NEWMAR Complaints

TPMS has not been functioning correctly since October 2021. The rear wheels will randomly loose communication causing the TPMS display form that tire to disappear. (No Pressure reading). I have taking it to the Dealer NRIVC in Atlanta, GA., they added a second antenna in the rear. This did not fix the problem. I then took the Coach back to the manufacturer Spartan; they moved the antennas to the outside of the vehicle frame. This also did not fix the problem. This is a safety problem as you cannot see if tire is losing pressure, and the pressures that you do see you cannot trust as the problem randomly will occur in all rear wheels.

What component or system failed or malfunctioned, and is it available for inspection upon request? Tire pressurre monitoring system (TPMS) has not functioned properly since the day the vehicle was delivered. Drive and tag axle tire pressures and temps won't display reliably. The inner tire pressure on the driver's side of the drive axle has never displayed. Other drive and tag axle tire info displays intermittently in no obvious pattern-appears and disappears unpredictably. The TPMS can be inspected. How was your safety or the safety of others put at risk? Operating the vehicle with over or underrinflated tires or tires that are too hot can compromise the tires and cause a blowout and loss of control of the vehicle placing our safety and the safety of others at risk. The TPMS mitigates this risk to safe operation. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealer (Independence RV in Winter Garden, FL) has made at least two attempts to correct these TPMS issues without success. They have consulted with Spatan technicians and suggestions for correction have been made by Spartan and the suggestions have been implemented by the dealer without success. In conversations with me, Spartan technicians have acknowledged there are known common issues with my installed "Gen 1" TPMS system manufactured by Valor which have been addressed by Valor's "Gen 3" system which Spartan is currently installing. Spartan has no current plans to switch my TPMS to a "Gen 3" system even though they feel this would eliminate the safety issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Just the RV dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The problem was apparent by way of a failure of tire pressures and temps to display correctly on the instrument cluster.

On numerous occasions the dash warning light will come on stating "Service Advance Trac". When this happens traction control, hill assist & cruise control all shut off without any warning. Sometimes the ABS light illuminates also. Ford does not seem to have a fix for this problem as it has effected many newer F53 chassis. Ford tells customers to just stop for a few minutes & cycle the key. It clears it for a little while but always comes back on. No trouble codes show up when scanning with an OBD2 scanner. Ford say they are working on a fix coming soon, but they have been saying that for the past two years, but no fix yet. When the cruise control shuts off suddenly it can be quite alarming and the traction control being inoperable could cause skidding if conditions are right.

Multiple double pane windows are fogging. The driver’s side window fogging between the double pane glass, is causing visibility problem’s creating a safety hazard.

Dual Paine Window glass separating on Exterior Windows. Safety Hazard if the outside glass were to come off while traveling. Hehr is the manufacturer that Newmar used for the windows. Newmar is stating the Windows are not covered as the Vehicle is out of warranty. Reviewing many RV Forums it is evident that this problem with Hehr windows on Newmar Class A Motorhome is a common problem.

The 2023 Newmar Dutch Star 4326 with a Freightliner Custom Chassis was built without an exterior temperature gauge. This is the first vehicle I've seen like this in many years. I'm on our first trip with my family onboard and we're driving thru the NC mountains in a wintery mix with temperatures varying from above to below freezing. I'm very nervous not knowing when the roads will begin to ice over on treacherous roads. I've discussed with Newmar and Freightliner and they both just say they don't know why it's not there and that they cannot add it. I see this as a major safety issue and recommend a recall to have them installed. There are many people driving these 52,000 lb rigs who do not have much experience. Please help us save lives.

The hydraulic steps on this motor home automatically extend and retract when the door is opened or closed. The steps on this unit failed to retract after closing the door, and as I drove away, the steps hit a fence post. They could just as easily hit a person or driving down the road hit another vehicle. There is no warning system on this vehicle to warn the steps did not function as designed, and they are not readily visible from the driver seat. My understanding is that this has happened to others.

The Valor TPMS system on the Freightliner chassis has not worked correctly for as long as I have owned the coach. I was hopeful that recent recall work performed by a Freightliner service center on the system would help but it actually made the system worse. As was prior to the recall work several of the sensors still fail to report their pressures completely, others report only sporadically. This essentially renders the system useless as the driver may not be made aware of a loss of tire pressure while driving. Additionally, since the recall work was performed, a high pressure warning now displays when the tires heat up in normal driving conditions. This warning is distracting and appears separately for each tire. When the warning appear it blocks the digital speedometer and other vital information on the dashboard from displaying until the warning is cleared manually.

UNKNOWN I was traveling in this new to me 2020 Newmar London Aire on a trip of approx. 2,700 miles. The first issue was coming to a bridge in SC that was maybe 400 feet in length. There were lots of transition strips and dips on the bridge. When I first approached the bridge, my Motorhome bounced/propoised so violently that my wife flew up out of her sit and the front end dropped to the stops on the frame. I have been MHoming since 1999 and have never experienced this type of bouncing. I was scared and the MH continued to bounce on this bridge for another 6-8 times, although not as violent as the first bounce. We experienced this bouncing/porpoising many other times on our trip, just not quite as violent as described above. This is a major safety issue and it has to do with improper shocks/ no sway bar on the front axle. The chassis is Spartan and I talked to them about the problem but they played dumb, even though I have communicated with many other MH owners who have experienced this same problem with this K3 Spartan Chassis. Those owners have also talked to Spartan and have not gotten any satisfaction.

Tire Pressure Monitor System stops working after 1 to 2 hours and shows all tires at 401 degrees F and 136 PSI. At this point there is no warning if a tire loses pressure or overheats which could lead to a blowout and accident.
