Service Brakes Problems of GMC Envoy - part 1

I purchased my Envoy from a used car lot with no warning lights and no apparent safety concerns about 2 yrs ago other then what appeared to be a replaced front bumper cover and the vehicle was repainted the same color white, since then the brakes have intermittently not disengaged on one side or the other I believe it's the front brakes and seems to be worse after a longer drives and after bleeding the system the pedal would be firm and next day spongy feeling and going down rather far. Air bags did not deploy apon impact. It is available for inspiration although I am attempting to repair it after my accident the brakes are still as they were. I have tried both on as well as performance pads and rotors booster check valve and fluid replacement with no change. I was coming back from my daughter's dentist appointment it is 20 minutes away the roads were very slick with snow and sleet, I got off the hwy and coming through town I braked to slow from 45 to 35mph before crossing the intersection when I let off the brake the left side stayed engaged enough to cause the vehicle to pull to the left and I couldn't steer straight because of the snow and was forced to hit 2 traffic light posts in the center median. Usually on dry roads I can tap the pedal and keep it straight until the brakes released. I first noticed it changing pads when I 1st purchased it that the front tires spin harder while jaked up and when it continued I figured it was alignment or steering components worn but even after parts replaced a 2 alignments nothing changed, after my last alignment the technician said the brakes need to be bled and I told him the issue he was unsure the cause. I did not have any air bags deploy in this accident and the sensors were clearly effected as the bumper caved in the center. The vehicle also has had uneven ride height due to independent sensors in the rear. The vehicle now has a service airbag and service brakes light. Other owners have similar issues with their Envoys.

All the gages have stopped working correctly. They do not report proper information to driver . The electrical wiring to the rear wiper, license plate lights and rear hatch stopped working. The most dangerous thing is the abs brake system dash lights and bell comes on every time the car is driven and the brake pedal goes to the floor when trying to stop.

My spouse was driving down s/b on rt 313 @ rt 290 maryland. He hit a deer and rolled my Envoy and the air bags never deployed. My son was in front passager set with a set belt on and when the Envoy rolled his set belt did not hold him on. My spouse told me the anit-lock breaks did not engage when he slam on the breaks .

Driving car brakes go get it fix paid 375 to get fix now no power steering fuel gauge dosen. T work what a mess need help.

This is a very unsafe vehicle. I purchased it for my husband and have seldom drove until recently when he was injured driving it. He drove through our garage and demolished it. I how drive it and find the brake and gas pedals the worst problem. No matter what shoes or boots you are wearing you cannot control the vehicle. It has cost us thousands in damage and repairs. I do not have pictures, but will obtain them and forward them. The car was just pulling up to be parked outside by out garage when the problem occured. The weather was fine-August 2017. It was just getting dark. This vehicle should be taken off the road ASAP until it is repaired or replaced by GMC. My son drives a used GMC and it has none of these problems. The picture I am sending you is of jack benjamin blazek, a technician at bretting manufacturing, inc. In ashland. Ben has also built dirt track race cars and I have built john deere combines.

While driving on a city street the car started lugging and not driving smoothly. When I needed to brake shortly after this happened the brake pedal went to the floor and I had no brakes. I pumped the brakes and was able to stop without hitting any one. I continued about 5 miles continually pumping the brakes not knowing if they would work . During this time the pedal would sometimes go to the floor and other times almost go to the floor. Then as suddenly as it started it stopped. Brakes were back to normal. This happened previously and the GMC mechanic found nothing wrong. So I'm put back on the street risking my life and someone else's because the mechanic said "it sometimes happens". That's not acceptable!.

I was stopped at a light when the car accelerated on its own, I pressed the brake but the car would not stop . I hit car the car in front of me, I had to put car in neutral to stop the car. Car was towed to dealer, the cause was a internally shorted throttle body. The throttle body was replaced. This was the third time car accelerated on own and would not stop. The first two times my mechanic could not find any problem.

Tl the contact owns a 2007 GMC Envoy. While driving various speeds, the service stabilitrak warning indicator periodically illuminated. Also, the stabilitrak active indicator periodically illuminated, which caused the vehicle to stall. When the contact released and re-applied the accelerator pedal, the stabilitrak deactivated and the vehicle functioned normally. Occasionally, when the brake pedal was depressed, the brake pedal vibrated violently and the vehicle hesitated to stop. When the vehicle was stationary and the brake pedal was depressed, the vehicle accelerated forward. Furthermore, the driver's seat was unable to move forward. When attempting to adjust the seat manually or with the power position adjuster, the seat failed to adjust until after a period of time. The vehicle was taken to bowser Buick GMC (1001 clairton blvd, pleasant hills, PA 15236, (412) 346-7929) where the contact was informed that the driver's door module needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failures. The failure mileage was 90,000.

"takata recall" when I first start the car and begin to accelerate the traction control system activates causing lose of power - very dangerous when pulling out into traffic. I have to disengage the system on the shift handle to prevent this from happening. I am also experiencing the abs problem of activation when coming to a stop in all conditions. It is already a recall for GMC vehicles up to 2004 but obviously not corrected. The traction control system activates every time after first starting the car. The abs system is sporatic. No warning that it is about to happen. These systems fail daily without exception.

Abs activates for no reason. It happens at slow speeds when I am coming to a stop. It happens all the time.

The contact owns a 2003 GMC Envoy. While driving approximately 5 mph, the brake pedal vibrated and hesitated to respond when depressed. In addition, the brake pedal felt abnormally soft when applied, which required a longer stopping distance. The failure became progressively worse. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 60,000.

Nothing but this has been nothing but trouble since I bought for that dealership. Guy from todd wenzel grand rapids michigan.

Accelerating while entering a freeway, took foot off the gas and the vehicle continued to accelerate. Applied brake but vehicle continued to accelerate. Put vehicle in neutral to try and slow down and again applied brake. Vehicle began to spin to the right and we hit the guard rail, hitting the passenger rear bumper and the driver's side front bumper. Side air bags deployed. Car spun into the middle travel lane and began to spin around. Car was slowing down and was able to turn car off. Fortunately no other cars were involved. An off duty sheriff's deputy stopped and said he noticed smoke and thought the car was on fire but no fire occurred. When state police arrived they asked us to move the car to the break down lane. Was able to put car in reverse and backed car to breakdown lane. Tried to put car in drive but car wouldn't go forward.

I was pulling up to park in a parking lot. I had total break failure. The electronic safety features failed- and there was no stopping the Envoy. I slid up the curb and into the building. The mechanic that repaired the Envoy has a written report of the safety systems getting stuck half opened and the break lines breaking and there wasn't any fluid in system.

When I went out to start my car it wouldn't start so I took the key and my dad my be I need a jump he said no if that was the case the car wouldn't even turn over. I went back out to try it again but still nothing sio I began to turn the key back and fourth and eventually it stared. A few minutes the cigarette outlet caught on fire so I unplugged my car charger.

The contact owned a 2006 GMC Envoy xl 370. The contact stated that the abs warning lamp illuminated, which indicated a malfunction. The vehicle was taken to the authorized dealer, but they were unable to replicate or diagnose the failure. The contact also indicated that there was a noise emitting from the front of the vehicle associated with the wheel hubs and they were not able to diagnose the failure. The vehicle was taken to a repair shop. The mechanic indicated that the driver side wheel hub was defective and that both front wheel hubs needed to be replaced. The dealer did not remedy the failure with the wheel hubs. In addition, the low beam headlights failed to work. The contact received notification of NHTSA campaign numbers: 13v248000 (electrical system, visibility) and 14v755000 (exterior lighting); however, the parts needed were not available for several months. While traveling over 70 mph, the front two wheels fractured without warning and the driver was ejected from the vehicle. The frontal air bags failed to deploy. The driver received medical assistance, but sustained fatal injuries. A police report was filed. The manufacturer was notified of the failure and provided no remedy. The vehicle was destroyed. The approximate failure mileage was 117,000.

On 12/23/13, while parked the vehicle died. When restarting, it was a little slow but did end up starting. On 12/24/13, I had the battery tested and it showed that the cca's just needed a good charge so I let the vehicle run for 45 minutes. A few hours later, the vehicle would not even turn over. On 12/25/13, removed the battery and reinstalled it. The vehicle started fine and ran well for a few days. On 1/1/14, vehicle stalled while driving. Ended up restarting but I had to give it gas to do so. On 1/2/14, I started the car to warm it up and it started fine. I let it run for 20-30 minutes before attempting to drive it. When I got in the vehicle, it said that the brake system was not working and the stabilitrack light was flashing on and off intermittently. I had to get a cab to work & have it towed to the shop. I'm hoping to hear back tomorrow in regards to what is going on. Also, had to get a rental vehicle in the meantime for transportation.

Upon shifting tranny into park gear vhecile continued to roll forward or backward note : upon pushing in shifter relaese button shifter engaed in park gear however indicator displayed drive internal failure cable broken and emergency brake did not work so I had my neigbor put bricks behind the rear wheels all the while the car shut itself off and the steering wheel locked.

Some times when the brakes are applied the throttle also advances causing unwanted acceleration. Happens at low speeds. Have there been any factory recalls for this problem?.

Driving at approx. 2:30 pm in intermittently rainy conditions- I suddenly found myself unable to control my vehicle and had trouble seeing my surroundings even though I had new rain-x wipers on. While I applied the brakes they did not work as effectively as they should. Additionally, after the first and second impact (multiple vehicles were involved)- no air bags deployed. I was the only person in the vehicle and still the drivers side air bag did not deploy. Resulted in two fatalities in another vehicle while I suffered a head injury, facial fractures that required surgery, and a broken collar bone from the seat belt that I could not afford the medical intervention required for repair.

I have owned a GMC all my adult life. This Envoy has been nothing but problems . . . . Now the gauges seem to be all screwed up and after reading post from online. . I will need to put more time and more money into this SUV. Nothing like driving late at night worried about what's happening now. I go from sitting at a red light and my car losing pressure and turning off, to now every time I get into it and leave my house I hear the door bell and all my panels symbols flash and shows no gas to no battery life. . I am not pleased and will never purchase a gm again. . So sad.

The SUV has shut off on me three times in the last 2 1/2 yrs (the time I have owned it. ) each time I was just driving on the city streets going about 30 mph. All of a sudden the car just shut off and all lights, etc just turned off. I am concerned wondering if perhaps there is a problem with the 2005 Envoy ignition switch as well? no, it was not the battery or anything to do with the servicing of the SUV. I take care of the vechicle and I don't drive 200 miles a month. I guess I am lucky that each time I was not gong fast and the SUV just slowed down and came to a stop, on the side of the road. However the 2nd time, I had 2 little girls in the car with me and it concerned me a great deal. Each time the SUV started back up and I was able to resume driving after about 2 minutes. What if I had been going faster ? what if I had been on a highway etc. If there is an issue with the ignition, please lets fix it before someone dies. I will make sure everyone in my family know about the shut off problems I have had with the car. Just in case something happens while I am driving it.

While driving around town, I hear a noise, that sounded like a flat. The truck began to slow down on its own, without me applying the breakes. I managed to get the truck over to the side of the road. The service stabltrk light wa on, the brakes locked up. I had it towed to the dealer who did 1400 dollars of work on it , but stated the could not get it to duplicate my complaint. 7 days later it repeated the same thing, I had it towed to the dealer. This time they told me that I had contaminated brake fluid. I was upset, and felt I was bing jerked around. I had it towed home. Had another machanic test the brake fluid, needless to say, it showed to have the normal amount of contamination from routine driving. He also could not get it to repeat the problem, I am assuming no codes came up this time either. I have drivien it for one month with out a problem, untill this morning, I went to the store, about 1/2 mile from my home, and the same problem occured. After leaving the engine off for appro. 30 min, it became drivable again.

I was traveling north on the FL tpke. In my 2006 GMC Envoy on 11/8/11 just south of orlando at 9:30 pm when the car in front of me jammed on the breaks because the car in front of him was driving unsafely. When I jammed on my breaks the abs did not function and the breaks locked up. I was swerving violently from side to side across the two lane highway until I finally got the vehicle under control with much physical effort. I thought I was a dead man but I survived. Thank god there were no other cars around me or there would have been a terrible accident at 70 mph which is the speed limit. Luckily I was able to avoid striking the other two vehicles in the road. There was tire smoke everywhere. This is a serious problem and now I am afraid to drive my vehicle at highway speeds. GMC needs to be notified and something needs to be done about this.

The front brake shoes on an 2004 Envoy has been replaced every year since 2007. Will not wear evenly and causes the front end to vibrate when applying the brakes.

2005 GMC Envoy brakes locked up which caused driver to spin off the roadway striking a guardrail. (ohio traffic crash report # 10-0146-90) updated 05/13/10.

At 38,000 miles on the my SUV my gauge stoped working, and ran out of gas two times. I'v had to keep an eye on how many mile I drive and fill it up every 250-300 miles. Also I'v noticed that sometimes my brake pedel stalls for a quick second. I love my vehicle but very disappointment in the problem it has in its early years and to find out the there are hunders if not thousands of people that have this same problem and gm wont issue a recall on there vehicls. It is very unsafe to dive not knowing how muck gas you still have in the tank.

The brakes on our GMC Envoy "skip" when there is wet weather, bumpy roads and especially snow. When trying to brake, the brakes don't seem to grab and it takes extra long to stop. We haven't had any crashes, but several close calls due to the brakes not engaging. In dry and normal weather, they work fine.

2005 GMC Envoy. Coming to a stop, put foot on brake pedal, foot slipped off, car continued moving into passing car. This also happened July , 2009 but with more damage. Prior to these incidents, had several times when feet slipped. [2 different drivers] pedal is either wrong size, material, or placed in wrong place. Afraid to drive it now, it is parked in garage. Your form does not allow for "brake pedal" . I marked service brakes, but it wasn't the brakes.

Brakelight molding above rear liftgate/window flew off on highway for unknown cause in 2/08. 6/09 - rear liftgate/window shattered upon opening liftgate - brakelight molding off again.
