2003 Mercedes-Benz C230 Owner Comments

problem #8

  • 9,000 miles


1. exiting a curve on a windy road at approx. 30mph, driver applied throttle causing an automatic downshift into a 516ftlb torque lunge. With no steering control in 1-second we were in the opposite lane. Driver fought to regain control during second no. 2. then a limo blew through a stop sign on a merge landing right in front of us. Both driver's braced on their gas pedals. 2. the Mercedes cl & sl classes have the same front seats with an integrated seat belt system. Since it was only connected to the seat, the seat failed without even a bruise to my right shoulder (by over 30-40 degrees). I was left against the dash board (with my seatbelt on) throwing limbs at my survival. To add insult to injury, after breaking my left femur twice, smashing two knees, breaking my forearm, hitting my head atop my left hand on the dash and leaving my body when I pushed back and returned I had enough time to think the air bag has yet to go off. Then it did, picking me up by my head, smashing it against the moonroof before finally coming to rest in a mangled seat position. 3. in the 2.75 years it took to get to writing this correspondence, Mercedes has increased their cl power options by another 150hp and 250ftlbs of torque to 650hp/750ftlbs of torque with the same seat/belt arrangement. Nhra rules require 5-point harnesses attached to frame/rollcage components for a car capable of traversing the 1/4mile in 12 seconds or less. The CL55-65's range from mid 12's to mid 11's. and fail to connect any portion of the belt to the vehicle's frame. It makes no sense especially in a car that weighs 4400lbs to leave their occupants fending for themselves in mid flight while "buckled up".

Transmission failure. Rusted and corroded trans at 24,000 miles caused by faulty Mercedes valeo radiator. Mercedes own star bulletin tells dealers about this issue but my dealer decided not to check it out and now Mercedes and dealer are refusing to help when this is a known problem on many of their models and should be a recall.

I am the owner of a C-230 4 door sedan VIN#[xxx]. 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. 2nd, am I paying a fair lease rate if the VIN# is for another body style. This car has been nothing but nightmare to deal with since the day I purchased it. It has been serviced 8 times, transmission work, 2 computers, camshaft, new radio, idle issues, brake system failed, and so on. It's a complete lemon. It is going in next week again. I have only 21,000 on the car, and drive my 2nd car more a 79 300sd Mercedes as it is more reliable then this new car. I need somewhere, someone to go to, any information would be greatly appreciated. Thanks so much, [xxx] - phone or email updated 07/18/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

A year ago, I brought a C230 compressor at Mercedes-Benz and since then, I had to repair my A/C twice, the ABS light has been fixed twice in one week, and now my transmission is acting out. Although I have brought my car in a great deal, the problem(s) still exist. In one month alone, I brought my car in about 3 times to fix almost the same problem(s). My last visit was this past week, and just today, I got my car back and the transmission still feels funny. It jerks when I step on the accelerator and for some reason, I feel more unsafe now then before.

Vehile is an automatic. Vehicle "jerks" hard when lightly applying gas. This can be compared to starting in first gear (manual transmission) when not fully depressing the correct combination of gas and clutch. This happens when traveling from a dead stop at a traffic light or pulling into a parking space. Have had several near misses in hitting other vehicles.

I bought my Mercedes C230 kompressor 9 days ago. It has only 380 miles on it. 2 days in a row when the car is placed into drive the entire vehicle shakes violently. Mercedes is going to attempt to fix the problem. Ss.
