    2016 rough idle

    Mark-- Your post is EXACTLY what the assistant service manager at my dealership told me. He also told me-- Get an aftermarket tune to raise the idle RPM 100 or 200 RPM. We are unable to do it because of emission regulations. Wow. Thanks GM. I bought my first new GM product in 1968. (Yes--I'm...

    2016 rough idle

    I am convinced that the low RPM is causing the motor to vibrate because of ????. Cylinder deactivation?? Fuel pump problems? This area might be discarded as an individual at the start of this conversation did have a pump replaced. The dreaded "fuel pump ticking" has finally killed something...

    He asked. I answered. I will give glowing reviews about my 2009 Tahoe LTZ, 2003 Tahoe, 1999 Tahoe, 1992 Tahoe and so on if you wish. I'm too old to be fighting with a car company over an inferior quality vehicle. Basically-- Transmission and ring and pinion replaced at 26,000 miles to cure a...

    I have been a loyal GM guy since 1968 when I bought my Firebird 400, Ram Air convertible. (Wish I still had that one!) I usually keep vehicles 6 years or until they reach 100,000 miles. My wife had Camaros and Impalas for years. She now drives a Honda CR-V. The later Impalas would just not...

    2015 Ltz noise at 60mph

    I only have about 1500 miles on the Tahoe since the repair. I'm hoping it does not become noisy again. But----.

    2015 Ltz noise at 60mph

    I have read your comment about the rear differential. I had the EXACT same noise that started at 1,200 miles on the odometer. the dealer had it many times--in fact I had a loaner for 43 days as they worked on it. The solution--New ring and pinion gears. No more noise. I would strongly suggest...

    Issues Water Leak, Navigation, wind whistling noise

    Leak=Shark fin antenna. Noise=Trim or shark fin antenna. Navigation=Shark fin antenna or computer failure. Water can do a lot of damage when it manages to get into something that should be protected.

    Screen goes blank with playing audio via Bluetooth

    I had the same problem (2015i) some time ago. After three trips to the dealer, they replaced the HIM module and that cured everything. Be safe. Bob
