Chrysler
Some 2007 Dodge Charger SRT8, Magnum SRT8 and Chrysler 300 SRT8 models with Hemi engines and AWD systems may produce strange electrical problems.
Among the comments you might hear is that the radio mysteriously stops working and/or the AWD system will not engage. Furthermore, if you hook up your scanner you might find trouble code B210D (low battery voltage) or B210E (high battery voltage) logged in computer memory. Software issues in the PCM are the root cause of all the woes. Reprogramming the module with new software is the only surefire remedy. Check with a dealer for the specifics of the flash.
General Motors
Some 2006-08 Buick Lucerne models with 3.8L engines may produce a buzzing noise or vibration from the brake and/or accelerator pedals. One likely cause for the annoyance, reports GM, is the fuel lines making direct contact with the brake booster. Installing a new-design fuel feed and evaporative emissions pipe assembly, Part No. 25978188, that routes underneath the booster should put the troubles to rest.
Toyota
Owners of 2005-11 Tacoma pickup trucks or 2007-11 FJ Cruiser SUVs with 6-speed manual transmissions may complain of a squeak or rattle from underneath the vehicle when the clutch pedal is released. Toyota attributes the noise to an improperly designed clutch release system, and has come up with a revised release bearing, fork and slave cylinder to remedy the condition. Note that there are two updated release bearings, depending on whether the truck is equipped with an Aisin or Luk pressure plate. You'll find the manufacturer's stamping on the outer edge of the plate. Here are the parts you'll need to complete the repair:
- FJ Cruiser/Tacoma – Release Bearing (Aisin) – Part No. 31230-60241
- FJ Cruiser/Tacoma – Release Bearing (Luk) – Part No. 31230-60231
- FJ Cruiser/Tacomoa – Release Fork – Part No. 31236-35050
- FJ Cruiser – Slave Cylinder – Part No. 31470-60361
- Tacoma – Slave Cylinder – Part No. 31470-35181
