    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.

    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?

    My Tahoe has 59,000 miles and has been great. It has new spark plugs and wires. Newer battery and starter. New air filter and MAF sensor. Lately it has stumbled on cold start, but runs great after a 60 second warm up. Today it will not start at all. It is warm today in Michigan at 60...

    2012 Tahoe won't start

    OK. New MAF sensor is in. Fuel pressure tester is hooked up. Showed 20 with ign. on, but not running. Showed 60 when started, running rough. Then settled down to a nice idle and fuel pressure is steady at 42. Shut it off for a few minutes, then tried again. Erased codes. Fuel pressure...

    2012 Tahoe won't start

    Yesterday I tried starting it again and it would not run. I just went back out and unplugged the MAF sensor and it started right up.

    Shut her off and let her cool. Started again and got the same two codes again. Yes, all of the engine is original. I have only done tires, brakes, oil, battery, and filters.
