Got them at Costco because I’m dull.
But on the way home my car went into limp mode with a check engine light and a computer error light.
Called Costco and they said “we just did the tires” but when I reset the system by disconnecting the battery the traction control, power steering, and tire pressure lights came on.
And it’s still in limp mode.
Taking her to my guy later today.
Thanks Costco.
ETA: Turns out my coil packs and spark plugs went bad, it was just a coincidence that it happened after the tires.
ETA II: My guy said the spark plugs were all the wrong kind.
No costco nearby, but usually get tires at Sams. Walking around the store gives me something to do while I wait.
That’s what I did too. They had an amazing deal on pork butt but I can’t justify more meat until I run out of brisket
I have learned that some cars operate better with specific kinds of spark plugs. At some auto stores or mechanic shops, they may try to upsell you on better kinds, and for a lot of vehicles you do get what you put into it. However, on occasion for some cars, you actually will make things worse with those more expensive plugs. I had a car once where the upsell was always iridium plugs but they literally were worse than the cheaper ones and recommended to avoid for that specific motor.
This can also happen with gas. Some cars should never get higher octane fuels. Like some cars should only ever get 87 and no higher.
Really depends on the vehicle and unique needs of the engine. Usually the book will explain this or hardcore dedicated forums about their maintenance.
Also, buying your own OBD II code reader for like $30-50 can sometimes do wonders. I’ve had one for a decade now and when stuff goes wrong it is nice to be able to look up codes immediately and at least get some information or a vague idea on my own.

Theres no benefit to using “premium” gas in a car that doesn’t require it. Higher octane prevents dieseling in a high compression engine. It does nothing in a regular engine, it’s just an additional additive you don’t need.
It has a custom exhaust and intake so I wouldn’t be surprised if the previous owner put in “performance” plugs which then wore out the coil pack.
I have my own Bluetooth code reader but funnily enough my mechanic had it because he put his reader on it and accidentally left it in the shop. So I picked it up when I got my car today.
I just joined and visited Costco for the first time this weekend. I also cancelled my membership the same day.
Not worth all the hype, but the hot dogs are pretty good.
I’ve been getting tires there for years because it’s almost always the cheapest and they do a decent job.
An Irishman on YT has me convinced they broke a wheel position sensor.
And I didn’t even get a hot dog
Wheel position sensor? News to me, but I’ve been out of a garage for over a decade.
I know that the TPMS (Tire Pressure Monitoring System) sensors are REEALLY easy to break, and not always in an obvious way.
Of course, you’re relying on a sensor that spins around at high rates of speed, often gets bumped into potholes or hit curbs, vibrates through all of it, and would be considered replaceable within the industry. It isn’t the cheapest trip to the shop, but its cheaper than four new tires if that is your issue. Also, your techs can EASILY break one and not know it during normal operating procedures, though usually that was due to guys prefer brute force as the main thing in their tool box so your experiences may vary - I worked with some morons back then, lol.
I’d imagine they mean wheel speed sensor which is used by the ABS/traction control to detect which tire is slipping/locked up. Usually just a magnet that reads high/low spots on a ring of some sort.
Ahh, that makes sense. I figured it was something I was just unaware of, even when I was in the shop I didn’t do much more than basic maintenance type tasks for the most part.
In my case the wheel position sensor is also an indirect TPMS, because a low tire will rotate faster
Costco is pretty far from my house, so that was a major factor when we decided it wasn’t worth making that trip once a month.
I only ever use them via Instacart and for tires. Though maybe not even that anymore.
If you have a gift card they will let you in, even if the gift card doesn’t cover the whole purchase.
Possible that your car has a special procedure for lifting if it has air suspension. May also need some kind of calibration after having tires installed or one of the tires is the wrong size.
I thought that because of how the tire pressure sensor works but there’s nothing in the manual about it and no Internet search turns up results.
