The automatic transmission my default to a "limp-in" mode due to a faulty transaxle input speed sensor. Our technicians tell us there is an updated speed sensor available to correct this condition.

Most reported Dodge Spirit problems
The turbocharger may fail resulting in any of the following: Excessive smoke from the exhaust, lack of power, or grinding or scraping noise from the turbocharger. Our technicians tell us the most common causes of turbocharger failure are lack of oil changes, hard acceleration when the engine is cold, and lack of a cool down period are high speed driving or excessive loads.
Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
4 cylinder engine timing belts can be affected by driving in very hot climates. Our technicians tell us that replacement should be considered before the recommended 60K interval. Replacement timing belts have been designed for greater durability. It is also recommended the belt tensioner be replaced whenever the timing belt is replaced.
A tappet/lash adjuster noise may be noted from the 3.0L engines. Our technicians tell us that proper testing of the lash adjusters should be performed before replacing any parts. A full crankcase of clean engine oil is necessary before attempting to determine if any lash adjusters are bleeding down and causing a noise concern.
Engine oil leaks may develop from the following areas: Valve cover gaskets, cam plugs at rear of the cylinder head, cam seals, front crankshaft seal, and the oil filter bracket. Leaking seals and gaskets should be replaced. Due to mis-machining of the mating surfaces, as special gasket is required to correct the oil filter bracket leak.
4 cylinder engines may develop one or more of the following concerns: Erratic idle, hesitation, and lack of power. Common causes include: Faulty throttle position sensor, brittle or broken wires & corroded or spread terminals in the engine wire harness, cracked or swollen vacuum hoses, and oil contaminated o2 sensors. Our technicians recommend a complete inspection including diagnoses of any stored fault codes if these driveability concerns occur.
4 cylinder engines may develop driveability issues and illuminate the Check Engine Light due to engine vacuum leaks. These vehicles use plastic vacuum lines which can become brittle due to heat and age. Care should be taken when replacing these lines as some may have a restrictor orifice molded inside. If lines are replaced without including the restrictors driveability issues will remain.
4 Cylinder engines may exhibit an erratic idle with the Check Engine Light illuminated. These conditions are most commonly present during cold engine operation in rainy weather. Our technicians tells us that there is an updated idle air control valve available to correct this concern.
A hesitation on acceleration may be caused by a plugged EGR valve back pressure tube. EGR valve replacement is not generally required.
A loud snapping noise may be heard from the exhaust after the engine has been shut off. Replacing the exhaust pipe may be necessary to correct this issue.
Various driveability concerns can be caused by deposits on the back of the intake valves. Fuel injector cleaner has shown reasonable results cleaning light deposits.
