2021 Kia Sorento problems

The Kia Sorento (Korean: 기아 쏘렌토, romanized: Gia Sorento) is a series of automobiles manufactured by the South Korean manufacturer Kia since 2002 through four generations. Initially a compact SUV built on a body-on-frame chassis, the second-generation Sorento transitioned to a larger car-based platform which placed it into the mid-size crossover SUV class, and has been developed alongside the Hyundai Santa Fe.
First generation (BL; 2002)
2002–2006
Debuting in February 2002, the first generation Sorento was a traditional truck-based body-on-frame SUV. All American Sorentos also came with dual front airbags and dual side-curtain airbags in the front and rear. An optional four-wheel drive system with low range received praise for adding to the vehicle's off-road ability.
It had two transmission options, a 5-speed manual or 4- and 5-speed automatic (pre-2005 models have a 4-speed automatic, whilst 2005 Sorentos came with a 5-speed tip-tronic style automatic). First generation Sorentos are equipped with a Hyundai-manufactured 3.5-liter 24-valve DOHC V6 engine producing 192 hp (143 kW) at 5500 rpm, and 217 lb⋅ft (294 N⋅m) of torque at 3,000 rpm. Common features of the first generation Sorento were 4-wheel disc brakes (standard on all models), optional anti-lock braking system (ABS), and a 21.1-gallon (79.9 litres) fuel tank.
There were two trim levels available for the Sorento: either the base LX or the up-level EX. Both models included an AM/FM stereo with a single-disc CD player and an eight-speaker audio system, dual front airbags and front and rear side-impact SRS airbags (side-impact front and rear SRS airbags for North American-market models ONLY), cloth seating surfaces, a power-adjustable front driver's seat, air conditioning, power door locks and windows, tinted windows, aluminum-alloy wheels, keyless entry, wood interior trim accents, a split-folding second-row rear bench seat, and monotone exterior paint as standard equipment. Features such as satellite radio (on later models), leather-trimmed seating surfaces, heated front seats, a ten-speaker premium audio system, cassette and CD players, an in-dash CD changer, power front bucket seats, seventeen-inch (17") aluminum-alloy wheels, a power sunroof, two-tone exterior paint, and a security system were available regardless of trim level choice.

Great handling, although a bit noisy due to the cross contact lx continental tires. The car hesitates a bit in eco mode, but not in sport. Sometimes the auto shutoff feature causes sluggish takeoff. It's disappointing that the tires wore out after only 47,000 km. The seats are not the most comfortable for long trips, and general maintenance items are very expensive, such as a $2700 windshield, $2500 per headlamp, and brakes costing approximately $1600. All of these expenses are required within the first 100,000 km.

I recently purchased the 2021 Kia Sorento SX Prestige X-Line on Christmas Eve and I must say, the ride is incredibly smooth and the horsepower is excellent! Although, I can't help but feel that I downgraded in some ways compared to my previous vehicle, a 2016 Kia Sorento SXL 2.0 Turbo. However, I still enjoy my 2021 Sorento and it's great. I just miss some of the features that my 16' Sorento had, such as driver memory seats, heated rear seats, and rear window shades. I like my passengers to be comfortable as well, but I understand that not all features can be included in every model. Despite this, my SX Prestige still has a lot of technological features that were absent on my older Sorento, and the panoramic sunroof is a great addition. Overall, I'm really happy with my purchase and my SX Prestige is truly spoiling me!

Congratulations on your new 2021 SX AWD! It sounds like you made a great choice. The car's advanced technology is impressive, especially the gorgeous and crisp infotainment screen. It's great to hear that your pre-teen/teenagers can all fit comfortably in the car, even though the third row isn't as big as the Telluride. The smooth driving experience is also a plus, making it feel like a nice sedan rather than a bulky SUV. The second row button to move seats forward is a clever feature that allows for quick and easy access to the back. The storage under the lift in the 'trunk' area is also a useful addition. Thank you for sharing your positive experience with us, it's always great to hear from satisfied customers!

You've owned this car for about 3 months now and it's been a great experience so far. The interior is absolutely beautiful and the turbo provides plenty of power. It drives like a dream and the captain chairs and wood grain interior were the main reasons for your purchase. Although it doesn't have a homelink rear mirror, seat selector, or display on the windshield, it's still a very stylish car that gets compliments all the time. The 3rd row is a nice feature to have, even though it's more suitable for small kids. Overall, it's been a great purchase and you're very happy with it.

Everything you need and nothing more. We could have gone for a larger SUV but this fits. The space is useful, not excessive. The drive is smooth too. :)*. Update: still love it. Update 2 …. 35000km no issues still love it ** Second update: still a great vehicle - although the seats could be more comfortable

Although I experienced some issues with my brand new Sorento X-Line Prestige, I am confident in my assessment that the reliability of the DCT transmission in Kias and Hyundais is not up to par. It is important to note that this model is built in the USA and may not have the same level of quality as those built in Korea. However, I have had positive experiences with other Kias in the past, including Stingers. I would recommend considering a Telluride or a Sportage if you are in the market for an SUV. Thank you for your attention.

I purchased the 2021 Sorento Hybrid after careful consideration. While the front seats are not as comfortable as our previous 2012 T&C, the ride and handling are still impressive. Although I was disappointed to find out that there was no spare tire and the mileage was not as good as I expected from a hybrid. Additionally, the sound system did not meet my expectations. However, I am confident in my decision and believe that I will continue to enjoy driving this car. Thank you for the opportunity to share my thoughts.

I strongly advise against purchasing the new Sorento SX XLine. Despite being able to drive it for a day, on the second day, all the safety equipment, including the Blind Spot, stopped working. The dashboard is lit up with warning lights, including the ABS light. When applying the brakes to stop, they vibrate excessively and produce a loud noise, which is concerning.

This car has been a disappointment since the first month of ownership in April 2021, when it stalled and turned off while on the highway. Despite taking it in for diagnostic tests, no issues were found. After driving it for 10,000 miles, the transmission started to make clunky noises and kick. Once again, KIA found no issues in the diagnostic tests and the mechanic did not feel any issues while driving it. While the sunroof is a nice feature, it can be moody when it comes to closing. Unfortunately, this car lacks reliability, comfort, and space. I would recommend choosing another car. In fact, I am already trading mine in after only owning it for 16 months.

I purchased a Kia Sorento Turbo, top of the line, but unfortunately experienced transmission issues within a year of ownership. The vehicle has been in the dealership shop for over a month, with no estimated time of repair. This has been a disappointing experience, as it has impacted our quality of life. I believe that there is room for improvement in the customer service provided to expedite the resolution of this issue.
