While driving on the hwy. Towing my 28 ft 5th wheel trailer on level ground we experienced a loud bang and the feeling like something in the driveline had broken. No engine malfunction indicators were displayed on the console. No further incidents have happened yet, but it is constantly on my mind.

Failure Date: 02/19/2006

The transmission clunks when shifting from 2nd - 3 rd and at times the engine will rev and finally it will take off, this has caused an issue when going through an intersection. The dealership attempted four repairs and it is not fixed. The issue started when the vehicle had 6k miles on it and it is getting worse. The speedometer is sporadic in that it will show speed reduction/increase in segments - as if it were sticking. The erroneous speed indication causes an issue when going too slow or too fast in traffic.

Failure Date: 07/26/2005

1999 GMC Sierra 1500. While driving the truck for about 45 minutes to an hour and if stopping at a stop sign or red light the truck will not shift from first gear to second gear properly. Once the truck does shift it is a very hard shift, and if on wet or slippery surfaces the truck will squall the tire. This started around 60, 000 miles. This does not happen every time, it is hit or miss. While pulling across three lanes of traffic the truck shifted properly and was almost hit by on coming cars. Took vehicle to the dealership, and they said it was the transmission. It was a common problem with GMC trucks. There is a kit that is made to fix this problem, but transmission must be replaced and the repair cost is between $700 - $1,800. This happens 4 to 5 times a week.

Dt: the engine has died, once while driving and once at a stop sign. The transmission was jumping and was put in neutral to steer to another lane. The other time there was no sign of a problem before engine stalled out. There has been many times this has been in the shop due to transmission problems. Have been with gm a few times and they came to the conclusion that they would send a representative to check out the truck. They never sent one, as of today, gm said that they didn't do that. Consumer wanted a buy back. Consumer talked to bbb today, they said that the consumer might be getting a call from gm. Consumer had the vehicle in the shop 3 times, all due to transmission and engine related problems. Dealer has tried to fix problem 3 different times, but that is not working and has made condition worse than before.

Automatic transmission would intermittently hesitate before catching in gear while driving. Vehicle has been to the dealer on two separated occasions and they were unable to duplicate the problem. Consumer was concerned that this vehicle maybe rear ended. The truck was on an incline in overdrive with my foot on the brake, let off the brake and gave it gas to merge into traffics and the truck wouldn't accelerate. It hesitated until felt like a gear caught and then into traffic instead of going when it needed to go. The second time was almost the same way.

I drive a 2003 GMC Sierra and there is a transmission problem it makes the driving very dangerous especially at highway. Speed. The vehicle cannot stay strait it either pulls to the left or to the right. The feel of the vehicle isn't right like if its dog tracking. There are clonking and ticking sounds coming from the transmission just from shifting from drive to reverse,reverse to drive. . . Park. While driving when engaging the passing gear sometimes you hear that clonking sound like if there was a slack in the transmission. I had this vehicle since July 2004 and since then I've been to the dealership a number of times everytime they said that everything was ok and showed me paperwork stating from gm canada that clonking, ticking etc. Etc. Were normal operation of the transmission. It cant be cause I had a 2001 GMC truck which I traded for, that drove like a truck this one I have now drives like a tank. Every hole or crack in the road I can feel when I hit a small hole or a dip in the pave the vehicle wants to dog track most of the time the truck pulls to the left, when it does there is a slight vibration you can feel from the accelerator or the brake. This vehicle I find is a accident waiting to happen. Its a big vehicle and to swerve side to side scares other vehicles on the highway, which puts everybody at risk everytime I'm on the road. From all these complaints I did to gm still today they tell me and show me paperwork from gm tech line. Stating that everything is normal and no work from there part should be done on this truck. It's like if gm has people working on these statements just to cover themselves from having to repair or change parts in order to save money in which I wouldn't dought. If you can help me please. Let me know cause this is a very serious matter which I would like to fix before I get into an accident. I believe there is a controversy into all of this.

Our son-in-law owns a 2004 GMC 4-door pickup. It has automatic transmission. Our two-year old grandson was in the truck while his father was cleaning it. The key was in the accessory position so they could listen to the radio. The child pulled the shift lever out of park and the truck ran away down an incline. Both driver's side doors were separated from the vehicle by a tree and the truck continued until rear-ending another tree. The child stayed in the vehicle and was unhurt. In checking this truck, our 2003 tahoe, and our 2003 Chevrolet pickup we find that all of them: 1. The shift lever is locked when the key is in the locked position 2. The shift lever is locked when in the "run" or ignition position and requires the brake to be depressed prior to shifting. 3. But in the "accessory" position the shift is completely unlocked and requires only a very slight pressure to move it out of park and result in a runaway. I feel there is no reason for the shift lever not to be locked in all positions and, in fact, the fact it is locked in two positions but not the accessory position results in confusion and a false sense of security. This was not a component failure, but is a design failure that apparently involves all gm trucks and suvs of this model.

I purchased my 2003 GMC Sierra z71 in Aug. 2003. In December 2003, while pulling a travel trailor, the service 4-wd light came on and the truck felt as if it had been shifted into neutral. I managed to get the truck to the side of the road and read the owners manual concerning the light. I turned the truck off as the book said and then restarted. The light stayed on, but the truck did go in gear. Since this time, when I pull the trailor for a long period of time, the truck will again feel as if it is in neutral. I have to put the truck into 2nd or 1st gear to get the transmission to engage. The 4wd light comes on with or without the trailor hooked up and has been checked several times by the dealer. They have replaced the switch but this has not corrected the problem. The transmission shifts so hard it feels as if the back end of the truck will fall out. I was told this is normal operation. Something needs to be done to correct this problem as this is a huge safety issue. No one can feel comfortable driving down a road and never knowing if you will be hit from behind due to this truck stalling for no reason.

We have a 2001 GMC crew cab that we have had for 26 months. Be bought it brand new so we would be less likely to have problems. We have had 3 new transmissions (not including the factory one). It is in the repair shop again because when you put the truck in reverse it dies. Not every time but it happens quite often. It was in the shop before for the same exact problem which resulted in 1 of the 3 new transmissions. Lets hope it doesn't need another one. This is getting old!!!!!!!!!!!.

After driving for about 1 hour on the highway, we exited and came to a stoplight that is when the transmission started shifting hard from first to second gear. When I got home I went on-line and that is when I realized that I am not the only 1997 GMC Sierra owner that has this very same problem, there are literally hundreds if not thousands of us out there with the exact problems with this vehicle. I would like to know if there is a recall being considered at this time?.
