Chrysler
Some 2003 Jeep Liberty models built prior to April 15, 2003, may produce a moaning sound from the rear-end of the vehicle during light brake pedal application.
According to Chrysler Group L.L.C., the noise usually occurs during the first few stops in the morning when outside temperatures are below 50 F, and is most likely due to moisture infiltrating the linings of the rear brake pads. Installing new-design rear pads, part #05083882AE, should help eliminate the noise.
GM
Owners of 2000-03 Saturn L-series cars built before VIN breakpoint 3Y564034 may complain of insufficient fluid output from the windshield washer nozzles.
General Motors Co. said the problem is most likely due to the position of the washer supply hose hood hinge clip in relation to the inline hose connector between the hood and main body hoses. The mispositioned connector causes the supply hose to be pinched by the hinge assembly when the hood is closed. Reorienting the connector so that it's in front of the hinge clip should eliminate further trouble.
Nissan
Drivers of 2002-03 2.5-liter Altima models with automatic transmissions may complain of a buzzing sound at 2,500 to 2,700 rpm under moderate acceleration.
Nissan Motor Co. reported that the most likely cause of the noise is the automatic transmission breather tank retaining bracket contacting the left/front subframe rail.
Begin the repair by removing the breather tank bolt. Next, order felt cloth tape, part #68370-4B000, and install it between the bracket and subframe rail. To complete the repair, reinstall and tighten the bracket bolt, then perform a road test on the vehicle to verify the buzzing noise has been eliminated.
Toyota
Some 2004-05 Land Cruisers may illuminate the check engine light and store oxygen sensor trouble codes P0136 and/or P0156 in computer memory.
If you can't find any obvious reason for the codes, Toyota Motor Corp. said, you're most likely dealing with software incompatibility issues in the powertrain control module. Having the module reprogrammed with updated software is the only sure-fire fix. Check with a dealer for the specifics.
