General Motors
Drivers of 2008 Pontiac Solstice GXP models with 2.0-liter (VIN X) engines built before VIN breakpoint 8Y106569 may come into your store with several seemingly unrelated problems.
Among the complaints you might hear are that the fuel gauge reads differently when the vehicle is stationary as opposed to moving, or that the engine idles roughly and produces black smoke after a hot restart. Finally, the check engine light might be on with trouble codes P2610 and/or P0341 stored in computer memory.
According to GM, all these symptoms are the result of software incompatibility issues within the PCM. Reprogramming the module with updated calibration files is the only surefire fix. Check with a dealer for the specifics of the flash.
Chrysler
Owners of 2002 PT Cruisers with 2.5-liter diesel engines may complain that the engine lacks power and/or produces a squealing or sucking sound under acceleration. In some cases, an illuminated check Engine light may accompany the symptoms, with trouble code P0243 stored in PCM memory. Chrysler says one likely cause for all these troubles is a cracked or split intake inlet hose. Installing an upgraded inlet hose, Part No. 05080430AA, should eliminate the condition.
Acura
All 2005-06 RL sedans, as well as 2007 models built from VIN JH4KB1…7C000001 through JH4KB1…7C001724 may exhibit several drivability problems during unseasonably warm weather. Acura said the conditions are worse at higher altitudes, and the carmaker attributes them to fuel line vapor lock. Installing a new-design fuel pump (Part No. 17708-SJA-A02) and base gasket (Part No. 17574-SDC-L01) is the only reliable fix.
