I recently experienced a known electrical issue for the first time yesterday. I just had my Tahoe at the dealer last week for strange clacking noise under the hood. They stated I would just have to wait until it did it again. Yesterday everything went haywire and my Tahoe appeared possessed. Door locks, gearing shifting was affected making it difficult to drive and steer due to loss of power steering, which could have caused serious risk to others around me and my two children in the car. Turning to the internet and finding that I am one of what is probably thousands complaining of the same issue makes my extremely concerned that GM is not looking out for its current and future customers. I will be filing a complaint with the attorney general's office, ntsb and now with the state of nc immediately. Not only have we dealt with this issue. We have long dealt with the oil consumption issue that GM continues to say is "normal" consumption. Extremely disappointed in GM and how they are handling major component issues. We also own a Jeep Wrangler and they are been absolutely amazing anytime we have an addressable issue.

Went to dinner and drove home with no indication of any problems. Pulled up to a stop sign, stopped and began to drive forward. Suddenly we heard a loud bang, the RPM's raced to 4K and the vehicle was stuck sitting at the stop sign. No drive, or 3rd. We were able to move it in reverse and slightly in 2nd but had to strain up hill to get our car and kids home in the dark in 1st gear. Got home and checked my transmission fluid because it had been flushed 14K miles ago and I wanted to make sure there was a proper amount of fluid in the transmission not causing this issue. Transmission fluid was pink, clean and measured where it should on the dipstick. I researched transmission problems on the internet in which people had the same no forward movement in 3 or 4 but 1, 2 and rev. Ok. found out that there is an issue that thousands of people are having with the 4L60E transmission that GM has produced due to a faulty forward sprag component that was built with cheap stamped metal and they released a tsb pertaining to an updated component! I do not tow anything with Tahoe and have made it to 113K miles on my transmission. Im being challenged to provide records of my transmission service being done. I have worked for a car dealer as a service advisor for 10+ years and have always purchased all of my parts from a GM dealer to ensure my vehicle would run and drive properly. I am fortunate enough though to not have to pay the dealership labor rate as I have one of my technician to perform my services regularly. I just purchased fluid from our GM dealer and had a complete trans flush at 100K miles like recommended by GM. It has been a problem since 2008 and vehicles affected by this causing a tsb release were not due for trans service yet! it is evident that this problem is not due to lack of maintenance but from poor quality parts that GM claims are built to last! junk!

My wife was accelerating from our street onto a major highway when the engine nearly shut down. Her speed was reduced to just 5 mph and the dashboard flashed engine power reduced, service stabilitrak, and service traction control. Unfortunately, she knew exactly what this was since this is the third time this has happened in this car in the last 18! we took it to our dealer and they tested the vehicle and diagnosed that the accelerator pedal sensor had failed again! we are extremely uneasy with the car now since each time this has occurred, it has been while one of us was accelerating onto a highway or interstate. On the previous occasion, she had to quickly move away from oncoming traffic...with our children in the car. The dealer indicated that they see this problem very often, but not this much in one car. This is obviously a defective part and should be checked into immediately.

After driving approx 3 miles, my "stabilitrak off", "traction control off", ABS light, check engine light all came on, simultaneously. My speedometer and other gauges started swinging from left to right and then flatlined, my power locks, "locked and unlocked". when the transmission shifted, the whole Tahoe jerked. When I arrived at my destination approx 3 miles further and turned the engine off, attempted to re start and it wont start. This is the fourth time this has happened in two weeks. I have taken to a Chevy dealer twice to diagnose. Both times they said they cannot find the cause, and all they can do is reset the error codes.

My vehicle is experiencing excessive oil consumption due to the active fuel management(displacement on demand) feature. The vehicle consumes approximately 1quart every 1000 miles...the oil is burned through the pistons causing blue-ish colored smoke to come out of the tail pipe. The vehicle comes not a drop of oil if the active fuel management is turned off. Every single vehicle from GM that I have tested has had excessive oil consumption due to the active fuel management feature. After that feature is turned off, no oil is consumed. 1 quart of oil is burned is as little as 300 miles. This can cause the vehicle's engine to shut off at any rate of speed due to the oil pressure caused by not having enough oil in the engine. General Motors has tried fixing my vehicle and others by replacing the lifters, camshaft, pistons, piston rings, etc..this fix has not worked and many vehicles continue to have excessive oil consumption. Vehicles affected range from year 2007 and up (present). My vehicle also has various transmission issues which causes the vehicle to shut down in the middle of my driving and greatly increasing the risk of an accident. General Motors has had various repairs but have been unsuccessful. This is a problem for GM SUV's with the 4-speed transmission. The oil consumption issue is way more serious than the transmission problem because many people have been affected more by the oil consumption problem. Excessive oil consumption also damages the earth's environment because of the excessive smoke coming from the tailpipes.

The contact owns a 2007 Chevrolet Tahoe. While parked, the contact was unable to place the gear shifter into drive. The contact was only able to place the vehicle in reverse. Previously, the contact noticed that while accelerating, the RPM reading would increase dramatically. The vehicle was not taken to the dealer for a diagnostic test. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 50,000.

I was at a stop light, and the problem happened unexpectedly when I pressed on the gas when the light turned green. My car moved forward just slightly, jerked hard to a complete stop, and it wouldn't drive anymore. I was able to get pushed to the side in neutral, but needed a tow to the dealer. The only working gears were R, 3, 2, and 1. bringing it into the dealer, they confirmed there was a problem with the transmission. I had done some research when this happened and noticed that a lot of people had the same problem, all in the same type of scenario where they were at a complete stop. Second issue, not nearly as major is the stabilitrak. The light goes on and off constantly, pretty much from the first year I've had the car. And lastly, the interior chrome door handles have all peeled off and cut me and my passengers several times. The exterior door handles have come loose, the fuel pocket is completely broken, and after a heavy rain, water gets trapped inside the shell of the back door and sloshes around while I'm driving. I have to remove the bottom lining of the door for the trapped water to be released.

Truck rolls back when on incline even while in park, and it does not stop, I also noted truck would not go into V$ mode and was shifting a little rough in lower gears. July of 2008 took to bob stall Chevrolet for oil change and asked for it to be checked (as well as power system) returned to pick up my vehicle and they insisted tranny was fine as there were no error codes. I mentioned power issue and they claimed to not have time to test (they had the truck all day, it was also not on the roll) unsatisfied I returned again with the truck for another issue (moldings) and asked for it to be tested. Received my truck at end of day with moldings fixed but only an assurance my transmission was fine and all was normal, not even mention off battery problem. I returned then a third time to dealer and had to insist they drive the truck and full test transmission. After having my truck a full day I finally was informed that yes my tranny had a problem. Their tranny tech drove it and noted the problem in lower gears and after inspection (opened up transmission) discovered burnt bands. My transmission was rebuilt with 2 clutch packs replaced. Issue of roll back was claimed to be normal. It took several attempts for this issue to be taken care of and I feel the diversion wa sintentional.. a few more miles.. out of warranty.. poof they would have kindly discovered problem then charged me for it. I have also heard of several others with transmission issues and suspect a design or assembly flaw.

Vehicle will accelerate and max out at fuel cut-off. Acceleration is unresponsive to brake application to include 100% application, resulting in smoke and odor. Vehicle cannot be stopped other than placing the vehicle into neutral and turning the ignition off. Upon restarting the vehicle, RPM will immediately climb to in excess of 5000 RPM. Acceleration problems normally occur at higher speeds but have occurred also on city streets. The problem then resets itself at its discretion. Cheverolet has been "working" on finding the problem since September, total in excess of 90 days. I was provided with a vehicle data recorder (vdr) to image the issue. Vdr has a cable plugged into vehicle computer the dangles between the gas/brake pedal and driver posing an additional hazard. Vehicle is an extreme safety hazard likely to result in great bodily injury and/or death. I am unable to and have been unable to enjoy and utilize the vehicle for the purposes to which it was intended for/purchased and have been placed in a severely risky position by Chevrolet. In addition, control of the vehicle in inclement weather has been compromised due to failure of the stabilitrac where it engages and disengages without application of the button. This issue has also been raised with Chevrolet but no codes were read due to the vehicle being turned off, causing a reset (per Chevrolet). However, when stabilitrac problem surfaced yet again, problem was witnessed by Chevrolet service rep but no work could be done due to an open ticket with GMC regarding the acceleration issue. Chevrolet has downloaded images/information from the vdr and has stated that there is/are issues and reset and returned the vdr to me requesting again that I take more images when my vehicle is stuck in acceleration and to be careful. Initial attempt for this repair in September noted "drivable concern." Problem is recurring from 0-9 incidents each day. I am concerned for the safety of others as well as myself.

I have a brand new 2007 Chevy Tahoe, the car was driving normal, I was heading to the on ramp of the freeway, but to get into the freeway I had to make a right and then the on ramp is in front of me. Of course you also had cars coming from the right of me. When I saw a gap where I could go, I floored the gas, to go into the freeway, when I heard a loud noise, and all of the sudden the car slowed down. I had to think quick being that the car was an automatic, I shifted to a lower gear, the car started moving but it was making a grinding noise. I finally got out of the way. And I called onstar, my transmission had given. On a 6 month old 2007 Tahoe. They took it to the dealer, at the dealership they replaced a gear inside the transmission, to no avail. Finally they ended up replacing the whole transmission, because they couldn't figure what was wrong the car. No warning lights or nothing. The guy at the dealership told me, that this was so weird that the techs in Michigan wanted the whole transmission shipped to them. They had the SUV for a total of 21 days.
