We service and repair Hummer vehicles at our workshop in Al Quoz Industrial Area 2, with free collection across Dubai during working hours. The Hummer H2 and H3 are imposing American 4x4s built for extreme off-road terrain, but Dubai heat and desert sand take a heavy toll on their heavy-duty automatic transmissions, rear air suspension bladders, steering linkages and braking systems.
We provide routine minor oil services for inline-5, V6 and V8 models, major service packages, transmission rebuilds, differential servicing and suspension repairs. We cure air suspension sag, replace worn brake pads and rotors, resolve cooling leaks and restore ice-cold AC. Every service begins with an itemised WhatsApp quote before any work starts.
Hummer models we see most
-
Hummer H2 (6.0 & 6.2 V8)
Massive 3-tonne SUV; rear air suspension compressors and bellows leak with age, 4L65E/6L80 transmissions run hot in soft sand, and heavy brakes wear quickly.
-
Hummer H3 (3.5, 3.7 & 5.3 V8)
Mid-size 4x4; inline-5 cylinder head valve seat wear on earlier engines, front differential crossmember bushing tears, and steering rack mounts soften.
-
Hummer H2 SUT
Pickup variant; midgate weather seals dry out in summer sun, and rear air leveling sensors need calibration against road dust.
-
Hummer EV
Modern electric super-truck; high-voltage battery thermal management, air suspension height calibration and 4-wheel CrabWalk steering diagnostics.
Common Hummer faults in Dubai
-
Rear air suspension sagging overnight on Hummer H2
The rubber air bellows perish from age, heat and sand abrasion, losing pressure when parked. The underbody compressor runs continuously trying to level the truck until the motor burns out.
-
4L65E transmission slipping or overheating in sand driving
Extreme desert sand driving overheats transmission oil, wearing the 3-4 clutch pack and 2-4 band. Fitting an auxiliary transmission cooler and fresh fluid protects the gearbox.
-
Front suspension pitman arm, idler arm and ball joint wear
Due to massive tyre size and curb weight, the front steering linkages on the H2 wear their grease joints rapidly, creating steering wander and front-end clunking.
-
Exhaust manifold bolt breakage on 6.0L and 6.2L V8
Thermal expansion cycles snap the rear exhaust manifold bolts flush with the cylinder head, creating a sharp exhaust tick that is loudest when the engine is cold.
-
AC blowing warm air when idling in traffic
The massive interior volume of the H2 requires a fully charged AC system. Dust-coated condensers and weak viscous fan clutches cause cooling to drop significantly at idle.
Hummer questions
How much does a Hummer oil change cost at Gomaa Garage?
Synthetic engine oil and filter changes for Hummer are carried out using fully synthetic oil and an original filter for inline-5 and V8 engines. Check current package pricing below or message us on WhatsApp.
Can you convert Hummer H2 rear air suspension to coil springs?
Yes. If your H2 air compressor and air bags have failed, we can install a heavy-duty rear coil spring conversion kit that eliminates air leaks permanently, or replace the air bellows with genuine units.
Do you use genuine GM parts for Hummer?
Yes. We supply genuine GM and ACDelco parts, as well as heavy-duty aftermarket components for steering and suspension. We list all parts and labour clearly on your WhatsApp quote.
Do you offer pickup across Dubai for Hummer vehicles?
Yes. Free pickup is included anywhere in Dubai during working hours. Send your location on WhatsApp and we will collect the car.
