1 Automatic Emergency Braking problem of the 2006 Mercedes Benz E350

Failure Date: 10/01/2025

Mercedes benz issued a recall and extended a warranty on its 2003-2005 e class sbc braking systems (recall # 2005110001) and extended the warranty to 25 years; the 2006 e class models have the exact same sbc braking system but is not included in the recall. Mercedes needs to add the 2006 e class models to recall # 2005110001. My 2006 is experiencing the same sbc issues the 2003-2005 models are known to have but because my vehicle is 2006 it is not covered by the extended warranty.

2 Automatic Emergency Braking problem of the 2016 Mercedes Benz E350

Failure Date: 10/08/2024

Yes, it is available for inspection upon request. The instrument cluster showed some messages* randomly appearing/beeping on and off but there were other issues present: • acceleration not possible in drive • at one point transmission would not shift from gear 3 • *speedometer would go up and down randomly until it eventually stayed at 0 physically and digitally as I was going 55-60 mph • *check engine light on • ‘brake’ light on • failed • *distance sensors failed • *stability control failed • *electronic braking system failed • *power steering failed • *cruise control failed • *mercedes pre-safe failed • *blind spot assist failed • *lane keeping assist failed • *adaptive highbeam assist failed • *mileage was not displaying on the dash • car would not shut off as I pushed the off button when I managed to eventually stop • *climate temperature sensor reaching temps of 127 degrees fahrenheit. I lost control of the vehicle while driving on the highway at relevant speeds. I was unable to safely stop for some time. If this had been at night, the issue would have been even more dangerous. This car has previously slammed on the brakes erroneously (no visually perceived danger of a forward collision). These previous brake slamming issues happened once in a traffic jam on the highway and once on a main road. Not that I know of or remember, no. Before this latest incident, I have previously left my car at the dealership’s workshop to be inspected for some relevant issues and concerns that I have had. It was there for almost 2 months on one occasion. There was only one warning lamp on the instrument cluster related to the collision prevention assist being inoperative. This message has been on the dash for maybe a year or more. The times it previously slammed on the brakes erroneously, no messages were on the dash.

3 Automatic Emergency Braking problem of the 2012 Mercedes Benz E350

Failure Date: 07/06/2024

I am writing in regards to the 5 vehicle recalls that were for the make, and model of my car that is showing as having no recalls for. The recalls involved air bags, air bag software, fuel filter flange, and I am also wondering with the driver headrest deployment module if that is associated with an airbag module; as when I had purchased the vehicle I had found out that both my airbag modules had malfunctioned with showing the srs lights on the dash. I was told that mercedes of sarasota, FL had replaced the passenger airbag module by mercedes of south orlando. When asked for a printout verification of this repair showing to be completed; they said they couldn’t provide me with this information. As proof of the service to being completed could not be provided. I had tken my car to their to have them look into this, and the tpms sensors showing malfunctioned; communication error message, and they couldn’t figure out what the problem was causing this. I had to take my car to an auto electrician to find out the problem; that I had found out that a 100 amp fusible link had blown, causing all those problems with also the roof wasn’t working. Along with I was smelling fuel. I found out about the recall for these items after getting them repaired out of pocket by the auto electrician mike from peak audio, and electric, and as to the fuel filter flange I had to pay like $1,200 to replace as they had replaced the fuel level sending unit that include the fuel filter flange. I would like refun; still have the headrest driver side that needs to be replaced. I found out that their is an recall for this make, and model of car that had said the air bag deployment software was under recall for those vehicles; which I believe could have triggered the deployment of the head rest while I was driving; as if I had been near a car; I could have been involved in an accident. I think that this should have an open ticket for repair placed on all 2012 mercedes E350 cabriolet blue efficiency.

4 Automatic Emergency Braking problem of the 2014 Mercedes Benz E350

Failure Date: 07/12/2022

Vehicle is 9 years old, with 73000 miles. Dealer service has advised that the rear subframe and brake lines are rusting and need to be replaced as a safety issue. Cost quoted was $8800. Mercedes agreed to pick up the cost of the parts and the dealer offered to split the installation cost, bringing my total down to $3150. On-line research reveals this is a common problem across several product lines and has been an issue for 20+ years. Failure at this point could lead to uncontrolled movement of the the rear suspension structure, the rear suspension members, wheels, and electronic sensors in the abs causing loss of control and brake failure.

6 Automatic Emergency Braking problem of the 2013 Mercedes Benz E350

Failure Date: 08/21/2021

Pre-safe inoperative warning message comes on at random times. I’ve taken the vehicle in to address this issue, but mercedes claims they did not see the message, and there are no error codes. I purchased this vehicle because it comes with this safety feature - I find it unacceptable that it does not function.
