2001 HONDA CR-V

Typical onset: 120,000-180,000 mi

Symptoms: Delayed engagement when shifting into drive or reverse after warm-up, Slipping between 2nd and 3rd gear under moderate throttle, Transmission fluid turns dark brown or smells burnt well before service interval, Complete loss of forward gears, usually stranding the vehicle

Fix: The factory transmission cooler is marginal at best. Failures often damage the torque converter and clutch packs beyond rebuild viability. Most shops recommend remanufactured unit replacement plus external auxiliary cooler installation to prevent repeat failure. Figure 12-16 hours labor for R&R plus cooler install.

Estimated cost: $2,800-4,200

Typical onset: 150,000-220,000 mi

Symptoms: Blue smoke on cold start that clears after 30 seconds, Consuming 1 quart of oil every 800-1,200 miles, Oil fouling on spark plugs, causing misfires on cylinders 2 and 3 typically, Eventually progresses to low compression and hard starting

Fix: Piston ring end-gap wear is endemic to high-mileage B20 engines. Minor cases can limp along with frequent oil top-offs, but once compression drops or oil consumption exceeds 1 qt per 500 mi, you're looking at either a full engine rebuild (machine work, all new rings, bearings, seals) at 24-30 hours, or a low-mileage JDM B20B swap at 14-18 hours. Rebuilds rarely pencil out economically.

Estimated cost: $3,200-5,500

Typical onset: 100,000-160,000 mi

Symptoms: Howling or whining noise from rear that increases with vehicle speed, Oil spots under rear center of vehicle after overnight parking, Vibration through floor during highway cruising

Fix: The rear diff pinion seal fails, letting fluid leak and causing accelerated bearing wear. If caught early with just the seal, it's 2-3 hours. If bearings are damaged, you're rebuilding the diff or replacing it with a used unit, 5-7 hours total including setup and fluid.

Estimated cost: $400-1,200

Typical onset: 90,000-140,000 mi

Symptoms: Clunking over bumps from front suspension, Steering wander or vehicle pulling to one side, Visible play when prying on lower control arm with tire off ground, In extreme cases, complete separation causing loss of steering control

Fix: Ball joints are pressed into the lower control arms and wear out the bores. Most shops replace the entire control arm assembly rather than pressing new joints. Both sides should be done simultaneously even if only one is bad. 3-4 hours for both sides plus alignment.

Estimated cost: $600-950

Typical onset: 120,000-200,000 mi

Symptoms: Ticking or tapping noise from engine bay on cold start, quiets as engine warms, Exhaust smell in cabin with fresh air vents on, Check engine light with P0420 catalyst efficiency code, Visible cracks on manifold between cylinders 2-3

Fix: The exhaust manifold develops stress cracks from heat cycling. You can band-aid it with high-temp epoxy for a few months, but proper fix is manifold replacement. Studs usually break during removal. 4-5 hours to replace manifold and front pipe, includes dealing with seized hardware.

Estimated cost: $650-1,100

Symptoms: Key turns but dash lights don't come on, or come on intermittently, No crank, no start, but battery is good, Wiggling key in ignition sometimes gets it to start, Complete electrical dead after key is turned

Fix: The electrical portion of the ignition switch (separate from the lock cylinder) has internal contact failure. It's behind the steering column cover. Replacement takes about 1.5 hours and requires pulling the column shroud and disconnecting the airbag.

Estimated cost: $280-450
