What we repair
What we repair and service on your Hummer
Under the armour, the H2 and H3 use proven GM truck hardware: small block V8s, Hydra Matic gearboxes and familiar electrics. That keeps most Hummer repairs practical, quoted in writing after a free inspection.
Scrapes, dents and sun faded paint on big panels. We repair and paint, then check lights, sensors and cameras work.
Common faults by model
Hummer faults we look for, H2 to H1
Most Hummers in Dubai are now 15 to 20 years old, so the same faults repeat. These are the ones owner reports and repair data point to, with what we check first.
No published UAE recall for these older models came up in our checks. We confirm open campaigns by VIN with GMC before any paid work.
Sign: the back sits low after parking, reported by owners of air equipped H2s. We: test the air springs, lines, compressor and height sensor before quoting.
A Hummer weighing two to four tonnes that loses brakes or overheats is a bigger problem than a small car doing the same. Use these levels to decide, and send us a dash photo if unsure.
Stop driving
Temperature in the redSwitch off. A big V8 or diesel can warp heads in minutes. Call us for recovery and a pressure test.
Brake pedal sinks or ABS light with poor brakingOn a vehicle this heavy, braking problems come first. Do not drive it, we arrange recovery.
Hummer EV battery or propulsion warningPark safely and contact Al Ghandi Auto or GMC roadside assistance. High voltage faults are dealer work.
Book this week
Flashing or steady engine lightOn the H3 a misfire can mean burnt valves. An early leakdown test keeps the repair smaller.
Service 4WD messageThe transfer case may not shift. Avoid sand and wet ramps until the shift motor and encoder are checked.
Rear sitting lowOn an air equipped H2, a leaking spring overworks the compressor. Book before the compressor fails too.
Drive in soon
AC weaker or wrong ventsOften a blend door actuator on the H2, or a slow leak. Testing now beats peak summer queues.
Oil spots under the frontA front differential or transfer case seal leak. Cheap to reseal early, costly if the unit runs low.
Wander or clunks over bumpsWorn steering linkage or bushes also eat expensive tyres. We inspect on the lift and quote worn parts only.
V8, five cylinder or diesel: what drives your Hummer
Each Hummer generation uses a different GM drivetrain, and the year decides which gearbox you have. Knowing yours tells us where to look first and which parts fit.
4L60E / 4L65E four speed, H2 and H36L80 six speed, 2008 to 2009 H24L80E / Allison H1
The new Hummer is a GMC, built on GM's Ultium platform with CrabWalk and Extract Mode. Much of it is heavy truck hardware we can service, but high voltage work stays with the dealer.
On 14 October 2026, dubizzle Dubai listed 16 used Hummers: seven H2, six H3 and three H1. Another nine sat under GMC as Hummer models. Here is what to watch on each.
Asking prices seen: a 2007 H2 at AED 55,000 and a 2007 H3 Alpha at AED 15,000. A 2009 H2 listed new in the UAE from AED 250,000, per DriveArabia. No H3T was listed. We also see the HX query, but the HX was a 2008 concept only.

GMC dealer or an independent garage: who fixes your Hummer
Hummer as a brand ended in 2010, so the H1, H2 and H3 have long left factory cover. The new Hummer EV is sold through GMC, and Al Ghandi Auto is the GMC dealer in Dubai.

Used car inspection
Buying a used Hummer? Six checks before you pay
A cheap Hummer can turn expensive fast. With only a handful for sale in Dubai, sellers rarely negotiate, so these six checks give you facts and a written report first.
VIN and historyWe decode the VIN to confirm model, engine and gearbox, and check service records and GCC or import origin.
Air suspension overnightOn air equipped H2s we check the rear holds height overnight and the compressor runs and stops normally.
Engine leakdownOn the H3 five cylinder we test compression and leakdown, because burnt valves cost thousands to put right.
4x4 systemWe shift through high and low range, check the transfer case and front axle for leaks, and listen for clunks.
Cooling and ACWe pressure test cooling and measure vent temperatures, including every blend door and the H2 rear AC.
Frame and underbodyOn the lift we look for rust, impact damage from off road use, worn steering linkage and leaking seals.
From first message to collection, you know what you get at each step, whether the job belongs at the dealer and what it costs. Nothing starts without your approval.

A short history
From Humvee to electric GMC: Hummer in six dates
Hummer started as a civilian version of a military truck, became a GM brand, closed in 2010 and returned as an electric GMC. That history decides who fixes which model today.
1992
AM General starts selling the civilian Hummer, based on the military Humvee.
1999
GM buys the Hummer name in December, keeping AM General as builder.
2002
H2 production begins on GM truck hardware.
2005
H3 production starts, based on the Colorado pickup.
2010
A sale falls through and the last H3T leaves the line on 24 May.
2020
The GMC Hummer EV is revealed on 20 October, an electric revival.

Where can I get my Hummer repaired in Dubai outside the dealer?
Mechanics in Al Quoz is an independent Hummer workshop for the H1, H2, H3 and H3T, covering servicing, air suspension, engine, gearbox, 4x4, AC and electrics. You get a free inspection and a written quote first. Hummer EV warranty and high voltage work stays with Al Ghandi Auto, the GMC dealer.
How much does a Hummer service cost in Dubai?
A Hummer service in Dubai starts from about AED 349 for one online garage's major service package, as a guide, while dubizzle lists AED 1,000 to 1,200 for a full service on any car. A V8 takes more oil and filters, so we quote your Hummer in writing.
Why does my Hummer H2 sit low at the back?
A low rear on an H2 usually means a leaking rear air spring, a split air line or a tired compressor, on cars with the optional self leveling rear air suspension. Owners report it lowering overnight. We test springs, lines, compressor and the height sensor before quoting.
Why does my Hummer H3 misfire with the engine light on?
An H3 misfire with code P0300 often points to burnt or leaking valves on the five cylinder engine, a pattern owners report around 50,000 to 140,000 miles. We confirm it with compression and leakdown tests before quoting a valve job or cylinder head.
Can you still get parts for a Hummer H2 or H3 in Dubai?
Yes, for most jobs. The H2 uses GM full size truck hardware such as the Vortec V8 and Hydra Matic gearboxes, and the H3 shares its base with the Chevrolet Colorado. Body panels and trim are harder, so we confirm parts and lead time in writing.
Does my Hummer H2 have a four speed or six speed gearbox?
It depends on the year. H2s from 2003 to 2007 use a four speed automatic, the 4L60E and then the 4L65E, with the 6.0 V8. The 2008 and 2009 H2 has the 6.2 V8 and a 6L80 six speed. We confirm by VIN and service it accordingly.
Who services the GMC Hummer EV in Dubai?
Al Ghandi Auto, the GMC dealer in Dubai, handles Hummer EV warranty, recalls, software and all high voltage work. We look after the rest of the vehicle after cover: brakes, tyres, alignment, air suspension checks, the 12V battery and body work on this heavy electric truck.
Why is the ABS light on in my Hummer H2?
An ABS light on an H2 often comes from the ABS module (EBCM) failing internally or losing communication, a known fault on 2003 to 2007 models. A wheel speed sensor is the other common cause. We scan the module and test sensors and wiring before replacing parts.
Can you work on a Hummer H1 diesel?
Yes. We service and repair the H1's 6.5 turbo diesel, gearbox, cooling, brakes and steering. Its pump mounted fuel driver is known to overheat and cut the engine, and we test it first. Duramax Alpha parts and geared hub work are quoted after inspection.
How long does a Hummer repair take?
Servicing, brakes, batteries and AC checks are usually short visits. Air suspension, valve, gearbox or 4x4 faults need diagnosis first, and some parts are ordered in, so lead time often matters more than labour. We give you the expected time and parts lead time in writing.
Is it worth repairing an old Hummer H2?
Usually yes, if the frame and body are sound. A used 2007 H2 was listed at about AED 55,000 in Dubai, so most repairs cost far less than the value lost selling it faulty. Rust, crash damage or a failed engine and gearbox together change the answer.
Can you inspect a used Hummer before I buy it?
Yes. We decode the VIN, check the rear air suspension overnight on H2s, run a leakdown test on H3 engines, test the 4x4 system, cooling and AC, and inspect the frame on the lift, then give a written report. Only 16 used Hummers were on dubizzle Dubai.
