I took my 2007 Chrysler in because of fuel gauge not reading properly, dealer said I had bad fuel pumps, changed pumps and seals approximately $1100 gauge still not working dealer claims bad module paid $350. 00 gauge still not working, dealer said it could be battery cable changed that still not working, dealer said it have a bad fuel tank, changed tank fuel gauge still erratic, now car cuts off for no reason, you cannot put gas in the car without the car acting as if it is full, fuel gauge still does not work and car displaying more issues now than I started with and I have had the motor mounts at least 5 times since I had the car. Dealer even said fuel gauges sometimes jump around. I feel like I have been taken total advantage of, it appears I have been sold a defective car and no one wants to take responsibility for it. Look at the hundreds of similar complaints and Chrysler does nothing.
A check engine light illuminated and the dtc code indicated a fault in fuel evap system. A smoke test on the system revealed that the plastic tube on the fuel pump had snapped off requiring a fuel pump replacement. The fuel pumps are connected by a hose which sits on top of the fuel tank. The connection point at the on the primary fuel pump snapped off. The fuel pump, and tank is mounted above the exhuast system, so it's probably not an ideal situation to have deffective parts leaking small amounts of gasoline on top off hot exhaust. Also,after completing repairs my gas milage improved by 10%. I have saved the deffective part incase its needs for failure analysis.
My car won't start at least 4 times a week. You will be driving and it almost stalls. The gas tank fluctuated and does not read the right amount. Also when in reverse it has taken off on it's own at a very high rate of speed. I have had it into the dealership 25 day and 15 times in 9 months and they have replaced the map sensor, the pcm & bcm, the fuel injectors, several sensors and filters all to no avail and this was all just for the not starting. We sent in the lemon law paperwork and Chrysler refused to call us back via the dealership and refuses to talk to us when we call the 800 number. Looking at other forums there are several people with this same problem and Chrysler also ignores their complaints.
