Power Control Unit Failure on 2017 Smart EQ

[Sokrates_MR]

I’m dealing with a tough situation with my 2017 Smart EQ fortwo and hoping someone here might have some advice or experience to share. My car has only 8,000 miles on it and has been my trusty commuter in San Francisco since I bought it in 2021.

Recently, I got a flashing red light about the 12V battery failing, but I kept driving it for about a week. Then, the red brake light flashed, and the car completely died. The dealership is telling me the Power Control Unit (basically the car’s brain) has failed and quoted me an outrageous $17K to fix it, more than the car is worth!

I feel stuck. Has anyone dealt with a Power Control Unit issue on their Smart EV? Were you able to find a more affordable solution or repair option? Maybe a third-party repair shop or refurbished parts? I’m feeling so frustrated and lost right now.

I’d contact Smart’s customer service directly, especially since your car has such low mileage. Sometimes, manufacturers will offer goodwill repairs or discounts for major failures like this, even if the car is out of warranty. If that doesn’t work, definitely look into independent EV specialists or even online marketplaces for refurbished PCUs.

I’ve heard of a few people having better luck sourcing parts from Smart-certified mechanics or EV recyclers. It might take some calls and patience, but there are shops out there that specialize in repairs for these high-voltage components. I’d also try reaching out to Mercedes-Benz customer service to see if they’ll offer goodwill assistance since the mileage is so low. You never know!
