My truck has a tendency to stall when at idle speed. Happens on an intermittent basis. I first took it to allen samuel's Dodge on 610 freeway in houston, tx. They could not reproduce the problem, suggested throttle body service which was perform. Didn't correct the issue. Took it to gilman Chrysler on 59 sw freeway in houston, they couldn't reproduce the problem. Within the past two years have had fuel injector service, spark plug replacement and fuel pump replacement in an attempt to correct this issue, all at the above dealerships. Vehicle now has about 75,000 miles. Problem still exist on an intermittent basis. I am afraid that it May stall in traffic while at traffic light or freeway traffic jam which could lead to injury or death. It is my understanding that the 2007 Dodge nitros were recall for the same problem. …
I just bought this vehicle. Every time I fill the gas tank, the gas pump will click off when full and as soon as it shuts off, about a half gallon of gas will burp out of my gas tank and cover the side of my Nitro and the ground. I've read a lot of reviews of a lot of other people having the same issue. They have taken it to the dealer and there is a defect in the fuel tank and the tank needs to be replaced. This is a major safety hazard!!! What if I were in a roll over accident? The fuel would poor out and one little spark, I'd be blown to shreds!!! Or someone could hit me in the tank area and once again, an explosion!!! Since buying the vehicle, I have read complaints from so many other people with the same issue. Please recall these Dodge nitros for the owners safety and the safety of everyone around us!!! Please!!! …
When filling the gas tank up as the pump kicks off at least half a gallon of gas spills out of the tank splashing onto my legs and spilling on to the ground. I bought this vehicle used and was told to contact a Dodge dealer about a possible recall but the dealership has told me there isn't a recall but they've had several complaints about this issue. Also, recently I have been unable to lock my vehicle because a few seconds after activating the locks either manually or using the key fob the car unlocks and the headlights come on. I had to take the battery out of my key fob as it would continuously unlock and activate the headlights during the day and night. When manually locking the vehicle it still unlocks itself a few seconds later but does not continually unlock like when the key fob is in use.
I just bought my 2008 Dodge Nitro. Every time I fill it with gas and top the tank off, the pump clicks off and a second later, about a half gallon of gas spews out of the vehicles gas tank, down the side of my vehicle and onto the ground. This is a major safety hazard not only for Nitro owners but for the public around us as it could possibly lead to an explosion in the event of an accident. I've read many complaints online from other Nitro owners with the same issue. A few have taken their vehicle into the shop and was told that there's a factory defect inside the tank which is causing the issue. They replaced the tank and the problem was fixed. Please... We need to get these vehicles recalled and fixed as soon as possible!!!
3 different times I have had to replace the battery in my Nitro due to the stereo. The radio is not powering down properly and keeping the communication bus awake causing parasitic battery draw. I have a mygig head unit with navigation and sirius satellite dvd player. At time the the Nitro will lock me in or out due to the stereo not powering off properly due to this issue you also can not get satellite service to work. Dodge needs to recall this issue as we did not ask for the issue. Also when filling up with fuel it does not stop on it is own like other cars and trucks, it spits fuel back out at you and spills everywhere on you the car and ground. The battery problem happens when it is turned off with no key in the ignition.
