck to try the code reader again and she started. There was no check engine light, but she did run rough. It slowly became normal after a minute. I tried the code reader and I got P0172, system too rich bank 1 and P0175 system too rich bank 2.

    2012 Tahoe won't start

    My Tahoe has 55,000 miles and has been very reliable. Last week, I got the check engine light, but it continued to run properly on my way home. Just a few miles. Next start, it ran very rough and stalled. Check engine light was still on. I tried cleaning the MAF, as it had never been done...

    2012 Tahoe 4wd Brake questions

    Hi all. Doing my front brakes and the small torx head bolt holding the rotor on is froze. Do I need to replace this bolt as I have been told that it is only for the assembly line? Also, does anyone know the torque spec for the large bolts holding the caliper to the hub? Thanks, Bill

    Those with LS. Do You Regret Not Getting LT or Premier?

    I have a 2012 Tahoe that I bought new and for the most part I am very happy with it. The one thing that I really miss is the thermostat heat and air. I am in Michigan and it seems I am always turning the heat up and then it is too hot and I'm turning it back down. Same in the summer with the...
