According to Au7o's analysis of 4,480+ owner reports, the 2007 Jaguar S-TYPE has 3 documented known issues, with 1 rated critical. The most serious is Timing Chain Tensioner Failure on V8 Engine ($3,500-$7,000 repair). The most commonly reported issue is Electrical System Gremlins and Module Failures with 2,100 owner reports. Across all issues with published estimates, repair costs range from $200 to $7,000. DIY maintenance guides at au7o.io.
On the 2000-2008 Jaguar S-TYPE, the early AJ-V8 engines in the S-TYPE have timing chain tensioners that fail prematurely, producing a characteristic cold-start rattle. The tensioners lose hydraulic pressure overnight, allowing chain slack that wears the guides and stretches the chain progressively.
Replace the timing chain tensioners, chains, and guides. On the S-TYPE, the engine does not need to come out but front-end disassembly is extensive. Use updated tensioner part numbers. Budget 18-24 hours of labor.
Owner tips & cautions
WarningThe S-TYPE V8 timing chain job costs more than many of these cars are worth. Factor this into your purchase price or walk away from one with cold-start rattle.

On the 2000-2008 Jaguar S-TYPE, the S-TYPE is notorious for electrical gremlins caused by moisture ingress into control modules and poor CAN bus connections. Phantom warning lights, inoperative features, and intermittent faults across multiple systems are common and difficult to diagnose without dealer-level equipment.
Check all module locations for moisture ingress, particularly the driver footwell and trunk. Clean and reseal all CAN bus connectors with dielectric grease. Reprogram affected modules with the latest software. Replace the 12V battery if it is over 4 years old.
Owner tips & cautions
TipBuy an iCarsoft i930 Jaguar-specific scanner. It reads all Jaguar modules and saves thousands in dealer diagnostic fees. Essential tool for S-TYPE ownership.

On the 2000-2008 Jaguar S-TYPE, the ZF 5HP and 6HP automatic transmissions in the S-TYPE develop valve body wear, causing harsh shifts, slipping between gears, and delayed engagement from park. The Ford JF506E used in some V6 models also suffers from similar solenoid-related issues.
Rebuild or replace the valve body. Change the transmission fluid and filter, which may temporarily improve shift quality. For the ZF 5HP/6HP, use only ZF-specified fluid. For the JF506E, a solenoid pack replacement often resolves the issue.
Owner tips & cautions
TipChange the transmission fluid every 40,000 miles regardless of what the manual says about lifetime fill. This extends valve body life dramatically on both the ZF and Ford transmissions.
