2006 Chrysler 300C: sudden loss of power

Filed Nov 3, 2022 · NY

The car is prone to intermittent stalling, in which the engine cuts out without warning or signs of stumbling. Often it happens at idle or when initially accelerating from idle, but has also happened several times at speed, up to 40 mph, with accompanying loss of power steering. Sometimes the engine kicks back on after a momentary loss of RPMs, if at speed, but other times it does not. I have brought it to two Chrysler dealerships and three independent mechanics in an effort to find the problem, with various parts being replaced, including the X53 extended warranty for the 19 gallon fuel tank, but the problem persists without successful diagnosis. Only one of the independent mechanics was reportedly able to replicate the condition. Usually, the check engine light, electronic throttle control light, oil light, traction control, and electronic stability lights turn on during a stall, and sometimes the check engine light stays on. The car may several trips without a stall and then stall multiple times in one trip. It usually does not generate a code, but sometimes produces P0700 and U0100 codes. The car always starts again following a complete stall. These symptoms appear fairly widespread in 2006 Chrysler 300 vehicles, based on car owner forums. The level of fuel in the tank does not appear related.

Car is losing power and won't turn over when trying to start. After a few hours it will start and run fine until you turn it off again. New starter, new battery, new aternator wires fixed. Dealership doesn't know what's wrong with car

When driving the vehicle it will out of no where without warning shut off on you. Youy lose all power. I was on highway at 70 MPH and the vehicle shut off and with loss of power was hard to get the car to right edge of road and was almost hit by a semi truck. I have replaced on advice of chrysler the fuel tank, fuel pump, new PCM and new TCM and the vehicle still shuts off without warning. It throws two codes u0100 and p0700. U0100 is lost communications and p0700 is transmission fault. These are two generic codes and the p0700 is just a simple as the transmission going into limp mode when engine stalls. Chrysler dealers/service center don't know whats causing this, but you look all over the internet there is 1000's of the same complaint and nothing being done to help. I even called chrysler and they lied that they have never heard of this issue. It is effecting cars from 2005-2006 and is very dangerous. My girlfriend had her kids in my car and was using it and it stalled out and she was almost run into at 9pm at night because of the sudden loss of power and shutting off. I have written you numerous times with no reply back so I am assuming you guys are over looking this issue also. Here is just one web page with same problems as I explained: https://www.2carpros.com/questions/chrysler-300-2006-chrysler-300-car-shuts-off https://www.carcomplaints.com/chrysler/300/2006/engine/engine_stalls_shuts_off_while_driving.shtml and be advised most everyone has had their gas tank,roll over valve and fuel pumps replaced along with PCM and TCM and are cars are still shutting off causing a dangerous precedent for a deadly accident you nor chrysler seem to care about till one of us gets killed

Problem: momentary loss of power, check engine and etc lights flash. Sometimes stalls completely (when very slow or stopped). It has stopped on me a couple of times while turning. To stall while turning across traffic is unsafe. Parts replaced so far: gas tank (recall) gas pump accelerator pedal diagnosis: apparent intermittent connection at the PCM. Last repair attempt(11/29/17) the technician repaired the connection by aligning the pins (apparently some had pushed through the board) & cleaning the connection. It has worked fine for about 2 weeks since then, but is failing again. The technician now says there is a problem with the PCM (powertrain control module), possibly due to broken solder joints on the board that cannot be repaired. There are currently no pcms available from dealers and there are 67 units on backorder in the past few weeks . . . Many with similar failure modes. From the repair shop: "diagnosed and traced multiple faults to communication loss at power train control module. Removed unit from holder and while engine is running if the unit it tapped or shaken the engine will stumble or stall. - contacted computer repair shop and this is very common issue for several chrysler in last month or so . The main processor gets loose on circuit board but the contacts are so tiny repair is not possible. No local dealers have unit and there are 67 on back order in last weeks."

I was driving on freeway and all of a sudden the engine completely shut off losing all power. I was almost rear-ended as I drift to the side of the road. I turned key to off position and turned back on and it started. Then as I was driving again the engine started lurching and stuttering and the engine shut off then turned back on. This happened 4 more times. This morning on my way to work it did it again turned off on freeway almost causing an accident at 70 MPH. I see online there are many complaints of same issue. I called the chryselr dealer and they would not even listen to the issue but offered a $1800 fix, same fix that is recorded online that doesnt work

When refueling our vehicle, using the correct grade of gas, not topping off the tank and allowing the fuel pump nozzle to shut off automatically when filled, we are experiencing life threatening episodes of stalling out when entering traffic from a gas station, or idling in traffic, turning corners, and entering ramps to the highway it will stall and choke when we try to start it back up. We wait approximately 3-5 minutes before attempting a restart without engaging the gas pedal. But still nothing happens. When it shuts off we forcibly have to turn the steering wheel because you lose power to your brakes, steering, etc. And just pray that nobody gets injured. During the stall out there are no warning lights shown on the dashboard. Once we finally get it to hold a start, we must at high idle drive fast as possible, getting off the main road/highway/city street to immediately garage the car. Then we have to have it run with the garage door open for at least 2.0 hours. And then we cautiously drive it with me following my husband to make sure it doesn't stall out again. Once we get pass this stalling-out period the car behaves properly, and we have no further issues until we refuel again on a weekly basis. We only have this refueling issue when filling the car. It indeed is a problem that the chrysler group llc discussed in the letter we received may 8, 2014, in the 2nd paragraph "the affected vehicle population may experience a condition where the fuel shut-off float, in the multifunction control valve sticks, which may result in the vehicle stalling after refueling. This statement for us is definitely our problem. And we are planning to address it with the dealership asap. This has happened every week. The last time was october 30th 2015. We have now only filled it to the 3/4 mark and it has stopped stalling out temporarily.

Stalled on several occasions after filling the tank up. Also while going at lower speeds. Hesitation and lost of power afterwards. Since my last fill up, the car won't start now. I read that hundreds of other people are having the same problem due to a float swells up into a stuck open position, allowing an overfill condition.

The car chime will chime, the engine acts like it wants to stall, losing power for about 3 seconds, then it's fine. I received a sort of recall from chrysler about the problem, I called the dealership in raynham, ma., the first week of feb., 2015. I was told it would take about 2 weeks for the part. It has now been 9 weeks, and I'm told they are still waiting for 5 orders on this problem. I have had the car stall out, while driving in 35 MPH traffic, very dangerous! It doesn't appear to me that chrysler is taking the letter I received stating they came to agreement with the federal safety agency to seriously!!!

Vehicle stalls in the middle of the road for no apparent reason. Vehicle stalled initially while driving 45 MPH and I lost power steering and had to pull over to the side of the road to restart it. Dealer had vehicle for over 6 months and could not solve the stalling issue. Vehicle currently stalls while sitting at lights etc. Has not stalled lately while driving dealer finally released vehicle to me and basically said there was nothing more they could do as it was a manufacture issue.

This has happened at least 3 times in the last 2 years. I would fill up with fuel and after leaving the gas station the vehicle would stall causing me to lose power steering and brakes and having to stop in the middle of traffic. I received a alert from chrysler last year but have misplaced the letter. It stated that if I experienced this problem that I should take it to a dealer and they would replace the gas tank.
