The Nissan Pulsar has had two distinct lives in Australia. The N16 generation (2000–2006) was a mainstream small car powered by the 1.6-litre QG16DE or 1.8-litre QG18DE four-cylinder, paired with a four-speed automatic or five-speed manual. After a long absence, Nissan revived the nameplate with the B17 sedan (2013–2017) and C12 hatchback (2013–2017), offering a 1.8-litre MR18DE or a turbocharged 1.6-litre HR16DE DIG-T, both available with a JF015E CVT automatic. The N16 built a solid reputation for everyday reliability, though at 20-plus years old, deferred maintenance is now the main risk. The B17/C12 generation had a more troubled reception, with CVT failures emerging as a well-documented complaint. With the right checks, either generation can still make a sensible used buy.
N16 engine issues: coil packs, head gasket, and sensors
The N16's 1.8-litre QG18DE is the engine most frequently discussed on Australian owner forums, and it has a couple of known weak points that buyers should check for.
Ignition coil pack failure
The individual coil-on-plug units fitted to the QG18DE are a recognised fault point. Owners report rough idle, cylinder misfires (typically P0300–P0303 fault codes), and hesitation under load. A failing coil will often take the corresponding spark plug with it — look for black streaks on the plug's porcelain and grey marks inside the coil boot. Replacing a single coil costs roughly $80–$180 for a quality part; doing all four at once on a high-kilometre car avoids repeat visits. Genuine or OEM-quality units are recommended, as cheap aftermarket coils can trigger ongoing codes.
Head gasket (1.8-litre QG18DE)
The QG18DE's head gasket is a documented weakness, confirmed across multiple Australian owner forums. Prolonged driving with misfiring coil packs can accelerate the problem. Symptoms include white exhaust smoke on startup, milky oil cap residue, rising coolant temperature, or unexplained coolant loss. A head gasket replacement on an N16 typically costs $900–$1,800 at an independent workshop, depending on whether a head skim is required.
Crank angle sensor (pre-2002 N16s)
The crankshaft position sensor (CAS) is a known fault on N16 models built before approximately mid-2002. A failing CAS causes intermittent no-start conditions or stalling when hot — the car may start fine cold and refuse to restart after a brief stop. Nissan issued a recall for this component on early N16s. Replacing it with a genuine or OEM-quality part is recommended; cheap aftermarket sensors have a history of re-triggering fault codes on this engine. Cost: roughly $150–$300 fitted.
N16 cooling system and suspension wear
Radiator and coolant system
The plastic end-tanks on the N16's original radiator are prone to cracking with age, causing coolant leaks. Rust build-up inside the lower coolant hose connection to the water pump has also been reported, reducing flow and eventually causing overheating. On any N16 approaching 200,000 km, the radiator, thermostat, and hoses are worth inspecting closely. A replacement radiator typically costs $250–$500 supplied and fitted by an independent mechanic.
Sway bar and control arm bushes
Suspension bush wear is an expected maintenance item on a car that is now over 20 years old, but N16 owners specifically call out the sway bar bushes and sway bar end-link (connecting rod) bushes as cracking prematurely. Lower control arm bushes are also mentioned as needing periodic replacement. Clunking over speed bumps or a wandering steering feel is the usual symptom. Budget $200–$500 for a full set of sway bar components fitted, or more if control arm bushes are included.
B17/C12 CVT transmission problems
The CVT fitted to the B17 Pulsar sedan and C12 hatchback — the JF015E unit — is the single biggest reliability concern for the later generation and the subject of widespread owner complaints on ProductReview.com.au and Whirlpool forums.
Reported symptoms include sudden shuddering or violent jerking when accelerating from low speed, noticeable lag before power is delivered, a hard "clunk" during acceleration or deceleration, rattling at idle (indicating early belt or pulley wear), and in some cases complete transmission failure. Most failures occur around 100,000–140,000 km — often just outside the original warranty period. In May 2013, Nissan Australia initiated a service campaign covering approximately 9,272 B17 Pulsar sedans with 1.8-litre engines and CVTs. Some owners report needing multiple transmission replacements. Nissan Australia has in some cases contributed to out-of-warranty replacement costs when owners have pushed the matter, though this is not guaranteed. A rebuilt CVT typically costs $3,500–$5,000 fitted; a used unit starts around $2,500–$3,500 fitted. Regular CVT fluid changes — every 40,000–60,000 km — are essential.
B17/C12 1.6 turbo DIG-T engine concerns
The HR16DE 1.6-litre turbocharged DIG-T, offered in Pulsar SSS variants from around 2014, brings its own watch points. Some owners flag the turbocharger as a potential failure point beyond 80,000 km, with symptoms of power loss and exhaust smoke. The direct-injection system is also prone to carbon build-up on intake valves — a known characteristic of GDI engines — causing rough running if not addressed. These concerns are less widely documented in Australian forums than the CVT issue; treat them as a watch point rather than a certainty.
Air conditioning
Air conditioning issues appear on both generations. On the N16, intermittent aircon failure has been traced to coolant fan relays (R17 and R18 in the underbonnet fuse box) and worn compressor clutch components. On the B17/C12, some owners report compressor failures, with replacement costs potentially reaching $1,500–$3,000 fitted. Test the aircon cold on any used Pulsar before purchase.
Recalls & safety
The N16 Pulsar (2000–2005 production years) is subject to the Takata airbag recall — one of the most significant safety campaigns in Australian history, with approximately 20,720 N16 Pulsars affected. The passenger-side inflator can rupture in a collision and propel metal fragments toward occupants, causing serious injury or death. The ACCC classifies this as a critical recall. If you own or are buying an N16 Pulsar, confirm the recall has been completed — contact Nissan Australia or a Nissan dealership if in doubt.

Buying a used Nissan Pulsar? What to check
- N16 (2000–2006): Cold-start the engine and check for white smoke or misfires — head gasket and coil packs are the key faults. Look for milky oil or coolant residue. Confirm the Takata airbag recall has been completed. Inspect radiator end-tanks for cracks and bounce each corner for sway bar bush clunks.
- B17/C12 (2013–2017): Drive from cold and at highway speed — any CVT shudder, jerk, clunk, or hesitation is a red flag. Ask for all CVT fluid service records; undocumented cars are high risk. Confirm the 2013 CVT service campaign was completed on 1.8L models. On the 1.6T DIG-T, listen for turbo surge or unusual exhaust smoke.
- Obtain a full service history and run a PPSR check or VIN check to confirm there is no finance owing and the car has not been written off.
The verdict
The N16 Nissan Pulsar was a dependable small car in its time. Well-maintained examples still make practical used transport, but the head gasket, coil packs, and crank sensor are the three issues to verify before purchase — and the Takata airbag recall must be confirmed complete. The B17/C12 generation is a more nuanced proposition: the CVT is genuinely problematic, and buyers should budget for eventual transmission work or walk away from cars without a service history. If the CVT checks out and the price reflects the model's reputation, these later Pulsars offer a well-equipped small car at a competitive price — just go in with your eyes open.
