2007 Chevrolet W3500 problems
The Isuzu Elf (Japanese: いすゞ・エルフ, Isuzu Erufu) is a medium duty truck produced by Isuzu since 1959. Outside Japan it is known as N series and Q Series. The range was originally mainly available in Japan and other Asian countries. Australia was another important market for the Elf and N series – to the extent that it was manufactured there from the 1970s using many local components. Since the early 1980s, it has also been sold and built in the United States (under the Chevrolet and GMC brands as a W-Series), and also as the Isuzu N-Series. Only North America receives the wide-cab version.
For the common Andinian market (including Chile and Peru), the truck has been assembled in the GM-Colmotores assembling plant in Bogotá, Colombia since 1991, with annual quantities already of 20,000 up to 60,000 units. Local assembly has been increasing because of increasing demand in the Colombian and neighboring markets. It carries "Tecnología Isuzu" (with Isuzu Technology) lettering.
In Indonesia, Philippines and several other countries, the Elf is not only used as a truck, but also converted into microbuses by local body makers. The lighter four-wheeled models are commonly used as an intercity Angkot or Jeepney (share taxis), as a school bus, or as an employee bus. Indonesian conversions typically use car-style hinged doors and usually resemble a high-roof van, while most conversions in Kenya, and newer ones in the Philippines often resemble a minibus, with a folding door on the side for passengers, and standing room.

Common 2007 Chevrolet W3500 problems
The Chevrolet W3500 2007, also known as the Isuzu NPR, has been reported to have several common problems based on complaints from its owners. One major issue is the loss of power and fuel economy after the transmission control module (TCM) was updated by Isuzu. The owner of the vehicle reported a significant decrease in fuel efficiency, from almost 15 miles per gallon (mpg) to 9 mpg, and a noticeable loss of power. The exhaust pipe also turned black and wet inside, and the entire exhaust system turned multiple shades of purple. This issue was not resolved despite multiple visits from Isuzu technicians who confirmed that the computer was working perfectly.
Another problem reported by owners is the inability to reach full throttle, even with the pedal to the floor. This issue is particularly noticeable in hilly terrain, where the vehicle requires a lower gear to maintain speed. One possible cause for this issue is a plugged-up catalytic converter (CAT) or muffler, which can be diagnosed by pulling an O2 sensor and checking the back pressure.
The 2007 Isuzu NPR owner's manual provides several recommendations for daily checks before driving the vehicle. These checks include looking for fluid leaks, ensuring that the tilt cab is securely locked in the lowered position, inspecting the exhaust system, and checking that all lights work. The manual also recommends checking the area under the truck and behind it if you are about to back up.
A technical service bulletin (TSB) is a document that identifies an unanticipated vehicle or part issue and provides a solution. While a recall concerns a safety issue which must be fixed, a Technical Service Bulletin just identifies a common issue and documents a solution. The circulation of the bulletin amongst dealerships and manufacturers can help diagnose the issue and lead to faster and more efficient fixes.
In summary, the Chevrolet W3500 2007 has been reported to have several common problems, including a loss of power and fuel economy after a TCM update, the inability to reach full throttle, and issues with the exhaust system. Daily checks before driving the vehicle, as recommended in the owner's manual, can help identify and prevent some of these issues. Technical Service Bulletins can also provide solutions to common issues and help diagnose problems more efficiently.
