| Electronic Stability Control problems |
Service airbag, service traction control and service stabilitrac pop up on the driver information center screen randomly and go away randomly. I have noticed the airbag warning happens more frequently when the roads are wet. Vehicle was just at dealer for service and they couldn't find the problem.
When driving on dry pavement the traction control or stabilitrak will kick on and it pulls to the right really hard on and off and its hard to control the vehicle. The first time it happened I actually thought I had a flat tire. When this is happening it feels like the anti-lock brakes also kick in as it is very hard to stop also. I have had this happen at 45mph and its terrifying im afraid if this happened at 70mph it would cause you to lose control of the vehicle.
Vehicle goes into engine reduced speed and service traction control and service stabili track warning lights turn on. I have had this problem starting a week after I purchased my van and was "repaired" on numerous occasions and the problem keeps reoccurring. The incidents happen while driving and when stationary while engine was running. The dealer replaced the accelerator petal assembly a couple of times and also replaced the throttle body position sensor and the problem still continues. The last time I took it in the dealer put dielectric in the harness and said I might have a moisture problem. The problem reoccurred again a few weeks later. I don't see how moisture could be the problem since it started a week after purchase and continues 4 years later.
Driving down a hill at 30 mph on a one lane curve the vehicle completely quit. I struggled to turn the wheel to the side of the road. It had 3/4 tank of fuel and only 7,000 miles on it. It would not start. Called and got a tow to chevy dealer where it was bought. They could not duplicate it. Have receipt and info from them.
I bought a Chevrolet van Express with a 6. 0 v8 engine a year ago with only 37000 miles. Approximately 2 months after purchase, I began having trouble with the engine and stabilitrak system in addition to the low beam headlight failure detailed below same across the entire v8 6. 0 engines produced by Chevrolet. The van vehicle shook violently stressing all the occupants. While traveling on the highway my check engine and traction light illuminated simultaneously. I was also alerted that "engine power was reduced" and my vehicle shut down two times in a 30 minute span of time. Now with only 41,000 miles I have parked the van until a recall corrects the dangerous safety problems. Again while traveling on the highway my air bag sensor went off with the check engine and traction light again illuminated simultaneously. The van vehicle shook violently stressing all the occupants. I was alerted that "engine power was reduced" and my vehicle stopped cold. I will never buy another gm product they are fraught with electrical problems. This is causing safety issues being in a compromising position 3 times with 9 people and 2 are infants in the van. Research shows this to be an ongoing issue. This has been a nightmare. Something as dramatic as a total engine failure in a car that is as popular as the v8 6. 0 engine is a frightening issue that everyone across the industry is going to want to know more about. F the engine won¿t restart . Tthe steering will feel increasingly heavier, making it harder to steer. Also the power boost for the brakes disappears after one or two applications, making the van harder to stop. In the affected vehicles, the underhood bussed electrical center (ubec) housing can expand and cause the headlamp low beam relay control circuit wire to bend. If the wire is repeatedly bent, it may fracture causing a loss of low beam headlamp illumination.
The vehicle randomly and autonomously applies the brakes and cuts engine power while driving. At this time the vehicle states "service stabilitrak" and the icon flashes that I am skidding, which I am not (I have video proof of this occuring). After 4 trips to the dealership the problem still persists. It is only a matter of time for this to occur while merging, or making a left across traffic and cause a serious and potentially fatal collision.
While driving down the road at approximately 50 mph all warning lights on the dash lit up, the speedometer ceased to function, the radio cut out, the airbags were reporting as nonfunctional, the abs system was reporting nonfunctional. Took vehicle to local mechanic who said the problem appeared to be caused by corrosion on the abs sensor as well as corrosion on the power distribution cables into the fuse box. According to the mechanic gm was aware of the problem, as technical bulletins dating back to around 2005 were issued. He also stated should it happen at the time of an accident the air bags would likely fail to deploy, and the problem in general could lead to the possibility of a vehicle fire. According to him the entire problem could have been avoided by the manufacturer if they had made sure the cables were wrapped in shrink tube-thus eliminating the introduction of moisture to the electrical wires.
On October 23, 2012 at 3:00 pm the van pulled to the right while in a left turn, steering first to the right and then to the left when brakes were applied. Van speed was about 25-30 mph, driver was able to control steering but only with force. Light for stability control came on as steering control was lost and was off when van stopped. Engine rpm followed gas pedal lift, and brake apply. The van went onto the gravellecd shoulder of the road during this incident.
An operator reported in August of 2012 that "the engine dies after driving about 1 mile, then restarts. " in September 2012 we had one operator document his finding over a two week period, his reports include: "9/14/12 left brake pull, going straight at 50 mph after about 1 to 2 miles of operation. " "9/10/12 front brakes seemed to come on, speed dropped about 15 mph from 55 mph, this was within the first 4-5 miles traveled. " "9/12/12 van pulled to right, right brake came on while going around a left hand corner , speed dropped 10 - 15 mph. " 9/17/12 brales seemed to come on after 2 - 3 miles. " "9/20/2012 right brake pull while leaving driveway of service center, making a right hand turn. " all incidents occurred in the morning within the first 5 miles of operation, the operator was the only person in the vehicle and no dash or warning lights came on.
This vehicle has had multiple incidents of cutting out and stalling causing loss of steering and brakes, and just before it completely shuts down it will power back up. In April 2011 an operator stated "intermittently when making a left hand turn at approx. 10 - 15 mph with acceleration the traction light comes on and van cuts out for a few seconds like someone shut off the key, it powers most of the way down and then will come back on its own. " during this time the steering and brakes are compromised. In November 2011 an operator stated "powers down while operating, brakes lock up and power steering locks up, van pulls to the right in corners, seems to be abs with no brakes applied in corners/" in November 2012 it was reported from 3 different operators that the van cut out and each of them almost lost control of the vehicle. Reports included going 40-45 mph into a left hand curve, the engine suddenly started to lose power and there was a loss of steering and brakes, and the right hand tire went into the ditch on the right. Another operator said the engine died and the vehicle almost went into the ditch, the vehicle was cold and they had just begun their trip. The 3rd operator said the wheel locked up at 40 mph within the first 1/2 mile. Most of these incidents seem to happen within the first 3 miles of operation.
