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!

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.

I was driving on a straight away doing the speed limit which is reported seconds before the car crash. The steering wheel turned to the left really hard out of no where and wouldn-€™t let me gain control over the car again. I was sober it was 9am and I was aware of my driving. I ended up spinning out and landed in the ditch feet away from the light pole. I made it know to everyone what happened, but they looked at me crazy. I stopped driving that car and sent it back to Mercedes to get a detailed inspection. Which lasted about 30 days for them to get back to me about what happened. When I received the call to get my car they didn-€™t provide any information about the incident. Instead they just sent it to corporate and left me in the dark. I was in pain during this whole time. I was couldn-€™t find a lawyer that was willing to help. It-€™s been three years since the incident and I will have to live with pain for the rest of my life. It-€™s not fair that we need thousands of dollars to be heard. I have all communication and documentation that was given during the time of incident.

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.

Steering wheel malfunction. Car parked at garage and when I went to start I got the malfunction message and the steering wheel would not turn. I called Mercedes and they will tow the car tomorrow. For a brand new 2017 Mercedes this is unacceptable.
