Jeep Trackhawk Problems: 2018–2021 Buyer's Guide

The Jeep Grand Cherokee Trackhawk was built for four model years, 2018 to 2021, on the WK2 Grand Cherokee. It took the 6.2-litre supercharged Hellcat V8 (707 hp / 875 Nm in US trim, 710 PS in European trim), put it in a five-seat family SUV with all-wheel drive, and ran 0–100 km/h in about 3.5 seconds. Nothing like it will be made again. The next Grand Cherokee (WL) dropped the V8 altogether.

That rarity keeps values high, and it makes the used-buying question simple: the engine is rarely the problem. How the car was driven is. A Trackhawk that has been launched hard every weekend and one that has done school runs can look identical, but they are very different cars to own.

The engine: tougher than its reputation

The Hellcat 6.2 is a pushrod Hemi V8 with a 2.4-litre twin-screw supercharger. It's a proven design shared with the Challenger and Charger Hellcat, and on a stock, properly serviced car it's durable. The things to know:

  • Supercharger snout bearing / isolator noise. At higher mileage some blowers develop a rattle or chatter at idle that goes away with revs. It's a known wear item, not a catastrophe, but a rebuild is typically $1,500–$3,000 / €1,500–€3,000 at a specialist.
  • Lifter tick. Hemi V8s have a lifter-failure history, and a persistent tick that doesn't clear once warm is worth a specialist's opinion before you buy.
  • Oil and fuel. It needs the correct full-synthetic oil and premium fuel. Expect around 11–13 mpg US / 18–21 L/100 km in mixed driving, and much worse if you use the performance.

Tuned cars are the exception. A smaller supercharger pulley, an E85 flex-fuel tune or a "Stage 2" flash is extremely common on Trackhawks, and it moves the risk from "normal" to "unknown". More boost puts more load on everything behind the engine, which is where the real problems are.

The weak point: the driveline

The Trackhawk's AWD system was strengthened over the regular Grand Cherokee: a heavy-duty ZF 8-speed automatic (8HP95), a single-speed active transfer case, a reinforced rear axle and an electronic limited-slip rear differential. It was designed around 707 hp on the road, not repeated launches on sticky tyres, and not 850+ hp from a tune.

What fails, roughly in order of how often owners report it:

  1. Front differential and front axle shafts. The most talked-about Trackhawk failure, strongly linked to launch-control abuse and drag-strip use. Expect roughly $2,500–$5,000 for a replacement front diff, more for upgraded aftermarket units.
  2. Transfer case. Hard launches, and running mismatched or unevenly worn tyres, stress it. On any AWD car, tyres with different rolling diameters make the transfer case fight itself constantly. Replacement runs about $3,000–$6,000.
  3. Driveshafts and rear differential. Less common, but a clunk or vibration at speed on a car with drag-strip history should be taken seriously.

The practical rule: a stock Trackhawk used as a fast road car is a reasonable ownership proposition. One with drag slips in the glovebox, a tune and a stack of "upgraded" driveline parts may be fine, but you're buying someone else's experiment.

Running costs that surprise people

Nothing here is a fault. It's just what 2.4 tonnes and 700+ hp cost to run:

  • Brakes. Six-piston Brembo calipers at the front with 400 mm rotors. A full front rotor-and-pad set with genuine parts easily reaches $1,500–$2,500 / €1,500–€2,500.
  • Tyres. 295-section performance tyres front and rear. Driven with enthusiasm, a set can be gone in 10,000–15,000 km / 6,000–9,000 miles.
  • Suspension. The Trackhawk uses adaptive Bilstein dampers on steel springs, not the regular Grand Cherokee's Quadra-Lift air suspension. That's good news: it removes one of the WK2's most expensive failure points.
  • Uconnect screen. The 8.4-inch Uconnect touchscreen on WK2s is known for delamination and "ghost touches". Check it works everywhere on the screen.

Which year to buy

Honestly, the year matters less than on most cars. The Trackhawk ran for four years with the same drivetrain, and changes were mostly colours, packages and minor equipment. That makes the choice about the individual car:

  • 2018: first year, and usually the cheapest entry. Check every recall has been done (see below). Early cars are also the most likely to have been through several owners and tunes.
  • 2019–2020: the same mechanicals with production refinements. Often the value sweet spot.
  • 2021: final year. Holds its value best, and a low-mileage, unmodified 2021 is the collector's pick. You pay for that.

Whatever the year, mileage, modification status and history matter more than the model year. A 2018 with a documented stock history beats a tuned 2021 as a purchase.

The free checks to do at the viewing

About five minutes, no tools:

  1. Look for a tune. Open the bonnet: an aftermarket (smaller) supercharger pulley, a catch can, an aftermarket intake or a tuner device plugged into the OBD port all point to a modified car. Ask directly, and ask for the original file if it's been tuned back to stock.
  2. Check the tyres. Same brand, same model, similar wear on all four. Mismatched or unevenly worn tyres on an AWD car mean the transfer case has been stressed, and they suggest how the car was looked after.
  3. Listen at cold start. A rattle from the front of the engine that fades with revs points to the supercharger snout. A tick that doesn't clear once warm points to the lifters.
  4. Drive it slowly, then briskly. At full lock in a car park, listen for clunks or binding from the front. Shift between Drive and Reverse and feel for a heavy clunk. At motorway speed, feel for a vibration that changes with speed rather than revs.
  5. Look for drag-strip evidence. Timeslips, heavy wear on the rear tyre shoulders, or a seller who talks about quarter-mile times. None of it is disqualifying on its own, but it tells you which failure list to worry about.
  6. Confirm it's a real Trackhawk. SRT models with Trackhawk badges and painted yellow calipers do exist. The VIN and the original build sheet settle it in seconds.

Imports, recalls and the history check

Many Trackhawks outside North America are US imports, and a meaningful share of US imports carry salvage, flood or rebuilt titles that can disappear once the car is re-registered. Our guide to US and Canadian import title brands explains what to look for, and US-spec vs EU-spec differences covers lighting, emissions and resale.

WK2 Grand Cherokees were covered by several recalls during these years, so check the VIN against the NHTSA recall database and make sure every campaign shows as completed. A VIN history check will show title brands, accident records and mileage history. AutoFindr readers get 20% off carVertical with code AUTOFINDR.

Bottom line

Driveline riskModerate: watch tyres and servicingHigh: front diff, transfer case
Running costsHigh, but predictableUnpredictable
VerdictThe one to buyOnly with receipts and a discount

The Trackhawk is a far better used buy than its hooligan reputation suggests, if you buy a standard one. The engine is the strong part. Budget for tyres, brakes and fuel, walk away from vague histories and heavy modifications, and a well-kept example is one of the last great V8 SUVs.

Run the exact car through the AutoFindr analyzer for its reliability score, the documented failure modes at that mileage and a fair-price band. Estimate the next few years with the maintenance cost estimator, and see how it has held its value compared with rivals in the depreciation calculator.
