Leased a Mercedes EQB300… now stuck paying $800/month for a car they admit they can’t fix
I’m honestly at a loss and would really appreciate advice from anyone who has dealt with something like this.
In December 2023, I leased a brand new Mercedes EQB300. Everything seemed fine at first, but by September 2024 the car started having serious issues — the instrument cluster (speedometer/navigation) would randomly go completely black while I was driving.
Not glitchy… completely black.
In November 2024, I got a “Coolant Too Hot – Stop Vehicle” warning related to the high-voltage system.
Since then, it’s been a nightmare:
- Multiple service visits
- Repeated “no issue found” responses
- Full dashboard removal to replace wiring
- Replacement of major components
- Software resets and updates
And the issue STILL happens.
In March 2026, I was told there’s basically no fix yet and that one might come in a future software update.
Then in April, I spent 3 hours at the dealership trying to resolve this. We even got to the point where:
- A replacement car deal was discussed
- I called my insurance to add the new vehicle
- They updated my Mercedes app
…and then suddenly they came back and said they couldn’t cancel my lease.
On top of that, every time I had a loaner, I was told I had to drop everything and return it immediately or I’d be charged ~$150/day.
Meanwhile, Mercedes-Benz Financial Services sent me a formal letter stating that I am legally required to continue making my ~$800/month payments under any circumstance, including if the vehicle is defective, unsafe, or even destroyed.
The letter specifically references the lease agreement and states that payments must continue “even if the vehicle is stolen, destroyed, or does not satisfactorily perform,” and that any issues must be taken up with the manufacturer.
So now I’m stuck in this loop:
- Dealer → “talk to manufacturer”
- Manufacturer → slow/no resolution
- Finance → “keep paying no matter what”
To make things worse:
- The car has a high-voltage battery recall
- I can’t charge it safely at home
- I’ve read charging restrictions in some places
- I have a young daughter who depends on this car daily
I feel like I’m being forced to drive an unsafe vehicle while paying full price for it.
