1 Engine And Engine Cooling problem

Failure Date: 08/28/2024

The engine in these cars are defective and can cause serious harm due to a part that was put inside the motor made of plastic. There was a lawsuit but if you didn’t get in on it you losses out for not knowing. I was recently at mercedes dealership to fix recalls and they brushed me off. The car can catch fire and I’m already experiencing engine failure after only owning the car for a year. They don’t care because it’s an old car but it’s still being sold to unsuspecting buyers. I’m not the only one there are thousands of us who are at risk driving these cars because mercedes won’t admit their off the showroom floor mistake.

Failure Date: 12/30/2023

Certain mercedes-benz models 2005- 2007 m272 v6 and m273 v8’s have faced or are facing issues regarding the balance sprocket in which drives the camshaft and crankshaft of the vehicle. Mercedes-benz had made a decision to make certain engine components out of soft metals, when such metals are not adequate in handling the stress of the engine. In particular, in many cases, the balance sprocket was made with inadequate materials and gradually deteriorated to the point in which it could not engage the timing chain and cause camshaft-crankshaft misalignment. I personally did not experience such failure yet but it is more of a concern as this is a common issue , the repair is quite substantial and the failure can damage the engine even more.

Engine codes p0016 and p0017 reads cam shaft and crank shaft correlation it is everywhere on the internet and on the Mercedes Benz forum. This is a know problem that mercedes has ignored. Its on all 2004 thru 2008 vehicles with the 3. 5 engine. Calls for a balancer shaft replacement. This should definitely be a recall issue. The industry knows that is was poorly manufactured part. Your help with rectifying this issue would greatly help the and restore the reputation of mercedes and restore faith in Mercedes Benz owners. My vehicle is a 2006 E350 4 matic with only 113,634 miles.

4 Engine And Engine Cooling problem

Failure Date: 11/23/2022

We just purchased a 2006 mercedes for our teenage sons and had a dealer look at it before we purchased it. They told us there were a couple of codes that were worth watching but that it wasn’t anything significant right now. After the car started jerking and shaking while driving it, we brought it in to dealership where they told us it had a common code for mercedes in this timeframe p0016. Repair estimate is nearly $5000 to replace timing chain and balance shaft, or a new engine which would be roughly the same. After researching on my own upon being told this code, I found all of the information about the class action lawsuit and settlement, which of course we are too late to be a part of. The dealer said there is a potential that the car could just seize up at some point, so I don’t want my young sons to be out on the road when that happens. I am very frustrated and upset that this wasn’t a recall since it apparently affected a huge amount of vehicles manufactured within this time frame. There is a specific list of engines with known issues and ours is among them. Mercedes benz should be held responsible for making this right because it was definitely a quality issue. Now we are stuck with an unsafe vehicle, or a massive expense due to defect.

5 Engine And Engine Cooling problem

Failure Date: 06/20/2022

Driving the vehicle on several occasions on interstate 66 and the vehicle spontaneously went into limp mode. Now we find out it's a balance shaft issue and is a known problem from mercedes in the m272 engines for our 2006 E350 4-matic. They evidently used balance shafts with materials that were too soft, resulting in premature wearing of the balance shafts with all of the m272 engines produced during this time having the problem. There was a previous class action lawsuit, which mercedes settled, however, the consumers were not adequately notified and no recall was ever issued for the cars. Now we have 2nd or 3rd owners having these problems that didn't get a notice and have no idea there is a huge expensive and dangerous problem with their vehicle. On I-66 traffic moves at 70 mph (regular lanes) or 75 mph (express lanes). Having the vehicle spontaneously go into limp mode because of this engine issue is dangerous and could have caused a fatal accident on multiple occasions for us. Mercedes should be recalling all of these engines and fixing them properly before someone gets injured or killed. When I spoke with mercedes, they said because I was not involved in the class action suit at that time, they were not willing to fix the car or pay for any portion of the repair, which they quoted me as costing $16,228. 96. The problem is the mercedes went into limp mode on multiple occasions and there was no check engine light to indicate what the problem was for several months. We had no warning that this was going to happen which created a dangerous situation while driving. There were several incidents on different dates spanning months before a check engine light came on with codes and mercedes could identify the problem specifically was the balance shaft failure.

6 Engine And Engine Cooling problem

Failure Date: 06/01/2022

Balance shaft issues possible cause of vehicle stalls and safety concerns.

7 Engine And Engine Cooling problem

Failure Date: 05/30/2021

The crankshaft pulley is a two piece item. When excessive pressure is on it the pieces separate and disable the car. Upon replacing the belt or belt tensioner more pressure is exerted on the crankshaft pulley. Thus it fails and again disables the vehicle. When doing either of the replacement tasks mercedes fails to check this or mention it to customers. Thus months later it fails and previous belt replacement of belt tensioner replacement has to be done again. This creates a dual expense without fixing the issue the first time. Expense is in the thousands.

Balance shift worned.

24 Engine And Engine Cooling problem

Failure Date: 05/01/2013

About a year ago (may 2013) we noticed gas smell in the compartment of the car. Initially it was sporadic. We thought it was from outside of the car or may be under the car, or gas tank cap was not tightened properly. After I took my car to Mercedes Benz dealership on 9/6/13, I found out that the smell was not from either of the above scenarios. It was indeed from inside the cabin and the Mercedes Benz technician told me that it was from fuel leakage under the back seat and it would cost $1380 to fix it. Additionally he said that he had seen numerous cases like mine, and some were so bad that they would not be able to drive it in, and had to tow the car in. Because of the high cost in addition to the other repairs that I had to do worth $1,200, I decided to delay this repair. Now we can not even drive the car because of the intense smell and will cost me probably more that $1,380 to fix it. I believe strongly that this is a manufacturer defect and should be fixed and paid for by Mercedes Benz.

25 Engine And Engine Cooling problem

Failure Date: 03/13/2013

I initially had issues with the transmission slipping then there were engine issues compounding the problem. Re the transmission, my first occurrence was when I was about to enter a very busy intersection and my car would barely move. My mechanic explained later that the car was stuck in 3rd gear so I could not get my normal forward movement. He told me if it happened again to turn my engine off, count to ten and turn it back on. Fortunately he told me this because the next times it happened I was on Lincoln blvd. In marina del rey, CA. And my car would not accelerate at all. One time I was at a red light so had time to turn it off and on. The next time I had to coast into a very small center divider that was growing smaller and with traffic flying by on my side and oncoming I had to turn off my engine, count to ten and turn it on. This caused a lot of angst since I had cars flying by and at me while doing this. There have been many other instances. I am getting no cooperation from mbz.

26 Engine And Engine Cooling problem

Failure Date: 09/17/2011

Engine/transmission was acting jerky and suddenly the car lost power to engine and the car broke on it's own doing causing the vehicle to swerve into the other lane. Luckily there were no cars behind or to the side of me as this would have surely caused an accident. Currently there is a class action law suit in place specifically to the engine in my car and the part at fault.

27 Engine And Engine Cooling problem

Failure Date: 07/25/2011

The "check engine" light on the instrument panel came on. We took it to the dealership for maintenance and asked them to diagnose the problem. We were told that it was associated with a faulty balance shaft and that it needed to be replaced sooner than later or else it could cause entire engine to stop working when it failed. The quoted price for repairs was around $5500 with a $1000 discount. Once home, we researched "faulty balance shaft on 2006 Mercedes Benz E350" and found the first website to have information of a class action legal suit in progress against mercedez benz over defective balance shaft gears in Mercedes Benz m272 engines & idle gears in Mercedes Benz m273 engines. It was disconcerting to realize that a vast number of people have experienced the same problems without getting relief from mbusa. It is unacceptable to see that so many people are experiencing the same issue of defective engines from a manufacturer who commands a price premium for its "superior engineering" and yet does nothing to correct a serious and widespread fault. From the various reports, including those in the lawsuit website and online forums, mbusa has failed to assist customers with these issues, in most cases citing that vehicles are past warranty coverage and therefore the owners must cover the cost of repair. This is unacceptable since it appears to be a factory defect, rather than "wear and tear" that the customer is responsible for. Mercedes benz must pay for this problem, not the customer.

2006 Mercedes Benz m272/m273 engine. *balance shaft issue* our 2006 E350 Mercedes Benz was just diagnosticed that it needed the balance shaft replaced, a $5000-$8000 dollar repair.

Faulty balance shift and idle gear. Replaced many components to rectify the issue only to find a star bulletin was available for the fix. Original found while vehicle was under warranted and technician failed to fix. Now that car is out of warranty, will incur a 6k fix on what seems to be defective or substandard parts (balance shaft sprocket and the timing chain guide wheel(idler).
