I picked up a 2016 CPO S-550 last Thursday (Valentine’s Day gift for my wife). However, 5 days later I’m thinking about returning the car under the “7 day/500 mile satisfaction guaranteed” clause.

To be honest, I was a bit skeptical from the beginning because:
1) The car had 2 previous owners
2) It was involved in a minor accident (according to CarFax, there was minor damage to the front and back of the car but the airbags were not deployed)
3) During the test drive, the left turn signal wasn’t working. This raised 2 questions.
1. If they missed the malfunctioning turn signal during the CPO inspection, what else did they miss?
2. Why is the turn signal failing so soon? Could this be residual damage from the “minor” accident?

However, I ignored my concerns because:
1). The car is certified so any issues would be covered by warranty
2). It was a low mileage car (21,000 miles) with quite a few options (not often found in this region)

Yesterday, I noticed coolant on the floor of my garage. The dealer repaired the leak by replacing the coolant hose. When I asked if it was odd that a hose would fail in a <3 year old car with 21k miles, I was told that premature coolant hose failure is a known problem with these cars. However, looking through this forum and other web sites, I couldn’t find any owner comments that support the dealer’s claim. In the back of my mind, I’m wondering if this might be another problem that stemmed from the “minor accident”.

I have approx 36 hours to make a decision on returning the car. However, the policy states that I would have to buy another car of equal or greater value. The reality is that they don’t have any other CPO cars in stock that interest me. There are a couple of new S560’s in the dealer’s inventory that are equipped to my likings. However, even thought I’m eligible for the 12.5% employee relative’s discount off of MSRP, I really don’t want to spend $100k+ for a car.... especially under these circumstances.

So my question for this forum are:
1). Have you heard of premature coolant hose failures in these cars?
2). Would you be inclined to suspect that this car will be problematic over the next few years or would you place your trust in the CPO warranty?
3) Any other thoughts/suggestions?

7 day, 500 mile satisfaction guarantee, yet you still have to buy a car of same or equal value? Does not seem like a satisfaction guarantee to me? I would ask to see the General Manager of the dealership to discuss your concerns and gauge the possibility of returning the car with zero obligation to purchase another vehicle.

I would walk, no run away from this since it’s cover under the 7 days guarantee. Accident from carfax and 2 owner car with low mileage is a indication that the first owner didn’t like it after the accident and second owner didn’t like it either.

Accident where airbag didn’t deploy only means ( to me ), the insurance company wasn’t really to total the car.

Get out of that car today and would suggest not buying a car that has a carfax accident.

Good luck.

Ted Moreno/GM and Mike Daniel/Service Director of Ontario Mercedes are great people and very customer oriented. If Ted promised you something, he will come through. Ask Ted provide you the VMI ( service history ) of this car do you know what was actual done to the car and the accident.

Have you tried FJ Newport, they have a great selection?

Anyone that does not live in NYC but has traveled there knows this to be true on repainting bumpers. Probably everyone repaints bumpers due to the tight parking spaces and the way people drive. I see that some people put on those “rubber bumpers” on top of their manufactured bumper to avoid all the scrapes and scuffs.
