Driveshaft problems of the 2015 Chevrolet Silverado 1500

The contact owns a 2015 Chevrolet silverado. The contact stated while driving approximately 75 mph the vehicle began to shake, with vibrations coming from the center console and the passenger front seat. The contact stated no warning light was illuminated. The contact had not taken the vehicle to a local dealer. The vehicle had not been diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 67,500.

Severe vibration between 65 and 80 mph. Driver must stay below 65mph. Thats dangerous on a interstate highway. Dealer unable to repair. Driveshaft specialist inc. Tampa FL , told me drive shaft is defective, the material is too thin and it must be replaced , with a new one of better quality ( thicker metal) cost is 600. To 800. Usd. This truck has only 32,000. Miles seems to have started around 25,000 miles.

Under acceleration and cruising highway speeds the vehicle vibrates and shakes. It is felt in the floorboards, seats, pedals, steering wheel and in the bed of the truck. Vehicle has been into the dealership numerous times getting alignments, wheel balances, and pico scope tests. Under my own investigation I found the factory driveshaft was not straight, out of round and out of balance so I had a professional driveline shop build me a new one. Also under my own investigation I found the rear axel hub flanges were out of round as well and the local dealership had replaced them. Vibration still exists and there seems to be no answers coming from gm.

While driving on the expressway, the drive shaft broke off. This caused the vehicle to lose control. Luckily, the vehicle was able to make it to the side shoulder without causing an accident. The dealership replaced the drive shaft and rear differential, but no one (even when I contacted gm priority care) could inform me why this happened. With me having two small kids, I am still concerned that this could happen again.

So due to known issues with the yolk on the differential, the lag in the transmission shift and engine communication leads to extreme vibration at highway speeds and clunking and jerking while driving around town. So when the transmission shifts there is a delay in the motor recognizing it so it revs up some so when the transmission finally finds the gear it causes it to kick. And since the yolk has play in it, it causes the differential to clunk as the rotation of the driveshaft catches up at a quicker rate. Which leads to more looseness in the yoke and creates a wobble in the driveshaft. And an unsettling sound while driving around.

Drive shaft is out of balance causing it to shimmy on the highway, called gm several time no response to problem tokk back to kupper chevy in mandan nd they won't fix needs new drive shaft been complaining since 5000 mile now has 54000 and still will not fix.

Transmission shifting rough ,sometimes when shifting into reverse it bangs loud ,thinking the drive shaft is going to fall out, when driving the shifting of the transmission jerks nothing smooth about it shifting.

My truck had approximately 10 miles when I purchased it in Dec 2014 and has been in the shop pretty much ever since. Immediately after purchasing the vehicle, I felt a very substantial vibration around 76+ mph. Initially, 2 tires were replaced and balanced; that did not correct the problem. Then the dealership indicated that gm said I have to put 500lbs in the back of the truck and the vibration will stop; this is not even remotely practical. Subsequently, the tires have been rotated and force balanced several times throughout the past 2 yrs. In June 2016, the dealership stated the problem was that the tires were mounted on the rims incorrectly and replaced all four tires and balanced them; the vibration continued. After trying to schedule another appointment with the dealership over the same issue, they will no longer call me back. I have attempted to schedule an appointment at least 8 times within the past month to no avail. Several people have indicated the problem is quite possibly the drive shaft b/c the entire truck vibrates while driving down the road. Therefore, I took my vehicle to another dealership where they told me I need to rotate and balance the tires. After discussing the history of the truck with them and requested the service dept. Check the drive shaft, they stated the service manager said it is not the drive shaft (which was not inspected to my knowledge) and told me the tires need to be forced balanced and they could not help me. This dealership referred me to another dealership for assistance. I have been fighting this issue for almost 2 years now and cannot get help. Further, neither of the dealerships have made me aware of the bulletin and have not tried anything past the replacing & balancing the tires. The vibration is so bad other things in my truck are starting to come loose and vibrate.
