Your Trusted Jeep Repair Shop in Cedar Rapids
Whether you drive a Wrangler on the trails, a Grand Cherokee on the highway, or a Gladiator to the job site, Cedar Automotive provides expert Jeep repair and maintenance you can rely on.

Jeeps are built for adventure, but Iowa roads, salt, and weather take a toll. We handle everything from routine oil changes and brake service to diagnosing the dreaded death wobble, tracking down electrical faults, and servicing 4WD systems. We also inspect aftermarket lift kits and suspension modifications for safety and proper alignment. Cherokee, Compass, and Renegade owners trust us for reliable daily-driver maintenance too.

Common Jeep Issues We Diagnose and Repair
Wrangler Death Wobble
Jeep Wrangler JK and JL owners know the term — a violent front-end shimmy after hitting a bump at highway speed. The cause is usually a worn track bar bushing, loose control arms, or failed steering stabilizer. We inspect every front-end component under load, identify the actual cause, and replace the failed parts so the wobble does not return.
3.6L Pentastar Rocker Arm Failure
Jeep Wrangler JK, Grand Cherokee, and Cherokee with the 3.6L Pentastar develop dropped rocker arms that cause a top-end tick, P0300 / P0306 misfires, and potential valve damage. We pull the valve cover, inspect the rocker arms and lash adjusters, replace the failed components, and confirm valve clearance across the bank before buttoning up.
Pentastar Cylinder Head (Left Bank)
Early 2011–2013 Jeep Wrangler, Grand Cherokee, and Cherokee 3.6L engines suffered left-bank cylinder head failures that drop a valve seat. A P0306 misfire that will not clear with plugs and coils is the hallmark. We confirm with a scope, quote the left head replacement, and use a Mopar-approved head assembly so the repair is permanent.
ZF 8HP Transmission Service
The ZF 8-speed automatic in Grand Cherokee, Wrangler JL, and Cherokee needs fluid and filter service around 60,000 miles. We use the correct ZF LifeGuard 8 fluid, perform the fill at temperature, and reset adaptation values so shifts learn cleanly afterward. Skipping this service is the top cause of early 8HP failure.
Cooling System & Water Pump
Jeep 3.6 Pentastar and 5.7 Hemi engines develop water pump weeping and thermostat housing cracks, especially after 90,000 miles. Left alone, coolant loss at highway speed cracks the cylinder head. We replace the water pump, thermostat housing, and radiator hoses together, then pressure-test before filling with the correct Mopar coolant.
Rust on Unibody and Frame
Older Jeep Wranglers and Cherokees suffer frame and unibody rust in the Iowa salt belt, particularly around the skid plate mounts and rear frame rails. We inspect for structural rust, repair brake and fuel lines that have corroded, and advise on frame repair versus replacement for vehicles on the edge.

Frequently Asked Questions
Can Cedar Automotive diagnose and repair Jeep death wobble?
Yes. Wrangler JK and JL death wobble is one of our most common Jeep repairs. We inspect the track bar, control arm bushings, steering stabilizer, ball joints, and tie rod ends under load — not just by eye — to find the actual cause. Throwing parts at a death wobble without a real diagnosis wastes money. Call Cedar Automotive at (319) 450-7584 for an honest front-end evaluation.
Do you service the Jeep 3.6L Pentastar rocker arm issue?
Absolutely. Dropped rocker arms on Jeep Wrangler JK, Grand Cherokee, and Cherokee 3.6L engines are a common repair for us. We inspect the affected cylinder, replace the failed rockers and lash adjusters with updated Mopar parts, and verify valve clearance across the bank before reassembly. Catching the tick early saves the camshaft.
Can you service the Jeep Grand Cherokee ZF 8HP transmission?
Yes. ZF 8HP fluid and filter service every 60,000 miles keeps the 8-speed in Grand Cherokee, Wrangler JL, and Cherokee alive indefinitely. We use the correct ZF LifeGuard 8 fluid, fill at the proper temperature, and reset transmission adaptations so shifts relearn smooth. Skipping this service is the fastest way to kill an 8HP.
Do you program Jeep keys and fobs without the dealer?
Yes — we cut and program Jeep Wrangler, Grand Cherokee, and Cherokee SKIM transponder keys and proximity fobs at a fraction of dealer pricing. Cedar Automotive carries dealer-level Mopar access so we can handle spare keys, replacement fobs, and most all-keys-lost situations in-house. Call (319) 450-7584 to verify your Jeep model year before visiting the shop.
