2021 Toyota Highlander hybrid problems
The Toyota Highlander, also known as the Toyota Kluger (Japanese: トヨタ・クルーガー, Hepburn: Toyota Kurūgā), is a mid-size crossover SUV with three-row seating produced by Toyota since 2000.
Announced in April 2000 at the New York International Auto Show and arriving in late 2000 in Japan and January 2001 in North America, the Highlander became one of the first car-based mid-size SUV or mid-size crossovers. The Highlander is the crossover counterpart to the more rugged, truck-based mid-size 4Runner and became Toyota's best-selling SUV before being surpassed by the smaller RAV4 in 2006.
The first-generation model was sold in Japan as the Kluger, which was exclusive to dealership network called Toyota Netz as a larger alternative to the RAV4. The Kluger nameplate is also used in Australia because "Highlander" is a trademarked trim line name owned by Hyundai. The name is derived from the German word klug, which means smart or clever (Klüger – with diacritics – means "someone who is smarter than another" in German).

I recently purchased a 2021 Venza Limited, fully loaded, but after just 3000 miles, I realized it wasn't the right fit for me. Although it looked sleek in photos and had positive online reviews, the ride was too stiff and the road noise was irritating. I decided to trade it in for a Highlander Platinum, which I initially overlooked due to its family hauler aura and style. However, I was pleasantly surprised by its solid build, smooth drive, and ample space. The infotainment and technology are a step up, and the interior fit and finish is excellent. I appreciate the knobs and buttons, as I'm not a fan of 100% touch screens. As a semi-retired individual, I didn't think I needed the space, but I was wrong. The Highlander has plenty of power and gets good gas mileage. Overall, I'm very happy with my decision and believe that Toyota Hybrids are some of the most dependable cars on the road.

Hi there! I hope you're doing well. I wanted to bring to your attention that I've been experiencing a bit of trouble with the driver's side mirror on my vehicle. Specifically, I've noticed that it vibrates quite a bit, especially when I'm traveling at higher speeds. Unfortunately, this vibration makes it difficult for me to see images clearly, which is definitely a safety concern. When I brought this issue to the attention of the dealer and regional field rep, they informed me that this is 'normal for this model'. While it's possible that this issue may be present in other similar vehicles, I don't believe that it's normal or acceptable. Unfortunately, Toyota has declined to address this issue any further, which is disappointing. I'm now considering looking into the Lemon Laws to see if there's any recourse available to me. Thanks for your time and attention!

Driving on twisty two lane roads in moderately hilly country with very few stop lights can result in better gas mileage than the EPA rating, perhaps 3-4 mpg better. I live out of town on roads without painted lines and with only one stop light in the county I live in. With only a couple of fill-ups so far, I'm absolutely amazed at the gas mileage. The car rides smoothly, is a joy to drive, and is not noisy at all. For those complaining about engine noise and lower than expected mileage, they must be talking about high-speed interstate travel which I rarely ever encounter. I've made a couple of long trips on the interstate and achieved 38 mpg. My typical local mileage has been 39 to 41 mpg per tank. My other car is a 2028 Mazda CX-5, but I can't believe that I think the Highlander handles better. Maybe I need new tires on the Mazda? I've had my Highlander for 5000 miles so far and I love it. It has a smooth, gliding ride and handles turns unexpectedly well. I like driving it, perhaps more than my Mazda CX-5. It seems well-made and worth the money. I don't use the third row and have the platinum with captain's chairs. I never need to carry more than four people. I would like the third row to be removable. The only issue I have is with how fast forward works on podcasts, it's too slow. Other than that, it's hard to find fault. I've had no trouble exceeding 36 mpg on every tank full. I've had it for nearly a year now and have had no problems at all. It has plenty of power for me and a comfortable ride. Nothing much compares if you want a hybrid SUV with some size to it. I just had my one-year free oil change and check and I'm still loving it. It's spring and gas mileage is back up around 40 from a low during winter of 37. As a friendly reminder, please avoid listening to the radio (accessory mode) for over two hours waiting on your wife at the doctor to prevent any issues with the battery.I hope you're doing well! I wanted to share my experience with the Highlander. I recently discovered that the 12V battery can deplete quite quickly. Did you know that unless the lead acid battery is above a certain voltage, you aren't permitted to start the car (software)? To avoid this, I now use headphones to listen to podcasts and avoid accessory mode for extended periods. I also carry a small jump-start battery, just in case. I think it's important for owners to be aware of this. Despite this, I still love my Highlander! It's still getting 38-40 mpg and is quiet and smooth. I haven't had any other issues in the 2 1/2 years I've owned it. At my last free maintenance check/oil change, they informed me of tire wear and brake pad wear. It seemed excessive to me, considering I drive very conservatively and use regenerative braking almost exclusively to get max mpg. Nearly all of my miles were local, non-interstate, at or below 55 mph. I drove about 14,000 miles. These findings don't make sense to me. At this rate, I'll need brakes and tires at 45K. I've been told that regenerative braking saves on brake pads and slow, gentle driving saves on tires. Otherwise, though, I still highly recommend the car. Thanks for listening!

I just got this new Highlander Hybrid for one week and it has been so awesome! I traded in my 2014 RAV4 for the 2021 Highlander Hybrid and the experience has been great. The mpg is fantastic, not to mention all the high tech features the vehicle has to offer. It's so smooth on the road that you don't feel a thing. If I could, I would get a second Highlander Hybrid. It's definitely the best SUV hybrid out there in its class!

I'm so glad to hear that you're enjoying your new Highlander! It sounds like it's meeting all of your expectations and more. I'm especially impressed by the great fuel economy you're getting, and it's great to hear that the regenerative braking system is working so well for you. It's always a bit of a shock to buy a new car, but it sounds like this one was definitely worth it. Thanks for sharing your experience with us!

Are you having problems with your 2021 Toyota Highlander hybrid?
Bennie Heidenreich 2025-02-14
undefinedI understand your frustration with the car not having a self-lock feature when you walk away, especially when you have your hands full with a toddler and infant. It can be inconvenient to have to manually lock the car or touch the door handle. However, it's good to know that the app notifies you when the car is unlocked so you can remember to lock it. Overall, I appreciate your honest review of the car. While the fuel economy could be better, the interior is spacious and comfortable, and the car has an attractive design. It's unfortunate that the engine and wind noise detract from the driving experience. I can understand why you wouldn't lease this car again, but I hope that you find a car that better suits your needs in the future. Thank you for sharing your thoughts and experiences with us.

We recently test drove a 2021 Highlander Hybrid and 2021 Sienna Hybrid at the dealership and we absolutely fell in love with the Sienna! While we enjoyed the Highlander, we did notice a couple of issues. Firstly, the third row seat is of much lesser quality than the middle row seats, and secondly, there is very little storage if using the third row seat. On the other hand, the Sienna's third row seat is the same quality as the second row seats, and there is twice as much rear storage than the Highlander. In addition, the Sienna has a much smoother drive and feel than the Highlander.

This car has a range of 300 miles on a full tank, which is lower than advertised.

We have been loyal Toyota customers for 15 years, drawn to their superb quality and low annual maintenance costs. However, we were disappointed to learn that Toyota has recently moved to an annual fee-based system for remote start. We were surprised to find out that remote start was included in our new Highlander Hybrid, but only if we paid an $80.00 annual subscription fee. Interestingly, our 2016 Highlander Hybrid's remote start does not require an annual fee. The only difference is a software change that now requires a yearly subscription. Lia Toyota, our dealer, was willing to work with us as much as they could, but Toyota corporate was not as helpful. The dealership even said that the owner of the dealership called corporate and they were not very accommodating. While it may be cheaper to purchase an outside remote start system than to pay Toyota's annual fee, we are disappointed that Toyota is moving to an annual subscription model to increase their profit margins. We feel that this is unnecessary, especially considering the high cost of their vehicles. Had we known about this change, we may have reconsidered our decision to trade in our debt-free 2016 RAV4 for this new vehicle.

Hey there! I hope you're doing well. I just wanted to share my experience with you. I recently drove down the interstate at 78 mph for half the way and 81 mph for the other half, and I managed to get 22.7 mpg with a full tank! The terrain was mostly flat with a few rolling hills, but nothing too steep. I did notice that when I went over 65 mph, my mpg took a pretty big hit. Just thought I'd share in case it's helpful to you!
