VS
Official Hummer service centre or specialist independent?
Quick summary: we use the same tooling and software as the official Hummer service network, but we repair batteries at module and cell level — something official workshops don't offer. On batteries, that means savings of 50–80%.
| Criteria | Official Hummer service | Taller Coche Eléctrico |
|---|---|---|
| Tooling & software | Manufacturer-grade | Manufacturer-grade, the same |
| Module/cell-level repair | Not offered: full pack swap | Yes — our speciality |
| Typical battery cost | €12,000 – €25,000 (full pack) | From €1,500 (module) |
| Warranty on the work | Per manufacturer | 2 years in writing |
| Quote | Subject to official scheduling | Fixed, in writing, within 24 h |
EU Regulation 461/2010 lets you keep your Hummer manufacturer warranty while servicing outside the official network, as long as the manufacturer's schedules are followed. That is how we work, and we document it in the exit report.
FAQ
Hummer frequently asked questions
How much does it cost to repair a Hummer battery?
It depends on the model and the damage: a module-level repair starts at €1,500, while a full Hummer pack can exceed €12,000 through the official channel. After diagnosis (from €60) you get a written fixed quote. In most cases the saving versus a full replacement is between 50% and 80%.
Do you repair Hummer in Barcelona and Madrid?
Yes. In Barcelona we are at Carrer del Tambor del Bruc, 3, Sant Joan Despí, next to exit 13 of the B-23. In Madrid, at Calle Valgrande, 17, Alcobendas, just off the A-1. Both sites work by appointment: WhatsApp 622 552 992 (BCN) or 665 245 143 (MAD).
Which Hummer models do you service?
We work on Hummer EV Pickup, Hummer EV SUV, among others. If your model isn't listed, message us anyway: as a multi-brand workshop with manufacturer-grade tooling we can service virtually any electric, plug-in hybrid or mild-hybrid Hummer.
Do I lose my Hummer warranty by not using the official service?
No. EU Regulation 461/2010 allows servicing at an independent workshop without losing the manufacturer warranty, provided the manufacturer's schedules are followed and equivalent-quality parts are used. We meet both conditions and document everything in the exit report.
What warranty do you give on Hummer repairs?
2 years in writing on repairs and installations. You also receive a technical report with diagnostic values before and after the intervention — useful if you sell the car or deal with your insurer.
