Owner complaint databases give a rough picture of which vehicles left the most people frustrated. This list pulls SUVs and crossovers from Nissan, Mazda, GM, Mitsubishi, Lincoln, Hyundai and Volvo, using the counts posted on CarComplaints brand pages. Twelve models follow, ranging from four-digit totals to a few dozen reports.

1. Nissan Xterra: Xterra Tops The Count

Nissan’s Xterra leads this list by volume. The brand page on the Xterra page on CarComplaints shows 1,079 complaints filed by owners, the highest figure among the twelve models here and a clear gap above the next entry, which is another Nissan.
A raw tally is not a failure rate. Sales volume and the number of model years on the road both push counts up, so the figure shows how much owner attention the truck drew, not how often any single Xterra breaks.
2. Nissan Murano: Murano Follows Closely

Another Nissan sits second. Murano owners filed 929 complaints, according to the the Nissan listing, which puts two models from the same brand far ahead of every other vehicle in this gallery and well above the third-place total.
Self-reported counts depend on who chooses to post. The number says many owners had something to report, but it does not rank severity, repair cost or safety risk, and the page total alone cannot show which problems dominate.
3. Mazda Tribute: A Mid-Sized Tribute Tally

Mazda’s Tribute draws 215 complaints in the figures on Mazda’s complaint totals. That is far below the Nissan pair and sits in the middle of the pack, close to the Pontiac Aztek and above the CX-7 from the same brand.
The count alone does not say which problems dominate. Anyone weighing a used Tribute would need to open the individual complaint categories on the page for detail, since one total can hide very different issues.
4. Mazda CX-7: CX-7 Counts 165

The CX-7, Mazda’s other entry, shows 165 complaints on the the Mazda page. That is fewer than the Tribute’s 215, so the brand contributes one mid-range total and one lower one to the list.
Lower totals can reflect fewer vehicles sold rather than fewer problems. The tally is a starting point for research, and it says nothing about repair costs or how any of the complaints were eventually resolved. Readers comparing the two Mazdas should treat the gap as modest.
5. Buick Rendezvous: Rendezvous Logs 373

Buick’s Rendezvous appears with 373 complaints on Buick’s brand listing, the fourth-highest total in the set and just behind the GMC Envoy, which is also a General Motors model in this gallery.
The count covers the whole listing rather than one defect. Owners or shoppers would still have to check which specific complaints cluster within the entry before drawing conclusions about the crossover as a whole. The total alone is only a headline number.
6. GMC Envoy: Envoy Draws 402

GMC’s Envoy edges past the Buick Rendezvous with 402 complaints, per the figures on GMC’s owner reports. Only the two Nissans record more reports among these twelve, which makes the Envoy the top General Motors entry here.
The source presents numbers, not diagnoses. A higher total than the Rendezvous does not by itself show that the Envoy is the less reliable of the two, because sales and age can differ between models.
7. Pontiac Aztek: Aztek Reaches 208

Owners filed 208 complaints on the Pontiac Aztek, according to Pontiac’s complaint page. The number is modest next to the Nissan and General Motors leaders and lands within a handful of reports of the Mazda Tribute.
A count of 208 is the only claim the source supports here. The page does not explain what drove the reports, so the figure should be read as a size of the complaint pile, not a verdict on the vehicle.
8. Pontiac Torrent: Torrent Adds 197

Pontiac’s Torrent sits just below the Aztek, with 197 complaints shown on the the Pontiac listing. Together the two Pontiac models account for 405 entries, which would rank above the Rendezvous if combined.
The gap between the pair is small, and totals shift as owners add reports over time. The figure is a snapshot of the page as read for this list, not a settled ranking of the two models.
9. Mitsubishi Endeavor: Endeavor Stays Small

Mitsubishi’s Endeavor records only 53 complaints on Mitsubishi’s brand page, the smallest number among the twelve vehicles in this gallery and roughly a twentieth of the Xterra’s total.
A low count may mostly reflect limited sales. The page cannot say how many Endeavors are still driven, so the figure should not be read as proof of trouble-free ownership, only as a smaller pile of reports on a model that may not have sold in large numbers.
10. Lincoln Aviator: Aviator Cracks Cost $1,500

Lincoln’s Aviator has 150 complaints on its brand page. One entry on Lincoln’s Aviator entry describes a crack in the rear panel below the window on a 2003 model, averaging $1,500 in repair cost at 89,000 miles.
That cost applies to a single listed complaint on one model year. It should not be extended to every Aviator or to the other problems owners have reported, which the summary figures here do not itemize.
11. Hyundai Veracruz: Veracruz Totals 75

Hyundai’s Veracruz shows 75 complaints on Hyundai’s page. It is one of the lower totals here, second only to the Mitsubishi Endeavor, and the only Hyundai in the set, so the brand page offers a single point of comparison.
Small numbers cut both ways. They may indicate fewer problems or simply fewer vehicles on the road, and the page alone cannot separate those explanations, so the count is best treated as context rather than a conclusion, much like the other low totals here.
12. Volvo XC90: XC90 Loses Power

Volvo’s XC90 has 129 complaints, the most for the brand on Volvo’s most-reported model. One listed problem, a 2016 XC90 losing all power while driving, averages $20,000 in repair cost at 62,000 miles.
That figure comes from one listed problem on one model year. It illustrates a high-cost case, not the typical outcome for XC90 owners, and the summary used here does not give a cause for the power loss.
