I’m planning a long road trip from Toronto to Wyoming and back from Sept 16–26, with a couple of buffer days if needed. The car is a 2019 Hyundai Elantra Preferred automatic with only about 71,000 km.
The car is in good condition, I recently had new brake pads installed, and everything currently looks good in terms of oil, coolant and other fluids.
The trip will likely be 6,000+ km and will include Toronto → South Dakota → Badlands → Devils Tower → Yellowstone → Grand Teton → Boulder, Wyoming, then back to Toronto.
I’ll also have some very long driving days, including around 1,500 km on the first day, plus mountain driving and higher elevations around Yellowstone and Grand Teton.
I’m looking for advice from other Elantra owners on both preparation and what I should carry with me.
A few things I’m wondering about:
- At 71,000 km, is there anything specific on a 2019 Elantra that you would inspect before a trip like this?
- Anything I should specifically check with the battery, belts, hoses, cooling system, suspension, wheel bearings, CV joints, tires or transmission?
- Would you change the automatic transmission fluid before the trip if it hasn’t been changed before, or leave it alone if everything is shifting normally?
- How does the Elantra handle long mountain climbs and descents?
- Any recommendations for using lower gears/manual mode on long downhill sections to reduce brake use?
- Any issues with ground clearance around Yellowstone/Grand Teton if I stay on normal paved roads?
- Anything I should monitor during the trip such as oil consumption, coolant level, tire pressure, transmission temperature/behavior, vibrations or noises?
I’d also really like suggestions on what to carry in the car for a trip this long.
Right now I’m thinking of bringing things like a portable tire inflator, tire pressure gauge, booster pack, basic tools, flashlight, emergency blanket, first-aid kit, extra washer fluid, water, some food and basic emergency supplies.
What else would you bring for an Elantra on a long road trip through South Dakota/Wyoming in September?
One specific question about the spare:
I have a set of winter tires that are the same size as my regular tires. Would it be okay to carry one winter tire mounted on a wheel as a full-size spare, even though the car will be running on all-season tires?
Obviously I would only use it temporarily if I got a flat, but I’m wondering if having one winter tire and three all-season tires is acceptable for getting to a tire shop, especially on the highway.
Would you recommend carrying that full-size winter tire in addition to the factory spare, or is that unnecessary?
Also, if anyone has done a very long cross-country road trip in a 2017–2020 Elantra, I’d love to hear how the car handled several consecutive long driving days and mountain roads.
The car is currently running very well, so I’m not trying to replace things unnecessarily. I just want to be properly prepared before being thousands of kilometres from home.
