I also owned a 2003 300M Special which I consider one of the most beautiful cars ever made. The only problem I ever had with it was exactly the one you described. I was driving on a long trip across Texas when the CHECK ENGINE light came on and the car began to sputter and miss. I pulled over immediately and put it in PARK, and attempted to rev the engine to see if it was still sputtering. It was, so I shut it down and popped open the hood. It was not overheating, all belts were in place, no leaks or anything else obvious. After about 5 minutes, I restarted the engine and it cranked right up like new. No more sputtering, but the CHECK ENGINE light was still on. I turned it off, waited a minute and restarted it and the light cleared. I completed my trip with no further trouble. About a week later, it happened again, this time within a mile from the dealership. I pulled in without turning the engine off and pointed out the CHECK ENGINE light so they could check it. The technician determined that something called a "crank sensor" was failing and need to be replaced. Apparently, it counts the revolutions of the crankshaft and sends that information to several computers that control everything from the fuel injectors, timing, transmission shift points to emissions. I had to pay just under $250.00 for the crank sensor replacement. Since then, I never had another problem with the car. The car has over 60,000 miles on it and still runs like new.

Starting Problem -Cigarette Lighter Plugins?
This is an odd one. I have a 99 300M and wife has the 99 CONcorde. Recently -last three mos. she has had start problems a dozen times. The car will start then immed. die. Then turning the key has no response at all. Wait several minutes and does same. Unplug her IPOD or GPS from the cigarette lighter plug and it starts right up and runs fine. I didn't believe it and then saw it happen twice this weekend. Her cigarette plug is in the on always position. Any ideas? Thanks Roger /Nashville

We have 99 Concorde and 99 300M. Both show avr fuel use at 20 city and 29-30 on interstate by the overhead display. Sounds too good. Do you believe that or not? Roger /nashville

I have recent posts on different 300M forums and while that is a little high it's not totally unbelievable. My 2004 averages 18 mpg around town year round.
70+ mph average conditions (no headwind or AC) gets 26mpg and on a trip a month ago on slower backrounds at 55 mph I was getting 28-29mpg. I consider those excellent for a comfortable 5 seater sedan with OOMPH. But if you drive it hard those will drop, and it's hard not to stomp the gas on this beauty occasionally.

Sounds about right, actually. I don't have a Special, though, and I still run 89 octane religiously.

I do agree with you on its one of the most beautiful cars ever made. Thanks so much for your reply. I've been reading a lot of the messages and its amazing all the different responses. But your solution seems to be the majority. So I guess my week old car will go to the shop and get that done. Thanks again.....

Hey all. Good to see that 300Ms are still running strong. My 99 Candy Apple Red is long gone, lease ended in 2002. I then leased a 2002 Acura TL-S which was returned in 2006. I have been driving a 2005 Pontiac GTO since then. GTO gives me lots of joy, but I sure still miss the 300M.

My first 300M was a 1999. It was fully loaded, Inferno Red Crystal Pearl Coat with a tan leather interior. It was one of the most beautiful cars I have ever seen, but it was a real pleasure to drive as well. I traded it for my second 300M, a 2003 Special in Midnight Metallic Blue, with a two tone gray and black leather interior. The upgrades of the Special made a great car even better, (dual exhaust, ground effects body work, better handling and performance, better brakes, and even a better look with the rear deck spoiler. It also came with HID head lights, vast improvement over the halogens. The 18 inch wheels and tires made it better on the road. Alas, all was well until I bought my wife a 300C Heritage Edition in Inferno Red, loaded with every option available including the 5.7L HEMI and the Mercedes 5-speed automatic transmission. The contrast between the two cars is astounding. Chrysler should not have discontinued the 300M, and they should have called the 300C an Imperial. I considered the 300M a perfect car, but the 300C is simply incredible. It is truly a Mercedes in Chrysler clothing. I suppose if you really wanted to spend 80K on the Mercedes, you could, but it would be more practical to spend about 70K on TWO 300C's loaded with features even the Merccedes lacks. That is what I did.... I love them!
