I have a 2021 GLA 250 and my engine light came on then went off. A few weeks later the engine came back on and I scheduled an appointment at dealership. Well, the cylinder head fail and I'm now riding in a loaner. (21k miles) I'm leasing the vehicle but want out of the lease and placed in another car because I do not trust this SUV on the road. Can I get out of lease?
welcome to the forum. sorry to hear of your problem.
Theoretically, yes, but unless you're trading into another Mercedes (and likely a more expensive one), they are either going to make it a tough process or charge you a penalty. My parents have always leased cars (except a few), and they have gotten out of the old lease a month or two early, but only because they were trading to another model and the payments would just be applied to that car ( like a store credit).
You can try and trade into a different MB and hope they go easy on you (or not charge), or see if another dealer will take it on trade (likely below market value tbh). Legally speaking, once you've signed a lease contract, you're obligated to pay the full amount you agreed to, regardless of whether or not you keep the car for the full lease term. Most dealers would rather avoid making enemies by having customers shell out the whole amount, so they move the lease to another car, or get you to buyout the current one and trade-in. Also check the Lemon Laws in your jurisdiction, maybe you can use those to your advantage. Hopefully MB or NHTSA recalls it by then.
IMO, you have nothing to be concerned about safety-wise. once they've fixed the car, you should be good to go. If it happens again, then I would talk to the GM at the dealer and see what can be done to find a different car.
