Cooling Your Tacoma’s Backseat: A Simple Heat Reduction Tip

2026 Tacoma Trailhunter - “Hybrid System Stopped” + “Steering Power Low” at only 355 miles

Bought a new 2026 Tacoma Trailhunter about 6 weeks ago. Currently at 355 miles. I had a professional install two Motohorn train horns, Gasoray kill switch, fang lights, two auxiliary lights, and a heads-up display. I dropped it off to get PPF wrapped. When I picked it up and started it, the RPMs were fluttering up and down, almost dying, then fluttering again. When I tried to leave the parking lot, I had no acceleration at all and had to coast to a stop. The dash showed: • Hybrid System Stopped • Steering Power Low Dealer scanned it and the hybrid battery is only showing 12%. The tech said he’s never seen this before and there are no diagnostic codes stored. He explained that because the kill switch completely powers down the entire truck, the system can’t keep any codes stored — the system needs to stay powered on / running in the background for diagnostic codes to remain. They’re telling me they might need to order a special Toyota hybrid battery charger, that I may have to pay for a license to use it, and that I shouldn’t expect the truck back by this weekend. They also want me to approve 4 hours of diagnostics ($920) before they’ll even start working on it. Has anyone seen this on a new hybrid Tacoma, especially with a kill switch installed? Any advice is appreciated.

I've read online that it is normal for the back seat of your truck to warm up because of the battery. Well, that's not really the case and wanted to share a simple tip for it.

I found out that if you put the heat and cooling system on the floor blowing mode, it helps to reduce the heat for the rear seat of your truck.

I know Tacos have a vent for the rear passengers under the front seats. Which can be used to control the temperature back there. Figured this would be a useful tip for anyone who might be facing such.
