What 2003 Mercedes-Benz C230 owners say
Engine & cooling all 22 →
The 2003 mercerdes Benz 300c engine suddenly caught on fire while driving it to work. The car stalled, flames shoot out the front hood, the car would not restart, so I coasted to the firm. I opened the hood to see blue flames shoopt 20 feet in the air. A passerby tried to put out the firwe unsucessfully with a fire extiquisher. The flames got hotter and shot 60 feet in the air, and police and fire department responded and were finally able to put out the fire . The engine block melted down ,and there was a large hole burnt into the pasenger space. The car was totaled. I wrote Mercedes Benz, and they were being nonresponsive. I have photos of the melted engine block and the large hole burned into the pasenger space through the engine firewall.
I was driving the vehicle home from work and heading uphill. My automatic air conditioning clicked off, and then I noticed a strong chemical smell. Smoke came out from under my hood. There was no safe place to pull over, so I drove another 1/4 mile until I crested the hill and came to a dip. I noticed flames coming toward me from between the driver door and the dash. I immediately pulled my car over and put it in park, grabbed my stuff and got out. The car completely burned up. I get my car regularly maintenanced by the dealer, and it said I had 1800 or 1900 miles until my next service.
Transmission & drivetrain
At 178,000 miles the timing chain tensioner failed while the car driving approximately 25 MPH and allowed the timing chain to skip several teeth leaving the car stranded and potentially causing thousands of dollars worth of damage to the engine internals. The car was dealer serviced since new and always had maintenance on time. There is thousands of people online that have had the exact same issue and Mercedes Benz USA refuses to do anything about it yet they acknowledge they made them wrong because they have updated the chains and tensioners.
I am the owner of a c-230 4 door sedan VIN#[redacted]. I have an issue that I was looking into addressing when another major issue just arose that I need help from the manufacturer who I have contacted but not received a response. 1) last week I decided to quote insurance and make a change to allstate. Once they put in the VIN# major issues came. The price was way different then what I was paying with Mercury. To make this short, after talking to my broker at Mercury, it turns out my 4 door has the VIN# of a 2 door coupe. I called beverly hills ltd where I purchased the car new. They did nothing. I have the original temp registration from the day I purchased the car new, and the dealer typed coupe not four door and on the lease agreement. I did not notice this. Here are my issues. The coupe is more expensive on insurance - I have been overpaying since 2/2003. …
