Cadillac major and minor service
Each scheduled visit covers the inspection and replacement items set for the odometer reading, and we renew any worn part found along the way. A 2025 CT5 is due new wiper blades every 20,000 km, with spark plugs replaced at 90,000 km. The rear axle fluid of a CT5 with a limited-slip differential is changed every 70,000 km.

Cadillac oil services
We empty the sump, change the filter element and pour in the viscosity grade set for the engine. A 2025 CT5 holds 5.0 litres of SAE 0W-20 in its 2.0 litre LSY, against 5.7 litres of 5W-30 in the LGY V6. On a 2023 XT5, the 2.0 litre runs on SAE 0W-20 and the 3.6 litre V6 on SAE 5W-30.

Cadillac engine repair
We follow misfires, lifter noise and fluid leaks on Cadillac V8, V6 and turbo 4-cylinder engines back to the failed component and replace it. The 2026 Escalade runs the 6.2 litre L87 V8 of 313 kW or the supercharged 6.2 litre LT4 of 509 kW. A 2025 CT5 has the 2.0 litre LSY turbo of 177 kW or the 3.0 litre LGY twin-turbo V6 of 250 kW.

Cadillac transmission service and gearbox inspection
Gearbox work starts from the stored codes, and we then fix the leaking seal or cooler pipe and renew the fluid and filter. The 2026 Escalade uses DEXRON ULV fluid, changed with its filter every 70,000 km in severe service. Its V-Series transfer case fluid is due every 80,000 km, or every 40,000 km under severe use.

Cadillac brake repair
We measure pad and disc wear, renew both at their limit and reset the Brake Pad Life display on a 2025 CT5. Every 2025 CT5 except the J57 Blackwing has pads with built-in wear indicators. The 2026 Escalade runs on DOT 4 fluid, and the 2026 Escalade-V stops on 40 cm rotors.

Cadillac suspension repair and wheel alignment
Worn tie rods, control arm bushes and dampers are replaced, and a wheel and steering alignment closes each job that alters the geometry. On the 2026 Escalade, air suspension gives full-time load levelling and an adjustable ride height, and Magnetic Ride Control, where fitted, damps semi-actively. We refer Magnetic Ride work that needs GM tools to a Cadillac dealer.

Cadillac AC service and repair
After tracing the leak, we replace whichever compressor, condenser or pipe has failed. The refill then follows the refrigerant type and charge printed on the under-bonnet label. The 2026 Escalade and 2026 Lyriq manuals leave both figures to that label.

Cadillac battery change and electrical repair
We check the battery's charge and the alternator output before replacing either, and repair the wire, connector or module behind an electrical fault. On a 2026 Escalade, we choose the new battery from the replacement number shown on the old one's label. A 2019 CT6 hides its AGM battery under the spare tyre, and a 2019 CTS behind the driver-side boot trim.

Cadillac electric vehicle service
On the Lyriq, Optiq, Vistiq and Escalade IQ, we service the brakes, tyres, suspension and 12-volt battery. The 2026 Lyriq manual leaves inspection, testing and replacement of the high-voltage battery to a specialist technician. So high-voltage work on every electric Cadillac goes to a Cadillac dealer.
