2002 GMC Envoy: grinding or squealing brakes

Filed May 6, 2013 · Engine, Fuel system · 165,000 miles · TX

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.

Spare tire hoist secondary latch frozen, 2002 gmc envoy. Spare tire could not be removed from hoist when a road hazard blowout occurred. Tow truck operator could not remove spare. After a tow to tire vendor, they could not get the spare down. Upon visiting a dealership they could not remove the spare tire and said the mechanism was 'frozen' and had to be replaced for $250, but they didn't have the part in stock. After a trip to another dealership, they cut the hoist cable, removed the spare and replaced the hoist part. One can only imagine the trauma if the family had been on us highway 50 in the middle of nowhere when this incident occurred. This must be a prima-facie violation of the fmvss code that requires a spare tire. Yes, the spare tire is present, but it can't be installed on the vehicle. One would hope that automotive engineers know that the underside of a vehicle is subject to corrosion and design accordingly. Researching this issue, many enthusiast forums and other blogs reflect the frustrations of owners with the same situation. The common grassroots solution is to cut/grind off the secondary latch. Thus defeating the safety system intent. One can only hope they are not behind a moving vehicle with such a modification when the spare tire drops. Gmc customer service, while polite, informed that they could not reimburse the cost of the hoist replacement because there was not a service bulletin covering the problem. Yes, the vehicle is long out of warranty, but this is a serious customer safety issue. From the forums and blogs, it is obvious that this is a pervasive problem, and the 'fix' might be more dangerous than the initial issue.

When having my 02' envoy serviced and state inspection by my gmc dealer the service manager called and told me, I would need to r/r my front rotors. The pads were half worn but the rotors smooth surface did not exist. It looked like they were not machined thoroughly. Ser. Mgr thought I lived near the shore, stating salt water would usually causes this. I do not live near the shore and do not go the beach. I drive this vehicle to and from work all highway driving. My vehicle has 41225 mi and has always been serviced by gm. I have owned gm vehicles for 38 yrs and the cars with rotors never looked like this. This looks like a manufacturing imperfection. From reviewing the odi list for this vehicle, others have also documented similar complaints. If I did not bring the vehicle in for the state inspection I would never have know this defect existed. This gave me neither warning in braking, stability nor squealing/ticking from early warning system. I should had asked for old rotors or taken a picture. Front rotors and pads replaced at my expense.
