On [XXX], while driving on the highway about 30 miles from Columbus, Ohio my 2013 Mercedez Benz ML350 suddenly stalled and lost power. There was no prior warning. Luckily, we were in the outer lane with no car close behind us so my husband slowly guided the car to the side road. The car has since been towed and is currently at the Service Department at Mercedez Benz of North Olmsted, Ohio, 44070, for repairs. I have been informed by the Service Manager that they have identified the fuel pump to the problem and that it needs to be replaced. Coincidentally, this vehicle went for Maintenance Servicing at the same dealership and was returned to me on Monday December 16th. No problem with the fuel pump was identified or reported to me. This vehicle is available for inspection About 4 years ago, the exact same incident happened with this same vehicle where it suddenly stalled and completely lost power on the highway in the middle of nowhere on our way from Ohio to Iowa. There was no prior warning. Similarly, the car was towed to Mercedez Benz North Olmsted but per the same service manager their inspection revealed no problem and the car restarted on its own so nothing needed to be fixed. I am reporting this recurring problem with my vehicle because of the obvious safety risk of sudden stalling and power loss on the highway, the fact that 4 years ago when this happened Mercedez Benz should have recognized what the issue was and replaced the fuel pump but did nothing about it, and also due to the fact that many Mercedez Benz vehicles have experienced this same problem leading to multiple recalls including many 2013 ML 350s. I believe my vehicle has a defective fuel pump from the manufacturer just like the recalled vehicles and that my vehicle and many more need to be recalled INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I participated in the Emission Recall Campaign 2020050014. I have a 2013 ML350BlueTec. I have been back to the dealer 10 times to fix my car after the recall was performed. The check engine continues to return in an on (orange light) position after only a few days. On trip 5 my car could not accerlate and lost power. The problem related to the NOX sensors that are being replaced each visit. MB USA replaced b19/9 temp upstream of turbo charger and b9/11 temperature sensor upstream of catalyst. Also remove and replace 3 temp sensors. Again, I have been back 10 times to the dealer for continual problems related to the recall. Since Nov. 29, 2021, the warning light (check engine) remains on and MBUSA does not respond to fixing it. MBUSA reported that there is a software issue they are working on. Can you help please?

Vehicle has 129,000 miles. When trying to accelerate from a stop, mostly noticeable when fuel is lower in the tank and/or on an incline, RPM drops to zero, no amount of pressure on gas pedal does anything until the engine speed picks up, usually with a jerk forward. Makes going onto a busy street very unsafe. Have read it may be software related.
