2007 Isuzu I

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 I.

Transmission Automatic 4-spd

The 2007 Isuzu I-370, underpinned by the 370 platform, is a model equipped with a conventional automatic four-speed transmission that yields an EPA-estimated 18 combined mpg from its 15 city and 22 highway ratings. This straightforward mechanical package is mirrored by the vehicle's exceptional reliability record for the year, as it incurred zero recalls and logged only a single owner complaint directed at the electrical system. Consequently, the 2007 model year sits as a notably trouble-free chapter in the vehicle's history, offering researchers a clear example of the platform's fundamental dependability.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2007 Isuzu I dominate in one area — the electrical system, 1 of 1 reports (100%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the electrical system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
