ekimsinnigcm posted a topic in 2014-2018 Silverado & Sierra TroubleshootingHi Everyone, So my truck has been at the dealership two times officially now. This 3rd time I had my friend look over it and he said the truck was within GM's specs. I don't know what GM's specs for vibration are but my vibration is in the mid 70mph range and excessively vibrates and then smooths out. This is a constant cycle throughout my commute. I am going to pull my driveshaft and take it to a shop that specializes in driveshafts. I know several people have had their driveshafts replaced under warranty and it did not correct the issue. My thoughts are if your truck originally came with an out of spec driveshaft chances are there is a whole stockroom somewhere in the Parts Department that has out of spec driveshafts mixed in with the ones without issue, hence the reason some people have no luck with driveshaft replacement. I really feel this could be one of the major issues behind all of this especially when there is documentation instructing the technicians at the dealerships to use hose clamps to balance the driveshaft. I'm sorry but I don't see hose clamps as a permanent correction to this issue. I will update this post when I get the results from the driveshaft inspection. Please feel free to share your thoughts and bounce ideas around. Collectively I believe we can find an aftermarket fix for this issue, it may not 100% resolve the issue but will at least save people from taking huge losses on trade in (if you did not go through a buyback/lemon/customer satisfaction program). (A lot of people are trading in / selling their trucks because of this issue) ***UPDATE 01-22-2016*** I contacted the Team at Precision Shaft Technologies (http://pstds.com/) in Clearwater FL and they were able to squeeze me in as a walk in. (Not there normal protocol. They were super friendly, informative, and VERY helpful!) I drove up there and pulled the driveshaft in their parking lot. They then put the driveshaft on a machine and it was a near perfect balance. They added one small shim to the U joint to get it perfect but I'm sad to say the vibration is still present and there was no change. However, when I returned home I put my truck up on jack stands and ran it up to the speed I had issues at (per GM's service docs) and there was NO vibration. I was extremely confused at this point. I dumbed it down and looked at the rear wheels while the truck was in drive (idle speed) on the jack stands (be sure to block your front wheels and disable traction control / StabiliTrak if you plan on doing this on your own). I noticed my left rear wheel has a slight flat spot it in so much so that it's extremely difficult to notice. I have not had a chance to swap a known acceptable wheel to the rear at this time. When I do I will update this post. A recap for a description of my vibration: -72-74 MPH there is a cyclic vibration. Roughly every 7-8 seconds the truck has a vibration and then the vibration disappears.
I have a 2015 Silverado Crew Cab 4x4 with a base radio. Sometimes when I start the truck the radio does not play music correctly. All chimes work, the display works, and if I crank the volume to the max I can hear the sound very faintly in the rear speakers. Tried messing around with the fade/balance to see if it was a bad speaker, but it seems to be something wrong in the radio. It will intermittently blast sound, then cutout, then come back on again. I'm curios if anyone else has had this same issue.
1997 Chevrolet Silverado z71
jake_allgeier posted a question in Ask the GM TechnicianHello, I'm having trouble with my low beam headlights. They are intermittent and only happen when I drive the truck. I've had a fuse replaced, headlight relay, headlight switch, and the multifunctional switch replaced and the problem still persists. Can some one help me? Please and thank you. I have a 1997 Chevrolet Silverado z71.
My 2004 Chevrolet Silverado Z71 extended cab truck will randomly set off the alarm when sitting with the doors locked. It will also randomly post a drivers door ajar message while driving even though the door is shut and latched. Also sometime the radio will not shut off when the key is pulled. It will also do the key in ignition chime when the truck is off and the drivers door is closed. Sometimes the interior lights will not extinguish when the doors are closed. It appears to me that it must be related to the drivers door latch switch but I can't seem to find anything online as to how to troubleshoot the switch. I suspect the switch is bad in the door latch or else the wiring is broken from the door to the body from years of opening and closing the door. If anybody has pointers/schematics as to how to troubleshoot it I would appreciate it.
Ignition - Dead - Ghost - Wont Start - Intermittent
gmchorrors posted a question in Ask the GM TechnicianNov. 11, 2014, Northeast Pennsylvania, 2005 Sierra 1500 5.3L *Work Truck w/109000 miles on odometer: After driving for about an hour, I stop at a customer's home [at about 3pm], shut truck off, take key out, get out, and close door. About 20 minutes later, I get back in, place key in ignition, and turn key. Nothing. No starter sound; no lights on dash. It's like there's no battery. So, I breathe and try, again. This time, truck starts right up, like there's nothing wrong. What the heck was that? I driveicon1.png home, park, turn truck off, and get out. At home, I take battery out and place on a charger overnight. ...................... Nov. 12, 2014: I take battery to auto parts retailer who tests it. The test reveals, the battery is good (should start truck) but, is weak (needs a charge). So, I put battery back in truck, connect the cables, get in, put key in ignition, turn key, and it starts right up, like nothing's wrong. While engine is running, I place a load tester on battery. Test reveals, battery is good and alternator is charging well. While running, I drive truck to mechanic, explain everything I know to mechanic, and leave truck. Two days later, mechanic gives truck back, and says, it started right up "Every Time", and he can't find anything wrong with it. The mechanic charged me $20.00 ....................... Nov. 15, 2014: After driving for about 45 mins, I turn truck off, take out key, and get out. About two hours later, I get back in, put key in ignition, turn key, and it's like there's no battery. I leave key in ignition and get out, walk away for about 5 mins., come back, get in, turn key, and truck starts right up, like there's nothing wrong. ...................... Nov. 22, 2014: First thing in the morning, I disconnect the trickle charger and click the Viper remote starter button [twice in a row] to start the truck. Nothing happens as if the system is dead. So, I wait a few seconds and try, again – nothing. So, I wait another few seconds and try, again. This time, the truck starts right up like there’s nothing wrong. …………………….. I can't find a TSB, Special Service Adjustment, or other such bulletins on this issue however, I've discovered other GM vehicles with such related problem(s). Read this for instance: http://www.carcomplaints.com/Chevrol...starting.shtml and, http://www.gm-trucks.com/forums/topi...is-dead-today/ * work-truck: In 2007, bought it 2nd hand from a Stroudsburg, Pa GM dealer. It had 7,800 miles on the odometer.
