The vehicle throws the abs, esp,break and traction control lights and then while driving completely at random then turns off WHILE DRIVING!!!! which can cause an accident (I and my daughter are lucky to be alive) this is not ok the vehicle drives fine then at random throws those lights and shuts off after restarting it the check engine light comes on and says the transmission shift solenoid b is malfunction and the vehicle wouldn't shift properly. Luckily I had my code reader I. The car with me I cleared the code and now the car drives fine until this happens again I'm scared to drive it this is dangerous their's no warning. I drive on the highway everyday their's no warning it happens at random 2 times I've been lucky. …
An intermittent electrical failure is affecting multiple vehicle systems. The vehicle has unexpectedly stalled while driving on the interstate, leaving it without power in moving traffic. It has also experienced repeated no-start conditions, transmission entering limp mode, the engine continuing to run after the key was removed, and random operation of the horn, windshield wipers, washer pumps, and other electrical components while driving and while parked. These failures occur without warning and create a serious risk of a crash, injury, or death due to sudden loss of propulsion in interstate traffic and unpredictable vehicle behavior. The problem has become progressively more frequent despite previous repairs. The vehicle is available for inspection. I fear for my life.
The TIPM in these vehicles are faulty and nothing is being done about it by Dodge. There are hundreds of complains across several forums and every time Dodge is contacted about the issue they use the no recall excuse. I have a Nitro myself and it has multiple electrical issues for no reason other than poor manufacturing. The TIPM is the issue and it's not just my Nitro having this problem. My vehicle has accelerated without my assistance, it's had braking issues when there should be no issue. Components that need my action to work have activated on their own, such as... horn, wiper, wiper fluid, accelerator, etc... The wiring in these vehicles are faulty and it needs to be fixed by the manufacturer at their expense. It's time they step up a make it right by the consumer.
I had just entered Gene Snyder Expressway going west when my throttle light started flashing and I lost gas pressure and it started going down fast and then it shut off and right in the middle of rush-hour traffic and it's 65 mph on the expressway and People as usual go around 80 mph and I just entered and almost got slammed in the rear but luckily I got off the highway in time. I still have not been able to turn my truck over at all. It is in the throttle electrical system, which is currently being checked out as we speak but it's spit out two codes. One was PO633 and one was P2 112.
TIPM system and/or electrical system failure. Right turn signal intermittently works when it wants to. Door locks from the inside at random or will not lock at all when using the master lock button. Now car will not start or turn over at all. Zero sound comes from he vehicle while turning the key. Commonly known problem with other Dodge Nitros and nothing being done about it. A recall needs to happen or at the very least acknowledgement from Dodge.
...so, I left my house, got about a block down the street and all of a sudden my horn starts blaring, windshield wipers started moving, the windshield wiper fluid sprayed, all of my interior and warning lights starting blinking in and out and my Nitro started sputtering. At this point I had lost power steering and power brakes but I managed to pull it over to the curb and the car dies. I'm sitting there thinking to myself, "what in the hell?!" I was already startled from the horn randomly blaring, so I'm in the middle of swallowing my heart when heavy, thick smoke starts coming from under the hood. ...and it stinks like smoldering wiring. I snatched my keys, popped the hood (which probably wasn't too bright in hindsight) and ripped the wiring off of the battery terminals. It was hot under that hood and I'm glad I had the wherewithal to disconnect the battery. …
Started vehicle and drove a block with heater and wipers running. The heater shut off and on and the horn started blaring off and on. During this time the locks were going up and down too. Pulled over, turned ignition to the off position and removed the key. The engine still ran for a little bit, horn still blaring, and front/back wipers still ran without a key in the ignition. Eventually the engine shut down with everything except for the wipers. The wipers continued to run until we had the vehicle towed away a couple hours later. There was smoke coming from the fuse box and a terrible smell of a melting electrical system. This is a huge safety concern because I could have been on the highway traveling over 75 miles per hour in the rocky mountains when this all occurred. Thankfully this happened while exiting a business instead. Recall needs to happen before someone dies. …
