The second-generation Tucson, sold as ix35 in most of Europe, was a major step forward for Hyundai in the compact SUV segment. The 2.0 CVVT G4KD is the Theta II family multi-point injection petrol engine producing 163 hp, offered with manual or 6-speed automatic and optional on-demand AWD. It uses a timing chain instead of a belt, which removes one big scheduled expense but introduces tensioner wear as a known concern after 120,000 km.
Timing chain, no belt to change
Cheap parts, simple MPI engine
Theta II oil-burn on some cars
ABS/ESP fire recall needs checking
Buy if: You want a straightforward petrol SUV with cheap parts, a documented oil-consumption test history, and confirmation that all safety recalls have been completed.
Avoid if: You find an example with cold-start rattle, oil level below minimum, or an unverified ABS fire recall status.

Common Problems
Some examples burn more than 1 litre per 1,000 km due to cylinder bore scoring or rod-bearing wear · more· less
A subset of 2010-2013 LM ix35 cars with the G4KD Theta II MPI engine have shown excessive oil consumption (more than 1 litre per 1,000 km) and engine knocking traced to cylinder bore scoring and connecting rod bearing wear. Root cause is linked to rough crankshaft machining and metal debris from the manufacturing process, which can clog oil passages and starve bearings. Hyundai conducted extensive engine-replacement campaigns in North America for the Theta II family, but European LM petrol cars were largely not covered by the main extended-warranty programs, so out-of-warranty repairs fall to the owner. If caught early, a full engine replacement at an authorized workshop runs €6,000-8,000; at high mileage with documented repair history, the risk drops significantly. Always run an oil-consumption check: top up to full, drive 1,000 km in normal conditions, re-measure.
Hydraulic tensioner loses pressure overnight, causing a cold-start rattle typically after 120,000 km · more· less
The G4KD uses a timing chain with a hydraulic tensioner. As the tensioner ages, it loses the ability to hold oil pressure overnight, and the guides wear. This produces a characteristic metallic rattle for 1-3 seconds on cold start that usually disappears once oil pressure builds. Forum reports on hyundai-forums.com place this failure between 140,000 and 200,000 km. If the rattle persists beyond a few seconds or gets louder, the chain, guides, and tensioner need replacing together — ignoring it risks chain skip and valve/piston contact. A full chain service at an independent workshop costs €1,000-1,500; at a Hyundai dealer €1,800-2,200. If the chain skips and valves are bent, expect €3,000+ in additional engine work.
Moisture ingress through contaminated brake fluid can short-circuit the ABS module and ignite an engine-bay fire · more· less
This is the subject of a Europe-wide recall affecting ix35 models built between 2013 and 2015, and several overlapping campaigns covering earlier LM production. Brake-fluid contamination damages O-rings, allowing fluid into the ABS control board, where electrical current and the flammable residue can cause a fire. The fix is a software update plus inspection and, if needed, control module replacement — free of charge at a Hyundai dealer. Many cars still circulate without the repair completed; insurers have flagged this as a non-trivial fire risk. Always verify recall status with the VIN before buying. The cost listed is only for brake-fluid service if the buyer wants to freshen the system as a precaution.
Compressor clutch coil or condenser leaks after 100,000 km, particularly in hot climates · more· less
The AC compressor on the ix35/Tucson LM is a known weak point. Two failure modes are common: the electromagnetic clutch coil burns out, leaving no cold air, or the condenser develops leaks at the solder joints. Forum reports show failures concentrated between 100,000 and 150,000 km. A new aftermarket compressor costs €200-350 and labour plus refrigerant adds €200-500; a condenser is €120-200 plus labour. In about 30% of cases, the issue is only a corroded electrical connector that can be cleaned for minimal cost — always have it diagnosed before replacing parts.
Upper strut mounts, lower ball joints, and anti-roll bar links wear between 80,000 and 120,000 km · more· less
A distinctive knock or clunk from the front end over bumps is widely reported on the LM. The most common causes are worn upper strut mounts (the top bearing between the strut and body) and lower ball joints. Anti-roll bar drop links typically wear first and are cheap to replace (€40-80 per side). Strut mounts run €60-100 each plus 2-3 hours labour; ball joints €80-150 each plus 2 hours. In European climates, road salt accelerates the wear. A full front-end refresh (strut mounts, ball joints, drop links, bushings) at an independent workshop is €500-800. TÜV/APK inspectors often flag these components first.
Electronic parking brake actuator or rear caliper seizes, typically after 80,000-100,000 km · more· less
Higher-trim LM models use an electronic parking brake (EPB) with motor-operated actuators on the rear calipers. After 80,000-100,000 km the motors can seize, or the rear caliper slide pins can corrode and cause uneven pad wear. Symptoms include an EPB warning light, inability to release the handbrake, or pulling under braking. A single EPB actuator replacement is €250-400 including labour; rear caliper replacement is €300-600 per side with OEM parts. Aftermarket calipers reduce cost by about 30%. On manual handbrake versions this risk does not apply.
Good bones, but Theta II oil-burn and recall status are the deciding factors
The Tucson LM 2.0 petrol is mechanically simpler than most rivals of its era: timing chain (no belt service), naturally aspirated (no turbo), and no DPF. A well-maintained front-wheel-drive example with documented recall work and a clean oil-consumption test is an affordable, reasonable buyer. The deciding factor is the Theta II engine lottery — most cars are fine, but a minority consume oil heavily due to bore scoring, and out-of-warranty engine replacement is prohibitively expensive. Verify the ABS fire recall has been done, run a proper oil-consumption test, and listen carefully for timing chain rattle on cold start.

Verify completed
Contact a Hyundai dealer with the VIN to verify all recalls have been completed. The ABS/ESP fire-risk recall is particularly critical for the 2010-2015 LM ix35/Tucson and should never be skipped.
Warranty Status
Factory warranty (5 years / unlimited km)
Expired on all LM models
Rust perforation warranty
Expired (was 6 years from first registration)
Theta II engine extended warranty
Not extended to European LM petrol cars
All LM Tucson and ix35 models (2010-2015) are beyond their 5-year factory warranty. The Theta II engine extended warranty program operated primarily in North America and was not applied to European LM petrol cars. A third-party extended warranty can be worth considering given the Theta II oil-burn risk.
