My 2014 SMART FORTWO has a HV System Maintenance warning that should be included with 2014-2015 HV System recall that Mercedes has. However, My VIN is not coming up on the search. The HV System is causing the car to not charge correctly at charging stations and it is causing the system battery to drain. I don't know when the HV System light came on, but it started causing the vehicle to glitch about March 05, 2025. I have someone look at it in 2023... But it is still having HV System Maintenance problems.

My SMART ForTwo Coupe 2014 has been having a High Voltage System Maintenance alert on the dashboard. I have sought service help from AAA and PepBoys, but everyone was saying the system battery is fine. When I moved to an apartment that doesn't have electric outlets, my ability to charge was stifled. When my HV battery went under 10%, the system battery shutdown and the HV battery went into reserve mode. I searched the internet and all over the U.S. SMART ForTwo 2014 is having this problem. It's all over the forums on SMART USA website. I did a search and Mercedes has a recall for SMART 2014 - 2015 coupes and convertible with HV System errors. But when I search the NHTSA website, my vehicle did not come up. I've been told in my local city forum that on Mercedes Dealer can fix this problem. So, many SMART 2014 is having this issue. How do I get service help if my VIN isn't popping up for HV System Error? I highly believe my HV System error is related to the following below. Please, look into the HV System Maintenance error that SMART ForTwo ED 2014 is having nationwide. You can find the error reported on YouTube, Facebook, SMART USA, and so many places. The Following is the Recall Quote on Google: "Mercedes-Benz USA (MBUSA) is recalling certain model year 2014-2015 Smart Fortwo Coupes and Convertibles, and 2014 Fortwo Coupe Electric and Fortwo Convertible Electric vehicles due to a potential high-voltage battery failure that could cause the vehicle to stall and increase the risk of a crash or fire.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Smart Coupe verdict →
