A new SUV can feel like a smart investment until the warranty expires and the repair bills start stacking up. For 2026, three independent data sources point to the same uncomfortable conclusion: at least nine popular SUVs are generating far more shop visits, owner complaints, and costly breakdowns than the rest of the market. Below is the list, along with the evidence behind each entry and what mechanics say is actually going wrong under the hood.
Where this list comes from
The models below were flagged by overlapping findings from J.D. Power’s 2026 U.S. Vehicle Dependability Study, which measures problems per 100 vehicles (PP100) at the three-year ownership mark; Consumer Reports’ Annual Auto Surveys, drawing on roughly 380,000 owner responses to generate predicted reliability scores; and the National Highway Traffic Safety Administration’s consumer-complaint database, where patterns of engine failures, transmission breakdowns, and electrical malfunctions are publicly documented. A dedicated Consumer Reports video segment on the least reliable SUVs of 2026 distills the survey data into a focused warning list for sport-utility shoppers.
When a model shows up in two or all three of these sources, the “money pit” label carries real statistical weight. Here are the nine that earned it as of June 2026.
1. Chevrolet Blazer EV
GM’s electric Blazer launched with ambitious tech but rocky execution. Consumer Reports gave it a well-below-average predicted reliability score, citing repeated owner reports of software glitches, charging-system errors, and infotainment screens that freeze or reboot mid-drive. NHTSA complaint records show clusters of reports involving sudden loss of propulsion and high-voltage battery warnings. Mechanics working on early examples report that many issues require dealer-only diagnostic tools and lengthy waits for replacement control modules, driving up both downtime and cost.
2. Mercedes-Benz GLE
The GLE has appeared on below-average reliability lists from Consumer Reports for multiple model years running. J.D. Power’s dependability data places Mercedes-Benz well below the industry average in PP100 scores, and the GLE is a primary contributor. Common trouble spots include the 48-volt mild-hybrid system, the MBUX infotainment platform, and air-suspension components that can cost north of $2,000 per corner to replace. NHTSA records include complaints about engine stalling and transmission hesitation in both the GLE 350 and GLE 450 variants.
3. Jeep Grand Cherokee
Stellantis brands have struggled in recent dependability rankings, and the Grand Cherokee is a repeat offender. The current-generation model, built on the STLA Large platform, has drawn J.D. Power scores that trail the midsize SUV segment average by a wide margin. Consumer Reports flags the eight-speed automatic transmission, the Uconnect 5 infotainment system, and electrical gremlins as persistent weak points. Mechanics report that wiring-harness issues and sensor failures can trigger cascading warning lights that are time-consuming and expensive to diagnose.
4. Volkswagen ID.4
Volkswagen’s mainstream electric SUV has been dogged by software problems since its U.S. launch. Consumer Reports rates its predicted reliability well below average, with owners reporting unresponsive touchscreens, phantom driver-assistance alerts, and 12-volt battery drain that can leave the vehicle unable to start. NHTSA complaints include sudden power reductions at highway speed. Independent shops note that many ID.4 repairs require VW-proprietary software updates that only franchised dealers can perform, limiting options and inflating labor bills.
5. BMW X5
BMW consistently lands below the industry average in J.D. Power’s dependability study, and the X5 is one of the brand’s highest-volume models. Consumer Reports has flagged the X5’s inline-six and V8 powertrains for oil-consumption issues, and owners report problems with the iDrive infotainment system and adaptive suspension. Repair costs are steep: a turbocharger replacement on the B58 engine can run $3,000 to $5,000 at an independent shop, and dealer rates push that figure higher. NHTSA records include complaints about coolant leaks and sudden engine shutdowns.
6. Jeep Wrangler 4xe
The plug-in hybrid Wrangler adds a layer of complexity to a platform that already generates above-average complaint volumes. Consumer Reports gives the 4xe a poor predicted reliability score, with the hybrid battery pack, high-voltage wiring, and turbocharged 2.0-liter four-cylinder all drawing owner complaints. NHTSA data includes reports of the gasoline engine failing to start after the electric range is depleted, leaving drivers stranded. Mechanics say the combination of off-road exposure and hybrid-system sensitivity creates failure modes that neither a traditional Wrangler nor a conventional hybrid would produce on its own.
7. Infiniti QX60
Nissan’s luxury division has posted some of the weakest J.D. Power dependability scores among premium brands, and the QX60 is a significant contributor. Consumer Reports flags the continuously variable transmission (CVT) and the ZF nine-speed automatic (depending on model year) as trouble areas, along with persistent complaints about the ProPILOT Assist driver-aid suite producing false alerts. NHTSA records show a pattern of transmission-shudder and hesitation complaints. Independent mechanics note that CVT rebuilds on Nissan-platform vehicles can cost $4,000 or more, a bill that often exceeds the vehicle’s residual value on older examples.
8. Rivian R1S
Rivian’s large electric SUV earns praise for performance and interior design, but its reliability record has not kept pace. Consumer Reports rates the R1S well below average, with owners reporting drive-unit noises, suspension-component failures, and persistent software bugs that affect climate control and vehicle access. Because Rivian’s service network is still limited compared with legacy automakers, wait times for parts and appointments can stretch into weeks. NHTSA complaints include reports of sudden traction-control malfunctions and charging failures. Mechanics outside the Rivian network say they often lack the diagnostic access needed to perform even basic repairs.
9. Land Rover Defender
Land Rover has finished at or near the bottom of J.D. Power’s dependability rankings for years, and the Defender, despite its rugged image, is no exception. Consumer Reports gives it a poor predicted reliability score, with air-suspension failures, electrical faults, and infotainment lockups topping the complaint list. NHTSA records include reports of engine stalling and brake-system warnings. Independent mechanics familiar with the platform say that even routine repairs require specialized tooling, and parts availability for the Defender’s Ingenium engines and Pivi Pro electronics can be unpredictable, adding delay costs on top of already-premium labor rates.
Important caveats for shoppers
A few things to keep in mind before treating this list as gospel. The J.D. Power 2026 dependability study evaluates vehicles at the three-year mark, meaning it primarily reflects 2023 model-year builds rather than brand-new 2026 production. Consumer Reports blends historical data with predictive modeling, which helps forecast problems but cannot fully account for mid-cycle engineering fixes or new powertrains. And NHTSA complaint counts are raw totals: a high-volume seller like the Grand Cherokee will naturally attract more reports than a niche model even if its per-vehicle failure rate is comparable.
That said, when all three sources converge on the same models, the signal is hard to dismiss. Mechanics who work on these vehicles daily reinforce the pattern: the SUVs generating the most owner complaints are the same ones filling up shop bays with repeat visits.
How to protect yourself before buying
Start with safety. Search the exact make, model, and model year in NHTSA’s recall and complaint database. Look for clusters of similar reports, especially stalling, brake failure, or sudden electrical shutdowns, rather than isolated incidents. Next, check brand-level dependability scores from J.D. Power to understand the manufacturer’s overall track record. Finally, consult Consumer Reports’ model-specific reliability predictions for a granular look at which components tend to fail and when.
If the SUV you want appears on multiple warning lists, negotiate accordingly. Push for an extended powertrain warranty, a prepaid maintenance plan, or a price reduction that accounts for the higher expected cost of ownership. And if you are shopping used, get a pre-purchase inspection from an independent mechanic who specializes in that brand. A $200 inspection is cheap insurance against a $5,000 surprise six months down the road.
