2025 CHEVROLET CAVALIER

Typical onset: 80,000-130,000 mi

Symptoms: Cold-start rattle lasting 3-5 seconds that progressively worsens, Check engine light with P0017 (cam/crank correlation) codes, Rough idle and hesitation on acceleration, Metallic grinding noise from front of engine

Fix: Replace timing chain, tensioner, guides, and usually both VVT solenoids while you're in there. 8-10 hours labor because of tight engine bay and need to drop the subframe for proper access. Do NOT ignore this — jumped timing destroys valves and pistons.

Estimated cost: $1,800-2,800

Typical onset: 60,000-100,000 mi

Symptoms: Ticking or tapping noise that increases with RPM, worst when hot, Misfire codes on specific cylinders (P0300-P0304), Loss of power and fuel economy drop, Metal shavings in oil during changes

Fix: Failed lifters require head removal to replace all lifters properly, plus you're cleaning oil passages and inspecting cam lobes. If caught early, sometimes single lifter replacement works (4 hours), but most techs do all of them to prevent comebacks. 12-16 hours for full job with head R&R. Camshaft replacement adds another $400-600 if lobes are scored.

Estimated cost: $2,200-4,500

Typical onset: 50,000-80,000 mi

Symptoms: Shuddering or vibration during light acceleration (30-45 mph), Delayed engagement when shifting from Park to Drive, Whining or humming noise that changes with speed, Transmission temperature warning light on hard pulls or towing

Fix: CVT fluid should be changed every 30-40k despite GM saying 'lifetime.' Drain-and-fill helps early shudder (2 hours). Advanced cases need full flush with external cooler cleaning, sometimes transmission mount replacement because they fail and cause sympathetic vibrations. If the belt or pulleys are scored, you're looking at $4k+ for CVT replacement.

Estimated cost: $300-800

Typical onset: 70,000-110,000 mi

Symptoms: Transmission fluid spots under vehicle (red or brown), Low transmission fluid warnings on dash, Burnt smell from engine bay, Fluid visible on cooler lines near radiator

Fix: Cooler lines corrode where they connect to the radiator or at crimp points. Lines themselves are cheap, but access requires removing wheel well liner and sometimes the bumper cover. 2-3 hours labor. Always inspect the cooler itself for internal leaks into the coolant — if you see milkshake fluid, cooler needs replacement too.

Estimated cost: $400-900

Typical onset: 90,000-140,000 mi

Symptoms: Visible wobble of the crankshaft pulley when engine is running, Squealing serpentine belt that keeps coming off, Rough vibration at idle that smooths out at higher RPM, Separation of rubber ring from outer pulley (visible inspection)

Fix: The rubber damper deteriorates and the outer ring separates, which throws off belt alignment and can destroy the crankshaft snout if the balancer walks off. Replacement requires special puller and installer tools — don't attempt with a regular puller or you'll crack it. 2-3 hours labor, but critical because failure can strand you instantly.

Estimated cost: $500-850

Typical onset: 60,000-90,000 mi

Symptoms: Hard starting, especially after sitting overnight, Stumbling or surging during acceleration, Loss of power on highway on-ramps, Fuel pump whine that's louder than normal

Fix: The in-tank strainer clogs with sediment, starving the high-pressure pump. Requires dropping the fuel tank (3-4 hours), and while you're in there, replace the fuel pump assembly if it's showing 80k+ miles — they fail shortly after. The filter itself is $40 but labor makes this expensive.

Estimated cost: $600-1,100
