My first incidence was driving and the steering would all of a sudden get stiff like it needed power steering fluid or something. Check it wasn't the fluid (this happened a few month ago I thought hmmm probably just something freaky) then 1/8/16 riding down the busy interstate highway the car acceleration just left. I pressed the accelerator to the floor but no speed. It was extremely scary. I had the car checked out...it's the classic problem I never heard of until today. ( intake manifold tumble flap) some plastic junk on an expensive car. If I wanted a junk car I would've went to the "junk yard" paid like 250. And be done with it. I'm very disappointed and angry. I'm glad my kids wasn't in the car and it wasn't a horrific outcome. Now I can't do anything with the car right now because it's expensive to repair for such a cheap piece that shouldn't have never been on it and because #1 I'm on a fixed income #2 I still have to pay for it. But what does mb care about that....its just a product to them, a money maker.

My check engine light is on. I had it looked at by my mechanic. He confirmed that it is the balance shaft. This needs to be replaced. I researched this problem and found many mercedes 230 models have this manufacturer's problem because the piece was cheaply made. This is a problem with your mercedes c230 2006 and 2007 models. In 2008 c230 model this was replaced with a quality balance shaft piece which eliminated the problem. I would like for mercedes corporation to pay for the full cost of my repair because it is a manufactured faulty piece used in the 2006 and 2007c230 models. Please let me know details to get this paid for. Thank you!!

Engine light comes on. There is a manufacturing issue with the intake manifold. The plastic actuating rods broke causing the internal flappers to stick out. This can suck into the engine and cause major damage to valves and engine head. Mercedes benz should not have used plastic rods that break. Mercedes should replace the intake manifold as no cost to the customer.

I bought the c230 at one year old. I had e perienced two times thatwhile freeway driving all power would be lost. Pulled over and put in park, rev engine a bit but RPM's would not move. Fast forward to december 2008 I sold car go my mom because I had a baby and car was too small. My mom since having car has lost power while freeway driving a total of six times now. Very dangerous as there is no "code" or "error" for mechanic when diagnosing, nor is benz ackowleding ghe issue.

My car engine light came on in june of 2014. I took it to an independent repair company. They explained at that time that I may be dealing with a balance shaft issue. As the months progress, my engine light would come on and go off intermittently. The engine light eventually would not go off. I took it back to the repair shop and they confirm that it was a balance shaft issue and that it was a manufacturers problem. I called and emailed mercedes benz for assistance since it was not negligent on my part that this issue occurred. After making several phones and e-mailing the ceo, they told me that I would have to get it checked by a mercedes benz dealer to confirm the issue. I made the appointment with the mercedes benz dealer in december 2014 and they confirmed that it was a balance shaft issue and that it would cost around $5,000 to repair. I called mercedes benz back to request assistance and they explained that since the car had no recalls and that it was not a new car, they would pay 10% of the repair cost. I explained that I did not have the money to pay for the repairs and that I should not have to pay for the repairs since it is a manufacturers problem. To date , I am without a car to drive because I do not have the money to pay for the repairs. Any assistance that you can give in this matter is greatly appreciated.

On june 9, 2011 I drove to sacramento, california to visit my cousin when I got there I went to lock my doors but the lock kept jumping up and down. It finally locked after 12 attempts. I took it to the dealer and they quoted me a price of $3500.00 to replace the regulator. The second incident occurred on july 18, 2011 with my brakes.the break warning light came on. I took it to the dealer and $795.00 they claimed I needed for both brakes and rotors which I could not understand since 6 months prior the rotors had been replaced. I again had to have the rotors and breaks replaced in july 2012 as well as the back breaks but this time I took it to another place other than the dealer and here it is 2014 and they are still holding and the cost was $495.00 for both front and back as well 4 new michelin tires the dealer wanted to charge me $495.00 for the back alone. The third incident occurred in las vegas I was in heavy traffic and the car shut off. It started back right away but I had a ten hour drive to make it home and this worried me. The fourth incident was with the sunroof I went to the car wash and the wax that was used caused the sunroof to stick after it dried and later the motor went out because of multiple attempts to open the roof, the dealer quoted me a price of $5000.00 to repair it. Last but not least the SRS light came on, I took it to the dealer and I was told that the drivers seatbelt and back seatbelt on drivers side were defective and if I had an accident the air bags might not deploy and the seatbelts might not hold, this will cost me $700.00 to have fixed. I don't have a money tree growing in my yard. Also my rear taillight kept going out and what we found was that the entire casing had caught on fire and burned. The entire unit had to be replaced. I have paid more in repairs on this cars than I paid in groceries over the pass five years.

Zero issues with this car until now. This week, june 2013, the car has 78,000 miles on it. I pulled up to a stoplight off the freeway, and the car started sputtering like never before. The check engine light came on - for the first time ever. The car stalled and engine died. It restarted, but when I pressed the gas there was no power, traffic was coming up the off ramp fast, I had to flash my brakes to get them to notice something was wrong but it was a close call. The car sputtered into the middle of a busy freeway overpass intersection with my family on board and eager traffic behind me. It was a very scary moment because the car went from completely reliable and trustworthy to complete loss of power and instability. I sputtered back home, creating the same dangerous conditions at every intersection. I took the car to a mercedes benz shop the next morning. After a lot of testing it was determined that the intake manifold needed to be pulled to look deeper into the engine. Hours later they found that the problem was caused by a defective plastic bushing of the intake manifold which broke and was sucked into cylinder #4 and #3. This caused the valves to bend and compromised the integrity of the cylinders and valves, according to the mercedes qualified technician. There is extensive damage to the valves, and they don't know what all they're going to find once they pull the headers off. The cost to repair the car is $4,400, but it may even be higher. The cylinders have to be sent to a machine shop to see if they have any other issues as a result. Who knows what they'll find. The mechanics stated that mercedes benz is aware of this problem, that those moving plastic parts in the intake manifold are known to crack and cause problems and should never have been made out of plastic, but I don't see recalls on this obvious engineering & manufacturing defect.

My check engine light came on so I went to mechanic to check. They performed a computer code test to find problem. The code indicates that the balance shaft is starting to fail. I researched on-line and discovered this is a known defect within this engine. Apparently mercedes is unwilling to assume responsibility for this defect. Repairing this problem is extremely costly and the buyer shouldn't bare responsibility for their faulty parts. I understand there is a class action lawsuit filed, but I can't find out the current status of it. This defect can cause immediate engine failure when driving causing the auto to stop in traffic. Being that thousands of mercedes vehicles have this defect I don't understand why the ntsb isn't stepping in.

I was driving home and noticed that when I would accelerate after coming to a stop the car was extremely slugglish. I would have to almost floor the gas pedal in order for the car to begin moving. I pulled over and then put the car in neuttral. The jerked violently and shifted very hard as I then tried to put it in reverse and the into park. I tried to put the car back into drive and it would not accelerate at all. I had to turn the car off and then back on again in order to get it moving. The gears continued to shift violently. However, when I finally got moving again, the car would not go over 35 MPH. The car was inspected and an error code for the internal speed sensor came up, which is part of the valve body for the transmission. My car only has 59,000 miles on it. Mercedes is very aware of this problem on 2006-2007 c230 models! In fact, they are having a dispute with the manufacturer of the valve body because it is poor quality and defective. I have seen numerous other complaints related to this issue. My local mercedes dealership quoted me $2,400 to repair this defective part. I was lucky in that I was not driving at 60 MPH on the highway when this malfunction occurred. This is an extremely dangerous issue and a recall should be issued for this part.

Took our daughter's 2006, c230 mercedes benz to our mercedes certified mechanic to repair a sluggish problem that caused the check engine light to come on.. I was informed that a part in the engine called the balancer was going bad... The cost is an approx $5000.00. And that we would have to take it to the local mercedes dealership to do the repair. The part installed in the 2006 and 2007 models was made of a too soft a metal, so its a defective part to start with! This part apparently causes the engine to lose power while driving... Benz has not issued a recall on this part.

My 2006 mercedes c230 has a defective balance shaft. I did some research and multiple people are having the same problem. There is a class action suit in the works. I believe this is a defective part that needs to be recalled.

Having problem with the gear shifting, believe this is caused by the shaft balancer, etc. The car grabs and jerks from time to time making me unsure of the safety of my car. My car only has 84,000 miles on it. The car is like new, but as I read the class act against mercedes I noticed that my car has several of the same issues as others listed in the complaint. The interior and exterior of my car is in excellent condition, and I can't believe that the mercedes company would allow an error like this to continue. I would like for this to be corrected by mercedes or to be placed on the class act suit as well.

Periodically the car would lose acceleration and rpms would be high and the vehicle would jerk when I tried changing gears. As I change gears from park, reverse or drive, the gear shift jerks and I am unable to accelerate past 20 MPH no matter how much pressure I place on the gas. : extreme loss of acceleration up hill and the steptronic (+/- shifting) did not work... (I could only go 35mph when every one else was going 70mph up hill) when I traveled on a flat surface with no inclination my car worked fine, I then decided to put it on neutral while traveling at 65mph...when I put it back in drive it did not pick up the gears it just continued as if it was in neautral. I had to pull over and shift it into park...as I shifted form "d" to neutral it shifted fine, but then from neutral to "r" the car jerked...from reverse to "p" it jerked again and shifted hard. I then shifted again to reverse, neutral, and drive thus the car jerked and did a hard shift with knocking noise and would not drive. I shifted to neutral again and shut the car off. When I turned it back on it shifted smooth and I drove off without any problem. Took it to a repair shop and received p0717/p0718 fault codes and something about the valve body. I was also told that it was an transmission internal speed sensor issue. There is something faulty with the design and operation of this model year transmission and losing power and being able to only go 35 MPH no matter how much you press the gas on the interstate or heavy fast moving traffic is extremely dangerous. Mercedes benz is aware of this problem as many owners have complained but they will not institute a recall.

After having the check engine light come on, we took the car to the dealership we purchased it from to perform a diagnostic after receiving codes p0170 and p0173 (mb codes 2092/2096) which mb classifies as "mixture in right / left cylinder bank is too rich when idling" and were told we would need to replace the intake manifold for $2110. The explanation we received (verbal only as they refused to describe the problem in writing after asking multiple times) was that a bushing that controls the air flow valves was worn. They could not provide a reason as to what would cause this wear considering the bushing is internal to the control valves. They also could not tell me which specific side this leak was coming from. Since the intake manifold is one large component we would need to replace the entire thing. The car is five years old so roughly just over 12k miles per year and already major components are failing. This is from the same dealer (mb georgetown, texas) who once told us our brakes (rotors and pads) were all bad and needed to be replaced. We took it to a trusted mechanic and only needed to replace the front pads as they were getting close to being worn out. We now need a second opinion since I simply do not trust them. The information they provided was "provide estimate to replace intake manifold for vacuum leak at $2110. Air leak coming from intake tumble flap assembly."

The vehicle was being driven on interstate 95 in pompano beach florida, the car started to run rough and the check engine light became illuminated. Took the car to the repair shop and it came up with 2 codes 1200 and 1208 intake and exhaust camshaft sensor right cylinder, the mechanics replaced the 2 sensors and a couple weeks later it appeared again. The original mechanic recommended another shop that specialized in mercedes. I took it there a few weeks later and we were informed it is a common problem with the mercedes and that they were being sued for it,and mercedes has put out over 10 tsb on the issue and it has been happening to cars with this new engine. The problem is the sprocket on the balance shaft was not hardened metal,like it was suppose to be.

To whom it may concern. I have the mb c230 2006. I've been losing power while driving. While the car idles it's running as if it's missing like out of timing. I've been to the parts dept because I was told the vehicle was missing. I had the coils changed. Spark plugs changed, yet still the car has no power and when idling the engine runs so violent it's causing the belt to wear. So far I had to buy 5 belts and they won't last more than 4 days. This past week I was also told that the 4 magets would have to be changed. Well I had them changed and still I have a car that has no power. I was finally told by a md mechanic my problem with the car is there's a balance shaft that's inoperable. When I inquire about this item I was told that mercedes benz does not have this as a recall item when in fact this issue has been an issue since 2004. I would like to have any information in regards to repair. There is no way a customer of this auto maker should have to bear the burden of paying for an item when in fact it's been a problem with mercerdes benz from the start.

I was driving my vehicle on the highway during morning rush hour when I noticed that the car would not accelerate over 35 MPH. I moved the car off the highway and stopped at a red light. Once I stopped the car it would not accelerate at all when I stepped on the gas. I had to put the car in park and then move it back to drive to get the car to move. The car would jump and lurch forward when I shifted gears. I drove the car directly to the dealer. The mercedes dealer told me that there was a problem with the software and that the software would need to be updated. I went to pick up my car after the "software " was updated ($1,700 cost) and drove the car about 10 miles when I noticed that the check engine light had come on. I took the car back to the mercedes dealer to let them know the check engine light was now on. The mercedes dealer told me I have a defective balance shaft that needs to be repaired. The mercedes dealer ask me if I had kept up the oil changes on the car. I told the them that I had. The mercedes dealer told me that I have to pay $2,500 just for them to take the engine apart and that the total repair will cost around $6,000. I just purchased the car in july 2010 ( 14 months ownership) with about 19,500 miles on it.

On march 12, 2011, during an "a" service, I was informed by my mechanic, the check engine light was illuminated due to the left intake cam sensor was defective but it was not a big concern. On september 17, 2011, during a "b" service, my mechanic stated the check engine light was illuminated again for the left intake cam and the right exhuast cam adjuster magnets were defective or the balance shaft was worn. At this point the car was running ok but he said if he runs a diagnostic test on the engine again in the near future and it reads a second problem on the right side cam side, there is a strong possibility teeth on the cam spocket due to the usage of an inferior product. He explained it would be approximately $4,000.00 to repair, he was repairing a vehicle with the same problem and showed me the wear on the teeth which cause the inbalance of the shaft and the cams come off line. In my mechanics opinion, mercedes benz knows about their defective part byt they do not want to have a "campaign" to resolve the issue and my type/year engine was made with this inferior part. I travel 80 miles to and from work and cannot afford to spend this money for a repair on a vehicle that is suppose to last me forever.
