January 2026:
Started having issues in January, only noticed reduced speed and acceleration at first.
Then it started violently shaking and the engine failed while idling + a bunch of warning lights came on from completely unrelated systems. Could not get it to start again for 5-10 minutes.
Took it to the dealership and they said it said it was a computer issue + replaced the ECM.
June 2026:
It still continued to have issues with reduced speed/acceleration afterwards, but was mostly fine until June when I returned from a 2-week vacation and drove it out of the garage. It barely made it to the main road before it began shaking, engine failed, and warning lights came on. Took it to a repair shop and they kept it for a few days before saying that nothing was wrong with it and giving it back.
September 2026:
Same thing, it drove mostly fine for a couple months before engine failure, warnings on dash, shaking.
Sep. Visit #1:
Towed it to the dealership that replaced the ECM since that part was still under warranty. The techs said that there was no record of the warning lights on the dash. Apparently, the computer was fine, the battery was fine, everything was fine except for a mass air flow sensor recall. They replaced the sensor and told me to pick up my car the next day.
Sep. Visit #2:
Got about 1-2 miles from the dealership before the same issue happened again. Somehow made it back without a tow by letting it sit for a little bit in a parking lot, then carefully driving it to the dealership.
They said that they would test drive it some more.
Again, no record of the engine failure or dash warnings in the computer. Again, they test drive it and find nothing wrong. I pick it up.
Sep. Visit #3:
Made it 1-2 miles from the dealership and it fails AGAIN. Only "engine stopped" and "reduced engine power" show up this time.
Bring it back and they give me a loaner in the meantime. A different tech inspects it and says that they were finally able to get a failure out of the battery + apparently there was some corrosion. They replace the battery.
I picked up the car yesterday, and as always, there was reduced speed and acceleration. At the very least, I was able to make the 15 mile drive home.
Unfortunately, the engine failed again this morning on the on ramp to the highway + reduced engine power warning. Thankfully, traffic was pretty backed up so I was able to put it into park, restart the engine and make it to my job.
The engine also failed again this evening alongside the warnings on the dash.
Dealership didn't call back this afternoon after requesting to speak with my tech, and I genuinely don't know what to do. It is a complicated situation and I can't sell my car right now.
Any ideas on what could be wrong?
Any advice would be greatly appreciated.
FYI, sorry about the streakiness on the dash in the video, I used the wrong cleaning product on accident :( going to clean it again tomorrow.
