PROBLEM DETAILS

Brake actuator assembly failure

Hard pedal resistance, unpredictable braking, ABS warning lights and spongy pedal feel

Check engine light: On

Brake actuator assembly failures cause hard pedal resistance and unpredictable braking, with ABS malfunctions showing up as warning lights or a spongy brake feel. Multiple complainants reference an extended warranty program covering this defect rather than a formal recall — an 'acknowledged defect, no recall' situation, where the manufacturer addresses a known, safety-relevant defect through a warranty mechanism rather than a recall, leaving owners outside the program's window to pay out of pocket.

Sunroof glass spontaneous shattering

Glass shatters while driving, described as happening for no apparent reason

Check engine light: Off

Spontaneous sunroof glass shattering while driving. The same defect is reported on the Nissan Murano, Toyota Venza, Mitsubishi Outlander and Honda Pilot.

Oil cooler hose rupture

Complete oil loss, potential engine seizure or destruction

Check engine light: On

Rubber oil cooler hoses are prone to failure and rupture, leading to complete oil loss and, in the worst cases, engine seizure or destruction. Separately, water pump failures cause overheating, and VVT (variable valve timing) gear rattling is reported at cold startup.

↑ Back to the problem table

Dashboard cracking, melting, and crumbling

Cracking, melting, odors, and glare from a shiny or sticky dashboard surface

Check engine light: Off

Dashboards crack, melt, and crumble, emitting odors, with some owners raising concerns about a compromised dashboard interfering with airbag deployment, and separately about glare or reduced visibility from the resulting sticky or shiny surface. This was addressed via a limited warranty program that has since expired, as with the brake actuator problem above.

Power steering rack leak

Fluid seepage from dust boots, sometimes requiring full rack replacement

Check engine light: Off

Fluid seepage from the power steering rack's dust boots, sometimes requiring complete rack replacement.
