Infiniti EX Repair in Salt Lake City, UT
The Infiniti EX35 and EX37 are compact luxury crossovers that used the same VQ35HR and VQ37VHR engines found in the G35 and G37 — a genuine performance DNA in a practical package. We service EX35 and EX37s regularly at our South Salt Lake shop, and the platform is well within our VQ-engine expertise.
Full-Service Infiniti EX Repair — All Generations
We service all Infiniti EX variants at our South Salt Lake shop — EX35 (2008–2012) and EX37 (2013), AWD and RWD. Every visit starts with a free diagnosis so you know exactly what your EX needs before we touch it.

Why Infiniti EX Drivers Choose Scott's Auto
The EX is an underrated platform — compact, capable, and powered by the same VQ engines that made the G35 and G37 respected sports cars. Owners who know what they have appreciate that it drives well and that parts availability is solid. We approach EX service with that respect for the platform's engineering heritage.
Deep VQ Engine Familiarity
We've serviced VQ35HR and VQ37VHR engines across the G35, G37, and EX platforms. The timing chain system, valve cover gasket patterns, and oil consumption characteristics are well-known to us.
AWD System Service
The EX AWD system uses an electronically controlled rear coupling. We service the rear differential fluid — a step many shops skip — and evaluate AWD engagement during the road test.
Compact Crossover Brake Expertise
The EX's compact footprint and lower curb weight make for a nimble brake system, but Utah canyon roads still wear pads faster than flat-road driving. We service brakes on the EX with the correct components for its size and weight.
Free Diagnosis, Written Estimate
Road test, code scan, inspection — free before we recommend any work. Written estimate, your approval, then we start.
When to Bring Your Infiniti EX In
EX35 and EX37 owners often find that parts availability is good and repair costs are reasonable because this platform shares so much with the G37. When an EX comes into our shop we road test it first — the VQ engines have a distinctive feel at high mileage that tells us a lot before the codes are even pulled. Below are the issues we see most consistently on this platform.
Timing Chain Rattle — VQ35HR and VQ37VHR
The EX shares its timing chain vulnerabilities with the G35 and G37. High-mileage engines that have seen inconsistent oil changes develop chain stretch and tensioner wear. A cold-start metallic rattle that fades once oil pressure builds is the key symptom. We assess the chain and tensioner condition before recommending a repair scope.
Learn more →CV Axle and Joint Service
EX CV boots crack over time — a natural consequence of the compact crossover's range of suspension articulation. Once grease escapes and grit enters, joint wear accelerates quickly. The clicking-on-turns symptom is the classic indicator. We replace the complete axle shaft.
Learn more →Brake Service — Pads, Rotors, and Calipers
The EX's rear brakes are more commonly serviced than the fronts on cars that have done a lot of highway driving. We inspect all four corners and check rear caliper slide pins for corrosion-related seizing — a common issue in Utah's winter salt environment.
Learn more →Strut Replacement
The EX's sport-influenced suspension tune results in struts that wear noticeably when they've passed their useful life — road noise increases, and rough pavement that used to be manageable becomes more intrusive. We replace struts as a set when they've lost their damping ability.
Learn more →Exhaust and Catalytic Converter Codes
High-mileage EX35 and EX37 models develop catalyst efficiency codes as the converters age. We verify whether it's the cat or an O2 sensor before quoting replacement — this step saves money on an otherwise expensive repair.

Utah's temperature swings, mountain roads, and high altitude put unique demands on your vehicle. Here's what we've learned from years of servicing Infiniti EXs in the Salt Lake Valley.
EX35 and EX37 timing chain longevity depends almost entirely on oil change consistency — use a quality full-synthetic and change it every 5,000 miles. The VQ engine's chain tensioners rely on oil pressure, and degraded oil shortens their life significantly.
AWD EX owners: the rear differential fluid is a separate service from the engine oil and transmission fluid. Have it changed every 30,000 miles — most shops skip it because it's not on a standard maintenance checklist.
Utah's road salt corrodes EX rear brake caliper slide pins faster than dry-climate owners experience. Have the rear brake hardware cleaned and lubricated at every brake service to prevent uneven pad wear and seized pistons.
