The fifth-gen CR-V is a top compact SUV, but the 1.5T engine's oil-dilution issue is the key thing to verify before buying.
Compiled & reviewed by the VehicleFaults Research Team · last reviewed July 2026
The most commonly reported faults on the 2017–2022 Honda CR-V are 1.5T oil dilution — fuel enters the oil, worse in cold climates/short trips, Engine misfires, illuminated EML, and a strong smell of unburnt fuel from the exhaust due to premature fuel injector failure on 1.5 VTEC Turbo models and AC condenser failure / refrigerant leaks. 2 of the documented issues are rated high severity · inspect these first. Full inspection points, onset mileage and what to check are listed below.

Vibration at idle on 1.5T from oil dilution.
Engine misfires, illuminated EML, and a strong smell of unburnt fuel from the exhaust due to premature fuel injector failure on 1.5 VTEC Turbo models.
A loud, metallic grinding or rattling noise lasting one to two seconds immediately upon a cold start, caused by a faulty Variable Timing Control (VTC) actuator.
A groaning, rubbing, or juddering noise from the rear axle during tight, low-speed turns, indicating degraded Dual Pump Fluid in AWD models.
Power tailgate fails to open fully, sags, or reverses direction unexpectedly due to failing motorised struts or a faulty control module.

Build my inspection planThe 1.5T is prone to fuel diluting the oil; software updates and highway use help — always inspect the oil.
The naturally aspirated 2.4L (2017 base/earlier) avoids the oil-dilution issue and is very reliable.
Yes — it's one of the most dependable compact SUVs, with the 1.5T oil concern the main caveat.
Yes. The all-wheel-drive system relies on Honda's Dual Pump Fluid II in the rear differential. This fluid degrades faster than standard gear oils and requires changing every 30,000 to 40,000 miles. Neglecting this leads to differential groaning during tight turns and can cause premature wear to the clutch packs.
The 2.0 i-MMD hybrid system is generally robust, but dealers should check the transition between EV and combustion modes. It should be seamless. Listen for excessive engine revving under moderate acceleration, which can indicate a depleted high-voltage battery or software issues. Ensure the battery cooling fan isn't blocked.
The Continuously Variable Transmission is mechanically sound provided it receives regular fluid changes every 25,000 to 30,000 miles using genuine Honda HCF-2 fluid. During a test drive, watch for juddering from a standstill or surging RPMs at a constant speed, which indicates degraded fluid or a stretched pushbelt.
