The 2022 Chevrolet Tracker MX (rebadged Baojun/Wuling platform sold in Mexico and Latin America) uses small-displacement turbo three-cylinders that suffer from timing chain stretch, lifter failure, and cooling system issues when maintenance lapses. The six-speed automatic transmission is temperamental with fluid quality and mounts wear prematurely.
Timing Chain Stretch and Tensioner Failure
Common · high severityTypical onset: 60,000-90,000 mi
Symptoms: Cold-start rattle lasting 3-5 seconds, sometimes sounds like marbles in a can, Check engine light with cam/crank correlation codes (P0016, P0017), Loss of power or rough idle as timing drifts, Metallic ticking that worsens with low oil or delayed changes
Fix: Timing chain, guides, tensioner, and usually the variable valve timing solenoids. Front cover comes off, often discover worn cam phasers too. 8-10 hours labor depending on which engine and shop familiarity. Use OE or equivalent parts—aftermarket chains have high failure rates on these.
Estimated cost: $1,800-3,200
Hydraulic Lifter Collapse and Camshaft Lobe Wear
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: Persistent valve train ticking that doesn't go away after warm-up, Misfires on one or more cylinders, often P0300-P0303 codes, Low oil pressure warning at idle (when wear is severe), Metal shavings in oil during changes—dead giveaway
Fix: Head has to come off to replace lifters. Often find camshaft lobes worn flat, requiring cam replacement. If cam journals are scored, head needs resurfacing or replacement. Budget 12-15 hours for all lifters plus cam, more if head work needed. Root cause is almost always extended oil change intervals or low-quality oil—these engines need 5W-30 dexos1 Gen 2 every 5,000 mi max.
Estimated cost: $2,500-5,000
Transmission Oil Cooler Line Leaks and Cooler Failure
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Red fluid puddles under engine bay, usually passenger side, Transmission overheat warning on dash, especially during city driving or towing, Harsh or delayed shifts when transmission runs hot, Cross-contamination—coolant in trans fluid or vice versa if internal cooler fails
Fix: External cooler lines corrode at fittings—3 hours to replace lines and top off fluid. If the cooler itself fails (integrated into radiator), you're looking at radiator replacement plus full trans fluid flush to clear contamination. 5-6 hours total. The cooler design is undersized for this transmission's heat load.
Estimated cost: $600-1,800
Transmission Motor Mounts Collapse
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Vibration through cabin at idle, worse with A/C on, Visible engine movement when revving in Park, Driveline shudder during acceleration from stop
Fix: Upper transmission mount is the usual culprit, sometimes the torque strut as well. Hydraulic-style mounts fail internally—rubber separates from metal. 2-3 hours to replace both upper and lower, requires supporting the powertrain. OE mounts last longer than aftermarket—poly mounts create too much NVH on this platform.
Estimated cost: $400-800
Harmonic Balancer Separation and Crankshaft Seal Leaks
Occasional · high severityTypical onset: 80,000-120,000 mi
Symptoms: Squealing belt noise that comes and goes, worse when cold, Visible wobble in balancer pulley—easy to spot with engine running, Oil leak from front crankshaft seal, sometimes misdiagnosed as timing cover leak, Rough idle or vibration if rubber damper ring has separated
Fix: Balancer replacement requires special puller and installer—don't hammer it on. Front seal while you're in there. 3-4 hours labor. If balancer comes apart while driving, it can damage the crank snout—seen it twice. Inspect carefully during timing chain jobs.
Estimated cost: $500-900
Fuel Filter Clogging (Flex-Fuel Models)
Occasional · medium severitySymptoms: Hard starting after sitting overnight, cranks 5-8 seconds before firing, Loss of power above half throttle, feels like fuel starvation, Check engine light with lean codes (P0171, P0174) or low fuel pressure codes, Rough idle and hesitation, especially in hot weather
Fix: In-tank fuel pump module includes filter on these. Drop the tank, replace entire assembly—2.5 hours. Flex-fuel variants (E85 compatible) see premature filter clogging from ethanol's solvent properties loosening tank sediment. Not a scheduled maintenance item in manual but should be done every 60k if running E85 regularly.
Estimated cost: $400-700
Buy only with full service records showing religious oil changes and timing chain replacement or low mileage under 50k; the three-cylinder turbo architecture is maintenance-sensitive and expensive to revive once neglected.
