. "sporadic" problem with the car developing a violent shake when traveling between 50-70mph. Problem has only been detected sporadically when going up/down inclines on interstate. Car loses momentum when problem occurs requiring me to completely let off gas and drop car into neutral to regain momentum. Cannot recreate problem at will, only occurs sporadically.. problem has occurred over 20 times since mid December 2009. Car has been taken on 7 separate occasions to local Dodge dealership where purchased (bob frensley chrsyler/Dodge). Five of these occasions invoicable work was performed as noted below. Dealership claims they can no longer recreate the problem and refuse to work on the car any longer. Problem has been reported to Dodge customer care with 2 separate cases being opened. Dodge customer care refuses to authorize any further work unless the dealership acknowledges that they can recreate the problem.. both Dodge customer care and the dealership have verbally recommended the following solution: "continue to drive the car until the problem worsens and then bring it back to be serviced".. each time the car has been returned to me the problem has recurred within 3 days invoices: #1 (01/08/2010). Replaced fuel injector due to P0304 code cylinder #4 misfire. Replace left rear tire due to nail in tire (covered by extended warranty) #2 (01/18/2010). Flash upgrade torque converter (performed, not listed on invoice). Wheel balance (both front, both rear). Mount match wheel to tire (each wheel) #3 (01/26/2010). Replaced torque converter. Remove and reposition molding/windshield A-pillar #4 (02/12/2010). Flash upgrade torque converter (performed, not listed on invoice). Replace 4 low tire pressure sensors. Cross switch all tires. Front end/rear wheel alignment #5 (02/22/2010). Added antifriction modifier to transmission. Test drove vehicle and could not recreate problem.
