Specs side by side
What owners say
X4 M
Overall
Mixed sentiment with a clear distinction between the high-performance M model and the standard X4. The X4 M is described as an "entirely different car" from non-M models, offering a substantial jump in power and performance that owners find compelling. The B58 and previous N55 inline-six turbo engines in the M40i and M models are frequently praised for being "dead reliable" and "a monster of a motor." However, significant and recurrent criticisms focus on punitive maintenance costs as the vehicle ages, poor rear visibility and compromised cargo space due to the coupe design, and persistent issues with tire wear and alignment on vehicles equipped with large wheels and sport suspensions.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. However, there is a strong, recurrent opinion that the full "M" model (e.g., X4 M Competition) is worth the significant price premium over the M Performance model (X4 M40i), described as an "entirely different car" with different interior materials and a substantially more powerful driving experience.
Known issues
- ⚠High maintenance and repair costs: described as "punitive" and becoming very expensive after approximately 60,000 miles, with dealership service charges frequently cited as high. Frequency: very frequent.
- ⚠Excessive and uneven tire wear: particularly on front tires with outer edge wear, noted on vehicles with 20" wheels and sport suspensions, often requiring replacement as early as 15,000 miles. Frequency: recurrent.
- ⚠Alignment difficulties and pulling: issues with pulling to one side, especially in winter conditions, with some reports of non-dealer shops being unable to properly diagnose or correct the alignment. Frequency: recurrent.
GV80
Overall
Mixed sentiment with a clear divide between high praise for the vehicle's design, interior quality, technology, and driving experience, and significant criticism regarding reliability, dealership service, and specific mechanical issues. The vehicle is frequently described as offering exceptional value, with a luxurious interior, strong engine performance (particularly the 3.5T), and advanced tech features that often surpass German competitors at a lower price point. However, this positive ownership experience is frequently undermined by recurrent mechanical problems: most notably rear differential/transfer case failures: and a widely panned dealership and service experience characterized by long wait times for parts, lack of loaner vehicles, and poor communication.
Best version to buy
The 3.5T Prestige trim is most frequently cited as the ideal configuration. Owners highlight the superior power and refinement of the 3.5-liter twin-turbo V6 over the 2.5T four-cylinder, and the Prestige trim's Nappa leather and comprehensive feature set.
Known issues
- ⚠Rear differential/transfer case failure: causes include unspecified malfunction, part failures leading to long backorders (e.g., multiple months). Frequency: very frequent.
- ⚠Dealership/service experience: atrocious customer service, long wait times for appointments, frequent unavailability of loaner vehicles, poor communication, parts delays, issues more pronounced at Hyundai-shared dealerships vs.
- ⚠Poor fuel economy: consistently reported as "shockingly bad," a significant negative noted in comparisons. Frequency: very frequent.
