Tl contact owns a 2001 GMC Jimmy. The contact noticed that the on-board diagnostic system warning indicator would consistently illuminate on the instrument panel. The vehicle frequently misfired, which caused it to be inoperable. The dealer stated that he needed to replace the scpi fuel injector and the mass air flow sensors at the cost of $1,150. He is in the process of having the vehicle repaired. He called the manufacturer in reference to a voluntary recall for the state of california for 1996 to 2001 SUV's, but was not provided any assistance because the recall was not applicable for his state. The current and failure mileages were 72,000.
My fuel gauge in my 2000 Jimmy began fluctuating wildly in januray 2008. When the tank was filled it registered fine but after some gas was consumed the gauge proved grossly inaccurate. I had to watch my trip odometer to gauge the amount gas left in the tank. I went to several mechanic's and was told that it was the sensor. However, from what I was told, the sensor and gas pump are both connected and submerged in gas. I had it repaired and luckily it was only the sensor. It cost more than $400. I was told that if the unit was severely corroded, I would have to replace both the pump and sensor. This is not a comforting experience. I assume there is no danger from fire, but I would expect the gas gauge to work and it didn't. I find it interesting that another person experience the exact same problem, only earlier.
Tl contact owns a 2000 GMC Jimmy. The contact stated that the spider port injector was leaking gasoline between the firewall and the engine. There was a recall for the previous year, make, and model vehicle, but not for the 2000 Jimmy. The contact smelled gasoline in the vehicle and took it to a personal mechanic.

The vehicle was then taken to an independent mechanic, who replaced the fuel pump three additional times due to the recurring failure. The electric fuel pump was replaced a total of four times but the failure would still recur sporadically. The vehicle would also exhibit a loss of power sporadically after the numerous repairs to the fuel pump. The manufacturer was notified of the failure. The approximate failure mileage was 34000.

Over head dash light won't work. Took my SUV to the dealership on a Friday 11/09/01. All problems were occuring at that time and they could see for themselves. I was informed the the diagnosistic test showed 5 trans codes. And that wire to the transmission was loose and they reconnected that wire and all codes were now clear. The very next day my SUV began doing the same thing all over again. I called the dealership and reported the problem on Monday 11/12/01. I was then told that the problem May be caused be a wire leading from my ignition to transmission. And that I might need an ignition switch. And that to do the work it would cost me $400 to $500. …
Dt: on 5/24/05 caller was driving at 40 MPH on level ground on the highway and the spare tire fell out from underneath the vehicle. The cable that holds the spare onto the vehicle broke and allowed spare to break away and fell onto the highway. The windshield wipers have caused many problems in the past as well. The wipers would start and stop unannounced and had to be repaired and the blinkers would come on and go off on their own. The consumer believed there was a general problem with the electrical system. The car was regularly maintained. Each time the consumer filled the vehicle with gas, the inside of the vehicle would smell like gas and for a couple of days, the gas gauge did not work.
