Should Dealer Charge Diagnoses Fees on CPO Cars?

Hello everyone,
I am new to the forum. I just purchased a CPO 2016 AMG GLA45 back in August. After a month of ownership, I notice three issues:
1. Brakes pulsating with noise a highway speed (the brake force is adequate though, and there is relatively decent amount of pads and rotor left)
2. Squeaking noise from the steering column
3. The first button underneath my recaro seat (driver side) seems not working properly. It is making sound, but nothing happens when pressing the button.
I purchased this car CPO from a dealer that is 30 minutes away (MB of Alexandria), but decide to go to my nearest MB dealer (MB of Silver Spring) for diagnosis and repair. However, after i describe these problems, the service guy was saying: CPO might not cover this... CPO might not cover that... you should bring the car back to the dealer you purchase from...blablabla... And most importantly, they said they need to charge me a diagnose fee of 190 dollars since the car is out of the original warranty.

I feel this is unreasonable since my limit CPO warranty suppose to cover most problems during the first year. My last car was a certified Cadillac ATS-V and I never have to pay a diagnose fee when I brought the car to the dealer.

So my question is: Does all Mercedes Dealer charge a diagnose fee for CPO cars? Is this dealer trying to rip me off? I appreciate your help! Thanks!

They’re really not in the wrong.. just do yourself a favor and don’t expect extra service coming from the dealer just cause you bought the 3 pointed star.. you could try to see if there’s any AMG performance centers nearby because they usually have a SA or two that’s truly about the brand and will go above and beyond but most SA’s have to deal with water pumps on C300’s all day and just want to go home and not think about Mercedes anymore.

The dealer I use does the same thing.. charges a diagnostic fee initially, but if CPO covers it, the fee gets waived. I’d assume it’s probably a similar case for yours.

1. Brakes won’t be covered by CPO, they’re ‘wear and tear’ and excluded.

2. Squeaky steering column sounds like something CPO should address.

3. Does the other switch on the Recaro behave differently? You should have two, one for thigh and one for torso bolstering.

CPO is supposed to give you one year added to the original warranty. The new car warranty is four years, and CPO makes it five years from when the car was put in service the first time. The brakes are stuff. Is it due to wear in one month, or is it a factory defect? The original dealership might look at it as a defect as they just sold you the car a month ago, and the car should have been checked for brakes as part of the CPO. The other problems should come under the CPO warranty. It might be better to go back to the selling dealer.

I would get back to the selling dealer ASAP, long you wait, the question of wear goes in their favor.

Thanks. I ask Mercedes NA and the dealer I purchased from, got the same answer: If CPO covers specific repair then no diag fees.
I don't have hope in the brakes now, I hope they can address squeaks in the steering column. As for the switch, the second one (torso) bolstering works fine.

Thanks. I will bring it back to my purchase dealer next week if those issues aren't address under CPO.
The switch does not work, which should be covered by warranty. I do not understand why a diagnose fee is needed at your expense. It is up to the dealer to find out why the switch does not work and bill MB CPO warranty. The same applies to the Squeaking noise from the steering column.

Replace the front rotors yourself with genuine parts that you can buy from online dealers.
The other 2 you can bring to the dealer.
The bolsters control may be based on air bladders. So maybe the pump works but the air hose is off.

Thanks, the dealer end up didn't charge me anything. However, they didn't figure out anything as well. According to them, the switch does work, but it work in a very slow fashion.

I will definitely do my own brake since they don't cover it. The dealer didn't find anything bad with the bolster control either, they say it just work in a very slow fashion (They showed to me and I saw it moving, but very slow compare to the passenger side)
