Hey good morning. There-€™s been a been a system failure. P052E Positive Crankcase Ventilation Regulator Valve Performance. Warning message I got was the engine light showed

- Sharon, CT, USA

I was driving on highway I95, all the sudden, the vehicle shows, Power Steering Malfunctioning See Owner's Manual. I've lost the power steering in the middle of the highway. The steering was so hard and not safe. The next day, I've started the car and the issue isn't there anymore! Now the car is driving fine!!! Please, this need to be fixed, cause it may happen again, and that happens on a sharp curve, it may lead to a crash!

I was reversing my vehicle when I heard a snap, and the inside dash panel warning sign came on-€¦later I google it and found out it has happened to many other people. the clock spring behind the steering wheel snapped and airbags warning signs came on with possibility of deploying at any moment.

When I started my car, the dash did not reveal park, drive, or reverse. It illuminated with a warning light indicating an Electronic Stability Problem (ESP). Research revealed this to be an important safety feature and that the Mercedes-warning-lights-electric-stability-control may have problems with traction control requiring attention. The ESP light was NOT flashing for the system to intervene -€" as the car was parked in my garage. It did not light up with the word -€˜OFF-€™ to assess whether it may have been inadvertently deactivated. The light stayed on indicating a suddenly improperly working ESP system. The light remained on after stopping and restarting the engine several times as the dealer maintenance technician suggested concluding with my vehicle being towed to Mercedes Benz of Augusta for service. I am not sure if the MB mechanic reproduced the issue as they discussed several other potential failure points before resolving to replace an item in the steering control module. Experiencing this alert, I became more concerned that a safety inspection may not have been part of the last maintenance service. This is my third Mercedes and I make sure to keep up with all my maintenance. I had never seen this warning light before. Up until this time the only warning light I had seen in my car was for low air in my tires. My safety was not at immediate risk. I am glad my car was not able to be driven, as I would have hated for it to stop while I was out and about. I am a proud Mercedes Benz owner as they are world renown for the safest cars on the road. My car has just over 25,000 miles and it was unimaginable that it would have this kind of failure. I should not be held accountable to pay for a safety failure that I should be part of required maintenance checks. An additional periodic Mercedes required safety inspection could prevent this potential breakdown while providing another measure to protect the life of Mercedes Benz owners.

When the car is in the a feature, where it turns on and off when not in motion, it gets stuck in that mode as if a magnet is holding it in that position. It will not move, it stalls. I turn it off and turn it back on and sometimes it still will not move, sometimes, it will not turn back on. This has happened on several different occasions. Once, I pulled to the side of my mailbox to pick up mail, and another occasion I pulled into my garage, and it stopped, and would not turn on. This is very dangerous, I would hate to be in traffic, railway crossing, ir stop sign and this occurred. Peoples lives have been lost due to this issue. One lady was hit by a train when this same situation occurred and lost her life. I am very concerned for my safety and of my grandkids whom I Transport in this car. It also seems that something is wrong with the gears. Sometimes, I put it in reverse and it sits there. I put it in drive and it will not move. I feel very unsafe in this vehicle. Please help.

The 2017 Mercedes-Benz C300 vehicle suffered a complete loss of power/electrics while in motion at speed and in traffic, causing the vehicle to unexpectedly stop on two separate occasions. The loss of all electrical supply leaves the vehicle immobile, without warning indicators and cannot be moved. The first incident was around 5pm in a busy road junction in the dark, with limited lighting. As the vehicle is black colored it it is difficult to see in these circumstances. The second incident was at another busy road junction in heavy traffic, at midday on a Saturday. On both occasions the police had to attend as the immobilized vehicle posed a serious hazard with a risk of causing a collision to other road users. The approximate times to get the vehicle removed from the road in these two incidents were between 45 - 60 minutes. The period between the two incidents was 11 days. The day following then first incident, the vehicle was inspected by a Mercedes dealership, who had the vehicle in their possession for five days. Initially they stated that they had not found a cause for the loss of all electrical power in the vehicle. Subsequently when pressed on the matter, they stated the cause was a connection problem to the positive terminal on the battery. In good faith the vehicle was collected by me and driven without any apparent problem for four days, prior to the second incident. The mileage driven in that period was less than 100 miles in total. This vehicle poses a serious risk to the driver, passengers and other road users.

On 7/30/18 I was stranded in the middle of the street after the coolant malfunction light came on. The car began overheating, and there was no ac. I waited for roadside assistance more than 3 hours. I was informed of the incorrect positioning of the alternator from manufacturing, which resulted in multiple lights on cluster. They found the engine belt fell off & replaced the V-belt. They performed LI13.22-P-060187, and released stress of alternator and corrected torque. They also worked on a campaign/recall (#2018070005) I had not been informed of. On 3/15/19 during the scheduled 20K service, they tested battery test code with cabin filters wipers and brake fluid service and performed a vehicle inspection. On 3/19/19, 4 days after the scheduled 20K service, I was stranded in the middle of US1 during rush hour traffic on my way to work. The coolant light came again. Thankfully, I safely avoided an accident after the car turned off in the middle of the street. The report showed a weak crank & battery message on the cluster display. They tested the battery and found code hr250bt-dad4lfb stating, 'replace battery'. they removed A0019820208 date 45/16 and installed A0019829108 date 03/18. The drive belt had come off the drive system & found LI13.22-P-060187, which stated they needed to perform an alignment procedure of the alternator and installed a new belt for the 2nd time. The belt actually caused damage to the tensioning device, which resulted in them replacing the tensioner, and performing the instruction for li. They test drove the car & said it was fixed. On 4/4/19, just 3 days after picking up my car, it turned off on my again in the middle of US1. The battery light came on and a message popped up stating that the system would shut down in 3 minutes. I was lucky enough to avoid an accident on a congested road.

Since I bought in February 2017 brand new 2017 Mercedes Benz C300 convertible in one year of ownership I had to bring my car several times for services like, the convertible top would not work, the mirrors would not fold, the steering wheel would not adjust, electronical issues like connecting my cell phone to the car. ( I had the top got replaced only after couple of months after I purchased the car.) today April 27 2018 I could not start the car in the morning to go to work, the display was showing the key is not detected( had to exit the car couple of times, with the key and try again to start the car until it finally worked).had my top open while was driving to work and once parked the top would not close, and again had to exit the car lock unlock an try again couple of times before if finally closed. I did receive a letter saying that the car was defefected, and that the airbag on the drivers seet may not work, I'll attach the letter ( brought for services) but it's seems that they didn't fix the problem. Also the tire pressure every couple of weeks it's low, and the display would show sometimes that the seet is not firm or steady. I bought a brand new car to feel safe and do not feel that way.
