2007 Chevrolet Tahoe: sudden loss of power

Filed Nov 26, 2024 · Acceleration · MO

Service Stabiltrak error and service traction control error. Reduced engine power error causes the motor to completely shut down with no warning even while driving making it impossible to get out of traffic and to safely exit to the shoulder. No acceleration when pressing gas pedal.

Our car doesn't even have 100k miles and lost all power while driving to the speedometer as well as radio, lights, etc... We even took it to a mechanic who is also having troubles figuring it out. Paid over $500 to have them change the bcm and ignition switch still having issues to the point it will not start.

I have been dealing with the same problem as the previous complaint...ironically, my vehicle was manufactured in tx too, but, I purchased it used in va in 2011 odometer-73,625. To date, I only have 101,225- I started having constant stabilitrack/traction control issues right after 100,000- caused steering wheel to lock up and loss of power in addition to door locks suddenly locking/unlocking, car alarm going off, and hazard blinkers not working (all while in the middle of rush hour traffic)! After this constant issue was "repaired"-for 6th time, a few months later, I experienced a different problem. After waiting at a stop light, the vehicle would not accelerate-I had to push gas all the way to the floor, barely reaching 20mph, then, the car started shaking & to make matters worse, the brakes were barely working. Thankfully, I was near a parking lot & was able to pull over. This time I think it is a bcm or pcs issue. It seems the "flex-fuel" 4wd 2007 tahoes are having major issues. This should be constitute under lemon law. I am too scared to drive now-the car has been sitting in my driveway for a long time, yet I have to pay insurance & registration. I'm sick of wasting money as well. Please help us (2007 tahoe owners), fix these issues! Thank you.

My 07 tahoe has been having stabilitrak and traction control on for months I've thrown several different parts at my tahoe it'll work great for a day or two then the codes pop right back on my dashboard causing the steering wheel to lock up and the truck to lose engine power and jerk around while driving. This is a serious issue I've had to be towed home , change several parts and can get no answers as to why it keeps coming up. Please please please recall it for this issue I have seen many complaints about the same thing for the stabilitrak and traction control to keep coming on and not knowing why please gm yall are the best and need to fix it!!!!!!! Very tired of throwing money away!!

While driving the vehicle the stab trac warning pops up on the message window and we lose power. We have had it to the garage for the same problem multiple times and we have replaced multiple different things and it keeps coming back. As per online records of this vehicle it appears shelby does not know how to fix it either. I'm tired of just throwing parts at it and want to fix it permanently. Every time this problem occurs in a while we are driving at at least above species of 40 miles an hour and to be honest it's more of a safety hazard because it goes into limp mode and then you can only go 10 to 15 MPH.

While driving my 2007 chev tahoe today, while in motion, the stabilitrak warning came up on my dash along with traction control warning. Then the engine started struggling. I googled these problems and it appears gm recalled models from 2014 and 2015 with the same issues. They need to recall all impacted models. If this causes the engine to lose power, it could cause a dangerous situation.

While driving or idling, vehicle displays error messages stating "reduced engine power", "stabilitrak system disabled" and "service traction control." the engine power reduces and the vehicle hesitates upon acceleration. It is difficult to get the vehicle to accelerate, especially in lower gears. Sometimes the vehicle completely loses power in the middle of driving and all control of the vehicle is lost. This has occurred both on city streets and major highways. Purchased the vehicle used about 5 months ago and it began doing this at after about two weeks of ownership. Took it to a chevrolet dealership and they said the throttle body was sticking and needed to be replaced. The problem seems to be getting worse over the last few weeks. The vehicle is now stalling on a regular basis (about 1-3 times every time it is driven). The problem is worse when it rains a lot outside. I am afraid to drive the vehicle with my children inside because I have lost power on in the middle of a major interstate twice.

We purchased a 2007 tahoe in august 2012. Since this time, my wife and I have both experienced multiple electrical starting issues with the vehicle. A jump start or boost will often allow the vehicle to start. However, there have been situations where we have not been able to find an available boost. We have been stranded in parking lots, family vacations, work, and our kids games or practices. As noted in many of the complaints, the starting problems are intermittent and there are times a boost will not start the vehicle. In fact, we even began to lose power traveling at highway speeds during a family vacation this past summer. This is very disturbing issue for gm and their apparent inability or unwillingness to correct the problem. In addition to the starting / loss of power problems, a cracked dash and faulty cruise control is something that should not happen with the technology available. Based on a review of the complaints, it may likely be a battery cable issue. Gm must recall this known problem!!!

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.
