New Mechanic Swapped My Wife’s Engine?

[Cx5wifescar]

I brought my wife’s car to a new mechanic. It was supposed to be a quick job. Oil change, tires, and brakes. They kept the car for two and a half days. Said they couldn’t get to it. (They had a lot of cars there, they even had to park cars across the street)

When I picked it up the engine felt different. It starts fine. But when I put it in reverse or drive slow, it feels off. Sluggish. The response is not the same. I’ve driven this car a lot. Something is not right.

I looked at the engine block. The number stamped on it is PE1022007173.

The car is a 2016 Mazda CX-5 GX AWD. The build date on the door sticker says April 2015.

I started researching. People say Mazda engine serials go up over time. If that’s true, then this engine might have been built after the car. That would mean it was swapped.

Did they actually switch the engine while they had it?

Is that even possible?

If anyone here has a PE engine with a number close to PE1022xxxxx, and knows what year it’s from, I’d really appreciate your help.

I need to know what happened. My wife is going to lose it if I tell her what I think they did

Highly unlikely to swap the engine. Why would they even do that without your knowledge?

If this is for real you could contact Mazda corporate and give them the info. I'm sure they could look it up and verify.

They do a lot of engine swaps at that shop.. mostly Honda K swaps and I’ve seen some other engine replacements on their Instagram page. So that’s where my paranoia is stemming from.

I’ll call Mazda corporate on Monday.

I called the dealership but they don’t have any information.

Is the engine cleaner than your old one? That would be a giveaway. You should remember how dirty it was prior.

Swapping the engine is a BIG job. Unlikely they did it in a day, especially if they needed to source a donor engine.

Another thing - If I took my vehicle in for oil chg, tires and brakes and they called me and said they couldn't get to it for a couple days - I'll go get it and bring it back the day they could or find another shop.

Maybe the battery was disconnected for some reason and the ecu and transmission were reset to the default?

In terms of leaving the car there for a couple of days…We work from home and have two cars so we didn’t think anything of it. In hindsight I should have went back to pick it up.

check you harness christmas tree connectors...in order to do an engine swap the harnesses all need to be undone and impossible to get them all out without damaging some of the christmas tree ends..

Plus the motor mount bolts and such would show clear signs of being wrenched. Still begs the question of “why?”.

No need to panic. Doubt they swapped the engine. But Here is what to do

go to a local Mazda dealer service dept and ask them to print you :
warranty vehicle inquiry report.

It does show whats the engine number and I believe this is what you are looking for. My 2018 shows it on that report page.

Dont mention anything about engine swap etc as its irrelevant for your request.

Just ask for the report. Give them the car registration to show you are the owner of this car/vin.If the car is in your wife name go with her.
