I've discovered that when I turn on my Tahoe's emergency flasher my battery dies after they're left on for about 20 minutes. After my Chevy dealer couldn't figure it out, I filed a case with GM and the case worker came back a week later and stated that this is a "normal" situation with this vehcle. This stunned me, and my local dealer. I consider this dangerous especially since I travel in the upper midwest. I hope i don't have any flat tires, etc, at night while i'm traveling! is anyone else experienced this? let me know. Thanks |

Something else would have to be causing the problem, perhaps daytime running lights or radiator fan if you are leaving the key in the ignition. Or perhaps the body control module is sensing you are still in the car, and keeping everything powered up. Is the key out of the ignition, when you have this drain-down? |

Replying to: miked26 (Jun 05, 2008 6:37 pm) Other things that have happened since I bought it a year ago, pre-owned with one owner, but seemingly in perfect condition: Transmission went out in winter, got new transmission. Radio and blinker stopped working suddenly a couple of months ago, they replaced radio. Windsheild wipers went on automatically and squirted out all wiper fluid without stopping several times. I think the electronic stuff is all related but they don't know how to fix it. By the way, it only has 38,000 miles. I have been in the shop atleast once every couple of months for the last six months. I love the comfort of the ride and the look of the car inside and out, but it has been so unreliable. I don't know if I should trade it in for something else or if maybe this is the end of the problems? Any suggestions? This is the first pre-owned car I have owned. I saved $17,000 buying it this way but I am hesitant to buy used again because of these problems.

| Have had electrical problems with recent SUV purchase, a 2007 Chevy Tahoe, has not been reliable but love the ride. Ready to trade in for a more reliable SUV or minivan. I miss the storage space of the minivan but enjoy the comfortable cabin, smooth ride and look of the SUV. Any other suggestions of new or used reliable SUV's or minivan's that would be around $40,000 or less? I had a Honda Odyssey before and it was a good car but wanted something more stylish, so got the SUV. My garage can't handle a larger SUV like a Suburban. Have looked at pre-owned Cadillac Escalade's but worried the reliablility will be like my Tahoe. Any feedback on pre-owned Toyota Seqouia's? I know the new ones are out of my price range. May be too large if same length as Suburban. I need to have seating for 7 in most of the time and the storage space in the back of the Tahoe is slim compared to the Odyssey. I currently have leather, DVD, sunroof, so looking for the same in my new car. Hesitant to buy pre-owned because of poor performance of Tahoe, but know I will probably have to with my price range since I want those extra's. Any suggestions? | |

Replying to: spidey3 (May 28, 2009 7:19 am) - accessories turning off, I believe that is normal to keep the battery from being drained down. That's controlled by the BCM (body control module) which is the computer that controls all of the lights and internal body electricals. I believe all of my vehicles do this (I know for certain a Ford and a Toyota I have both do). I've never sat in the Sub that long after stopping. I'd check the owners manual, I'm pretty sure this is working as it's supposed to. - I don't know what you mean by "automatic rear door release". If you are talking about the rear tailgate, and it not raising when you push the overhead button, you must be in park for that to work. Read the manual. Keeps you from ejecting the kids or your luggage while driving down the interstate. - Windshield wipers going on automatically. I believe this is trim level specific with the higher trim levels having automatic wipers (I know my LTX has this), is that there is a sensor on the windshield above the mirror. If the windshield stalk switch is turned on to one of the slower positions, the windshield wipers will come on when the windshield sensor detects water on the windshield, or something passes over the sensor (like your hand, or a squeegie). Check the position of the switch. I don't know that the washers come on though, I don't remember that happening. - What trim level is your vehicle? LT, LS, LTX, etc |
