| When stopped at a light or sign, when you released the brakes it feels like someone hit the rear bumper. this is cause by the york at the rear of the transmission is sticking. gm dealership will sand and lube the lube. this covers up the problem for a couple of months. if you want the problem fix it will cost you about $350.00. the yoke is not cover by the drivetrain warrenty. even though the yoke is the wrong one,because they will replace it with a nickle plated york and then the problem is solve. the york is the part that comes out of the transmission and hooks to the driveshaft. if the yoke grabs and breaks the rear of the tranny, the driveshaft will drop out and hit the ground. at high speed this could cause a fatal accident. | |||

| I purchased a new chevrolet silverado with the vortec max package in september of 2008. since new, the vehicle has idled rough and surged at stops. it feels like another vehicle has bumped you from behind. i have brought the vehicle in numerous times to be inspected under warranty. general motors came out with a technical service bulletin stating that if the vehicle has a rough idle with no check engine light it is a normal characteristic of the vehicle. the rough idle causes the vehicles rpm's to spike leading to the surge condition. i have asked for the vehicle to be repaired numerous times under the existing warranty and general motors has not taken action stating it is a normal characteristic. there are many other silverado owners with the same problem that do not believe it is a normal characteristic. any vehicle that feels like it was bumped from behind is a definite safety concern. i am scheduled for an arbitration hearing on july 11, 2011 with the better business bureau and general motors to discuss the problem. the idle/surge problem happens several times per week. my wife has also experienced the problem while driving the silverado and immediately called me asking what was wrong with the vehicle. i encourage all other general motors customers experiencing this problem to contact general motors, the better business bureau and the nhtsa. | |||

| I have a vibration on my pickup that has always been there since it was new, but it got worse and happens all the time on dec 22, 2008. it would vibrate around 65 mph but not often so i thought it may be road conditions. it has been at the dealer under warranty for a total of 8 days on 2 occasions. on the first time they replaced the torque converter and when i picked it up it was the same, i do not believe they even took it for a test drive. they have had it for 4 days this time and can not figure it out. *tr | |||

| I purchased a new chevy silverado ext. cab 4x4 ltz and drove approximately 30 miles from the dealership. after traveling through an intersection i noticed smoke coming from the engine compartment. i proceeded approximately another 50 yards in an effort to find a safe place to pull over to investigate the problem. before i could pull over the smoke increased and the interior of the vehicle almost immediately became filled with heavy smoke. i stopped in heavy traffic and used onstar to call for assistance then exited the vehicle and opened the hood to investigate the problem. i saw heavy smoke and flashes of fire coming from the left side of the engine near the catalytic converter. the fire extinguished itself shortly after turning the engine off and the smoke cleared and/or stopped after about five minutes. after the police and fire department cleared the vehicle to be moved, i contacted the dealership and got towed back. after a brief investigation the dealership service department stated that a component of the transmission was either improperly installed at the factory during assembly or immediately failed in the first 30 miles that the vehicle had been driven. this failure resulted in transmission fluid being sprayed directly onto the catalytic converter thereby causing the fire. *tr | |||
