We had a brake booster vacuum line that connects to the aluminum intake with a plastic fitting on a 2002 mercedes clk320 (173k miles) that got brittle and broke. Thankfully no one was injured or killed. I'm an ex-mechanic and have never seen plastic fitting used for the vacuum line to the brake booster on the engine. Over time this will get brittle and break. This vacuum line does 2 things, #1 it keeps the car running with normal power, #2 allows you to have brakes that operate normally. I have done a quick search and it's not just mercedes, other manufacturers do this in some and/ or all models of their cars. This was a wake up call for me especially being a mechanic. If I saw this as a mechanic it would have been reported. This is a major catastrophe waiting to happen. People are keeping cars longer and if this plastic gets brittle and breaks while out on the highway the person could lose engine power and/ or braking power. This needs to be brought to light and I want to do this not just for me but the other millions of people that could have this happen to them.

What 2002 Mercedes Benz CLK320 owners say
Most recent owner complaints, unedited.
There is too much rust on the vehicle! Car has never been in any accidents & has been washed & waxed regularly. Supposedly this is a very common issue with these cars which is disappointing. This poses a safety issue as if the vehicle is involved in a collision, the structural integrity is highly diminished due to the corrosion. What is even more scary is that the corrosion starts from the inside out so you will not be able to see the damage until it is too late. Mb USA: please assist/help & back your products up!
While on my way to work I stop to get gas. I get in my car to leave and key will not turn left or right. Also steering wheel was locked. I was stranded and had car towed the mb dealership. They said first I have to buy new key before they do anything which cost me $380. Got new key and that wasn't the problem. Then they said my eis needs to be replaced. They replaced the eis, then I get a call saying car still will not start. Now they say I need a esl(electronic steering lock) now my total jumped up to 2,200. I am so disappointed that all these problems can go out at the exact same time with no warning at all. There has to be something done about this common problem in mercedes.
Cluster recall for mb clk 430 2002 w208 comments: rep., I own a 2002 mercedes benz clk 320 the VIN# is:________. My concern is over its faulty display readouts that I hear many other owners are experiencing. The safety concern is that the left half of the display blank and it is impossible to read. It's hazardous as I have to squint to read the display which takes my eyes off the road longer that they should be. As part of this cluster, the temperature pixels and the gear selection pixels, which leads me at times to incorrectly down shift not knowing if I am in 1st, 2nd, 3rd or 4th gear, are hardly functional which has been mainly unreadable for some time now. I went to the mb dealer and requested to fix this issue and found out that the only way is to change the part, but this part is close to u$1,200 including labor. This is a safety issue and needs to be taken care of. As I stated before I am not the only one complaining about it, so I think you should consider a recall on this. Thank you for your attention. From the federal safety agency web site.
I was driving up the mountain home ,the gas pedal gave out. I set the cruise control on and drove an hour home. When I got home I looked under the hood and came to see that the throttle cable had came detached. The car only has 59,000 miles on it. This is the first time it has happened to me. I called mercedes-benz customer care number to see if there is a safety recall on this ,they said"no" but they could arrange a tow back to las vegas at my expense and they can check it out to see if they would be able to do anything for me. I would think they would tow and fix it without any expense to me for this sounds like a huge safety issue, I did come very close to an accident the car behind me almost rear ended me and I could not get over to the right due to other vehicles to the right of me. I hope someone could bring this to the attention to the right people.

I purchased a certified pre-owned 2002 mercedes benz clk320. Within the first month of purchase I began to have problems with the amplifier which was later discovered after being replaced 3 times getting wet whenever the car became wet. Resulting in a crackling and popping sound ultimately leading to complete failure of the audio system. After complaining to the dealer where I purchased the vehicle, I was refered to a mercedes benz repair shop. They claimed to not be able to find the problem after wetting the car which was a lie upon washing the vehicle shortly after recieving the back from the repair shop. Ultimately the audio system had castrophic failure which resulted in a very load sqealing sound which blew out the amplifier the left door speaker and my ear which has resulted in permanent ringing in my ears, and hearing loss which has cost me to date nearly $4000.00 dollars in medical bills and has permanently altered my life affecting my ability to sleep, finished school and deppression. This was my celebration car for working hard to get into my current field as a computer specialist for the dod. I now have to take sleeping aids to get to sleep. And god forbid if I wake up during the night because going back to sleep is nearly impossible. I had no idea this was an issue with mercedes benz vehicles but further investigation on the internet has LED me to a couple of websites of audio repair shops in florida and california which show this is a national problem. Mercedes benz ultimately discovered it was defective drain plugs directly over the amplifier which allowed water to leak directly onto the amplifier when the car gets wet including with morning dew which the water drains directly onto the amplifier. The amplifier blew up while driving to work and fortunenately for me no other person was injured as I had to pull over because I thought the car was going to explode; the sound was that load. The car had a little over 19,000 miles when this occured
