2014 Smart EDElectrical system

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.

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...

2016 Smart EDElectrical system

2016 Smart car passion key stuck in switch. Stationary in park gear. Poor design of shifter, if that easily disabled. Should be recalled and replaced with improved design shifter. If that sensitive why do they put 2 cup holders near the shifter? Simple rubber seal would fix it! The service mechanic said the shifter was damaged because of a coffee spill - how long does it take - because any stain was years ago when I got the car. I have not drunk any in the car over a year. To save money I make coffee at home and...

drink at work. I'm sure all this summer wet and humid weather caused a problem. After weeks of rain the key was jamming many times before it got stuck. I think the shifter was defective and failed and should be replace for free. Internet search shows the shifter is common problem for this car. Trying to blame a spill for the failure but just a bad shifter. This is the second smart car I have gotten and the most trouble. I can't afford the estimated #1100 cost to fix it.

Engine light flashed briefly and went off. Within one mile engine lost all power. As I slowed to a stop, a large cloud of steam erupted. Car was in shop for over a month and most of the engine was replaced. No explanation of lack of warning lamps. A second two week trip to the dealer was needed to resolve all the issues. Car still has engine light on
