Purchasing a pre-owned compact SUV means balancing styling and capability against mechanical longevity. The 2021 model year of this popular crossover attracts buyers with its rugged styling and comfortable interior, but it also carries a mixed reputation for mechanical and electrical dependability. If you're looking at buying a used unit or trying to diagnose frustrating symptoms on one you already own, understanding the most frequent pain points helps you avoid expensive repair bills.
Real-world owner feedback highlights several recurring trouble spots. From powertrain hesitations to unexpected electrical glitches, knowing what goes wrong gives you the leverage you need during inspections or maintenance visits.
Powertrain and Transmission Performance
The powertrain forms the backbone of any daily driver, yet it represents a primary source of frustration for owners.
Transmission Hesitation and Shuddering
Many drivers report a noticeable lag when pressing the gas pedal, creating hazardous delays when pulling into fast-moving traffic. Automatic transmission configurations often exhibit rough shifts, gear hunting, or a low-speed shudder between 20 and 40 miles per hour.
- Symptoms: Delayed throttle response, harsh downshifts when slowing down, and a vibrating sensation during acceleration.
- Diagnosis: Powertrain Control Module (PCM) software calibration issues frequently cause these behaviors. Dealerships often resolve mild symptoms with a simple software flash, though worn internal components require mechanical overhaul.
Engine Stalling and Misfires
Random engine stalling at low speeds or during idle has surfaced in owner forums. Drivers describe instances where the vehicle shuts down unexpectedly while slowing for a turn or stopping at a traffic light.
- Common triggers: Faulty ignition coils, dirty throttle bodies, and failing crankshaft position sensors.
- Preventative care: Cleaning the throttle body every 30,000 miles and replacing spark plugs on schedule keeps idle stability intact.
Electrical Gremlins and Infotainment Glitches
Modern vehicles rely heavily on complex wiring harnesses and digital modules, and this platform is no exception.
Battery Drain and Charging Failures
Unexplained battery drain leaves some drivers facing a dead vehicle after it sits parked for a day or two. Parasitic draws often stem from the body control module or infotainment system failing to enter "sleep" mode when the ignition shuts off.
Infotainment Freezes
The Uconnect touchscreen occasionally freezes, drops Bluetooth pairing, or causes the backup camera display to flicker or fail entirely. While software updates usually fix these software bugs, persistent hardware failures require complete unit replacements.
Body Integrity and Fluid Leaks
Mechanical wear isn't limited to electronics and gears. Physical components present their own set of maintenance headaches.
Oil Leaks
Owners have documented premature oil leaks around the valve cover gaskets and oil pan seals. Catching these leaks early prevents low oil levels that lead to internal engine damage. Regular undercarriage inspections during oil changes remain vital.
Suspension Noises
Clunking or squeaking noises from the front suspension over speed bumps typically point to worn-out sway bar links, strut mounts, or control arm bushings.
Maintenance Strategy and Inspection Checklist
If you inspect a pre-owned model, use a structured approach to catch these issues before exchanging money.
- Test Drive Thoroughly: Pay close attention to how the vehicle accelerates from a dead stop and shifts through lower gears. Drive up a hill to test for power loss.
- Scan for Pending Codes: Plug an OBD-II scanner into the diagnostic port to check for cleared fault codes or hidden misfire history.
- Verify Recall History: Check the NHTSA Recalls Page using the specific vehicle identification number to ensure all safety campaigns have been completed.
- Inspect the Battery Age: Test the health of the 12-volt battery, as weak batteries trigger erratic electrical warnings across multiple modules.

Frequently Asked Questions
Is the 2021 model year reliable overall?
It earns average reliability marks from industry evaluators like J.D. Power. While many owners experience trouble-free driving, a significant minority face recurring transmission and electrical complaints.
What should I do if my transmission shudders?
Take the vehicle to a certified technician to check for fluid degradation and request a PCM software update. Addressing transmission behavior early prevents catastrophic internal damage.
Are recalls common for this model?
Manufacturers issue safety recalls periodically for various components, including rearview camera software and lighting controllers. Always verify that open campaigns are resolved free of charge by a local dealer.
How can I check for hidden electronic issues?
Turn on every electrical accessory—including the heater, air conditioning, defroster, and windows—simultaneously during a test drive to test the alternator and battery under load.
