Best Prime Day car maintenance and accessory deals

For most of us, the fun part of owning a car comes from driving it. For some that means the act of driving itself, for others, it’s the freedom to go wherever you want. The less-fun part comes when it’s time to maintain or clean our cars. But technology to the rescue — whether it’s diagnosing a Check Engine light or pumping up a flat tire, there’s an easier solution now than ever before and thanks to some sweet Amazon Prime Day deals, those solutions are cheaper than normal.

Here are our favorite car maintenance and accessory deals from Amazon Prime Day 2021, which ends tonight. Keep checking back throughout the next couple of days for other slick deals as they go live.

Chemical Guys

We’re big fans of Chemical Guys products around these parts. If you need proof, just look at all our car care product best lists. You’d be hard pressed to find one that doesn’t include a Chemical Guys item on it. And it’s a great time to stock up on some car detailing supplies with a ton of Chemical Guys car wash kits and detailing equipment on discount during Prime Day.


NOCO is no stranger to Roadshow’s best car battery chargers list and as luck would have it, a variety of its battery charger and jump-starter models are on discount for Prime Day. 


When it comes to rotary tools, nobody is better known than Dremel. These small, but mighty tools are an absolute must to have in the garage because you never know when you’ll have to cut, grind, sand, or polish something small during a car maintenance adventure. In addition to that, there’s nearly an endless number of chores these things can help with around the house. And these rotary tool kits are up to 39% off for Prime Day.


Some enticing Craftsman garage goodies are on special for Prime Day including a great pancake air compressor set (which can also be found on our best air compressors list), rolling workbench, 102-piece mechanics’ tool kit and a heat gun. Note some of them are already out of stock.


Gas station air compressors suck. They’re gross and usually take spare change to make run and who carries a bunch of change around anymore? Save yourself the hassle and get a small, portable air compressor like this one. It’s great for keeping your car, motorcycle, bicycle or trailer tires pumped up and won’t take up a ton of trunk space. Also great for off-roaders who want to air down for the trail.


If you’ve been holding off on picking up a new GoPro to record track day footage, now would be a good time to pull the trigger with this Hero8 Bundle available at a 44% discount. It includes the camera, two batteries, a 32GB SD card, a short tripod and head strap. Unfortunately, it doesn’t come with a suction cup mount to get exterior car shots, so remember to pick up one of those, too.

Black & Decker

A handful of Black & Decker’s 20-volt Max cordless drill kits and various yard tools, for when you must do some work outside the garage, are marked down for Prime Day. 


DeWalt fans will want to take advantage of the Prime Day with discounts of up to 30% on things such as mechanic’s tool sets, LED work lights, impact socket sets and grinders.


Unlike other OBD2 scanners we’ve featured for Prime Day, this dongle connects to your iOS or Android-powered device. It can do the same kind of code scanning and clearing as other devices and on some vehicles, it can provide additional sensor data directly to your phone. It’s pretty cool and something that you can just leave plugged into your vehicle all the time.


Everybody needs a good tire pressure gauge and no, those little stick ones you get from the gas station don’t count as good. This digital gauge from AstroAI does, though. It will read up to 230 psi which is way more than any of you should be running in any of your tires. It’s got a long neck which makes it perfect for RVs or trailers or just for not having to bend down so far when checking your pressures.


If you’re anything like us, you love watching people detail super-dirty cars on YouTube. It’s just so dang satisfying, particularly when they break out the foam cannon and make the car look like it got attacked by the Stay-Puft Marshmallow Man. Now you can experience the unmitigated joy of owning a foam gun on the cheap, without the need for a pressure washer. Do it and be happy.


If you’ve got a car built after 1996 and you are trying to save some money, owning an affordable OBD2 scanner like this one from Launch is a must. Not only does it make it a lot easier to diagnose what’s wrong with your car, it can also be used to clear pesky Check Engine lights. This one is a no-brainer.


When you live in a place that gets hot — Southern California, for example — having a sunshade for your car can mean the difference between a nasty seatbelt burn and a pleasant drive. They’re awesome and if you get a folding one, they take up very little space. This unit from Econour should do a fine job of keeping your car cool and your interior from being damaged by the merciless sun.


An impact wrench is a must-have tool in a garage that makes zipping off rusted suspension fasteners and lug nuts off a cinch. If you don’t have one, there’s an excellent Porter-Cable unit on special during Prime Day for $55, which is a cool 32% off regular price. This 1/2-inch drive example packs a stout 450 pound-feet of torque, which should be more than enough grunt to take care of every car maintenance obstacle you encounter. 


Extension cord reels are great, so you don’t have to work within 3 feet of a wall outlet, and this Goodyear unit is a really nice one. It features a 40 feet of commercial-grade cord with a triple tap light-up connector, adjustable cord stopper, breaker button and 135-degree swivel mounting bracket. Normally priced at $210, it can be had now for $120, which still isn’t cheap — but this is a truly premium cord reel that’s very well liked by users, boasting a 4.7 rating out of 5 on Amazon.


OBD2 scanners are amazingly powerful tools that used to be the province of mechanics and people with extremely deep pockets. That’s no longer the case, and this scanner from Autophix is proof of that. It’s got all the features you need for your 1996-and-later automobile and will make doing your own repair work significantly easier by removing a ton of guesswork.


Backup cameras, which became a requirement by law in news cars during 2018, are handy to make backing out of parking spots and driveways safer. If you have an older car and don’t have one, you’re in luck because there are several good aftermarket solutions available like this Auto-Vox T2 kit. This wired system projects crisp imagery onto an included rearview mirror, is liked by customers with a strong 4.5 rating out of 5 on Amazon and is available now at a 32% discount.


If you don’t want to worry about a battery going dead, this corded Cherylon Car Vacuum option is for you. A 16.4-foot cord provides plenty of slack to get reach throughout your car’s cabin and comes with various attachments to help get into every nook and cranny during car detailing missions. 


Car interiors — especially on daily drivers — get gross. It’s just one of those incontrovertible facts of life. Luckily, they don’t have to stay gross or get so bad you need professional help. One excellent tool to help keep crud at bay is a cordless vacuum cleaner. This li’l guy from Audew is perfect for getting dirt and old French fries out of your car without breaking the bank. Don’t be gross, buy this.


A selection of Gooloo portable jump starters and power packs are on special during Prime Day, ranging from 1,200-amp units to 4,000-amp versions for those who may need to get a big truck cranking. 

Five Bananas

Tired of wrestling with a C-clamp when compressing brake caliper pistons during a brake job? If so, the Five Bananas Brake Caliper Press Tool will make that chore substantially easier. A center ratchet screw distributes even force across the push boards to properly compress pistons without causing damage. It’s a slick, Roadshow-approved tool that can still be had for $23, which is 26% off list price.


The ability to charge at Level 1 with a normal 110-volt household plug is basically useless in most electric vehicles these days. Their battery packs are so big that it can take days of being plugged in to get even most of a charge. Level 2 chargers are better, but most require an electrician to install them in your home. The Splitvolt charger is different, because it plugs into an existing 220-volt plug (like you’d use for your clothes dryer) and then into your car. It’s also more affordable than most wall-mounted chargers.


Old, streaking windshield wipers are terrible. If your ride is rocking tired wipers, check the Prime Day deal for Aslam windshield wipers. They are highly rated with a 4.6 rating out of 5 based on more than 6,000 user reviews and available at a discount of up to 50% depending on size. Included with the blades is an additional set of inserts, meaning you essentially are getting two sets of wipers here.
