Chevrolet Malibu
3.5-liter High Value V6 from the 90s, recycled as the 2008 Malibu base V6. OHV architecture, 217 hp, simple design. Only one model year before the 3.6L LY7 replaced it. Mechanically robust but already outdated at launch.
2008 only — the transition V6
The 3.5 LZ4 was the stopgap between the old GM V6 program and the new 3.6 High Feature. Used only in the 2008 Malibu, simple and mechanically robust but without any appeal. Anyone finding a Malibu with this engine has bought a car that belongs nowhere.
Vehicle Weaknesses 5
NHTSA 14V-153: electric power steering can fail suddenly. 438 NHTSA complaints on 2010 MY alone. GM covered 10 years/150,000 mi, out-of-warranty $900–$1,600.
The Passlock security sensor in the ignition switch fails and blocks engine start. Security light on, engine cranks but won't start. Ignition switch replacement fixes it.
The 6T40 six-speed automatic shows shift shock and flare on 2nd and 6th gear from wear and casting debris in the valve body. Valve body rebuild from $400, full rebuild significantly more.
The A/C compressor locks up or makes noise. A standard Malibu theme across all generations. Replacement $800–$1,400.
Sunroof drains clog up, water makes its way into the headliner and trunk. Regular cleaning helps prevent it.
