#169 of 428 2007 Chevy Tahoe electrical issues by westjr88

Jul 25, 2011 (8:11 am)

I have an '07 Tahoe and just recently the check engine light came on and later that afternoon, the voltage gauge started going crazy and the fuel gauge stopped working. The next day, my wife was driving to work and it slowed and the reduced engine power light came on and it started coming and going and had no power. She managed to get it back to a shop near home where they changed a crank sensor and the battery. Same problem. Took it to another mechanic who put it on the computer and it showed 62 codes. So far, i have $535 in it and same problem. I know it has to be some little wire somewhere or something stupid like that but i'd like to find it before i sink alot more money into it. Anyone ever have the same type of issues? Thank you for your time.

UPDATE: Electrical issue fixed. My problem ended up being that my radio had a short in it due to the kids putting a piece of change in it. I unhooked the radio, put in the new fuse and it never blew again. I replaced the radio about two weeks ago and life is good.

I am recycling a Military Police 2007 Tahoe for a small state police department. All the windows, locks, mirrors, front A/C fan, and the all gauges & ODO are not functioning. My first thoughts are during removal of police equipment something came unpluged or damaged...any ideas on a good place to start looking???

Probably more likely that they blew a fuse when taking out all the old stuff. Check all of the fuse boxes, use a voltmeter if necessary to see what has power, and what doesn't. Track it back on the electrical schematics to see what is blown.

I own a 2009 Chevy Tahoe and have been having what appear to be electrical issues for almost two years. It started with my navigation system. While driving, the screen would go black and it would shut off/on. I had the system replaced twice, but the issues continued. Then, other strange issues began occurring randomly: 1) warning lights flash on and off while driving; 2) outside temperature reading sticks at 55 degrees or 78 degrees; 3) door locks click on and off while driving; 4) key fob does not work; 5) dome lights go black immediately upon shutting off the car - no electricity in vehicle; 6) unable to start car on first attempt, but then hear clicking sounds signaling the return of electricity; 7) headlights alternate between dim and regular strength while driving; 8) all power/electricity turn on and off while driving, resulting in the car losing power/stalling and having to coast to the side of the road. I have taken the vehicle in to the dealer 3 or 4 times, but they could never duplicate the problems while the vehicle was hooked up to the computer, and sent me home every time as though nothing was wrong. I recently contacted GM to find out if others had reported similar problems, hoping to get information I could take to my mechanic so that he could fix the defect(s), but GM dismissed my complaints after the customer service person spoke with the service department at my dealership. In order to put less strain on the electrical system, I don't drive with the radio or navigation system on anymore, and as much as possible, I try not to use the air conditioning. My children are so worried about the car jerking to a stop while we are on a busy street that they do not want to get into the car. My 12 year old son is so concerned that he spent more than an hour searching the internet this week to find out what is wrong with our car. After reading all of these posts, it is apparent that GM is, in fact, aware of these same issues with hundreds of other vehicle, but has elected to ignore the consumers and make no attempt to remedy what has clearly been mass production of defective and unsafe vehicles for many, many people. After reading what everyone else has written, I am going to bring this information to my service department hoping that they will be able to identify and diagnose the defect(s). After paying more than $50,000.00 for a "lemon", why am I the one doing the work of the "factory trained" GM technicians? Obviously, defective GM vehicles are the reason why people choose to buy foreign cars.

Ran into the same problem the other day for the first time with my 2008 Tahoe. Thought it was a fluke thing and it did it twice to me then went away. Thought ok maybe that was the end of it. But when it did do it it was like my Tahoe was possessed everything was going on and off. Every gage looked like windshield wipers going back and forth. Every indicator light was blinking on and off. Door locks where unlocking and locking so fast that the actuators got to a point where they seemed like they could not keep up and started jamming up. Then it started to stall out. Next day my wife was driving it and it started doing it again, scared the hell out of her. Its only a matter a time before this causes a major accident such as a fire or airbags inadvertanly deploying because of the sensors getting affected. It will happen to one of us who are having this issue eventually God forbid. I know if it comes to that GM is going to be begging for mercy. Going to be taking it in this week but I'm sure I'll get the, can't duplicate the issue answer. Its a shame at the money we paid for a nice family vehicle to have these issues.

My 08 Tahoe LTZ in the shop right now for this very thing. Truck acts like its possessed! It all started with a warranty replacement of a cracked dashboard. After getting it back, the nav/radio would go off and restart on its own and different warning light would come on. (Random occurrence) but often. Then this past saturday the truck completely shut down after being turned off. No electrical thing would work(lights doors locks and would not crank; funny clicking noise and needles jumping on odometer)I had to disconnect the battery to "reset" the truck. Took to dealer monday they could find nothing. Tuesday truck became "possessed" with the rest of your symptoms.locks engaging on their own various warning lights nav radio go out car jerks and slows..... what is going on?

The problem with my truck ended up being a bundle of wires that dropped down against the drive shaft and several were chafed in two. Problem solved.

#178 of 428 2007 Tahoe LTZ with seemingly electrical problems by rancez

Curious to see if anyone else is having the following issues and what was done to resolve it for a 2007 Tahoe LTZ, costs and if it was covered by warranty.
 
At 70k miles I just started recieving the error messages with stabilitrak and traction control as well as having delayed starting. After turning the key to start, you can hear it cranking over and over with no start, it would even continue to crank once I let go of the keys. It would only stop when i turn it back. When it would finally start after cranking, the vehicle would "jerk" a lil. During driving, the stabilitrak and traction control and check engine warning lights would go on and off intermittently. One effect during driving is that it would seem like the vehicle will die during sharp turns (like a u turn) or when the vehicle is in reverse. Another wierd behavior is an error message that basically says engine is running hot so A/C has been turned off, but the engine is running cool with no over heating heating.
