Vibration at hwy speeds, tires rebalanced rotated and balanced at three different places including dealer twice. All places say tires R bad but will not help in replacing them unless I buy other tires. They only have 15,000 miles on them. I feel Goodyear should replace these tires.

The vehicle has an established, measureable and documented vibration problem that randomly increases & decreases in applitude & frequency at all speeds. GM is unable to resolve after 12 dealer attempts to address, including multiple sets of tires, rear differential, drive shafts and shock absorbers all failing to resolve the issue. GM stated vibration is inherent to the design and no further action needed or will be taken ever for vibration, regardless of circumstance. Such a vibration is a significant safety defect because it is essentially like cutting wires to warning tell-tales by removing a driver's ability to discern tire/suspension/powertrain/steering problems that can only be identified by feeling a vibration (such as a loose wheel or damaged suspsension components) prior to a catastrophic event, especially at high speeds. Not only for the vehicle occupants, but also for any road user when it results in the driver loosing control of the vehicle. GM's own attempts to fix the vehicle with the list of parts above irrefutably supports the inability for a driver to identify the source of a vibration. If experienced technicians and subsequent corporate engineers cannot recognize the vibration as being different from wheels, suspension, powertrain; then a normal driver will have no such warnings available should a potentially catastrophic safety issue be present. Further, since GM refuses to address any further vibration issues with this vehcile, it is like have a airbag warning tell-tale continuously illuminated whether or not a problem exists & GM stating to just live with it. In other words, if I get a loose wheel, I guess GM figures I will know it when it falls off. In addition, to safety defect described above, the vibration is an extreme source of driver distraction & driver rage as attempts are made to produce and/or reduce the vibration while driving.

The contact owns a 2014 Chevrolet Silverado. While driving at approximately 35 mph, the contact heard an abnormal noise coming from the front wheels. The contact stated that this was a recurring failure. The vehicle was taken to the dealer for diagnostic testing. The technician stated that it could be the tires. The manufacturer was not notified of the failure. The approximate failure mileage was 6.

The contact owns a 2014 Chevrolet Silverado. While driving at approximately 65 mph, the vehicle shook violently without warning. The failure recurred numerous times. The vehicle was taken to a dealer where it was diagnosed that the driveshaft failed and the tires needed to be replaced. In addition, the drive line needed to be aligned. The vehicle was repaired, but the failure recurred. The manufacturer was made aware of the failure. The failure mileage was approximately 600.

I purchased my 2014 Chevrolet Silverado on 7/11/14. On the way home I called the dealer to tell them that it had a bad vibration when driving at highway speeds. The first repair was attempted on 7/25/14 with 1207 miles. I have had the truck back at least 8 times for a repair. The dealer has replace tires. They have balanced the tires at least 6 times that I know about. They have replaced the drive shaft. The have replace the ring gear and pinion. Replaced the entire differential ( they swapped it from another new truck) they have repositioned the motor mounts. Now they are wanting to replace the rear differential again. I have been patient with them trying to let them fix the concern. They have a General Motors service engineer involved and he has several parts ordered for it. The dealership had talked to their factory rep and at one time they talked about GM buying the truck back and getting me another truck. I don't feel the truck I have is safe. It has had the wheels off more times than I would have rotated my tires in 150000 miles.

Drove home from dealer on highway, very noticeable pulsing vibration felt in gas pedal once I hit 65mph. Vehicle also "shakes" at a constant rate at 50mph, and more violently at 82-85mph. Drove up to 500 miles per dealers direction, problem still exists and has not gone away at all.

Vehicle has vibration, more noticeable at higher speeds. The vibration comes up through the steering wheel and also can be felt through the gas pedal. The wheels/tires are suspect, and I am concerned about a slipped belt and subsequent tire failure. This has been reported to the dealer who states "vibration is normal".
