I have a 2021 Accord Touring, around 14k miles, and today there is about 1" of slushy snow.

On the way back into my neighborhood where there is a small incline the car just stopped dead in its tracks and started flashing the TCS icon on the dashboard. would only move a few inches , if that.

I turned the car off and back on, disabled the TCS and tried again, same issue. It struggled so hard to do anything. Finally, with the TCS disabled, and a lot of stuggling i was able to inch up the hill. At this point I smelled some slight rubber scent as if I was likely spinning a wheel pretty good somewhere.

I maneuvered down the road (seemed to be driving fine at this point) to my driveway that is about a 20 foot long driveway, tiny incline up to the garage. Same issue, couldn't make it. I put the car in park and it decided to roll the entire way off the driveway, even with the brakes 100% applied and/or pumped. I shoveled out some tracks and salted it down and finally made it into the garage.

I sure as hell hope this isn't normal? I called the dealership i bought it from and they are going to have me come in so they can diagnose. Is there anything specific I should be hoping they find or any questions i should be asking if they DON'T find anything?

Hoping someone with some prior experience can be of help.

Thank you, and happy holidays!

30 degrees is not a small incline. It just sounds like you didn't have any momentum to get up the hill and the traction situation wasn't great.

I just kinda ballparked the incline in my imagination it may be less than 30 degrees. It's certainly not anything any car should be having trouble with. and while i might agree with you in a one off scenario. it happened again on my tiny little driveway and then it rolled off the driveway while in park?

It can't just be a no momentum bad traction situation. I hope.

I mean, did it slip off? ie the wheels weren't moving. Or did it actually roll off? ie all the wheels were all moving?

it was in park, brakes 100% applied, rolled backwards off the driveway.

edit* I see what you're asking...I don't know if it slipped or rolled. good question, I am not sure in the moment i was just trying to get it to stop.

I'll say this- odds are your 2021 Accord Touring came with 19" Michelin Primacy MXM4 tires. Those are completely useless in pretty much any kind of snow. I drove my Accord (with those tires in that size) once through very light snow and immediately realized that I needed a set of more snow-friendly tires for winter.

Those 19" wheels and tires are gorgeous to look at- but the tires that Honda uses for them are not suitable for any kind of snow other that maybe a slight dusting- especially as those tires start to wear.

There are quite a few different threads within this sub-forum that talk about suitable alternatives. I bought a set of 17" OEM wheels online for pretty cheap and put a set of Michelin CrossClimate2 tires on them- and they performed much, much better in the winter. In spring/summer/fall I put the OEM 19" wheels and tires back on.

If you have those Michelin MXM4 tires on your Accord- that's likely your main problem.

As @RCarlL points out, tires play a large role in starting traction. If you're in a location that gets significant snowfall, a set of tires rated with the severe service emblem (the three-peak-mountain-snowflake symbol) are necessary. If you're in a location that gets only mild winters, then a better set of all-seasons than the Michelin Primacy MXM4 tires that Honda ships with the vehicle will stand you in good stead.

On my Accord (with 18" rims), I run Nokian WR G4 tires. When faced with a snow-covered incline, I'll also shift into second gear to start - it cuts torque, limiting wheel spin. If it's steep enough, I'll also cut the TCS system out of the loop temporarily, and then re-enable once I've ascended the hill. But I can't understate the importance of good tires - with my FWD coupe and good tires, I've zipped up snowy hills that SUVs on all season (no season) tires were struggling to get up.

If you had the brakes 100% on it slid down the driveway. No traction with those tires and a very light engine over the front tires..
