2014 Mercedes-Benz E350 driver assistance problems

Filed Jul 24, 2026 · Brakes, Driver assistance · OH

The failure was when I hit the brakes hard in an emergency braking situation and the car very eratically and violently veered to the left. There was no warning and thank God there was no car coming in the left lane otherwise it would have been a broad side hit. I was doing 55 mph. We had the car inspected at a local shop and the left rear tie rod link was completely severed from the suspension sub-frame because of rust. The brake lines above the sub frame were also severely rusted and leaking. I called my closest dealer and they said the rusted frame replacement is covered under extended warrenty but not the brake lines which had the same issue, severe corrosion and a potential catostrophic failure! Mercedes Road Side Assistance was called to tow the car 70 miles to the closest shop.

While driving, the steering from left to right started to get choppy or hard. With the cruise control on, I ran off the road because of the fight between the rack and pinion(steering wheel) and the cruise control.

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.

Intermittently, while driving several of the electrical systems will fail including the lane keep assist and abs. When this happens, it also causes the instrument cluster to rapidly change speeds, making the vehicle unsafe to operate as the driver is unable to tell what speed they are going, which can become extremely hazardous since this happens at random. The issue has been diagnosed to be a faulty Radar Sensor in the rear bumper, however the specific part has been on backorder since February 2022 and Mercedes-Benz has shown no signs of urgency with resolving this issue. I have a video of the ongoing hazard that I can submit as well, it's just too large to attach to this form.

My steering wheel will not telescope up/down. I have had this repaired 2x's in the past 3 years. 5/2017, 6/2018, 8/2019, 12/2020 additionally, the blind spot assist notification goes off when there's not a car around me. Typically happens when I'm driving and go down a slight decline in the road.

08/13/2018 when I was driving home today steering and brakes failed for like 1-2 minutes and I lost control.. Then all the instrument warning lighting started to flash continually the temp gauge and RPM was in motion. Srs and all pre safe functions malfunctioned I can send an video of this if there is a way to upload. I think this is a serious safety issue what if I lost control on a highway, even for a split seconds. Why I bought a mercedes I thought its a safer car well that's how they advertise it the best or nothing. But that couple of minutes was scary and shocking for me

My claim # is10691110 the lane control does not function consistantly. Sometimes when you cross a line, the rear brake on the opposite side of the car automatically applies bringing the car back to the center of the lane, other times it doesn't. I demonstrated this to the maintenance mgr. With no satisfaction. I've discussed with a case mgr on several times, with no satisfaction. I've written the pres of mercedes on two occassions, who referred my concern back to the same case mgr. Who says it is functioning as designed,in spite of the fact I demonstrated to the dealer maint. Supervisor that it doesn't.I asked for a regional person to ride with me so I could demonstrate the inconsistancy of the way it functions. I was denied my request. The federal safety agency seems to be my only hope for getting my safety concern resolved for me and any others who may have the same problem. The problem was demonstrated on state rt. 33 in dublin oh. With painted road lines that were consistint. I have many notes of additional detail if wanted.
