Problems with 2003 GMC Envoy XL SUSPENSION

We purchased our 2003 gmc envoy xl sle 8 cylinder brand new at alden buick in fairhaven, mass in july 2003; for the past 3 years we had it serviced at robertsson's gmc 2680 cranberry highway, wareham, mass.02571,508-291-0044. we had it reconditioned at this dealership last year, spending $4000.00; we had it inspected at this dealership with the massachusetts vehicle check; it passed the front end check and frame check on 8/4/17. i was driving the vehicle in late december, and hit several deep potholes caused by an ice storm; shortly thereafter i lost steering control of the vehicle. i had it towed to alden buick/gmc in fairhaven, mass. to be told that the entire frame had collapsed due to extensive corrosion and rust. i had it towed to robertson's gmc in wareham and filed a claim with commerce ins. co. to hopefully cover the damage to the frame; commerce denied the claim stating"the frame assembly was severely rotted and this extensive rot allowed the right front control arm to break awayfrom the mounting point on the frame rail. gmc issued a technical service bulletin stating that some envoy models suffered from extensive frame corrosion. why did robertson's gmc pass the vehicle on the safety check, and why was i not informed of the vehicle's frame corrosion before i spent the $4000.00 reconditioning it? why is frame check and front end check listed as pass on my vehicle when this corrosion and rust was present at time of insspection? fortunately neither i nor any of my family members were injured while driving/riding in this vehicle.

Tl* the contact owns a 2003 gmc envoy xl. the contact stated that while parked and starting the vehicle, the rear end abnormally rose higher from the ground. in addition, the contact stated that when driving, the rear lowered near to the ground. the contact also mentioned that at times one side of the vehicle was higher than the other side. the vehicle was taken to an independent mechanic but was not diagnosed or repaired. the manufacturer was not made aware of the failure. the failure mileage was 140,000. the vin was not available.

Driving on highway when rear of vehicle felt like it was riding low. got off highway at next exit to check back of truck. rear of truck was sitting low. turned truck off waited a few minutes, turned truck back on. the rear of the truck did not rise. this can not be safe for the rear suspension system to disengage while driving. i had previously noticed when the truck is first turned on that the rear suspension would engage and the rear of the vehicle would rise. *tr

The rear of my 2003 gmc envoy xl goes down after the vehicle is turned off. usually the rear of the vehicle goes back up after the vehicle has been on for a couple of minutes. once, though, the rear suspension failed while driving. now my the rear on my vehicle is dawn this is a second time and no goes up that look danger for drive. *tr

My 03 envoy xl air compressor will not inflate the air suspension. the rear end is sitting way down with a little bit of air in the shocks but will bottom out easily. the compressor comes on for about 30 sec to 1 min at startup but no increase in ride height. this is the second time this has happened - 1st time was about 3-4 months after i bought the car in 2006 and the dealership fixed it for free. i have been reading on-line and have seen similar complaints over the years for the model - 2003 gmc envoy xl. *tr

For the last 6 months, the rear of our 2003 gmc envoy xl goes down after the vehicle is turned off. we have had the compressor for the suspension replaced but it continues to happen. usually the rear of the vehicle goes back up after the vehicle has been on for a couple of minutes. once, though, the rear suspension failed while driving. *tr

Tl*the contact owns a 2003 gmc envoy. after the contact placed fuel in his vehicle, he continued to smell an odor of gasoline. he crawled underneath the vehicle and noticed fuel leaking on the outside of the gas tank. the gas tank weld was rusted and cracked, causing fuel to leak out of the tank. the contact also stated that the front suspension of the vehicle was banging whenever he drove over the smallest bump. in addition, the fan clutch was making a clicking sound. the dealer informed him that the vehicle was out of warranty and the repairs were his responsibility. the current and failure mileages were 88,000.
