From the C-Class to the GLE, Mercedes-Benz vehicles deserve a shop that knows German engineering inside and out. Our Warwick technicians service every Mercedes model with the right Star Diagnosis scan tools, factory-spec parts, and 17 years of hands-on experience — at a fraction of dealership pricing.
Mercedes-Benz builds some of the most engineered vehicles on the road — but Rhode Island's climate doesn't go easy on them. Salt-coated winters near Conimicut, beach trips to Oakland Beach, and the rough patches of Route 117 all take a toll. Every Mercedes — C-Class, E-Class, S-Class, GLA, GLC, GLE, GLS, AMG models, Sprinter, or older C230, C300, E350 — has its own quirks. Knowing those quirks is what separates a shop that just works on Mercedes from one that actually understands them.
Primary Care Auto Repair has served Warwick, Cranston, East Greenwich, and the rest of Kent County for 17 years. Owner Jeff Roy and our technicians know the common Mercedes issues by heart — M272/M273 balance shaft failures, 7G-Tronic conductor plate leaks, AIRMATIC suspension sag, ML/GL coolant leaks, plastic intake manifold runner failures. We diagnose them quickly, fix them right, and skip the dealership prices. Most Mercedes service jobs are done same day at our shop on Locust Ave.
Every Mercedes service includes a free video inspection sent straight to your phone. You see the leaking valve cover, the worn arm bushing, or the cracked plastic coolant fitting before any work begins. That kind of straight-up communication is why Mercedes owners from Apponaug, Conimicut, Hoxsie, Cowesett, and Oakland Beach trust our Warwick auto shop with their luxury sedans and SUVs alike.
The shop sits at 33 Locust Ave, just off Post Road, minutes from Warwick Mall, T.F. Green Airport, and the Route 2 corridor. Easy access from I-95 and Route 117 makes drop-off simple from anywhere in Kent County. Whether your Mercedes needs a quick oil change or major drivetrain work, you'll get straight answers and honest pricing every time.

Mercedes owners know their vehicles aren't perfect — every model has its own pattern of issues. Here are the most common Mercedes problems we diagnose and fix at our Warwick shop.
The M272 V6 and M273 V8 engines (2005–2008) suffer from premature balance shaft gear wear. If ignored, this triggers timing codes and engine damage. We catch it early and replace with updated gears.
The 7G-Tronic 722.9 transmission is known for conductor plate failures that cause hard shifts, gear hunting, and limp mode. We replace the plate, fluid, and filter as a complete service.
S-Class, E-Class, GLE, and GLS models with AIRMATIC develop compressor failures, air strut leaks, and one-corner sag. We diagnose modules and replace only what actually needs it.
Mercedes uses plastic coolant fittings, valve covers, and oil filter housings that crack with age. Common across most M271, M272, M273, and M276 engines. We replace with quality parts.
The plastic intake manifold runners and air flap motors on M272/M273 engines fail with age, causing loss of power and check engine lights. We diagnose with Star Diagnosis and replace as needed.
BlueTEC diesel models (E350, GL350, ML350) develop DEF system, EGR, and SCR catalyst issues. We diagnose with factory-level scan tools and address the root cause — not just the warning light.
From routine maintenance to major repairs, our technicians handle every part of your Mercedes. C-Class, E-Class, S-Class, GLA, GLC, GLE, GLS, CLA, CLS, AMG, Sprinter — all models, all years.

A 2005 W211 E320 and a 2024 GLE 450 are completely different vehicles. Different engines, different transmissions, different electronic systems. Some Warwick shops only handle the easy stuff. We service the full Mercedes lineup — old and new — with the right Star Diagnosis tools, factory-spec parts, and the patience to diagnose properly. That's why so many Kent County Mercedes owners send their friends our way.

Quick answers to the Mercedes questions we hear most often at the shop.
Service costs depend on the job. Service A and Service B intervals, brake jobs, and routine maintenance are typically much less than dealership pricing. Bigger repairs like balance shafts or AIRMATIC work are quoted upfront after diagnosis. No surprises.
Yes. We perform full Service A and Service B intervals using factory-spec oil and filters, then reset the service indicator with Star Diagnosis so your dashboard shows the correct next-service date.
Yes. We work on every generation of Mercedes — including older W210 E-Class, W211, W203 C-Class, W163 ML, and W164. Older Mercedes have their own quirks, and our techs know them well.
No. We use factory-spec parts and Mercedes Star Diagnosis scan tools to handle most service jobs — usually for less than dealership pricing. Your warranty stays intact when service is done by qualified techs with proper documentation.
Most maintenance and routine repairs are same-day service. Bigger jobs like balance shaft replacement, conductor plate service, or AIRMATIC overhaul may need the vehicle for 2 to 5 days. We give a clear timeline at drop-off.
Yes. We service Mercedes AIRMATIC systems — compressors, air struts, height sensors, valve blocks, and modules. We diagnose the actual fault with Star Diagnosis before quoting parts.
From Apponaug Village to Oakland Beach, we keep Kent County Mercedes owners on the road. Walk-ins welcome when the schedule allows.
Honest Mercedes service in Warwick. Every model, every generation, every system. Free video inspection on every visit. Conveniently located near Route 2, Post Road, and I-95.
