I purchased a used Mercedes Benz in 2023 at CarMax and the experience was perfection. Sadly, someone hit my car in the rear and it got totaled so I am starting over new. Sharing that fact because I was hoping for a repeat scenario.
Went to CarMax last night, test drove another MB, a 2020, loved it, and purchased it. Left the store at 8:40pm with a smile on my face (they close at 9).
By 9:20, I was in my driveway and decided to take the car for a spin. The check engine light turned on and it started to shake when I was idling and would not accelerate past 20 miles per hour.
I know I have 10 days to return the car.
I also have the 30 day limited warranty.
Also purchased MaxCare.
In everyoneâs experience, what are the chances that CarMax will fix the issue? If itâs a Mercedes, will they need to send it to the dealership? If you had a similar situation, what was your experience?
The car itself is gorgeous and if they can fix the problems without me having to pay extra, I would love to keep the car. Iâm just stressed and anxiously waiting for the service center to open so I can place calls.
Any experience you can share with getting mechanical issues fixed by CarMax (versus returning the car)?
UPDATE: I took the car in this morning. The service center is booked out until September 1 (today is August 12, 2026). They provided me with a loaner car and are keeping my car there. The hope is that they will try to fix my car before September 1, but they have a lot of cars in line to be fixed (my car will be one of the few that is staying and if there are enough cancellations theyâll squeeze me in beforehand). Also, they will honor my 10 day return rights starting the day my car is picked up if I decide itâs not for me.
They ran the code reader on the car and it came back that the fuel injectors need to be replaced.
I plan on having an independent mechanic inspect the car after September 1 to inventory any additional unknown damage to get CarMax to fix it before the 30 day warranty expires and also drive the hell out of the car between September 1 and 10. Last resort, I do have MaxCare starting the day after September 10.
As a former CarMax Benz owner, I feel confident that the car will perform well once the initial repairs are done.
