 The passenger side power sliding door does not close properly and opens on its own intermittently. also, once the door is closed the open door chime does not stop. the chime continues to go off while driving, parked and when the car is turned off with the key out of the ignition. this is obviously a safety issue. i tried contacting the dealership where the vehicle was purchased and explained to them the safety hazard defect but was told that they will not fix the problem unless i paid for it. after doing further research, i have found that this is a very common problem for all gm mini vans especially the uplander mini vans, with power sliding doors. however, since there hasn't been an official safety recall, dealerships will not fix the problem without payment. again this is a safety problem and a recall should be issued.

 The lights (interior and exterior) will flicker in my 2005 chevrolet uplander. it has become an unsafe situation as oncoming traffic think that i am flashing my highbeams at them. i have not replaced the voltage regulator yet, but i am sure this is the problem. gm should issue a recall for this item. my car is past the warranty period (60000 miles), and gm will only repair if i pay full price and labor for this safety item. *tr

 This complaint covers many components of the chevy uplander that has spanned over the three years that we have owned the van. all problems are unable to be diagnosed by dealerships and chevy refuses to help us. i have been in contact with chevy from about the second time that the van went to the shop for electrical problems. we have had electrical problems that vary from the lights flickering to the fans output changing to the radio not allowing you to program in a station on one preset button, we are also currently having an abs issue and have had a non gm mechanic look at the van and said it is ok. the passenger side auto sliding door does not always automatically open and sometimes does not close either, when you manually shut it will open by itself several times before it stays shut. we are currently and have for some time had a problem with starting the van this is also something that can't be diagnosed it has been looked at many times. the problems happens about 15-20 times a week. we did purchase the extended warranty on the van and it is now about up and i am at a loss as to what to do because nobody wants to help even though it is clear i am not the only one . please let me know if there is any other way to fight this. the drivers sliding door doesn't always unlock either unless done by hand. *tr

 I purchased a 2005 uplander from a gm dealer in july 2005. i now have 32,167. i took my vehicle in for its normal oil change at 22,000 when the service department said i needed front and brakes and rotors. we replaced the brakes and rotors and my rotors need to replaced again. i also noticed a noise coming from the left front tire i was told that they did not hear the noise and everything was fine. i have taken the van in for dimming on the lights and the vehicle feeling like it is going to stall too many times to count and every time they tell me it is just the way gm vehicles run. i also have a problem with the starter i will crank it and nothing this happens at lease once a day and i have to retry at least two times before the van will start.the steering has been a big issue we have been having problems with the tightness and when i am driving i can feel the back end swaying. the vehicle is unsafe to be driving and with two small children it is extremely scary. after reading all the complaints how is this vehicle still on the road. the issues people are having are extremely dangerous. the dealership i go to has never tried to fix or replace any of the issues with my van. they also tell me its normal and they cannot find anything wrong. i am looking to replace the tires they are bald which is causing the van to hydroplane everytime it rains. the sticker on the inside panel is different from the tires. the tire goodyear intergrity p225/60r17 states 44 psi with a max load of 1653 lbs. the inside sticker states 35 psi and max load of 1330 lbs. the tire size is extremely hard to find. i have also noticed when we close the sliding doors they do not shut, the latch doesnt catch the door until you slam extremely hard. then my daughter will try to get out of the vehicle and the child lock will be on when we didn't slide it on. can someone please do something to stop this

 We have had several issues with the doors not closing and have taken the vehicle in several times. the service dept. couldn't duplicate the problem. apparently gm knows about the problem because the last time we were in there they told us there was an internal service bulletin about re-routing wires and possible module replacement, all of which was done to our vehicle. it is going back in again 7-27-07 for the same problem. our uplander also has a problem of the door locks rapidly locking and unlocking at various times while driving, and all of the lights will flicker and dim. one instance while driving at night all lights went out briefly and came back on, extremely dangerous! something has to be done. we live in michigan, you'd think there wouldn't be a problem in the motor city. *jb

 Dt*: the contact stated while driving the head lights and the interior lights started flickering. the first time the vehicle was taken to the dealership, it only had two hundred and thirty eight miles on it. upon inspection, the dealership determined the module computer control body needed to be replaced and the instrument panel was reprogrammed. even though repairs were made, the vehicle was still experiencing the same type of problems. when the vehicle was taken to the dealership a second time, the sensor in the running day lights and the generator assembly were replaced. after driving the vehicle for a short period of time, the head lights and interior lights began flickering again. the vehicle was taken back to the dealership however there were no repairs made. the manufacturer was alerted.

 My wife had driven from our home 7 miles away to the maggie moo's ice cream shop. she went in to the store to purchase some ice cream for my kids and her mom who stayed in the vehicle which was left running because of the heat. when she returned she backed the vehicle up with no problem but when she attempted to pull forward she heard the wrongest noise emanate from the front of the vehicle she has ever heard and the vehicle jumped and bumped and came to a grinding halt. i did not think it could have been so bad as she explained to me when i arrived. so i backed the vehicle out of the parking space that she managed to get to and pulled forward. oh my god! what she had explained to me wasn't even as bad as i experienced. the stability control activation message appeared in the dash display and the antilock brakes on the driver side front wheel began to growl then screeched the vehicle to a grinding halt. i was scared. my kids were thrown around in the car since they had unbuckled their seat belts while eating their ice cream. i made them buckle up and i tried it again. the same result over and over again until i finally got to a parking space. i called chevrolet to come tow the vehicle in to repair my 2005 uplander. they called me the next day and informed me that they found no problem and that the error codes pulled from the computer showed not error ever happened. this scares the hell out of me and my wife refuses to drive the vehicle. our fear of this malfunction occurring at highway speeds could result in catastrophic results. i am in contact with gm but they are so far unwilling to admit or take any action to resolve this safety issue. i need help!!! we all need to know if there is a major problem with the stabilitrak system being deployed on these new vehicles. please take this up and open an immediate investigation. i am documenting this malfunction everywhere i can think to because no one needs to die because of a defect. *nm

 We were taking vacation last december going thru the mountains and it was very foggy. you could barely see the road and we noticed the headlights and interior lights were flickering. the following week i took it to my dealership to let them fix the problem they did let me know that they were aware of a problem. they showed me a paper stating that gmac was trying to correct the problem. this was last december and it is now june and still no solution. this could cause a accident especially when you are driving in foggy weather. i really hope someone can find a the solution to the problem or i might just take the vehicle to the dealer parking lot and park it until the solution is fixed.

 Dt*: the contact stated while driving in normal conditions, the electrical system does not properly work. this occurs at various speeds. while the accelerator pedal is depressed no problems are apparent. however, when the accelerator pedal is not depressed the heater blower does not blow and the exterior and interior lighting is so dim that the contact has visual problems while driving at night. the vehicle was taken to the local dealership numerous times for inspection and repairs. the dealer replaced the alternator although that did not remedy the problem. the dealer can not duplicate the problem; therefore no additional repairs were made.

 I have had to jump start my 2005 chevrolet uplander several times. the car has been taken to the dealership three times (today 2-21-2008 being the third). the battery was replaced once, the radio was replaced the second time. i have not received a diagnoses to the problem today, but the vehicle would not start even with a jump from a tow truck. the only item installed after market on this vehicle was a sit and lift seat, installed by the dealership at a cost of $5000. the seat has performed without failure, other than a few times it would not operate unless the side sliding door on the opposite side of the vehicle was opened or closed, depending on it status at the time of the failure. *tr

 The car intermittently tries to start the crank keeps turning but does not start. as well as i was traveling on freeway with a big rig on the side of me and the car stalled and steering locked. thank god i managed to glide over to the exit lane. i was terrified as was my passenger. when i looked at the gauges i noticed i was out of gas, but i had just put in $20 . chevy sent out tow truck to give me gas, but car still would not start. finally hours later car was taken to chevy. when uplander was finished they said it was electrical short due to water in lines. weather was great no rain or puddles anywhere. uplander almost stalled on another night lights dimmed and tires stopped ,but then it worked fine. strange very!!! driver side sliding door opens or shuts when it wants. my daughter was in her car seat and i pushed button to close door she put her foot up towards door and it shut and locked. luckily her tennis shoes were a little big so only minor bruising occurred. however my daughter is terrified of car. also i have already put 6 new tires on car because they were bald at 13,000 miles first time. tires in front are bald again. uplander is not stable to drive on highway. *tr
