problem #7

Recall has been issued on faulty gas tank. Had car inspected by Isuzu facility 2/4/16 and new part(s) ordered. Cannot get any information as to when part will be in and my car repaired. In the meantime, driving with faulty, gas-leaking, probably dangerous car. GM apparently not communicating with Isuzu and parts not getting produced.

My transmission has had to be fix 3 times 2 of those time me and my 5 children where driving on the freeway and my car stopped picking up speed and we had to pull to the side of the rode. My back vents for my A/C do not work, the back door opens all the time one time it opened and all our groceries fell out and when I try to pump gas into my car it would take forever the pump would stop like it was full but now it just spills out and my car smells like gas so bad on the inside I can't even drive it anymore. It's one thing after another and I have only had this car for 2 years and it's one thing after another.

My car has smelled of gas and I have been told there is a fracture in my fuel tank inlet check valve. This has been a problem with the 7 passenger Ascender but they are doing nothing with the 5 passenger Ascender though it is the exact same part that is faulty. I have contacted Isuzu and am taking into their service center but I want this complaint on record in case something should happen such as my car exploding. The fumes inside the car are so noxious they are making me sick and I have to drive with the windows down.

Had check engine light come on and had checked out. Code brought up said gas cap problem. Replaced gas cap and went away for a week. Had problem come back and asked mechanic and said it was a common problem on these vehicles. Mechanic also said it could be connection to fuel tank from gas fill tube. Had checked out and was ok. Put on new gas cap again and went away for another week and came back. Done with it. Tired of putting money into a problem that won't go away.

Ascender 6-cyl

  • 145,000 miles
There has been ungoing electrical issues since buying this vehicle new. The headlights have stopped working and there is an intermittent problem with the lights and the internal chime. Sometimes the lights don't come on or the chimes can not be heard and then it is working properly again. The engine in the vehicle ihad to be orepalced just before it went to 60000 miles so, it has an 2005 engine. This engine has a hard revv when shifting gears. There are gas fumes coming into the cabin. The vehicle has been taken to the mechanic several times and they have not been able to find the leak. I don't live in the salt belt area. I live in northern fl and this is not the only place that the vehicle has been, but it has not been where there are salted roads like the nort East and midatlantic. Request your assistance.

Ascender 6-cyl Diesel

  • 124,000 miles
Continuous gas smell in and around automobile when starting the engine. Engine light came on in Jan 2013 although the smell has been present for many years. Took auto to repair shop and discovered that their was a sizeable crack at the opening of the gas tank. Around 1,500 dollars later a new gas tank, new fuel pump assembly, I find it hard to believe there is no recall on this part from GM, especially since searching the internet and discovering how many have reported this same exact issue and the scary thought that the car could have blown up and any time. A class action suit needs to be filed against GM.
