Bought a New Mercedes and before Delivery of Car, Dealership Damaged a Module in The Car by Jumpstarting It

Hi All

I've paid the whole amount to buy a new Mercedes. The car was already as a show car in the showroom and salesman told me that the battery went flat because it was standing still in the showroom, so after my payment cleared and it was time to register and deliver the car. They came back saying a module in the car was damaged and had to be repaired which would take a week or two, and this happened because someone jumpstarted the car and damaged the module.

If I wait for the car to be repaired and take ownership of it, god knows what other faults might be in there that probably haven't been caught for now. If something goes wrong with the car in the next few months, I'd always be thinking whether it was this event that caused the issue.

Companies always try to wriggle themselves out after delivery with warranty repair, by saying this and that isn't covered in the warranty.

Now this is a new car that the dealership damaged by jump starting it? What would you do? Buy the car or ask for a refund?

I should mention, salesman seems nice and genuine and was upfront about what happened so obviously thankful to him for letting me know.

Also, they aren't asking me for any money to repair it obviously.

    It's brand new. You have warranty if something goes wrong. You bought a Mercedes, love them, but (expensive) gremlins come with the territory. First hand experience.

      Not sure why so many people saying ask for a refund. The OP won't get a new car until 12 months later.

      Just get them to fix the module. If there was major damage across the rest of the car it most likely won't work at all, it's a yay or ney answer. Most of the time it's just an apprentice doing the boring work like charging the batteries every now and again.

      They will most likely replace the battery too but I doubt it would be damaged anyway as there would be fuses and other interlinks inbetween to stop that from happening, like said module.

      They're fantastic cars, will always have issues, just deal with it. I would think a mercedes has twice as many parts as a toyota but it still drives a lot nicer than a toyota.

      If you're going the mercedes route, just be ready to accept small things that go wrong. Mercedes have always fixed major things for me inside and outside warranties.

      They're all human beings, just treat and expect to be treated as such and all will be fine.

      Many of the people here saying ask for a refund probably haven't been in the car market recently, it's literally a free for all, take what you can get.

        Yep, unless the op has the luxury to wait until 2023 for a car then take the car and deal with any remaining issues under warranty.

        I’m looking for a new car at the moment and it is a patience game. Most of the delivery dates are end this year or early next year (and I’d I expect they would blow out once the order made) and some are 12 months or more.

    Something doesn't smell right. A Mercedes dealership employee damaged the car, by not knowing how to properly jump start it?

    I guess it doesn't matter if it was damaged beforehand though - they need to fix it either way.

    My concern would be not knowing/being able to check if other components have been damaged. I mean, how are you going to test if the Autonomous Emergency Braking works? Drive at a wall?

    • try2bhelpful on 18/05/2022 - 14:58
      +2

      Yeah, that would be my concern. Certainly my old Merc had an issue with flattening the battery if left sitting; but you would think a Merc dealer would know how to do this properly. They don’t recommend jump starting modern cars because you can fry some of the electricals. You are meant to trickle charge them back up.

      Me, I’d be talking to them about another car, however I suspect this will involve a, considerable, wait. Also you don’t know what has happened to that car either.

      • ausdday on 20/05/2022 - 10:26

        Interesting they feel they need to jump start the car, while the car is still in the dealership. They could just walk into storeroom and bring out a new battery I suppose?

      MB dealership employees are not more capable than your average workshop employee.
      Dealership changed the battery in my MB and (a) used wrong size battery in replacement (b), left the insulating cover off the battery terminal and c), only closed the bonnet to the safety catch position position. Noticed the latter when the bonnet started flapping around when doing 100kmph on the freeway.

      “how are you going to test if the Autonomous Emergency Braking works? Drive at a wall?“

      They’ll use a code reader to check via the car’s onboard computer, same as we do for every other similar situation in the world. Do you think they pre-crash aircraft too to check the emergency landing systems?

        The battery "reset" just tells the car a new battery is connected, so use a "new battery" charging profile. The car adjusts the charging profile as the battery ages.

        It will work even if you don't do it, but the battery lifespan may or may not be shorter. You do not have to tow the car to replace a battery.

  • apsilon on 18/05/2022 - 14:59

    I share your concerns with what else may be damaged. Even if it hasn't failed right away it could have shortened life span but on the other hand you do have warranty.

    I've walked away from 2 cars that were damaged in pre delivery and probably would in this case as well though new cars are hard to come by in the current market. If you decide to proceed ensure they put in writing what was damaged and how so if further electrical gremlins raise their heads in the future you can point and say it's had X problem caused by the dealer which might help speed up warranty claim (but probably won't).

      More like a a common misconception. Euro cars can be jump started just the same as any other car. Just need to be particular in how you connect and disconnect the leads. Have owned Mercs & BMW's and jumpstarted without issues.

      What? No you do it in the same way. The terminals just aren't directly accessible on the battery, the negative and positive are normally in the front bonnet somewhere as the battery is often in the boot.

    • quasio on 20/05/2022 - 11:26

      This doesn't seem right. all electronics are tested and validated to ensure it can handle jump start. Even jump start at 48V (in case someone accidentally uses a truck jump starter), reverse polarity, everything. However you should use the correct jump start points to do it.

      Although i also know that if its a brand new merc with new platform, there's still a ton of bugs, so it's more likely the software for that module couldn't handle it.

    If the battery was so flat that it wouldn't start the car, then that battery is already dying, so they were hoping to give you a battery that is already stuffed instead of just replacing the battery. Gives you a bit of a hint as to how they will treat you if you need warranty repairs.

    • Domicron on 19/05/2022 - 14:16

      But it is a new car? Battery in one of my old car worked fine after a 6 months trip overseas.

      Not sure how a new car can have a battery flat before delivery, and we have a "shortage" here with cars flying out of the dealership doors.

      I am also curious as to what caused the flat battery to begin with.

      • AdosHouse on 19/05/2022 - 17:25

        I suspect the new car has some sort of parasitic drain, but with all the news features with new cars, especially higher-end Euro cars, I'm not surprised.

        • Domicron on 19/05/2022 - 18:50

          Well, mine was a Cooper S, also on the S3 as well. Nothing high end, but idle consumption shouldn't be too different. The cla250 has two batteries, one for aux.

          European cars do come with a higher capacity battery in general.

          Again, still not adding up as there are rarely any cars in the showroom there days. Doubt they would have been sitting there for long.

          • AdosHouse on 19/05/2022 - 20:01

      If the battery was so flat that it wouldn't start the car, then that battery is already dying, so they were hoping to give you a battery that is already stuffed instead of just replacing the battery.

      That is not necessarily true and is pure speculation.

      It's far more likely they left the car accessory power on or some interior lights or something. That doesn't mean the battery is dying, and a jump start is enough to bring the battery back.

        When a battery gets below its working voltage the plates start degrading, how low it goes and for how long determines the damage. Sure you might be able to bring it back, but the life has been cut.

    They should have one of those plug in trickle chargers for cars they leave in the showroom for this exact reason, secondly they should just have replaced it with a new battery.

    They have either put the jumper on the wrong connectors or they have done some major damage to the electronics and or systems. You do however still have the full warranty and could haggle to have it reduced for their consequences and you being put out up to you in the end

    100% nobody blew up a module jumpstarting it. My bet is on the fact that another shitbox came in for an issue and the part was 4 to 6 weeks ex-Germany, so they cannibalised the showroom vehicle to get the part now and put the ordered one onto your car.

    Just get a refund because you will never be happy and will use this as leverage for anything that goes wrong with your car and will end up being a pissed off customer over something that is a non-event.

    But just so you know, you wouldn’t believe the shit that gets done to new cars between the factory and you being handed the keys. I have seen cars literally crashed in the holding yard and then repaired and sent out to dealers as new vehicles.

      They are very easy vehicles to cause damage to when jump starting if not done correctly.
      i see it all the time with mercs.
      they have a module in the boot that would blow just by showing it a set of jumper leads
      this is based on previous models, no experience with current model however some things never change.

      I was gonna comment on this and saw you've already done it.

      I had such a good laugh!!

      With respect your comment is most unfair.
      I'm sure the salesman was nice and genuine and even offered the buyer a cup of coffee while giving a super deal to the OP.
      It's people who don't understand sales techniques who give these poor individuals such a bad name.
      I seem to recall Alan Bond had a close friend who sold cars and look what a fine individual he was.

    Who knows what is wrong with the car that prevented delivery? As mentioned above, it could well have been a donor for another failed Merc and they have just mentioned to you that it was a fried module.

    Where is the car now?
    Is it still in the showroom awaiting the new module?
    Is it in the workshop? Or,
    Is it a complete lie and the car is in the panel shop after an over zealous apprentice caused body damage?

    Considering the big? bucks your are spending on a new Merc, for peace of mind I would refuse delivery of the car and seek a refund.

    You can not simply jump start modern vehicles… I surmise the vehicle is now damaged

    • MontyMacaw on 19/05/2022 - 16:15

      Agree. I would be forever worried about what would come next. It would dive me crazy. The nature of electrical issues is not always about where the fault occurred but how much further the charge went before it stopped.

    Who in their right mind thinks jump starting a vehicle with a flat battery is going to recharge the battery?!! The only solution is to use a different battery or fully charge it safely.

      What makes you think they were trying to charge it? They were probably trying to move it.

        Same applies 🙄 I bet mummy had problems with her little Skylex being pedantic.

          That doesn't really answer my question, so you just made it up out of nowhere then I take it.

          If the battery is flat, they would likely charge it, or replace it, but they would hardly do that in the showroom. They would need to move it. Did you imagine their cunning plan was to jump start it in the showroom, then leave it running until the battery was charged?

          You can call that pedantic if you like, I just find it ridiculous that you could somehow come to that conclusion. All the while proclaiming some sense of right mind superiority.
