2022 TOYOTA PROACE CITY PL

Typical onset: 30,000-60,000 mi

Symptoms: Shuddering or hesitation during low-speed shifts (1st to 2nd gear), Clunking noise on acceleration from stop, Excessive vibration at idle in Drive, Transmission mount tears visible on inspection

Fix: Transmission mounts fail early due to torque converter shudder inherent to the EAT8. Replacing mounts is 2-3 hours labor but often recurs unless transmission software is updated and fluid changed. Some cases require torque converter replacement at 4-6 hours labor. Always do fluid service simultaneously.

Estimated cost: $600-2,800

Typical onset: 40,000-80,000 mi

Symptoms: Check engine light with P2463 (DPF efficiency below threshold), Repeated regen attempts, poor fuel economy, Loss of power, limp mode activation, Black smoke on hard acceleration

Fix: Short trip usage kills the DPF system on these diesels. EGR valve clogs simultaneously. Proper fix requires DPF removal and professional cleaning ($400-600), EGR replacement or cleaning (3 hours labor), and software adaptation. DPF replacement is $2,000+ for the part alone. Prevention requires monthly highway runs of 30+ minutes.

Estimated cost: $1,200-3,500

Typical onset: 60,000-100,000 mi

Symptoms: Metallic rattling from engine on cold start, Oil consumption increasing (1 qt per 1,000 mi), Check engine light with timing correlation codes, Metal particles visible in oil

Fix: The wet-belt-in-oil design on PureTech engines deteriorates, shedding material into the oil system. Once rattling starts, engine damage is often already occurring. Requires complete timing system replacement (belt, tensioners, guides) at 8-10 hours labor, oil system flush, and often turbocharger due to debris. This is a known class-action-level defect on PSA engines. Preventive replacement at 60k miles recommended.

Estimated cost: $2,500-5,000

Typical onset: 50,000-90,000 mi

Symptoms: Humming or grinding noise from front wheels that increases with speed, Vibration through steering wheel at highway speeds, Uneven tire wear on inner or outer edges, ABS/traction control warning lights in severe cases

Fix: Hub bearings integrated into the knuckle assembly fail prematurely, possibly due to inadequate sealing or lightweight design for cargo loads. The entire knuckle assembly must be replaced (bearing not serviceable separately) at 2.5-3 hours per side. Alignment required after. Often both sides need attention within 10k miles of each other.

Estimated cost: $800-1,400

Typical onset: 40,000-70,000 mi

Symptoms: Red fluid spots under vehicle after parking, Low transmission fluid warning light, Harsh shifting or slipping when fluid level drops, Visible corrosion on steel cooler lines near subframe

Fix: Steel transmission cooler lines rust through at mounting points and bends, especially in salt-belt states. Requires line replacement (dealer-only parts often) at 2-3 hours labor, plus fluid refill and system purge. Aftermarket braided stainless lines available but require custom fitting. Check annually if in rust-prone areas.

Estimated cost: $500-1,100

Symptoms: Sweet coolant smell inside cabin when heater runs, Wet passenger-side floor carpet, Windshield fogging that won't clear, Coolant level dropping with no external leaks visible

Fix: Heater cores develop pinhole leaks due to electrolysis or manufacturing defects. Dashboard removal required for access, making this a 6-8 hour job. Flush entire cooling system during repair to prevent repeat failure. Some techs report improved longevity with OEM Toyota coolant vs. PSA-spec fluid.

Estimated cost: $1,200-2,000
