While driving the envoy at about 45 MPH, a warning light saying "reduced engine power" came on suddenly, the car dropped down to about 20 MPH, and that continues to occur. I can turn off and restart the car, but the problem returns within a minute after driving it again. I started investigating what that means online, and, as with anything else on the internet, I see many opinions, guesses, and possibilities. Could be a bad sensor, bad throttle control, bad wire connections, etc. But this much appears clear: (1) it is a gm problem, and a very, very common one. (2) it is a dangerous problem. This seems pretty obvious - the car suddenly loses speed and evidently sometimes stalls out altogether. But hearing about so many other people's scary experiences just confirms this. (3) it can be difficult and expensive to diagnose and fix. When I think of these facts, coupled with gm's recent history, I immediately think "recall." this certainly appears to be an appropriate situation for a manufacturer to step in and fix the issue before more people get angry with gm, get hurt, or get killed. I called the dealer who sold the car (I am the second owner), in columbus, ohio. I was told that I can bring it in for a diagnosis for $110. (gee, thanks - wouldn't have thought of that.) the customer rep looked up the VIN and said that the vehicle was not eligible for recall or any special policy. Therefore, I am contacting you in hope that something else can be done.

Headlight low beams suddenly turned off while driving down the road at night. The first time it happened, they turned back on after a few seconds. The next year it happened, they stayed off until pulling over, turning off the car and restarting it. This problem has been reported by others on the internet, and seems to be restricted to the chevy trailblazer and gmc envoy. The reported fix is to replace the low beam relay.

Stop engine/low oil pressure display continually comes on and while driving, the vehicle hesitates and at times will stall. After replacing PCM, oil sending unit, throttle body assembly, cleaning the pcv valve and map sensor and multiple other parts, I was told that the dealership did not know what it was and stated that they could replace the cam shaft actuator (for a cost of approx. $885), but they could not guarantee that would resolve the problem. I have taken my vehicle back to the same dealership from 02/14/2011 until 11/07/12 and still unable to fix the problem. I've filed a complaint with gmc manufacturer, but still have not been able to resolve my issues.

Everything started april last year and its one thing after another since. First my engine started stalling, while driving. One incident, I lost half a tank of gas within a 15 minute ride, which I have a 17 gallon tank. Then while driving on an expressway, it suddenly dropped from 70 to 20 before I could get over two lanes to get out of the way of traffic. Ive cleaned the throttle body, ive cleaned the camshaft actuator, ive replaced the air filter, fuel filter, and the oil twice within a 8 month period, and yet it still continues to stall. Now I recently change the water pump to see if that would help, even though my car was not over heating, now its stalling even worse; I cant even make it through a drive through without having to start it twice. Second and even scarrier issue, I hit pot hole one day and before I could make 15 miles, I heard grinding. A cv joint had to be replaced, then two days after that the other cv joint broke off and broke my front axle disconnect assembly. Did I hit anybody? No thank god I was in the right hand lane and could get over without hitting anyone or causing injury to myself. Ive replaced both cv joints and the assembly now and even did the struts while I was at it, but have also been told I need control arms now. And still my car is stalling, grinding when I turn and I cant get the check engine light to clear long enough to get it inspected. My drivers side windshield works when it wants to and now the car is starting to vibrate unbelievably. Ive kept my oil changed, ive kept my filters changed, ive never taken this thing off road and have had it over 7 years and just in the last year I have dumped more money in this car than I have since ive owned it.
