2017–2019 Chevrolet and Isuzu: electrical system recall

A stall can increase the risk of a crash.

high 16,766 vehicles affected 55% reported repaired

What was reported

Source: manufacturer filing, 49 CFR Part 573
Problem Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2017-2019 N-GAS HD and Chevrolet Low Cab Forward 3500 and 4500 vehicles and 2018-2019 Isuzu FTR and Chevrolet Low Cab Forward 6500XD vehicles. The power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to a stall. Risk A stall can increase the risk of a crash. Fix Isuzu will notify owners, and dealers will inspect the relay box power supply bolt, tightening it as necessary. If the harness or relay box is found to be damaged, it will be replaced or repaired, free of charge. The recall began October 24, 2019. Owners may contact Isuzu customer service at 1-866-441-9638. Isuzu's number for this recall is V1905.

Reported to NHTSA Sep 9, 2019 by Isuzu Technical Center of America, Inc, owners notified Oct 24, 2019.

None of the vehicles this campaign names has a page on WhichTrim: the catalogue covers the cars, trucks and SUVs the EPA certifies from 2016 on, and these vehicles fall outside it — older model years, or motorhomes, trailers, buses, motorcycles and chassis cabs the EPA does not rate. The campaign record above is complete as filed, and whether one specific vehicle is included is settled by its VIN. Other campaigns on vehicles without a page here →

How much of it has been fixed

Source: manufacturer quarterly report, 49 CFR 573.7
Reported repaired 55%

of the campaign

The final figure: the six quarters of reporting that 49 cfr 573.7 requires have closed.

This is the manufacturer's own cumulative count of vehicles it has inspected and repaired, divided by the vehicles the campaign covers. It files that count with NHTSA every quarter for six consecutive quarters, starting from the quarter in which owners were told a remedy was ready, and then the obligation ends — so a figure on an older campaign is where the count stopped, not where it stands today.

It rarely reaches 100%, and not because the work was not done. The same report asks manufacturers to count vehicles they could not reach at all — exported, stolen, scrapped, or simply never located — and those stay in the denominator. A low number means a lot of these vehicles are still out there unrepaired; it does not tell you which ones.

Check one specific vehicle

A recall applies to a build range, so year, make and model cannot settle it. NHTSA checks a VIN against the manufacturer's own list and tells you whether the repair is still outstanding on that vehicle.

Common questions

Source: NHTSA, 49 CFR Part 573

Is V1905 the same recall as 19V647000?

Yes. V1905 is the number Isuzu Technical Center of America, Inc uses for this campaign in its own paperwork and in the letter it sends owners. 19V647000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.

Does this recall repair cost anything?

No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.

How do I know whether my vehicle is included?

By VIN, not by model year. This campaign covers vehicles built Oct 31, 2017 to Dec 20, 2018. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.

What if the repair is not available yet?

It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.

What did the manufacturer say was wrong?

The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.

Who started this recall?

NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
