Very Unprofessional Experience with BenzNinja


Here is the history. I bought a car and did an inspection that shows two issues. The rear camera cover would not close, and the trunk partition flap would not operate. He updated software for the rear SAM and other modules. It did not fix the problems, but it added a new problem. The gas flap would not open.
After he reverted the software to the original version, the gas flap would open. But now, there were two new problems. The trunk and glove box would not unlock. Both open with Xentry actuations, so the hardware is fine.
When I complained that he made my car worse, he became rude and aggressive. He berated me while saying how great he was. This was not a one-time thing but rather ongoing and pattern behavior. I just ignored it in the past. But this time it was much worse. He was outright insulting me and calling me stupid. Then, he said that the only way he would continue is if I agreed that he would not be responsible for the results. I said no. Because if he breaks it then he fixes it.
He refused to fix what he broke and said to go to the dealer.
I told him I want my money back. He agreed to refund but first he wanted me to send him the latop and hardware and give him remote access to my laptop to check the system date. That seemed fishy. Because I bought the hardware on eBay so why should I return it to him? Given how badly he is acting, I suspect he was trying to trick me. I confronted him with this. He admitted he would have wiped out the laptop.
He kept on saying how great he is and how everyone is so happy with him and I am the only person who has ever complained. Ever? I am sure there are satisfied customers. I was too until he broke my car, refused to take responsibility, insulted me, and tried to trick me. This amounts to bad faith business practice.

With any repair, things happen. God knows if a mechanic looks at an M157 a freaking water line may break. Many things can happen. As for his refund policy? Heck, I would have the same. You have his TANGIBLE items. "Work Product" has no real value beyond the skills of the person providing it. His tuning things? Yeah, I would get them back, verify functional and then look at a refund.
I am not sure what country Peter is in (or State). But, becareful - slander is tough battle to fight. You done and went openly public about it BEFORE you even attempted to send his things back to him.

What the hell does a gas flap have to do with the CAN? Ever consider you have a failing CAN? While I am only inferring what I can only imagine your voice on the phone must be like....judging by your thread here...I would have probably hung up on you as well.
Note: I am not a BenzNinja customer - I know a few. None have ever had your venomous behaviors. All of them know that sometimes **** happens. Maybe you should have taken your car to the dealership? Lesson learned? Go to the dealership next time (they would not have touched your car).

Here is not the case as the SW that this guy install on club members is "made by him" although is not and is even is copyrighted.

This post is about Peter's conduct. On one hand, I didn't want to post this because it does not help me. On the other hand, if he is talking down to me and resorting to trickery, he is probably doing the same to others. Maybe this will make him stop and treat his customers better.

There are a couple issues: 1) His SW update broke this. I ask him a simple question, where can I toggle this setting? Rather than answer the question, he insults me and tells me he is so smart. Why not just answer the question? Why is such a simple problem taking days to be addressed and still not being fixed? Why is he complaining that I am taking up so much of his time when he is the one who broke it and can't fix it? 2) Regardless of the technical issues, you don't abuse your customers.

I also want to summarize part of our private messages. He told me he had no responsibility to fix anything because it was a ‘club’ and not a business, even though I paid for a membership that was advertised as including remote diagnostic help. He also said he would wipe my laptop as part of a refund. The laptop is my personal property, and I purchased the hardware myself on eBay, so I didn’t understand why either of those things would need to be returned to him or erased. That raised concerns for me because I didn’t know what recourse I would have if he wiped my computer and took hardware I bought independently, and then still refused to issue the refund. I’m only sharing my personal experience so others understand why I felt the way I did.








Based on what I know - BenzNinja is an expert. Period. Based on what I assume, he does not "need" your money. It is a pastime/second income / hobby of sorts. If he has a remote job, great, if not - I get the feeling he has a ton of hands on things (that pay higher per hour).
With what I do, I am an "expert". In my job I have low tolerance for people who do not want to do things the correct way (not just my way, the correct way). I had a kid who asked a TON of questions, seeminly stupid questions...ticked me off every time. My stand point was "just do it and do not question"...maybe, just maybe this is his stand point (SoupNazi???).
To that, we are all (everyone of us on this forum) so blessed. Even those who struggle wtih the finances and repairs and ownership - we as humans are so blessed. We get to play with great cars, a great communiity and great comroderie. 90% of the humans on this planet have no access to the internet...let alone discussing on if my trunk camera flap is going to open if I pass gass while the left turn signal is ajar....




Mr. Scallawalla, after reviewing those messages, there’s no place where he insulted you. That claim simply isn’t backed up by the conversations. From what I can see, he also spent close to 20 hours updating and configuring modules on your car, work that no dealer would do without charging thousands of dollars.
It’s also worth mentioning that this was done to help fix a camera issue; the problem later turned out to be a broken gas flap mechanism, where the flap motor was no longer attached. In the end, the main concern seems to be that the gas flap works now, and that you don’t want to go back to your local dealer because they’re no longer willing to work with you.
Taken together, this tells the full story.
Have a good evening. A very happy club member!
